I was 86% correct on accurately

0:02

predicting when an NBA team will be at

0:04

highest risk of losing strictly based on

0:06

the sleep oh gosh yes and just 15 or 30

0:10

minutes can make a difference so let's

0:12

dive into just some very practical

0:14

strategies to get the best sleep

0:16

possible Dr sharim ma is a renowned

0:18

sleep doctor and performance expert

0:20

whose sleep optimization research has

0:22

enhanced the careers of CEOs as well as

0:24

athletes in the NFL MLB and Formula 1

0:27

and has provided lifechanging expertise

0:29

to companies like under aror and Google

0:31

for my Elite athletes that I work with

0:34

sufficient sleep it's a game Cher for

0:36

example we saw 12% faster Reaction Time

0:39

a 9% Improvement in free throws and a 4%

0:42

increase in Faster Sprint time and when

0:45

you experience what it feels like to be

0:47

well rested you never want to go back

0:49

getting insufficient sleep and it

0:50

doesn't have to be these big jumps I'd

0:52

love to dig into that okay so i' have a

0:54

shower then I get straight into bed

0:55

after is that good or bad tweak the

0:57

timing of your shower and your hot bath

0:59

to just an hour or two before bed it's

1:02

hard to grasp how much of a difference

1:04

this can make in your life what about

1:06

sex does it have an impact on your sleep

1:09

okay so is there anything that I can eat

1:11

before bed that won't disrupt my sleep

1:12

but will get rid of The Hunger there's a

1:14

pre-sleep meal for example cereal and

1:16

milk cereal and the reason why is

1:18

because and then I read this fascinating

1:21

word nappuccino yes this is a useful

1:23

tool if you're a working professional

1:25

and you need a little boost and

1:26

alertness and performance what you do is

1:31

the DI of AO raffle is about to close

1:35

anyone that subscribes to the DI ofo

1:36

before we hit 7 million subscribers

1:39

which is probably going to be in a

1:40

couple of days time you will be included

1:42

in the raffle and on the day we hit 7

1:44

million subscribers we are giving away a

1:46

lot of money can't buy prizes to all of

1:49

you so hit the Subscribe button get in

1:51

before 7 million and I'll announce the

1:53

prizes and the winners in the comments

1:55

below when we hit 7 million subscribers

1:58

[Music]

