The Woman Who Helps NBA Stars To Sleep: Stop Having Showers Just Before Bed! Dr Cheri Mah
2553 segments
I was 86% correct on accurately
predicting when an NBA team will be at
highest risk of losing strictly based on
the sleep oh gosh yes and just 15 or 30
minutes can make a difference so let's
dive into just some very practical
strategies to get the best sleep
possible Dr sharim ma is a renowned
sleep doctor and performance expert
whose sleep optimization research has
enhanced the careers of CEOs as well as
athletes in the NFL MLB and Formula 1
and has provided lifechanging expertise
to companies like under aror and Google
for my Elite athletes that I work with
sufficient sleep it's a game Cher for
example we saw 12% faster Reaction Time
a 9% Improvement in free throws and a 4%
increase in Faster Sprint time and when
you experience what it feels like to be
well rested you never want to go back
getting insufficient sleep and it
doesn't have to be these big jumps I'd
love to dig into that okay so i' have a
shower then I get straight into bed
after is that good or bad tweak the
timing of your shower and your hot bath
to just an hour or two before bed it's
hard to grasp how much of a difference
this can make in your life what about
sex does it have an impact on your sleep
okay so is there anything that I can eat
before bed that won't disrupt my sleep
but will get rid of The Hunger there's a
pre-sleep meal for example cereal and
milk cereal and the reason why is
because and then I read this fascinating
word nappuccino yes this is a useful
tool if you're a working professional
and you need a little boost and
alertness and performance what you do is
the DI of AO raffle is about to close

Dr M what is it you do and why is it so
important in your mind that you do
it great question so I am a sleep
physician um but I spend a lot of my
time and career trying to educate and
and advocate for people to prioritize
sleep right this fascinating process
that each of us does every single night
and arguably is about a third of our
lives but many individuals don't do this
very well or they you know sacrifice it
and overlook this area I very much
believe if you don't sleep your best you
will not be your best or counter to that
is if you your if your sleep is best
you'll be at your best and what that
means if I unpack that a little bit more
is we often are sacrificing our sleep
we're underslept we often don't have
good quality sleep it we're very
reactive to our sleep at night time and
it's the last thing that we think of at
the end of the day when we wrap
everything up um and that's arguably not
going to put ourselves up to be the best
we can be in the following day right and
for my Elite athletes that I work with
when you actually get sufficient sleep
you have practices that you plan into
your day and you actually are more
proactive with that it can be a game
Cher and for them when it comes to
performance on the field that can be the
difference of a 9% Improvement in free
throw shots it can mean reacting 12%
faster and so until you experience that
it sometimes is hard to grasp how much
of a difference this can make in your
life but it is one of the foundations
that will impact everything about how
you function your mood how you feel and
ultimately perform the following day if
I could offer you or yes you
specifically see if I could offer you
something that's free and healthy and
safe that's going to help you think more
clearly make better decisions be in a
better mood be more productive and
efficient would you want it of course
how much exactly and so it's really a
decision of whether you want to invest
uh your time to be able to be more
proactive with this particular area of
your life to get the benefits that come
down the road with it who do you work
with give me a sort of broad spectrum of
the individuals organizations that
you've worked with on sleep and why have
they come to you I've had an opportunity
to work with a number of professional
sports teams and athletes as well as
organizations over the years to try and
apply the science into practice to help
them improve their sleep their
scheduling and their travel so for
example I've been with the San Francisco
Giants in Major League Baseball I've
worked with um NBA teams like the Golden
State Warriors uh NFL teams like the
Philadelphia Eagles I won a Super Bowl
ring in 2017 with them to um other
sports organizations like Nike and under
arour and ESPN to try and show how you
can predict when NBA teams will lose
strictly based on the schedule and
insufficient sleep opportunities um to
individual athletes who recognize you
know hey this is an area that I am not
optimizing and I know this can be such a
valuable asset to extend my career to
prevent injuries down the road and to
help me be at my best do you ever work
with CEOs I do I do work with Executives
and seite um um Executives to try and
help them be their best because they too
are high performers right their
performance outcomes are maybe a little
bit different than pro athletes where
we're quantifying on field performance
and looking at their swim times and what
they're doing when it comes to the you
know onc court or on field um
performance outcomes but for these
Executives they arguably are also making
incredibly important decisions they have
to still react when they're under
pressure and they have to make good
judgment calls and so many of the things
that I coach and and try to recommend to
my lead athletes are very much
applicable to the SE Suite executive or
even just the working professional
that's really what what I found so
fascinating about your research and your
work is that although there's a focus on
athletes as someone who is also
traveling is also very very busy also um
struggles with sleep sometimes because
I'm I have to perform late at night
whether that's on stage or with meetings
or whatever it might be I resonated with
so much of it and I also train in the
gym pretty much every day if I can um
and I've also noticed a correlation
between things like injury in the gym
based on how I'm sleeping in my quote
unquote sleep de but I but I I want to
confront two things the first thing I
want to confront is the misconceptions
around sleep that you encounter over and
over again what are the like big
overarching misconceptions that stand in
the way of people believing in and
implementing the advice that you give
them I'll start with just this badge of
honor that I really believe still
persists in society where you should get
only four or five hours of sleep and
should be able to perform at your best
and I think the tides are turning and I
do think that that is changing over the
last several years where there are more
vocal Advocates of um you know Elite
athletes like the Tom Brady who you know
say everything is around performance
enhancement I going need to go to to bed
early so that I can wake up early and to
be ready to go for the day to you know
the Simone bios who says I need to get 8
hours of sleep and so I think that that
is a badge of honor that is now shifting
and now it's going to become well if
you're not getting your 8 n 10 hours of
sleep right then you're actually at a
decrement to yourself and you're
actually not going to set yourself up to
be the best that you could possibly be
whether you're on the field as a pro
athlete or whether you're leading an
organization or trying to go after
whatever ever it is that matters to you
right and and I think that's going to
continue to shift but I'm excited about
it because that's one thing until you
experience that that difference and that
life transformation of what it feels
like to be well rested then it can be a
game changer you never want to go back
to it again when you're getting
insufficient sleep are there any
misconceptions around how to sleep in
sleep hygiene and um I know the
quantities of sleep weeny that also seem
to stand in people's way
of them getting a great night's sleep
yeah so I think that there is a
misconception that everyone needs a
certain amount of sleep there's
individual variability so the the
recommendation from the American Academy
of sleep medicine and the Sleep research
Society so two of our national
organizations here in the US recommend
minimally 7 hours of sleep but that's
the lower threshold you might actually
need 8 hours or 9 hours or more to feel
well rested right I I personally feel
terrible on seven hours and I much more
need the eight to nine hours and there's
those in that individual differences so
you need to find what you feel well
rested you're able to function well at a
high level during the day and that will
then be your individual requirement so I
think there's this misperception that
everyone needs a certain amount but you
need to find what works for you and it's
all about small changes so if you're not
at 7 hours I think you shared sometimes
you're you're you're under that oh yeah
sometimes yeah you know it's about F 15
or 30 minutes more can make a difference
refence so if you're getting 6 hours
then I'm going to recommend getting 15
minutes or 30 minutes more every day for
this one week and then get 15 or 30
minutes more next week so that you're
building from