2:01

Dr M what is it you do and why is it so

2:07

important in your mind that you do

2:09

it great question so I am a sleep

2:12

physician um but I spend a lot of my

2:15

time and career trying to educate and

2:18

and advocate for people to prioritize

2:21

sleep right this fascinating process

2:23

that each of us does every single night

2:25

and arguably is about a third of our

2:27

lives but many individuals don't do this

2:30

very well or they you know sacrifice it

2:32

and overlook this area I very much

2:35

believe if you don't sleep your best you

2:38

will not be your best or counter to that

2:41

is if you your if your sleep is best

2:44

you'll be at your best and what that

2:46

means if I unpack that a little bit more

2:48

is we often are sacrificing our sleep

2:50

we're underslept we often don't have

2:52

good quality sleep it we're very

2:55

reactive to our sleep at night time and

2:57

it's the last thing that we think of at

2:58

the end of the day when we wrap

3:00

everything up um and that's arguably not

3:02

going to put ourselves up to be the best

3:05

we can be in the following day right and

3:08

for my Elite athletes that I work with

3:10

when you actually get sufficient sleep

3:13

you have practices that you plan into

3:16

your day and you actually are more

3:18

proactive with that it can be a game

3:21

Cher and for them when it comes to

3:23

performance on the field that can be the

3:25

difference of a 9% Improvement in free

3:28

throw shots it can mean reacting 12%

3:31

faster and so until you experience that

3:35

it sometimes is hard to grasp how much

3:37

of a difference this can make in your

3:39

life but it is one of the foundations

3:42

that will impact everything about how

3:43

you function your mood how you feel and

3:46

ultimately perform the following day if

3:49

I could offer you or yes you

3:51

specifically see if I could offer you

3:53

something that's free and healthy and

3:56

safe that's going to help you think more

3:59

clearly make better decisions be in a

4:02

better mood be more productive and

4:04

efficient would you want it of course

4:07

how much exactly and so it's really a

4:10

decision of whether you want to invest

4:13

uh your time to be able to be more

4:14

proactive with this particular area of

4:17

your life to get the benefits that come

4:19

down the road with it who do you work

4:21

with give me a sort of broad spectrum of

4:24

the individuals organizations that

4:26

you've worked with on sleep and why have

4:29

they come to you I've had an opportunity

4:32

to work with a number of professional

4:34

sports teams and athletes as well as

4:36

organizations over the years to try and

4:38

apply the science into practice to help

4:41

them improve their sleep their

4:42

scheduling and their travel so for

4:44

example I've been with the San Francisco

4:46

Giants in Major League Baseball I've

4:49

worked with um NBA teams like the Golden

4:51

State Warriors uh NFL teams like the

4:54

Philadelphia Eagles I won a Super Bowl

4:56

ring in 2017 with them to um other

5:00

sports organizations like Nike and under

5:03

arour and ESPN to try and show how you

5:06

can predict when NBA teams will lose

5:08

strictly based on the schedule and

5:11

insufficient sleep opportunities um to

5:13

individual athletes who recognize you

5:15

know hey this is an area that I am not

5:19

optimizing and I know this can be such a

5:22

valuable asset to extend my career to

5:24

prevent injuries down the road and to

5:26

help me be at my best do you ever work

5:28

with CEOs I do I do work with Executives

5:32

and seite um um Executives to try and

5:35

help them be their best because they too

5:37

are high performers right their

5:39

performance outcomes are maybe a little

5:41

bit different than pro athletes where

5:43

we're quantifying on field performance

5:45

and looking at their swim times and what

5:48

they're doing when it comes to the you

5:50

know onc court or on field um

5:53

performance outcomes but for these

5:54

Executives they arguably are also making

5:56

incredibly important decisions they have

5:58

to still react when they're under

6:00

pressure and they have to make good

6:01

judgment calls and so many of the things

6:04

that I coach and and try to recommend to

6:07

my lead athletes are very much

6:09

applicable to the SE Suite executive or

6:12

even just the working professional

6:14

that's really what what I found so

6:15

fascinating about your research and your

6:16

work is that although there's a focus on

6:19

athletes as someone who is also

6:21

traveling is also very very busy also um

6:25

struggles with sleep sometimes because

6:26

I'm I have to perform late at night

6:28

whether that's on stage or with meetings

6:29

or whatever it might be I resonated with

6:32

so much of it and I also train in the

6:35

gym pretty much every day if I can um

6:38

and I've also noticed a correlation

6:40

between things like injury in the gym

6:43

based on how I'm sleeping in my quote

6:45

unquote sleep de but I but I I want to

6:48

confront two things the first thing I

6:49

want to confront is the misconceptions

6:50

around sleep that you encounter over and

6:52

over again what are the like big

6:54

overarching misconceptions that stand in

6:56

the way of people believing in and

6:59

implementing the advice that you give

7:02

them I'll start with just this badge of

7:05

honor that I really believe still

7:06

persists in society where you should get

7:08

only four or five hours of sleep and

7:10

should be able to perform at your best

7:12

and I think the tides are turning and I

7:14

do think that that is changing over the

7:16

last several years where there are more

7:19

vocal Advocates of um you know Elite

7:23

athletes like the Tom Brady who you know

7:26

say everything is around performance

7:27

enhancement I going need to go to to bed

7:29

early so that I can wake up early and to

7:32

be ready to go for the day to you know

7:34

the Simone bios who says I need to get 8

7:36

hours of sleep and so I think that that

7:39

is a badge of honor that is now shifting

7:41

and now it's going to become well if

7:43

you're not getting your 8 n 10 hours of

7:46

sleep right then you're actually at a

7:48

decrement to yourself and you're

7:50

actually not going to set yourself up to

7:52

be the best that you could possibly be

7:54

whether you're on the field as a pro

7:55

athlete or whether you're leading an

7:57

organization or trying to go after

7:59

whatever ever it is that matters to you

8:01

right and and I think that's going to

8:03

continue to shift but I'm excited about

8:05

it because that's one thing until you

8:07

experience that that difference and that

8:10

life transformation of what it feels

8:12

like to be well rested then it can be a

8:15

game changer you never want to go back

8:16

to it again when you're getting

8:18

insufficient sleep are there any

8:20

misconceptions around how to sleep in

8:22

sleep hygiene and um I know the

8:25

quantities of sleep weeny that also seem

8:28

to stand in people's way

8:29

of them getting a great night's sleep

8:32

yeah so I think that there is a

8:33

misconception that everyone needs a

8:35

certain amount of sleep there's

8:36

individual variability so the the

8:39

recommendation from the American Academy

8:41

of sleep medicine and the Sleep research

8:43

Society so two of our national

8:44

organizations here in the US recommend

8:46

minimally 7 hours of sleep but that's

8:48

the lower threshold you might actually

8:50

need 8 hours or 9 hours or more to feel

8:53

well rested right I I personally feel

8:55

terrible on seven hours and I much more

8:57

need the eight to nine hours and there's

9:00

those in that individual differences so

9:02

you need to find what you feel well

9:04

rested you're able to function well at a

9:07

high level during the day and that will

9:10

then be your individual requirement so I

9:12

think there's this misperception that

9:14

everyone needs a certain amount but you

9:16

need to find what works for you and it's

9:17

all about small changes so if you're not

9:20

at 7 hours I think you shared sometimes

9:22

you're you're you're under that oh yeah

9:23

sometimes yeah you know it's about F 15

9:27

or 30 minutes more can make a difference

9:29

refence so if you're getting 6 hours

9:31

then I'm going to recommend getting 15

9:33

minutes or 30 minutes more every day for

9:36

this one week and then get 15 or 30

9:38

minutes more next week so that you're

9:40

building from say 6 hours of sleep to 6

9:42

and a half hours and you may not think

9:44

that that's that much but we can all do

9:46

15 minutes more right we're less

9:47

scrolling or doing what we're wrapping

9:50

up our day but those 15 minutes add up

9:52

where that's a difference of like an a

9:54

student to a b student or 11 minutes

9:56

more sleep is the difference of a b

9:58

student to a c student in one of these

10:00

studies really exactly and then over the

10:03

course of a week 15 minutes will be

10:05

almost 2 hours more sleep than if you

10:08

didn't what was the study so this was a

10:10

study done um in high school students

10:13

but looking at the difference of how

10:14

much they're sleeping versus their

10:17

correlation to to grades and so that

10:19

15minute difference was shown to be that

10:22

A to B student 11 minutes from that B to

10:24

C student oh gosh yes so it doesn't have

10:28

to be these big jumps

10:29

but small changes over time will will

10:32

add up the the study I have in front of

10:34

me here which I've printed out um also

10:37

highlights the importance of sleep for

10:39

everybody but also specifically in this

10:41

case for athletes can you walk me

10:44

through this study and what you found in

10:46

this particular study on the adult male

10:48

basketball players yes and how you

10:50

conducted the study so in the study we

10:53

looked at the men's basketball team and

10:55

we really tried to examine if we

10:57

extended their sleep over 5 to 7 weeks

11:00

encouraging them to get 9 or 10 hours of

11:03

sleep every single night to B pay back

11:06

what we call an accumulated sleep debt

11:08

would we see any impact on performance

11:11

outcome specifically would we see an

11:13

impact on reaction time their fatigue

11:15

levels and would we see an impact on

11:18

their onc Court performance specifically

11:20

free throw shots three-point shots

11:22

Sprint time and these are measures that

11:25

we would do after every regular practice

11:28

and over the course of those 5 to 7

11:30

weeks we demonstrated that we saw a 9%

11:32

Improvement in free throws a 9%

11:35

Improvement in three-point shots we saw

11:37

a 12% faster reaction time and a 4%

11:41

increase in uh faster Sprint time and so

11:45

these were the quantification which was

11:48

novel at the time was what was quite

11:49

fascinating because it wasn't that 1%

11:52

that I think many Elite athletes are

11:54

trying to find every small way to adjust

11:57

their training to get that 1% better

11:59

better because in Elite Sport that 1%

12:01

can be the difference right of being at

12:03

the top versus not but this was arguably

12:06

9% or even double digits for Reaction

12:09

Time depending on the outcome and so

12:11

we've expanded that looking at other

12:13

sports as well but this was one of the

12:14

first ones to show that it really

12:17

potentially could have a significant

12:18

impact on performance outcome for these

12:20

athletes how much did they sleep more

12:22

per night to get those results yeah so

12:25

they did so we did quantify objectively

12:27

through a uh what's called actigraphy it

12:30

looks like a wearable nowadays um and

12:33

then compar that also with what they

12:34

thought they were getting and so we did

12:36

extend their sleep um uh substantially

12:39

over I believe an hour and a half uh

12:42

compared to what they were getting prior

12:44

to the study because getting 9% more

12:47

free throws or three-point shots or 12%

12:51

better reaction time is quite frankly

12:53

for some teams the difference between

12:55

like winning a championship and not yeah

12:57

because I think about the Premier League

12:58

often which is it's soccer I guess

13:01

football um often time there's been

13:04

leagues within my lifetime there's been

13:05

years in my lifetime where both teams

13:07

have um tied with the same amount of

13:09

points and one is one just on the amount

13:10

of goals they've scored they've just

13:12

scored a couple more goals so after 38

13:14

games they both have the exact same

13:16

points and the winner is just the person

13:17

that scored like a couple more goals but

13:20

even you think of reaction times you

13:21

think of goalkeepers in in soccer their

13:23

whole game is reaction time so if you

13:25

can increase your reaction time by 12%

13:27

it's really really staggering

13:30

it can be a game changer and I think

13:31

that's what has been so fascinating with

13:33

some of the athletes or organizations

13:35

and teams I've worked with who have made

13:37

it to the most important games and those

13:40

championships because the hope is that

13:43

you've invested not just the night

13:46

before that championship game but you've

13:47

invested an entire season even starting

13:50

in the off season on cultivating better

13:52

habits to give yourself that foundation

13:55

and be able to leverage these strategies

13:57

that the other team is not because we

14:00

know that it significantly can impact

14:02

not just the individual level on

14:04

performance outcome but organizations as

14:06

a whole and I think one example of that

14:08

is um I partnered with ESPN to do what

14:11

was called the NBA schedule alert

14:13

project where they ask can you predict

14:15

Dr ma when NBA teams are going to be at

14:18

risk of losing games strictly based on

14:20

the schedule so not factoring in

14:23

strength of team but based simply on

14:26

their schedule where they're traveling

14:28

to how many times are crossing these

14:30

various factors does it affect

14:32

organizations as a whole and teams and

14:35

their game outcomes as you mentioned and

14:37

over three seasons I was 76 to 86%

14:40

correct on accurately predicting when an

14:43

NBA team will be at highest risk of

14:45

losing strictly based on the schedule so

14:47

in the spirit of the project we didn't

14:49

factor in strength of team but to me

14:51

that was staggering because there's many

14:54

other factors that maybe are not always

14:56

considered to be as clearly important

15:00

about you know this travel schedule up

15:02

front but hey maybe these factors really

15:04

do play and influence um game outcomes

15:07

in this way and that's not the only

15:08

thing that has obviously shown that

15:11

organizations and teams as a as a whole

15:13

will have differences performance

15:15

outcome there's other studies like the

15:17

Monday Night Football study that showed

15:19

if you simply bet on a West Coast team

15:23

when they play an East Coast West Coast

15:25

matchup during night games over 25

15:28

seasons you'd beat the Las Vegas point

15:30

spread 68% of the time and so if you're

15:33

able to predict with with greater

15:35

accuracy then obviously there is

15:37

potentially some gambling outcomes that

15:39

could work in your favor here but really

15:41

being able to show that you would be

15:43

able to benefit and predict better than

15:46

what the spread will be between the the

15:48

two teams over is that because the West

15:51

sorry the West Coast team has gone which

15:54

who's who's traveled it doesn't matter

15:56

it simply matters that the West Coast

15:58

team is playing the east Coast team

15:59

during night games so this can happen on

16:01

the west coast it can happen on the East

16:03

Coast the reason why is because

16:04

performance is enhanced in the late

16:06

afternoon to evening around 4: to 8:00

16:09

in both scenarios the body clock of the

16:12

West Coast team because they typically

16:15

go out just the day before the game it

16:18

feels like they're on the west coast

16:20

okay right so when you're a West Coast

16:23

team and you stay there and the East

16:25

Coast team comes out the East Coast is

16:27

three hours later so what is a seven

16:29

o'clock game on a West Coast feels like

16:32

a 10 o'clock game for a East Coast team

16:34

got you same thing applies when the West

16:37

Coast team goes east coast even if it's

16:39

a 7:00 game there yeah the West Coast

16:42

feels like it's a 4:00 body clock yes

16:45

and so that special window of around 4:

16:48

to 8:00 p.m. when world records are

16:49

broken and performance in a 24-hour day

16:53

is is optimal and that is leveraged then

16:56

over those 25 Seasons that the West

16:59

Coast will have more favorable outcome

17:01

overall got you so in this study you did

17:03

in 2011 that was published in 2011 one

17:06

of the things I read as well is that

17:07

players who had slept more in your study

17:11

sprinted

17:13

faster I mean quite quite dramatically

17:15

faster as well I I think from 16.2

17:18

seconds at the start of the study versus

17:21

15.5 seconds at the end yes over what

17:23

distance was that yes so that was from

17:25

the Baseline to half court to Baseline

17:27

to full court and back so we chose a

17:29

very standardized

17:31

sprinting uh sprinting drill that they

17:34

are familiar with that we could

17:36

replicate after every regular practice

17:37

as you imagine not everyone on the team

17:39

was participating on in this study and

17:41

so they did this after every regular

17:43

practice and that ended up being a 4%

17:46

difference in Sprint time that is pretty

17:48

crazy do do do professional teams know

17:51

this do athletes know this are they

17:53

aware of this or is this something

17:54

that's fairly new some are aware and I

17:57

think the momentum is shifting towards

18:00

more athletes more teams recognizing

18:02

that this is an untapped competitive

18:05

advantage that this is an area that they

18:08

may or may not have implemented specific

18:11

strategies or education or or planning

18:14

for when they travel but I think the

18:16

more Forward Thinking organizations

18:19

teams and athletes are starting to pick

18:22

this up and starting to recognize that

18:24

they can use this as a weapon right as a

18:27

performance-enhancing drug if you may

18:29

because it is safe it's healthy it's

18:31

effective and we know that it will be

18:34

one of the only things that can give you

18:36

these performance benefits um and and

18:39

those are the ones that are trying to

18:41

Leverage The Science into application

18:43

for optimizing yeah their sleep at

18:45

nighttime have you seen athletes

18:47

individual athletes change and save

18:50

their careers when I say change I mean

18:52

change the trajectory of their career or

18:54

save their careers because they focused

18:57

on their sleep and can you give me some

18:58

examples of that yes Golden State

19:01

Warriors Andre Iguodala he's someone who

19:03

I worked closely with he came to the

19:05

Warriors back in around 2014 he was

19:09

already an Allstar he was 28 at the time

19:12

knew that his career was going to

19:15

probably be sunsetting at some future

19:17

time but wanted to extend it as long as

19:18

possible but he knew he wasn't doing

19:20

sleep best as possible he was very open

19:24

about sharing how he would stay up till

19:26

the we hours in the morning playing

19:27

video games would sleep for a few hours

19:30

go to practice play for a few hours come

19:32

home and take a 2 to three hour power

19:33

nap and that was his routine for for 10

19:36

years um and he said you know how do I

19:39

improve how I approach my sleep I know

19:41

that this is important as an athlete to

19:44

who wants to play in the league as long

19:45

as possible so I had the opportunity to

19:47

work with him over several months to

19:49

help him recraft how he approached to

19:51

sleep including a wind down routine

19:54

thought about some of his nutritional

19:55

choices tried to shorten his naps time

19:58

them closer to game time to give him the

20:00

Boost and alertness and performance be

20:03

able to manage a racing mind and be able

20:05

to have just a more proactive approach

20:07

to his sleep in a really neat way The

20:10

Following Season the Warriors went to

20:12

the championship for the first time in

20:15

many years they won he came back with

20:17

the finals MVP he subsequently has won

20:21

three more championships with them so

20:23

four in total and extended his career

20:25

for 10 years when we made these changes

20:28

there was a quantification of the

20:30

performance enhancement so a third party

20:32

Quantified as he went from under seven

20:34

to seven and a half to more than eight

20:36

hours he had a two-fold increase in his

20:39

threo percentage he had a

20:42

88.9% increase in his free throw shots

20:46

which very interestingly is the exact

20:48

same 9% that I showed in my man's

20:50

basketball study that had the same 9%

20:54

Improvement in free throws he had a 29%

20:58

Improvement in his points per minute a

21:00

45% decrease in his fowls and so you

21:04

know these numbers are pretty staggering

21:06

again for someone who's already at the

21:08

highest level as an Allstar and it's not

21:10

to take anything away from Andre but he

21:12

has been very vocal about the difference

21:14

this made as he changed these habits it

21:16

he says it changed everything for him

21:19

and I think that that's you know a very

21:21

inspiring story of what it can mean to

21:25

extend your career and be able to almost

21:27

tap into this additional performance

21:29

capacity that I think even he was

21:31

surprised about that he for the first

21:34

time was able to improve beyond what he

21:38

already thought was his best and I think

21:40

that's what's so inspiring because this

21:42

is something that's accessible to all of

21:43

us to be able to tap into that little

21:45

bit more so not only did he win the most

21:46

valuable player award but his

21:48

three-point conversion went up

21:53

218% yes so during the time that I had

21:55

worked with him his three-o percentage

21:57

went up twofold during that time it begs

22:00

the question what did you do to

22:03

him and you know you named a couple of

22:05

things there but I'd love to dig into

22:06

some of those key points sure um where

22:09

you started with him the specific sort

22:11

of implement things that you implemented

22:13

into his um sleep hygiene and so that if

22:17

I am him the day that you met him when

22:20

he was taking those naps and staying up

22:21

late which I often do to be fair um

22:24

where would you start with me and where

22:25

did you start with him okay so let's

22:28

dive into is just some very practical

22:30

strategies that I started to challenge

22:31

him with which was we'll start with his

22:34

sleep environment we want to make your

22:36

sleep environment like a cave really

22:39

dark quiet cool and

22:42

comfortable dark cave so dark blackout

22:46

curtains eye mask are some of the

22:48

easiest tools that you can grab but are

22:50

incredibly helpful and great investment

22:52

to be able to use that both at home and

22:54

then when you travel so that if you're

22:56

in a non-ideal environment like a hotel

22:58

room you have for example an IM mask

23:00

that can help dampen out the the light

23:03

uh making it quiet so

23:05

earplugs uh also a white noise machine

23:07

I'm a huge fan of even a small travel

23:09

white noise so that you can actually

23:11

mask over external noises that you may

23:13

or not be able to control I'm someone

23:15

that tells myself that I sleep with

23:17

something playing for I grew up with a

23:19

radio in my room so when I'm as an adult

23:21

now I'm always looking to play something

23:23

as I fall asleep is that going to hurt

23:25

my Sleep Quality I would say if you're

23:27

accustomed to this would say that's fine

23:29

to continue to do so I am not a fan of

23:31

having the TV on and having the bright

23:33

light exposed um to you in that hour

23:36

before bedtime because it also can just

23:38

be very psychologically stimulating but

23:40

if like you said it's a radio or it's a

23:42

podcast that you feel is helping you

23:44

relax then I'm a fan of it do you think

23:46

Daria will help people relax it

23:49

might it might help you at least think

23:51

about your sleep a bit more and

23:53

challenge you to do maybe one one change

23:55

tonight we consider that to be a

23:57

scientific endorsement of of the podcast

23:59

um okay so I've got sound down you are a

24:03

fan of the white white noise machines I

24:05

am because sometimes there's external

24:06

noises like a garbage truck or

24:09

construction that you're not always able

24:11

to control so if you can at least mask

24:12

over it temporarily that can sometimes

24:15

be helpful to keep individuals more

24:17

asleep during the night time and there's

24:19

even some now that are adaptive so if

24:21

the door slams then the volume

24:23

temporarily increases and then will

24:25

decrease so there's almost these smart

24:27

white noise machine that are that are

24:29

coming out on the market so that's from

24:31

a noise standpoint and earplugs are

24:33

going to be helpful if you're traveling

24:35

when you're at home you can obviously

24:36

use those to dampen down any external

24:38

noise from a from a temperature

24:40

standpoint you want it to be cool I

24:42

think this is an area that a lot of

24:43

people can benefit from because they

24:45

often sleep in much warmer temperatures

24:47

than what we know is probably more

24:49

conducive to sleep which is cooler 60 to

24:52

67° has been shown to help individuals

24:55

stay asleep and fall asleep that may be

24:58

frigidly cold for some but you have to

25:00

find the temperature that's right for

25:02

you I would say decrease your

25:04

temperature by say one degree or two

25:06

degrees every couple of days and then

25:07

you can find the temperature that works

25:09

well for you and there's even technology

25:11

now where there's mattress covers that

25:13

can help you regulate temperature from

25:17

much cooler to warmer so if there's

25:19

differences in bed Partners that's a way

25:21

that you can actually accommodate both

25:22

of their preferences so that's about 16

25:25

to 20° cus

25:28

what about when I shower or I bath

25:31

because often I go and have a shower

25:33

then I get straight into bed after yes

25:35

is that good or bad I would encourage

25:38

you to shift that timing a little bit

25:40

earlier into the night so an hour and a

25:42

half before you are planning to go to

25:44

bed I would shift your shower because

25:48

when you are taking a hot bath or hot

25:50

shower it increases your core

25:52

temperature but when you fall asleep

25:54

your core temperature drops so you don't

25:56

want that competing signal to be right

26:00

before bedtime but if you back that

26:02

shower up an hour and a half that should

26:05

be sufficient time that we think

26:06

potentially there's an augmentation of

26:08

helping that drop in temperature and

26:11

some smaller Studies have shown that

26:12

that can help decrease the time to fall

26:14

asleep and also enhance deep sleep which

26:17

has implications for Muscle Recovery

26:20

regeneration and you get more of that in

26:22

the earlier part of your night so it's

26:24

an easy fix uh just to tweak the timing

26:27

of your shower in your hot bath to be

26:29

just an hour or two before bedtime not

26:32

right before bed so it's a strategy too

26:33

if you have difficulties winding down

26:36

and relaxing to implement that hot

26:38

shower hot bath earlier in the evening

26:41

one of the problems I also have when I

26:42

sleep sometimes is I I hear people say

26:45

you got to you can't eat like 3 or 4

26:47

hours before bed however I sometimes you

26:51

know I sometimes get home at 10:00 p.m.

26:53

and I get home hungry as hell at 10 p.m.

26:56

and then sometimes if I order food for

26:58

for example it might come at like 11:00

26:59

okay which means I end up eating at

27:01

11:00 and then I really see it in my

27:03

sleep schools

27:05

um I think as well that I'm someone that

27:08

tends to fall asleep later again this

27:10

might just be me telling BS to myself

27:12

but that's what tends to happen and I

27:13

know I'm not supposed to eat before bed

27:15

but I'm so hungry so is there anything

27:18

that I can eat before bed that won't

27:19

disrupt my sleep but will get rid of The

27:21

Hunger yes the preference is not to have

27:23

a huge meal right before bed that's

27:26

fried fatty um you know really heavy

27:29

sitting in your stomach that hour right

27:32

before bedtime um so if you're able to

27:34

time that and be strategic then that's

27:35

obviously the preference but I'm okay

27:37

with you having a pre-sleep snack a lot

27:39

of times for my athletes that means

27:41

we'll go for something like 50% of a

27:43

complex carb and like 50% of a lean

27:46

protein so for example cereal and milk

27:48

is an easy one cereal yes cereal and

27:51

milk of course we want something that's

27:53

whole grain uh and not you know

27:55

necessarily A sugary you know cereal but

27:58

Cal and milk is an easy one that's many

28:01

people have access to or cottage cheese

28:03

and fruit or 100% ho whe crackers and

28:06

peanut butter and the reason why is

28:08

because I don't want you waking up in

28:10

the middle of the night being hungry or

28:11

even trying to fall asleep and you feel

28:13

like you're hungry but we want something

28:14

that's slow digesting through the night

28:16

because ideally you're going to be

28:17

sleeping S 8 n hours during the night uh

28:21

and we want it to be able to get you to

28:23

the morning time and then you will fuel

28:25

when you wake up so a pre-sleep snack

28:27

can can be a great strategy if you're

28:29

coming home late and you want to

28:31

obviously be able to fuel before bed or

28:33

if you have a really early dinner and

28:35

you're hungry before bedtime yeah that

28:37

happens sometimes as well sometimes I'll

28:38

eat dinner at about 5:00 p.m. Y and then

28:41

I get to about 10 11:00 p.m. I'm still

28:43

awake and I'm starving okay so what's a

28:45

pre-sleep snack that you think you can

28:46

grab for some nuts okay yeah does that

28:49

work yeah yeah nuts have protein in them

28:52

um yeah you can grab a good nut mix

28:55

maybe you can partner that also with

28:56

like some yogurt too raspberries

28:59

raspberries yeah fruit yeah and some

29:02

yeah a a protein and carbon there and

29:05

those are good good pre-sleep snack

29:08

what's the if I wanted to destroy my

29:10

sleep what would you recommend I eat

29:12

right before bed what would you

29:14

recommend I I yeah consume right before

29:16

bed it can be if you just want to

29:17

destroy your entirely okay so we're

29:20

going to have the the night cap of

29:23

having a couple of drinks right before

29:25

bed okay so some alcohol yeah we'll have

29:27

some alcohol on board we'll we'll throw

29:29

in some caffeine too to to really get

29:32

you to stay awake in the next couple of

29:35

hours we add a really heavy meal that's

29:38

Fried Tomato based um fatty sitting in

29:42

your stomach right before bed and you

29:44

say tomato based yeah sometimes

29:46

individuals will have acid reflux with

29:49

tomato based products and so if that's

29:51

something that is is yeah is that

29:53

something that you experience then you

29:55

generally want to avoid some of the

29:57

Tomato based products that can aggravate

29:58

some of the acid reflux so some fried

30:02

food with some

30:04

ketchup yes okay so alcohol caffeine and

30:07

some fried food with some ketchup I

30:09

think that would really work to your

30:12

disadvantage during the nighttime any

30:14

sugar yes sugary carbs are tends to be

30:18

some of the preferences when you're

30:20

particularly also sleep deprived so

30:21

people will choose more carb heavy foods

30:25

and foods that have um less fiber and

30:28

more more sugar why fats is it that if I

30:32

eat those Foods before bed it impacts my

30:34

sleep what what what's going on I don't

30:37

think we have a great understanding of

30:39

that I think the field of sleep and

30:40

nutrition is definitely growing and I

30:43

think down the road in the next five or

30:44

10 years we hopefully we'll have more

30:46

answers to that but it's a fast area

30:48

that we do start to understand what we

30:50

eat can affect our sleep so for example

30:52

the stages of our sleep or how we sleep

30:55

during the night time some of the

30:57

smaller studies shown what you eat can

30:59

then affect having more Awakenings

31:01

during the nighttime um and affecting

31:03

the quality of your sleep but I think

31:05

many of them are still at the infancy

31:08

because that's certainly something I can

31:09

attest to I I talked about one time many

31:11

months ago I think it was last year

31:13

actually when I I was staying in a hotel

31:14

here in LA and I had a cookie before bed

31:17

because it was cuz I'm bloody you know I

31:19

blame the hotel I don't really blame the

31:20

hotel I take full responsibility it was

31:22

in the mini bar and I hadn't eaten all

31:24

day I'd came back I'd been working all

31:26

day and when I'm when when I'm when I've

31:28

been working a lot I'm much more likely

31:30

to reach for something bad and I had

31:32

this cookie and honestly I woke up the

31:33

next morning 8 hours later feeling like

31:35

I hadn't slept at all I just felt so

31:39

tired and I know it was that Bloody

31:41

cookie cuz I looked at my um my whoop

31:44

hashad investor and I could see that my

31:47

heart rate throughout the night was

31:48

really high like atypically high my

31:50

heart rate throughout the night will

31:51

usually just be this nice flat I don't

31:53

know 50 55 beats per minute and when I'd

31:56

had that cookie it it started and pretty

31:58

much stayed for the first 3 or 4 hours

32:00

about 75 beats so it was like my body

32:03

was was still on it was like I was

32:06

walking MH um and so I've always just

32:09

had this idea that when I if you eat

32:10

something like that right before bed

32:12

like puts your body under a lot of

32:14

strain like metabolic strain then it's

32:16

kind of like your body doesn't fall

32:19

asleep and my REM sleep's always

32:21

attacked as well if I if I if I were to

32:23

eat something like that yeah it's it's

32:25

very fascinating I think we're starting

32:27

to understand the connection of what we

32:30

eat how our gut is responding to that

32:32

and then how that potentially can affect

32:34

your sleep and then ultimately your

32:36

daytime functioning the next day but we

32:38

do recognize from sleep deprivation

32:40

studies uh that individuals will make

32:42

different nutritional choices and grab

32:44

for the cookies and the ice cream and

32:46

some of those other snacks later at

32:48

night than they would if they were well

32:51

rested that's a real horrible Paradox

32:53

isn't it it is do you know what I mean

32:56

like if you're tired then you're going

32:57

to eat bad things right before bed which

32:59

is going to make you sleep worse and

33:01

make you tired which is going to mean

33:03

you eat bad things before bed is vicious

33:05

cycle it is and unfortunately that could

33:07

potentially lead to potential weight

33:09

gain and other Downstream consequences

33:12

so just one other reason why obviously

33:15

making sure you're having sufficient

33:16

sleep but also having good practices and

33:19

your approach to sleep is also um a

33:22

priority so you're asking what else did

33:24

we do with Andre but in that ways of

33:28

preparing to sleep you know we addressed

33:30

does he have a windown routine so we

33:32

implemented one where he would read

33:35

before bed to actually relax and prepare

33:38

his brain and body to sleep for the

33:39

night managing a racing mind can be

33:42

incredibly common for not just the elate

33:44

athlete but for for all of us and so

33:47

even before he did that reading we'd

33:49

actually have him stretch and process

33:51

his thoughts outside of bed and that set

33:54

him up with a two-part system so that he

33:57

could actually be strategic about

33:59

preparing to sleep for the night a lot

34:02

of people can relate to this managing a

34:03

racing mind athletes um performers

34:07

creatives um so if I've got a racing

34:11

mind I think as well I think I tend to

34:13

feel like I have my best ideas just

34:15

before I'm about to get in bed what

34:17

would you recommend someone do if they

34:18

have a racing mind again incredibly

34:21

common to have racing thoughts thinking

34:24

through the day needing to process your

34:26

thoughts about how to prepare for

34:28

tomorrow so what I'd recommend is

34:30

spending 10 minutes processing your

34:33

thoughts outside of bed in dim light

34:36

every single night so that can mean I

34:39

would recommend you could do stretching

34:42

H you could do deep breathing exercises

34:44

to activate your parasympathetic system

34:46

and dampen down your sympathetic system

34:48

that's what I recommend for a lot of my

34:50

athletes if that's not your thing I

34:52

recommend journaling getting your

34:54

thoughts down onto paper uh or writing a

34:57

to-do list

34:58

those are easy ones that all of us can

35:00

do for even if you start with 5 minutes

35:02

today so I'm going to stretch um I've

35:05

read I read something I think it was

35:06

whoops data they released at the end of

35:08

the year where they because there's an

35:10

activity log in whoop where you

35:11

basically say what you're doing and I'm

35:13

going to butcher this but I think the

35:15

stats said that reading before bed

35:18

improved your sleep by about 5% across

35:21

everyone that was using ROP which makes

35:23

sense because you're going to be away

35:25

from Light I guess and you're also going

35:28

to be calming your you called it your

35:30

parasympathetic nervous system yes the

35:32

parasympathetic nervous system what do I

35:33

need to know about that in the context

35:35

of sleep that's just the system that

35:37

helps you relax and wind down the it is

35:41

in balance with the sympathetic system

35:43

which you may have heard is the fight or

35:44

flight system that gets you going that's

35:46

where your heartbe heartbeat will be

35:48

much more rapid your breathing can be

35:50

much more rapid when you need to go

35:52

that's when I'm overthinking yes but you

35:54

want to dampen that down and you want to

35:56

get your parasympathetic atic system

35:58

activated so you can help actually relax

36:00

physiologically your body and also your

36:02

brain so that you're in a better state

36:05

to sleep at night right it's easier to

36:09

slowly pump your brakes and then try to

36:12

sleep versus if you were going 60 M an

36:14

hour on a freeway and then suddenly

36:15

slamming on the brakes and just jumping

36:17

into bed so you actually have a process

36:20

to slow yourself down your brain and

36:22

body it will help prepare you to

36:24

actually get better sleep during the

36:26

night time just want to close off on

36:28

Andrew then is there anything else you

36:29

did with him to yes there's please give

36:31

me there's more that we've done with

36:33

Andre but this is to give you some

36:34

highlights so you know approaches to his

36:37

sleep were having that way to process

36:40

his thoughts being able to wind down

36:42

before bed and relax improving his sleep

36:46

environment so that it was as I

36:48

mentioned dark and cool I believe his

36:51

was around 67 degrees it was quiet um we

36:54

tried to we took out technology from his

36:57

bedroom so he didn't have that exposure

36:59

prior to bed we looked at cutting down

37:03

some of his power naps that were several

37:05

hours long to shorten them to 20 to 30

37:07

minutes and time it much closer to game

37:09

time so we would get that boost as you

37:11

would go into evening

37:13

games um and we looked at some of his

37:16

nutritional choices but this is the

37:18

highlight of of some of the ways that we

37:20

were strategic about his approach to

37:22

sleep and while we're also extending his

37:24

sleep from that under 7 to 7 and 1 12 to

37:27

8 hours because we knew he had an

37:29

accumulated sleep debt that had been

37:31

built from not getting sufficient sleep

37:33

probably for many months to years prior

37:35

to this and so as we've shared some of

37:39

the performance outcomes were

37:40

astonishing and he's been very vocal

37:42

about sharing his sleep story and he's

37:44

not the only one um if I could share

37:46

another story about another athlete

37:48

where you've asked what has saved

37:50

someone's career so with Andre I think

37:52

he saw this performance enhancement that

37:55

he could tap into that was that was um

37:58

previously he didn't know almost existed

38:01

right but then there's other athletes

38:02

where I think having sleep as a

38:05

foundation almost save their career one

38:08

example is Ryan Jensen so Ryan Jensen

38:10

was cut from the Ravens and put on the

38:12

practice squad and during this time as

38:15

the story goes his father said you know

38:18

what's happening you're not yourself you

38:19

like made your mom cry the other day you

38:22

know there there's something that's

38:23

going on and he eventually was tested

38:27

for sleep apnea which is a very very

38:30

common sleep disorder where your Airway

38:33

has some partial or full collapse during

38:35

the air during the night and so can have

38:36

very fragmented sleep through the night

38:40

and he was eventually tested diagnosed

38:43

and then put on treatment through what's

38:46

called a CPAP or continuous positive

38:48

airway pressure so it's a it's a mask

38:50

that provides air to keep the airway

38:53

open so then you actually can have

38:55

Consolidated sleep during the nighttime

38:58

and in a very neat way four years later

39:02

Ryan Jensen comes back signs a $42

39:05

million contract as one of the highest

39:08

paid centers in the NFL and then 3 years

39:11

later in

39:12

2021 wins the Super Bowl with Tom Brady

39:16

on the Bucks I see this as the success

39:18

story of Saving his career and he's been

39:20

vocal about how much of a difference it

39:23

made from literally almost the end of

39:25

his career happening to now being able

39:27

to succeed at the highest level and also

39:29

of course being healthier and being able

39:32

to have um more success on the field

39:34

than he probably imagined for himself

39:37

and better relationships presumably he's

39:39

not made his mother cry I'm quite

39:40

curious about that why is it that when

39:42

we haven't slept we're more likely to

39:44

make people cry because we are our

39:47

emotions are not regulated well when

39:50

we're short on sleep we are more

39:52

irritable we are more grouchy we respond

39:56

more with our emo

39:58

being able to um why we respond with our

40:01

emotions yeah what's going on in the

40:02

body is it like a different part of my

40:03

brain is it my hormones is it something

40:05

else it's probably a combination of both

40:08

right we know that um our emotional

40:10

regulation is not the same if we're well

40:12

rested versus if we're asleep deprived

40:15

and so we rely more on our innate

40:17

response which may not necessarily be

40:19

that which is strategic for what we

40:22

should be responding with if we were

40:24

tempered and had a better rest under our

40:26

belt um so we ask cognitively there's a

40:29

an implication of which part of your

40:31

brain you're going to be using but then

40:33

also you are just not in a state in

40:36

which you are going to be able to

40:38

respond in the way that you would

40:40

otherwise is it the amydala that's the

40:42

emotional center that is one that's

40:44

where like fear is very much um and

40:47

emotions and and um yeah the amydala is

40:50

where like fear and emotions are are

40:52

often centered because I've started when

40:53

I started learning more about sleep and

40:55

the impact it has on my emotions I could

40:56

see a huge VAR in how

41:00

um how I make my decisions but also how

41:03

like short I can be yeah if I haven't

41:06

slept yeah and so on the days now where

41:09

I haven't slept I literally have a

41:10

conversation with myself and tell myself

41:12

that I'm going to be in my M mdala today

41:14

so to try not to make any decisions try

41:16

not to talk to many people because

41:18

there's a risk that I might just be I

41:20

might be too short in how I consider

41:22

things and how I respond and I really

41:24

want to stay away from that but I've

41:26

seen such a huge huge variant and I've

41:27

also heard of other like famous CEOs and

41:29

stuff like that talk about how they they

41:33

focus so much on their sleep I can't was

41:35

reading something the other day and it

41:36

was I think it was it was Jeff Bezos do

41:40

you know what I'm gonna say I don't but

41:42

Jeff Bezos is someone who has been an

41:44

advocate about sleep and vocal that he

41:46

needs eight hours every night yes the

41:48

quote that I heard him say or someone

41:51

told me that he said was I think it

41:53

might have been Ariana Huffington

41:54

actually he said that his job as a CEO

41:59

is to make decisions and he says he

42:01

doesn't have to make that many decisions

42:02

a year he only makes a couple of big

42:04

decisions a year every day he's probably

42:06

just making two or three big decisions

42:08

so if his job is to make decisions then

42:11

his job is also to sleep because the

42:14

variance I see in even my own decision-

42:16

making when I'm slept and underslept is

42:17

just unbelievably staggering as someone

42:20

that sits here for seven eight hours a

42:22

day sometimes having

42:23

conversations you wouldn't believe the

42:25

difference when my brain and my mouth

42:27

are like connected because I've slept

42:29

it's like a different human being it's a

42:31

different podcast host um have you got

42:33

data to support this this impact on

42:35

cognitive performance yes so you

42:38

definitely make better decisions when

42:39

you're well rested you're less likely to

42:42

make cognitive errors you have better

42:45

judgment when you're well rested and

42:47

you're going to react faster so in the

42:49

situations where you need to make big

42:52

decisions whether it's on the field and

42:54

you need to react because you're running

42:56

a pass whe whether you are Jeff Bezos

42:58

and you're running a company and you

43:00

need to make critical decisions um under

43:03

under sometimes you know acute stressors

43:06

or you are someone who just is trying to

43:09

be your best we know that the cognitive

43:12

domain very much is influenced by

43:14

getting sufficient sleep and some of the

43:16

I would say you know large um very very

43:21

public disasters have happened as a

43:24

result of what we know is sleep loss um

43:27

where people have made poor decisions or

43:30

decisions that have led to unfortunate

43:32

disaster so for example the Challenger

43:34

disaster with a space shuttle that

43:37

exploded um and as a result there's

43:39

investigations of why did this happen

43:42

and the final report does suggest that

43:44

insufficient sleep for some of those key

43:47

decision makers around being able to

43:49

launch or not was attributed to fatigue

43:52

and insufficient sleep so being able to

43:53

make good Dame time decisions had this

43:56

disastrous effect ultimately on the

43:58

Challenger explosion or are you aware of

44:01

any studies that have measured cognitive

44:04

performance on and sleep yes so my

44:08

studies as well as many of my other

44:10

colleagues particularly look at reaction

44:12

time because we know reaction time is um

44:15

very finely or is very sensitive to

44:17

sleep loss and I'm starting to find it

44:19

also is sensitive to extension of sleep

44:22

so the other half of the story when you

44:24

pay back sleep sleep debt we see that

44:27

benefit on on uh reaction time but uh

44:31

reaction time and looking at aspects of

44:34

you know how quickly you're able to

44:36

respond or if you're having errors when

44:38

you're responding and you're not

44:39

supposed to be responding cognitively

44:42

those are um tests that are typically

44:44

used in a lot of sleep studies because

44:45

we know is quite sensitive can you give

44:47

me an example of a study that will

44:49

convince me that um if I sleep more my

44:52

cognitive performance will improve one

44:55

of the studies I mentioned before even

44:56

15 15 minutes more sleep was that

44:58

difference of that a student to the B

45:00

student there's another study I often

45:02

cite where if you look at the difference

45:04

of someone who gets 9 hours of sleep for

45:06

a full week the reaction time stays very

45:09

consistent great you want to react

45:11

appropriately you want to not make

45:13

cognitive errors or lapses in judgment

45:15

and that will be consistent over the

45:16

week if you're someone who's getting

45:18

seven hours of sleep you see a slowing

45:20

of that reaction time and then a

45:22

leveling off if you are getting 5 hours

45:24

of sleep you see an even sharper decline

45:27

in being able to react fast and then you

45:30

see a leveling off if you're getting

45:31

three hours of sleep every night you're

45:33

just going to tank that reaction time

45:35

and be slower at the same time you have

45:37

more lapses in judgment and not able to

45:40

respond appropriately but the the thing

45:43

about this study that I find so

45:44

fascinating is when we know that there's

45:47

this deficit when you're going to react

45:50

slower in the seven and the 5our group

45:53

there's this leveling off so people say

45:54

oh can I get used to getting

45:56

insufficiency sleep in some sense there

45:58

was this stabilizing of it but the

46:00

reality is you're not at your best right

46:02

we know what your reaction time could be

46:04

if you were getting that 9 hours and if

46:06

we even gave you three nights of what we

46:08

call recovery sleep so we said okay now

46:11

we get let's say 8 hours in bed for the

46:13

next 3 days you're going to feel better

46:15

and you'll probably feel more refreshed

46:17

but those reaction times for the 7 hours

46:20

and the 5 hours and the 3H hour group

46:23

didn't go back to the Baseline so it

46:25

takes more than one night night or one

46:27

weekend of that recovery sleep to get

46:31

you back to your Baseline and so that's

46:33

the bottom line that I tried to show my

46:35

athletes is that you can pay back sleep

46:38

debt but it often can take more than

46:40

just one day or one weekend of quality

46:44

sleep how long does it take so my

46:46

Studies have suggested multiple weeks uh

46:48

will really be beneficial to paying back

46:51

more of your sleep debt than just a

46:53

night or two nights of sleep the biggest

46:56

bankr tends to be in the first week or

46:58

two but obviously this depends on how

46:59

much more you're actually getting how

47:01

you're timing that in your night but the

47:04

bottom line is that if you can invest

47:06

maybe a week or maybe if you have a

47:08

vacation coming up and you do two weeks

47:10

that's going to be U the biggest impact

47:13

on paying back your sleep debt and if

47:15

you say hey that sounds like a long time

47:17

Dr ma well even potentially like 5 days

47:20

is one of my preliminary studies had

47:22

suggested in professional baseball

47:24

players even if it's 5 days of getting

47:26

one additional hour of sleep that was

47:29

shown to potential that was shown to

47:31

improve cognitive reaction time and also

47:34

processing speed in the athletes that

47:37

actually got one additional hour so if

47:38

you got six hours you went to seven if

47:40

you got seven hours you went to eight

47:42

hours versus the athletes that just

47:43

continue to get their normal sleep

47:46

interesting I I guess I've got to

47:47

understand what this concept or this

47:50

idea of sleep Deb is because I I want to

47:52

make sure I'm super clear on what it is

47:53

and isn't cuz when you say the word debt

47:55

I assume it's kind of like I I owe

47:57

the Sleep bank manager a couple of hours

48:00

um but but I I've kind of gone back on

48:03

forward on this idea of sleep debt I

48:05

think some people have told me that it's

48:06

real some people have told me that it's

48:07

not real um and I don't know where where

48:09

I should stand on it so if I if I

48:12

haven't so for example I flew into La

48:14

first couple of nights my sleep wasn't

48:15

great am I still but I had good sleep

48:18

last night am I still paying for it now

48:21

the way I explain the concept of sleep

48:22

dead is that your body requires a

48:24

certain amount every single night again

48:26

we talked but individual variability but

48:28

let's just say you need 8 hours every

48:31

night and conceptually if you don't meet

48:33

that 8 hours then you build up a debt so

48:35

if you're only getting six hours a night

48:36

you now have two hours of debt built up

48:38

if you go Monday to Friday that's 5 days

48:40

now you have 10 hours built

48:42

up right two hours every night becomes

48:45

10 hours and if you then sleep in on a

48:47

Saturday and you get let's just say 10

48:49

hours of sleep you've paid back two of

48:52

those hours but you still have eight

48:54

hours left to go and my buddy knows yes

48:57

so conceptually that's the idea of

48:59

accumulating sleep debt I do stand in

49:00

the camp that believes that that does

49:02

accumulate over time we do think that

49:05

you can pay back some of that debt on

49:07

the short term right so what you lost

49:10

like you said this past day or this past

49:12

week maybe this past month you should

49:14

pay that back with getting extra sleep

49:17

or we call Sleep extension we don't

49:19

think that you can Surplus and Bank more

49:24

and that you can pull from that in the

49:25

future but we re recognize that if

49:27

you've got insufficient sleep that if

49:30

you extend it over a couple of days

49:33

maybe a couple weeks then you will see

49:35

benefits in your reaction time in your

49:37

fatigue levels in your performance

49:39

outcomes and so we do recommend that as

49:41

a tool especially if you know that

49:44

you're going to have a day where you're

49:46

going to have sleep loss so it's a

49:49

strategy for example if you know okay in

49:51

a week I'm going to have a project and

49:54

I'm not going to be getting enough sleep

49:56

that night night then what you can do in

49:58

the days leading up to it is getting

50:00

sufficient sleep but arguably even more

50:03

so that we know when it gets to that

50:05

project the decrements that you'll

50:07

experience tend to be less robust than

50:09

if you went into it with just say that

50:11

was 5 hours so what evidence do you have

50:14

that sleep debt is a real thing what's

50:16

the first thing that comes to mind so my

50:19

my what I've dedicated my career to is

50:21

trying to understand how to pay back

50:23

sleep debt with sleep extension

50:25

interventions so what that means is

50:28

typically I'm working with a number of

50:29

Collegiate athletes where many of them

50:31

are not getting what they need because

50:33

when we start these studies many of them

50:35

have high fatigue levels they are

50:37

reacting slowly we often see lapses in

50:40

their um their judgment and their

50:43

ability to ultimately perform and

50:46

function which is what they consider

50:49

their Baseline but then when we actually

50:52

challenge them by paying back some of

50:54

that debt by getting additional hours

50:57

when we monitor the the differences that

50:59

can make over multiple weeks that's

51:01

where we see there's Improvement in the

51:03

reaction time their fatigue levels drop

51:07

their performance on the field improves

51:10

and so we recognize what has changed in

51:13

this is trying to pay back some of that

51:15

accumulated debt when the rest of their

51:18

training has been held consistent where

51:20

we've been trying to maintain the rest

51:22

of their their training which is key

51:24

which is the key point because in my

51:26

mind I go well maybe if you've got the

51:29

athlete to sleep well on that first

51:30

night then when they've showed up to

51:32

training they've trained a little bit

51:33

harder they've built their muscles a

51:35

little bit more they've had better

51:36

recovery in their muscles so

51:39

then the next day the same thing happens

51:41

because they've slept so it's actually

51:43

just that they're training better which

51:45

is causing them to improve their that's

51:46

fair we we've tried to hold their

51:48

training to be consistent and choosing

51:50

periods where their training isn't going

51:52

to vary significantly as well as you can

51:55

almost make the argument too that

51:56

sometimes as the season goes on athletes

51:59

get more fatigued more tired and that

52:02

can be actually a decrement to how

52:04

they'll perform so when we see the

52:05

benefits come down the road as the

52:07

season potentially gets even longer that

52:09

at least is some suggestion that the

52:11

intervention of sleep while we also have

52:13

the measures of how much more they were

52:16

getting actually were at least

52:18

associated with these performance

52:19

outcomes because REM one of the key

52:22

things about REM sleep which is the sort

52:23

of final stage of sleep is that it helps

52:25

with Muscle Recovery uh deep sleep is

52:28

actually deep sleep is where we uh deep

52:31

sleep is where it's implied that there's

52:33

more R Muscle Recovery regeneration

52:35

because there's the biggest pulse of

52:36

growth hormone during your deep sleep so

52:39

to back up a bit you have light stages

52:41

of sleep then you have deep stages of

52:43

sleep and then you have that rapid eye

52:45

movement sleep or when you dream that is

52:48

tends to be more associated with

52:50

consolidation of learning in memory and

52:53

skill consolidation so you go through

52:55

these Cycles during the night time about

52:57

90 to 120 minutes but the proportion

53:00

changes through the night the beginning

53:02

of the night you get more of that deep

53:04

sleep and then in the early morning

53:06

hours is when you get more of that REM

53:08

sleep so you might have woken up in an

53:10

earlier morning and had the recall of

53:12

these vivid dreams it's because you

53:14

often will be waking up from the that

53:16

REM sleep yes that happened last night

53:18

actually CU I woke up suspiciously early

53:20

for me so I woke up at about 5 or 6:00

53:23

and I was just kind of dipping in and

53:24

out of Dreams MH and were very vivid

53:27

dreams that I can still remember now

53:28

yeah um so the muscle memory element of

53:32

all of this what is muscle memory and

53:34

how is that sort of implicated with

53:36

sleep so muscle memory there's different

53:39

types of memory and you need sleep think

53:42

of sleep as hitting that save button

53:44

right you need to sleep after you have

53:47

learned new information learned a new

53:49

skill so that you can consolidate those

53:53

those uh those memories and be able to

53:55

retrieve it later so I always use an

53:58

analogy of hitting that save button

54:00

after you learn new material or learn a

54:02

new skill set you need to go home and

54:04

sleep so that it goes into long-term

54:05

storage and that you can retrieve that

54:07

the following day and subsequently

54:09

without that sleep we know that that

54:11

groundwork for that new skill or that

54:14

new memory is not going to be as strong

54:17

and so in the context of students who

54:20

are trying to study for a test or an

54:22

athlete that's trying to remember the

54:24

Playbook you want to space those

54:27

intervals that you're learning that

54:28

material and have sleep that follows so

54:31

that you strengthen those

54:34

connections and also you mentioned when

54:36

you were talking about one of your

54:37

athletes encouraging them to nap before

54:40

a game yes um I I read this fascinating

54:44

word in the research that I was doing on

54:46

your work I think it's napino yes what's

54:49

a napino the nappuccino so this is a

54:52

useful tool if you're trying to have a

54:55

temporary boost and aler and performance

54:57

so the nappuccino you go and take your

55:00

favorite caffeinated beverage the

55:02

caffeine will start to kick in in about

55:04

15 minutes and you go and then take your

55:07

20 to 30 minute power nap so if you're

55:10

able to fall asleep within that 5 to 10

55:12

minutes while the caffeine will start to

55:14

come on board then when you wake up

55:16

after 20 to 30 minutes then bam both the

55:18

caffeine will have kicked in and the

55:20

power naap will have kicked in and

55:22

there's research to show that that's

55:23

more effective for alertness and

55:26

performance Improvement for a couple of

55:28

hours than if you only did the caffeine

55:30

alone or only did the power nap alone so

55:33

the nappuccino is is a useful tool for

55:36

some who who utilize caffeine and you

55:39

can partner that together with a short

55:41

20 to 30 minute nap so if I wanted to

55:43

take a nap now I have an espresso and

55:47

then go and have my nap exactly yes the

55:50

cettas you do need to fall asleep within

55:52

about 10 minutes or else the caffeine

55:54

will start to come on board but if if

55:56

you do this in the late morning or early

55:58

afternoon it can be a helpful tool so

56:00

that you have a boost in your alertness

56:02

for a couple of hours and I grew up

56:05

thinking that naps didn't work because

56:07

the minute I learned about sleep and

56:08

these sleep cycles and that it takes I

56:10

don't know 45 60 Minutes whatever it is

56:12

to get into late stage sleep like the

56:14

Rems sleep the deep sleep I thought

56:16

what's the point taking a 15 20 minute

56:18

nap if I'm not going to get into deep or

56:20

REM sleep so there's benefit of just

56:22

that 15minute nap you mentioned you want

56:24

to stay in lighter stages of sleep cuz

56:26

there's benefits of lighter stages of

56:28

sleep and that can give you that

56:30

alertness and performance boost even

56:32

when you're in lighter stages of sleep

56:34

you actually don't want to go into

56:35

deeper stages of sleep because when you

56:37

take the longer naps as I think you you

56:40

might have shared you you've taken the

56:41

2-hour nap the three p you wake up and

56:43

you're much more sluggish much more

56:45

groggy that's not a good state for you

56:48

to go out and then do you know work

56:52

after that or it's not the state that

56:53

you want to be if you're a a basketball

56:55

player and have to go and play a game

56:58

but those deeper stages you come out of

57:00

what we call Sleep inertia with that

57:01

sluggishness and so it can also affect

57:04

your sleep at night and make it harder

57:06

to sleep subsequently so you actually

57:08

want to stay in those lighter stages of

57:10

sleep and keep those naps very short so

57:12

what's the maximum length that a nap

57:14

should be I like 30 minutes okay yes so

57:17

you can time that by setting an alarm if

57:20

it takes you 5 or 10 minutes to fall

57:22

asleep you can plan for that as well and

57:24

the setting alarm to wake yourself up 30

57:26

minutes later I think it's a great

57:28

strategy when again you don't get

57:30

sufficient sleep at night or you had

57:32

poor sleep leading into that night and

57:34

you need a little bit of a boost later

57:36

in the day what do you think of the

57:37

snooze button the snooze button I'm not

57:41

a huge fan of the snooze um I fully

57:44

understand why people love to hit the

57:45

snooze and then go back to bed uh and if

57:48

you're someone who does that one of my

57:50

suggestions is just to cut down so that

57:52

you only hit the snooze once 5 minutes

57:54

later start your day the reason why is

57:57

because it helps to maximize your rem or

58:00

your dreaming sleep in those early

58:01

morning hours if you can actually sleep

58:04

Consolidated all the way until the time

58:05

you have to wake up so for example if

58:07

you're someone who hits the snooze

58:09

button five times every five minutes for

58:12

a half hour it means that you're having

58:14

very interrupted sleep for the last half

58:17

hour of your night versus if you just

58:20

let yourself sleep Consolidated all the

58:22

way through and then maybe hit the

58:24

snooze button just one time and then got

58:26

yourself up to start your day it means

58:28

you would have given yourself another 25

58:31

minutes of Consolidated sleep likely

58:33

that dreaming REM sleep that's so

58:35

important for learning and memory and so

58:38

that is one just easy adjustment that

58:40

you can make in terms of your morning

58:43

approach to maximizing what you get

58:45

during the night so what's the what's

58:46

the value in consolidating it versus

58:48

just having fragmented sleep yeah so

58:51

then if you're getting a lot of that REM

58:53

sleep in those early morning hours and

58:55

you're snoozing you're going to be

58:57

waking up and coming out of that REM

58:59

sleep so you likely are changing the

59:01

stages of sleep you would be getting in

59:03

those early hours so you would then be

59:05

awake and then probably going into

59:07

lighter stages of sleep awake lighter

59:09

stages of sleep than necessarily having

59:11

a solid REM period all the way until you

59:14

wake up what's the cost of that so

59:16

learning a memory and consolidation is

59:19

definitely one area that we recognize is

59:22

associated with that REM sleep and so

59:24

you want as we talked about it changes

59:26

through the night you want to have as

59:27

much as possible but you part have to

59:30

have just the duration so when you get

59:32

the most of it in the morning hours if

59:34

you cut that short and either wake up

59:36

earlier or you're snoozing and you're

59:38

interrupting it you're not going to

59:40

maximize the value you get of the hours

59:43

in rem okay so I just want to make sure

59:45

that I those 25 minutes I give them to

59:48

REM sleep versus just giving them to

59:51

little fragmented light sleep exactly so

59:54

I'm better off just putting my alarm to

59:57

the time that I actually have to get out

59:58

of bed exactly just to maximize the

59:59

amount of R sleep that I get to

60:01

consolidate my memories are you a

60:02

snoozer no not really okay well I mean

60:06

we all have our moments but not really I

60:09

can't remember the last time I pressed

60:10

pressed the snooze button but the thing

60:12

that I do and I'm not sure if this is a

60:13

good idea or not is because I have told

60:17

myself and I say told myself because I'm

60:18

quite conscious of the BS that I believe

60:20

about myself but um I've told myself

60:23

that I'm like an alow chronotype or

60:24

something which by the way I don't even

60:26

know if it's true and I don't know if

60:27

chronotypes are true um and I typically

60:31

work quite late and I love working late

60:33

I get better ideas late I do my writing

60:35

pretty late at night as well and so what

60:37

I've done in my life is I've basically

60:39

made sure that I don't have any meetings

60:40

or any engagements before 11:00 so even

60:44

like this podcast today started at 11:00

60:46

yes um basically nothing in my life

60:48

starts till 11:00 for that very reason

60:51

just to because if I do end up staying

60:53

up a little bit late I want to be able

60:54

to kind of sleep through without having

60:56

to set an alarm and just wake up

60:57

naturally what do you think of that is

60:59

that suboptimal no I think it's a great

61:02

strategy so there are chronotypes where

61:05

you've mentioned you're more of an

61:06

evening owl you go to bed later you like

61:08

to wake up later as a natural

61:10

predilection is is that real or I just

61:12

myself this is justifying myself no

61:15

there is a natural tendency for some to

61:17

feel like they are evening owls and

61:19

there's others who feel like they do

61:21

much better in the morning so they go to

61:22

bed earlier they wake up earlier they're

61:24

more productive in the morning those are

61:25

are morning Larks and then there is a

61:28

group that's somewhere in the middle

61:29

that don't strongly lean one way or

61:31

another but really what you're doing is

61:33

you're you're making your sleep work to

61:35

your your chronotype and to your

61:37

advantage where you do feel like you're

61:39

more productive in the evenings and then

61:41

you want to be able to maximize your

61:42

sleep waking up without an alarm and

61:44

starting your day later I think that's

61:46

like a great strategy because a lot of

61:47

people aren't able to have that

61:50

flexibility and so Society often will

61:52

force particularly the night owls onto

61:55

an earlier schedule where you have to

61:57

wake up whether to go to work or other

61:59

obligations or kids earlier Point yeah

62:03

and and then you're cutting your sleep

62:05

short like you mentioned like with

62:07

school and then we're getting these um

62:10

and then you're on a schedule that

62:12

doesn't work synergistically with what

62:14

your chronotype is they should do some

62:16

studies on kids in school and like

62:18

Disobedience and ability to pay

62:20

attention and do homework in grades

62:22

because honestly I was so useless in

62:24

school and I really I really think of it

62:26

now I'm not entirely sure here because I

62:29

got diagnosed with ADHD when I was like

62:30

30 years old so part of me thinks I've

62:31

just got like a very active brain and

62:34

part part of having an active brain

62:35

meant that late at night I was Finding

62:36

ways to stimulate it by playing Video

62:38

Games Etc so that might just be the

62:40

reason but the other reason might be

62:41

that I'm an Al Chron type and I found it

62:43

really hard to get up at like 7:30 to

62:46

get to go to school by sort of 8:30ish

62:50

and so I would miss school I would show

62:52

up knacked I would sleep in lessons um

62:56

and I feel like school just starts way

62:58

too early for kids it's a ongoing uh

63:01

it's an ongoing problem and actually in

63:03

a very interesting way there has been a

63:06

change to school start times

63:07

particularly in California um this this

63:10

year was the first year that school

63:12

start start times for high schools and

63:14

for middle schools was shifted much

63:16

later because there are studies to show

63:18

that our when our students are better

63:20

rested they have higher attendance rates

63:22

their GPA and grades are much higher

63:24

there's less mental health issues um

63:27

there's less car accidents and so this

63:29

these Studies have um been over the last

63:32

decade and longer in which they have

63:34

built evidence to help make decisions to

63:38

start school time later um and that is

63:42

in California been enacted this year and

63:44

some other states are starting to follow

63:46

suit but to your point what makes it

63:48

challenging is that at the age of high

63:51

school many of those body clocks are

63:53

shifted and so students St want to an

63:56

adolescence go to bed later and wake up

63:59

later naturally that's just how our

64:00

sleep changes through the life cycle but

64:03

when they stay up late and then we cut

64:05

their sleep short by forcing them to get

64:06

up really early for school now they have

64:09

insufficient sleep and that builds like

64:11

a sleep debt and so they're not setting

64:13

themselves up for success in school for

64:15

learning and memory so that's where

64:16

again there's more evidence of if we can

64:18

shift the school start time get these

64:20

students to have a little bit more sleep

64:22

they ultimately are better prepared for

64:25

school come to school have less uh car

64:28

accidents and are just healthier

64:30

students do you think there's anything

64:31

parents need to know about sleep when it

64:34

as it relates to their children and

64:36

sleep hygiene with their children I

64:38

think it's important for parents to

64:40

start at the early early years of

64:43

instilling good sleep habits a good

64:45

sleep routine and giving their their

64:48

children the tools and skills to be able

64:52

to make sure that it's a priority as

64:54

they go through early childhood into

64:56

adolescence and hopefully then sets

64:58

themselves up for making sure it's a

65:00

priority for their adult life um I'm a

65:03

young parent myself I just had uh my

65:05

first son and so um I recognize and can

65:08

empathize with the TR the struggles of

65:11

getting sufficient sleep when they're

65:12

very young but then trying to instill

65:15

how they can approach their sleep from

65:17

early age I think would be incredibly

65:19

helpful to also just change culturally

65:20

how we think about sleep because so many

65:23

of us now have never learned about sleep

65:25

for or what we should do until you're an

65:27

adult but if we can make that change

65:29

earlier on I think we're going to have

65:31

healthier kids better families um who

65:34

are better rested and and also just this

65:37

generation where we recognize this is so

65:39

important that we shouldn't sacrifice it

65:41

because we're doing ourselves a

65:42

disservice to letting us be the best

65:45

that we can possibly be how old is your

65:47

son 11 months 11 months so how are you

65:49

sleeping oh I transparently am quite

65:52

tired okay I I as a yeah new Young mom

65:56

also um I don't have the ideal sleep

65:58

that I know I would love um it's a for a

66:02

short time but I'm trying to be

66:03

strategic of the things that I can do

66:06

with some of the tools that we've talked

66:08

about trying to leverage power naps um

66:10

when for example I do have to still wake

66:12

up during the night time to tend to him

66:14

um and you know the early morning starts

66:16

are not always consistent so my sleep

66:19

schedule is not always consistent so you

66:21

know going back to those three buckets

66:24

we talked about earlier like if I don't

66:26

get the full duration that I want then

66:28

how do I maximize the quality right I've

66:30

optimized my sleep environment I try to

66:32

have a process to wind down at nighttime

66:35

um or the timing you know is and the

66:37

sleep schedule is another area that you

66:39

can still work on when for example you

66:41

may not be getting the duration um so

66:44

these are strategies that I try to

66:45

employ when I know that I um also am a

66:48

work in progress and trying to get the

66:50

best sleep possible Once Upon a Time if

66:52

you had a business idea it was

66:54

exceptionally difficult to get going but

66:57

now in the age of Shopify it is

67:01

exceptionally easy as many of you will

67:03

know Shopify are a sponsor of this

67:05

podcast if you don't know Shopify it's

67:07

an exceptionally simple web platform for

67:09

anybody that's got an idea that wants to

67:11

transact on a global scale so things

67:14

like these conversation cards which we

67:15

sell we've sold using Shopify and it

67:18

only took us a couple of clicks to get

67:21

going so why did we choose Shopify for a

67:23

number of reasons but I think one of the

67:24

big ones which goes and appreciated is

67:26

their checkout system converts 36%

67:28

better compared to other platforms and

67:31

here's what I'm going to do to remove

67:33

the cost for you if you go to

67:34

shopify.com Bartlet you'll be able to

67:37

try Shopify for

67:39

$1 a month I've seen Shopify completely

67:43

change people's lives and for many of

67:45

you I think it could change yours what

67:47

are the other examples of sort of case

67:50

studies that you're you're most proud of

67:52

or that were most pivotal in shaping

67:53

your thinking about sleep I mentioned

67:56

the Philadelphia Eagles back in 2017 and

67:59

tried to help them educate their players

68:02

about sleep how to have a more strategic

68:04

approach to their wind down routine to

68:07

thinking about how they're integrating

68:09

sleep into their training practices and

68:12

thinking about ultimately how they

68:14

travel and and having for example

68:16

strategies to minimize jet lag when

68:18

you're Crossing time zones and having to

68:20

play in different locations than the

68:22

give me some of those then so some the

68:24

tips you'd give me someone that travels

68:26

a lot yeah um pre- during and post

68:28

travel yeah what should I be thinking

68:30

about before I travel while I'm

68:31

traveling and after I I land yes so have

68:34

a a game plan for every trip I think

68:37

most people have no strategies in place

68:38

when they travel they just get onto an

68:40

airplane get to a new location and try

68:42

to adjust when they get there that is

68:44

not really a great strategy you want to

68:46

have at least a pre-flight strategy

68:48

inflight strategy and post-flight

68:50

strategies because that will set

68:51

yourself up better to minimize jet lag

68:54

also travel fatigue and ultimately then

68:57

be able to acclimate faster if you're

68:59

Crossing multiple time zones before

69:01

pre-flight try not to panic pack I know

69:03

all of us do do Panic packing right

69:06

before bed right before we're getting on

69:07

a flight um so you want to try and be

69:10

strategic and pack early you want to get

69:12

at least why do I want to not panic pack

69:14

because most people will Panic pack the

69:16

night before they they have a flight and

69:17

then they'll cut their sleep short so

69:19

they'll get only say 5 hours of sleep

69:21

because they're staying up late trying

69:22

to pack everything and get ready for

69:24

that early morning flight or for the

69:26

next day well I I pack the morning of

69:28

travel so okay but I'm I'm out here in

69:31

La for I'm out here for 2 weeks and I

69:33

packed a carryon carryon suitcase okay

69:36

cuz I so look at what I'm wearing I wear

69:38

just the same outfit every day so I have

69:39

like the same outfit um but I pack

69:42

literally an hour before I go to the

69:43

airport okay okay so but you're right it

69:45

does cut my sleep because I could have

69:47

been in bed whether it's beginning of

69:49

the day or the end of the day if it's

69:51

affecting then the duration of your

69:53

sleep I would recommend trying to a

69:55

little more strategic and do it a day

69:57

before two days before don't pain it

69:59

pack number two try to get at least

70:02

those seven hours if not

70:04

your your amount of sleep that makes you

70:07

feel like you're functioning and

70:08

Performing well um at least a day if not

70:11

two days if you get insufficient sleep

70:13

before you get onto an airplane jet lag

70:15

will be worse and that travel fatigue

70:17

can feel much more robust and you're

70:20

more likely to have the quas on in the

70:21

airport which is going to destroy the

70:23

whole thing for for you so those are

70:26

things that you can do before flight

70:27

depending on where you're going you can

70:29

actually start to adjust your body clock

70:31

before you even get onto the airplane so

70:33

let's just take a 3-hour time difference

70:36

here in the US if you're in the west

70:38

coast and you're going to the east coast

70:39

three time zones you can actually start

70:41

to go to bed a half hour early wake up a

70:45

half hour early do that for two or 3

70:48

days and and get sunlight in the morning

70:51

because that sunlight reinforces to your

70:53

brain to start to shift that body clock

70:56

so if you can do that a day before 2

70:58

days before maybe 3 days before when you

71:00

actually get to the new location you

71:01

don't have to shift your body clock

71:03

three time zones you've already shifted

71:05

it one time zone or two time zones

71:08

because the rule of thumb is for every

71:09

time zone you cross it takes about a day

71:12

to re acclimate even if you feel better

71:14

after the first day usually jetti feels

71:17

the worst in that first day when you

71:18

arrive um but physiologically you

71:21

haven't really adjusted fully even if

71:24

it's over you know a couple of days so

71:26

that's the rule of thumb so those are

71:27

some things pre-flight you can do when

71:29

you're in Flight you want to hydrate

71:32

throughout the flight because

71:33

dehydration can worsen jet lag you want

71:35

to think about getting onto the new time

71:37

zone schedule so again depending on

71:40

which direction you're flying and how

71:41

many times when you're Crossing you want

71:43

to start to synchronize perhaps like

71:45

when you're actually sleeping or some of

71:47

your meal times so that you're getting

71:48

onto that schedule and then you partner

71:51

that with for example building a travel

71:53

sleep kit I'm a huge fan of investing in

71:55

sleep tools that will help you sleep

71:58

when you need to in non- ideal

71:59

situations whether you're on the plane

72:01

and now trying to take a nap or shift

72:03

your sleep schedule then you actually

72:05

have an eye mask and ear plugs you have

72:07

noise cancelling headphones you have

72:09

your own travel pillow you have the

72:12

tools with you to S drugs sorry sleeping

72:15

medication okay so some uh medications

72:18

can be helpful like melatonin

72:21

particularly if you're trying to advance

72:22

your clock has um evidence that it can

72:25

help shift that a little bit more

72:26

quickly when you're trying to advance

72:28

your clock earlier would you recommend

72:30

it to athletes um it I would say if it's

72:33

something that you've used before and

72:35

you know that you don't experience some

72:37

of the side effects it could be a useful

72:39

tool so melatonin while it's one of the

72:41

most commonly used supplements and sleep

72:43

aids there are still side effects that

72:45

to be wary of so specifically for

72:47

athletes too you can feel more groggy

72:49

and sluggish when you wake up from it um

72:51

it's not regulated by the the FDA here

72:55

in the US and so you don't always know

72:57

what's actually in those supplements so

72:59

for my lead athletes they use what's

73:01

called NSF Sports certified versions um

73:04

they're just there's more um regulation

73:06

around them but in for the for the you

73:09

know everyday person you know there's a

73:11

study where they looked at the amount of

73:13

melatone that was actually in a variety

73:15

of these supplements and it was a wide

73:17

range from over 400% of what was on the

73:20

label to obviously sub you know you know

73:23

uh under 100% of what they actually

73:25

indicated so there's a wide range of

73:27

what's actually going to be in the

73:28

supplement but it can help particularly

73:31

when you're on travel with um re

73:34

acclimating my team here we most of them

73:36

use a certain app when we travel and it

73:39

just tells you basically you say where

73:41

you're going and then it'll tell you

73:42

what time to eat what time not to eat

73:45

Etc so you can get aligned with that

73:47

with your destinations like circadian

73:49

rhythm I guess so we'll link below one

73:51

of the apps that our team use we're not

73:53

affiliated with them in any way but

73:55

we're flying out here I know will and my

73:56

team sent me a screenshot and said Steve

73:57

this is what time you need to be eating

73:59

and everything cuz we're going to La so

74:01

it's been super helpful for all of us I

74:03

I'll link that below because I know some

74:04

people are going to be wondering what

74:05

apps they should be using so we're in

74:07

the flight we've got our postt trvel

74:09

flight kit with the ey masks and all

74:11

those kinds of things in we've got our

74:13

app is we're

74:15

hydrated um noise cancelling headphones

74:18

is there anything else we need to be

74:19

thinking about while we're traveling

74:20

when you're traveling so on a plane on a

74:23

plane so we talked about hydration minim

74:26

Al and caffeine or eliminating entirely

74:28

is a straty inad of having on board

74:33

because that can also potentially worsen

74:36

um jet lag and or make it more difficult

74:38

to sleep when you're actually trying to

74:40

when you arrive and again seeking light

74:43

that is the most powerful signal to your

74:45

brain to help shift your body clock also

74:48

bringing sunglasses so that you actually

74:50

avoid sunlight at certain times because

74:52

your body can respond differently

74:55

depending again on your home location

74:57

and how many time zones youve crossed so

74:58

there's certain times that these apps

75:00

can be helpful that will likely tell you

75:02

you don't want to get sunlight during

75:04

these hours and so you want to be

75:06

strategic about that and just make sure

75:07

you have sunglasses so that you can

75:09

still go about your day but trying to

75:11

minimize that sun exposure um getting

75:14

well rested and getting sufficient sleep

75:16

even if it might be a little bit more

75:18

fragmented than usual just giving

75:19

yourself at least a day to acclimate so

75:22

that I would recommend not scheduling

75:23

your most important meetings right when

75:25

you get in or in that first day for

75:27

athletes they don't want to do maximal

75:30

exercise because there's a risk that

75:32

that jetl could increase injury in that

75:35

acute period so you want your body clock

75:37

to be able to readjust and then using

75:39

caffeine and power nap strategically so

75:42

for example our afternoon 1 to 4:00 is

75:45

typically when we have this dip in our

75:47

alertness now when you get to a new time

75:49

zone that can occur at a different time

75:51

point in the day but strategically then

75:54

you can use CA and and uh Power naaps to

75:57

be able to help you through those lulls

75:59

when you're in that new time zone what

76:02

about sex sleep and sex in bed and that

76:05

is it because I think so many people

76:07

actually make the mistake of being in

76:10

bed and being on their computer on their

76:12

phone doing other work while they're

76:14

awake and that actually helps strengthen

76:16

that connection that when you're in bed

76:18

you're awake and your brain will start

76:19

to associate that so sleep and sex are

76:22

all that you want in bed everything else

76:24

should be outside so when we talked

76:25

about that wind down routine or that

76:27

racing mind all that should happen

76:29

outside of bed because you want to

76:30

actually tease apart that Association

76:33

that your brain is making of being awake

76:35

in bed and that will be one small

76:37

adjustment that's helpful to to get

76:39

better rest at night but will will sex

76:41

improve or hurt my sleep I'm thinking

76:45

you know CU I'm really trying to get out

76:47

like should you be in bed with someone

76:48

does it does it improve your sleep to

76:50

sleep with someone and does sex have an

76:52

impact on your sleep cuz I you know

76:55

speaking from personal experience I

76:57

think that if I have sex before bed I

76:58

sleep better I don't think that there's

77:01

great literature on sleep and sex out

77:03

there but um I will say that there has

77:05

been um there's definitely an impact

77:08

potentially of a bed partner sleeping

77:10

with you in bed because their movements

77:12

can affect your sleep if they snore that

77:14

can very much affect your waking up

77:17

during the night time um and then you

77:20

know with sex I think that that is

77:21

something anecdotally some people will

77:23

definitely say it helps them to be able

77:25

to consolidate their sleep and they feel

77:26

like the quality is better um but I

77:29

don't think there's a lot of great

77:30

studies that are are being funded for

77:32

research right now what is the most

77:35

popular question you typically get asked

77:36

about sleep from people most popular

77:39

question is napping which we've

77:40

discussed keep them short 20 to 30

77:42

minutes I I get asked a fair amount

77:45

about can you oversleep so no we don't

77:48

think you really you should you can

77:49

overs sleep when some people say they

77:52

get say 9 hours or 10 hours and feel

77:55

much more groggy it's because often

77:57

they've shifted their sleep schedule or

77:59

they have an accumulated debt that say

78:01

built up and then they're finally

78:02

allowing their body to relax and so now

78:04

that they're they're they don't have the

78:06

mask of stimulating activities from

78:09

their day or their work that can read I

78:11

read I didn't read a study one of my

78:12

podcast guests told me that there is a

78:15

harm to oversleeping but I think from

78:17

what I managed to

78:18

ascertain the studies they were citing

78:22

just proved that people who sleep for

78:23

like 10 or 11 hours

78:25

typically have a higher risk of um

78:27

disease and mental health but then it's

78:29

hard to establish cause and effect

78:31

because if you're in bed for 11 hours

78:33

maybe you're a depressed and B one would

78:35

assume you're exercising and moving a

78:37

little bit less so you probably got a

78:38

lot of like cardiovascular issues yes so

78:41

there are studies of looking at the more

78:43

extremes of Less hours of sleep and then

78:45

even more hours of sleep like the 10

78:47

hours and obviously there can be other

78:49

comorbid conditions uh that go along

78:52

with individuals like who sleep much

78:54

longer you mentioned you can sleep much

78:56

longer because of depression or other um

78:59

chronic health issues and so um that's a

79:01

different context of thinking about

79:02

oversleeping I think in the question I

79:04

typically get is oh I slept one night of

79:06

10 hours and I feel worse so I'm never

79:08

going to do that again and that's

79:10

actually not true right I think we want

79:12

to have just more consistent hours that

79:14

are timed so you're not having a shift

79:16

in the bedtime and wake Time by like

79:18

three hours later um because that could

79:20

be why you're having that grogginess

79:21

when you wake up not because you got the

79:23

10 hours but because you're waking up up

79:24

now at 11:00 a.m. instead of your

79:27

typical you know 8:00 a.m. wake up time

79:29

um you could be more dehydrated because

79:31

of that longer time um snoring is one

79:34

that I get asked a fair amount about is

79:37

you know is it completely benign and I

79:39

would say if you're snoring you should

79:41

go talk with your primary care doctor

79:43

and you should potentially ask about

79:45

getting a sleep study there is Sleep

79:48

Disorders like obstructive sleep apnea

79:50

we mentioned before that's incredibly

79:52

common and that's when that Airway has

79:54

partial or full collapse and can lead to

79:56

very fragmented sleep so you can wake up

79:58

not refreshed because you really didn't

80:00

get quality sleep during the night time

80:02

and snoring I think in our society has

80:04

become just an accepted Norm that can

80:06

happen as you get older but that is not

80:08

always the case that it is uh a benign a

80:12

benign symptom and so um making sure

80:14

that you talk to your primary care

80:16

doctor and potentially get a sleep study

80:18

I think is incredibly important is sleep

80:21

apnea the the most common um disease

80:24

disorder you see yes yes it

80:27

isapa can be incredibly common I believe

80:30

it's about 26% of people of people in

80:33

the ages of 30 to 70 and so that as you

80:35

imagine that's like one in four

80:37

individuals but many individuals don't

80:40

actually get tested or diagnosed and

80:43

then treated until they're way into

80:45

their adulthood or even pasted into

80:48

their 6070s so with asleep apnea often

80:51

times people will not wake up refreshed

80:53

they will often feel tired in the

80:56

daytime they may have a lot of caffeine

80:59

or have to rely on power kns to keep

81:01

their alertness up a lot of individuals

81:04

will have early morning Awakenings so in

81:06

those 3 4 5:00 in the morning they'll

81:08

wake up and not realize why they're

81:09

waking up frequently snoring can be very

81:12

common if you've ever had a bed partner

81:14

or a roommate and they've ever noted

81:16

that you stop breathing or pause

81:18

breathing or gasp and choke those are

81:22

very suggestive that you might have

81:24

sleep apnea um and again it is

81:27

incredibly common but very manageable so

81:29

something that I would highly recommend

81:31

if you your bed partner your your

81:35

roommate snore just uh suggest to have

81:38

um I would suggest they go see their

81:40

primary care doctor and typically is it

81:43

people that are slightly overweight that

81:45

are more likely and susceptible to

81:46

having sleep apnea yes yes a lot of

81:49

individuals who are overweight or obese

81:52

um will be more at risk for Sleep back

81:54

as you imagine the collapse of the

81:56

airway typically is here around the neck

81:58

and so more weight um typically is is

82:01

not helpful for for apne but you can

82:03

also be a very fit healthy young

82:06

individual so I work with Elite athletes

82:08

and I have a number of my professional

82:10

athletes who again are young healthy

82:13

males but their Anatomy is just more

82:16

susceptible for this condition what are

82:18

the um the big rebuttal you get the big

82:21

excuses that you hear from people I

82:23

don't have enough time

82:25

yeah I don't have enough time to sleep

82:26

okay I don't have enough time to sleep

82:28

and what do you think of that one uh I

82:30

don't think that that's true I think we

82:32

we all are going to make sacrifices and

82:36

priorities in our day and I think if you

82:39

are saying you don't have enough time I

82:41

think there's ways to be strategic about

82:43

how you manage your time in the day I

82:45

think we all have five minutes to

82:47

implement a windown routine we can all

82:49

do that at the very least I think all of

82:52

us can um optim ize our environment I

82:56

think we all can invest in some sleep

82:57

tools I think we can make better choices

83:00

about how you go about your day so you

83:02

set yourself up better for sleep so I

83:04

think that those are just small

83:05

adjustments but will be huge in terms of

83:08

what that will mean at night um I hear

83:11

that you know I will sleep you know I'll

83:13

sleep in the offseason right now in

83:16

season is when I want to focus on being

83:17

my best but really I think that's the a

83:20

backwards way of thinking about it if

83:22

you're thinking about optimizing your

83:24

sleep when it gets to the season or the

83:26

postseason when some of the most

83:27

important games come down the line

83:29

you're just playing catchup because if

83:31

you have a sleep that built up and

83:33

you're just trying to maintain that

83:34

through the season you actually are at a

83:36

deficit versus the other guy or growl on

83:40

the team who has paid that back in the

83:42

off seon now you have given yourself you

83:46

know zero sleep debt you're at your best

83:48

and now you're just trying to maintain

83:50

that through the

83:51

season what about injury what if I if

83:55

I'm an athlete and I'm underslept are

83:57

there any studies that suggest I'm more

83:59

prone to injury there are a few studies

84:01

that do suggest getting insufficient

84:03

sleep so under 6 hours there's been more

84:06

fatigue related injuries in adolescent

84:08

athletes there's also a study that has

84:11

looked at under eight hours of sleep

84:13

still has a increased risk around 1.7

84:15

fold higher of inj fold 170% yes yeah of

84:21

higher risk of injury when you're

84:23

getting under 8 hours of sleep versus

84:25

those that got more than 8 hours of

84:27

sleep and so I think it's unclear

84:29

exactly why you're specifically more at

84:33

risk for injury but I tried to take a

84:36

look at the biomechanical changes of

84:39

what happens when athletes are not

84:41

getting sufficient sleep in one of my

84:43

early studies um that has explored the

84:48

biomechanical changes and what we showed

84:50

is that when you're not getting

84:51

sufficient sleep for multiple days you

84:53

have more more variability in your

84:57

biomechanics yeah so you're moving

84:59

differently so you're not actually

85:00

selecting probably your preferred

85:03

coordination strategy so for example I

85:05

had them doing a vertical jump and if

85:07

you're well rested you likely should be

85:09

able to do that very consistently as an

85:11

elite athlete but when you're not well

85:14

rested it's much more variable so

85:15

they're moving differently and that may

85:17

put people at risk for injury they like

85:20

Landing differently a little bit jumping

85:22

yeah how their knees their hips um are

85:24

coordinated together differs and so that

85:27

may put you at risk for injury down the

85:29

road but more to come hopefully on that

85:31

front there's just not that many studies

85:33

that currently exist I've noticed

85:36

something recently because recently I've

85:38

had to get up quite early on a few occas

85:40

so when I say early I mean I've had to

85:43

go get wake up at 4:00 a.m. because I've

85:45

got a flight at 6:00 a.m. and really

85:47

interestingly if I so say if I go in bed

85:50

at like 11:00 p.m. at night and I and I

85:52

have to wake up at say 3:00 or 4:00 a.m.

85:54

when I wake up at 3:00 or 4 a.m. I'm

85:56

really hungry but if I wake up at 8:00

85:59

a.m. M I'm not hungry well you are

86:02

starting your day much earlier so your

86:04

body clock is starting at a much earlier

86:06

time than you typically would versus

86:08

8:00 so you almost have what we call

86:10

socially jetlagged yourself right where

86:13

you didn't get on an airplane yet but

86:15

you literally shifted your whole sleep

86:17

schedule to be an earlier wakeup time

86:20

and so you can feel some of the symptoms

86:21

of jet lag where you can have and you

86:24

can have stomach GI upset you can feel

86:26

more fatigued you can have those

86:28

symptoms as if you gotone onto a new

86:30

time zone and flew there but you hadn't

86:33

yet if it it almost feels dare I say

86:37

like hormonal like it because I was

86:39

trying to understand what hunger is and

86:41

hunger is essentially a bunch of

86:42

hormones isn't it so yes you have

86:44

certain hormones that regulate your

86:46

appetite so leptin and gin are two

86:48

hormones that impact your appetite um

86:52

gin makes you more hungry leptin feels

86:55

more satiated if you don't get

86:57

sufficient sleep these levels can be

86:59

imbalanced and so that's where people

87:02

tend to as we've talked about grav

87:04

gravitate towards you know carb and

87:07

unhealthy Foods in the later evening

87:08

time um but also when these are not well

87:11

balanced that can also lead to weight

87:13

gain or situations where you're not able

87:16

to potentially um regulate your weight

87:18

appropriately and so when I have

87:19

individuals who are wondering about not

87:22

making weight goals I ask them about

87:24

their sleep and they don't recognize

87:25

that sometimes being able to address how

87:27

they sleep will actually help them to

87:29

get to the weight management goals that

87:30

they're really striving for Jack what

87:33

about you we've talked about sleep

87:34

before how how are you sleeping at the

87:35

moment I've got pretty good at my sleep

87:38

but waking up in the middle of the night

87:40

you spoke about it in terms of like

87:41

sleep happena but it feels like it

87:43

should be normal to wake up so

87:46

Awakenings actually can be very normal

87:49

this is a very common question I get

87:50

asked is you know should I never wake up

87:52

at night and that's actually not true so

87:54

you shouldn't necessarily hit your head

87:56

on the pillow and then you're out for

87:58

the full night and then never have an

87:59

Awakening if you wake up you go to the

88:01

bathroom one time you come back fall

88:03

asleep in the 5 to 10 minutes great

88:05

that's actually very normal um so you

88:09

can have Awakenings that happen at even

88:12

in the early morning hours and that can

88:14

be just a typical part of your sleep

88:16

cycle because it can be as your

88:17

transitioning between these sleep stages

88:19

that you'll have these Awakenings

88:21

sometimes you'll consciously know that

88:22

you're awake and other times you will

88:25

unconsciously awaken um and so something

88:27

like a wereable might actually show you

88:29

that you have these Awakenings during

88:30

the night time that you don't recall um

88:33

but when it becomes very frequent then

88:35

you have these Awakenings and over

88:37

multiple weeks or it makes it more

88:40

difficult and challenging than to

88:41

function in the daytime that's when we

88:42

get more concerned about Awakenings

88:44

because there's a number of ways reasons

88:47

why you can awaken at nighttime um to

88:49

name a few it could be environmental

88:51

factors that affect your sleep it could

88:53

be that you had alcohol you know that

88:55

right before bedtime maybe there's

88:57

caffeine that's causing you to be awake

88:59

there's also just stress or if you just

89:01

have a racing mind that potentially

89:03

could cuse those Awakenings a bed

89:05

partner is something that is a common

89:07

culprit um or underlying sleep apnea

89:10

that can happen and so there's early

89:12

Awakenings that need to be investigated

89:14

with your doctor how much does um

89:16

alcohol impact my sleep in percentage

89:18

times I I don't know the specific

89:20

statistics of how that's going to impact

89:23

um um the the duration but I will say

89:26

that when we look at the studies of

89:28

moderate to high consumption of alcohol

89:30

that very much has a association with

89:33

more fragmented sleep more Awakenings

89:35

during the night time and so the quality

89:37

of your sleep is significantly impaired

89:40

so if you're trying to um have an

89:42

important meeting the following day an

89:44

important game or you're just trying to

89:47

be able to be your best that following

89:49

day at least try to minimize or

89:51

eliminate the alcohol or in the sleep in

89:53

the sleep docks world we say drink when

89:55

you wake up we'd rather you have that

89:57

alcohol in the morning or the or the

90:00

early afternoon not not necessarily

90:02

right before bed and so um yeah that's

90:05

that's one of the strategies is to

90:06

eliminate the alcohol right before

90:08

sleeping Dr M we have a closing

90:11

tradition on this podcast where the last

90:12

guest leaves a question for the next

90:13

guest not knowing who they're going to

90:14

leave it for and the question that has

90:16

been left for you is if you could go

90:21

back and fix your worst mistake but it

90:24

would change everything afterwards with

90:27

no

90:28

guarantees would you do

90:32

it no I would not do it I think we make

90:36

mistakes in life and we learn from them

90:39

and we adapt and we it can set us off in

90:43

a different direction but that

90:45

ultimately is going to influence who we

90:47

become who we interact with how we build

90:50

a life forward and I wouldn't change my

90:53

life life if I could go back and it

90:56

could would set me on a completely

90:58

different trajectory could you think of

90:59

a worst mistake when I said that did one

91:01

come to mind or was that a category of

91:03

there wasn't I maybe I haven't spent a

91:06

lot of time to try and dive into some of

91:09

my worst mistakes I definitely have made

91:10

mistakes along the way and uh obviously

91:13

would have done some things differently

91:15

in my personal or professional life but

91:17

I do think that that is what has made me

91:20

who I am today right I think I have

91:21

tried to learn from those mistakes

91:24

try not to make them again um and try to

91:27

figure out how to adapt from there but

91:29

that has I think set me on a path that

91:31

uh is where I am today so I wouldn't I

91:33

wouldn't change that it's so interesting

91:36

the subject of sleep for me because I I

91:38

was part of the like burnout Brigade The

91:41

like badge of honor burnout Brigade for

91:43

a long period of time and I I definitely

91:45

thought in my early career when I

91:47

started my first business around 18 19

91:49

20 21 up until probably about I'm going

91:52

to say up until about 26

91:54

I thought that me not sleeping was

91:57

something to show off and I thought that

91:59

I was more impressive if I communicated

92:02

to people how little I slept and how

92:04

much I was able to accomplish in spite

92:06

of that I think actually the greatest en

92:08

enabler to my productivity is like being

92:10

really obsessive about my sleep and

92:12

having that rule that I said where

92:14

nothing in my life unless there's a

92:16

something that's immovable is booked

92:17

before 11 o00 and I really hope other

92:19

people um after listening to you after

92:24

going through your work which is all

92:25

available online really prioritize their

92:28

sleep because as you've shown through

92:29

your research and the studies the the

92:32

impact the very real impact on our lives

92:35

is so profound maybe one shift in your

92:38

mindset too that I encourage you but

92:40

everyone that's listening as well is the

92:43

way I frame it to athletes is it's a

92:45

small tweak but if you think about sleep

92:48

is not the end of today it's the

92:50

beginning of tomorrow what you do to

92:53

prepare

92:54

what you do to try and get the the

92:55

duration that you're striving for and

92:57

how you set yourself up will affect

93:00

everything about how you function how

93:03

you interact with individuals and

93:05

ultimately perform tomorrow if you're

93:07

willing to do everything it takes for

93:09

you to be your best sleep has to be

93:13

foundational in every day and if you're

93:16

willing to put in that time and that

93:18

effort you'll reap the benefits that

93:19

come down the line and it can be

93:21

completely

93:22

lifechanging but you have to give

93:24

yourself that Grace and that patience to

93:27

be able to make these small adjustments

93:30

but as some of my athletes have shown it

93:32

can be a GameChanger for them it can

93:34

completely change the trajectory of

93:36

their career and even life once they

93:39

actually get quality sleep under their

93:41

belt and so I challenge everyone to make

93:44

small adjustments starting tonight and

93:47

reach out if you have questions but

93:49

where do we find you uh you can reach me

was speaking to um some of the guys at

94:15

Manchester United um two weeks ago in a

94:18

hotel about from the well-being team

94:20

about these subjects and the sort of um

94:22

interconnected subjects of sleep and

94:24

well-being generally but also I've

94:25

spoken to people at Chelsea Football

94:27

Club that listen to the podcast about

94:32

and aspiring athletes and just people

94:34

like me who are going to benefit

94:35

profoundly from the work that you do and

94:37

the research that you've you've done

94:39

importance of sleep which is often

94:41

misunderstood and is seen as a

94:42

negotiable part of our lives so thank

94:44

you so much for the work that you do and

94:46

I'm very excited to see um where your

No Doubt thank you so much thanks for

94:55

having me it's been a

94:56

pleasure perfect Ted has quite frankly

94:59

taken the nation by storm a small green

95:02

energy drink that you've probably seen

95:04

popping up through a Tesco or to a

95:05

waitrose they've grown by almost

95:09

10,000% in a very short period of time

95:13

because people are sick and tired of the

95:15

typical unhealthy energy drinks and

95:17

they've been looking for an alternative

95:19

perfect Ted is the drink that I drink as

95:21

I'm sat here doing the podcast because

95:23

it gives me increased focus it doesn't

95:26

give me crashes which sometimes might

95:27

happen if I'm having a three four five

95:29

six hour conversation with someone on

95:31

the podcast and it tastes amazing it's

95:33

exactly what I've been looking for in

95:35

terms of energy that's why I'm an

95:37

investor and that's why they sponsor

95:38
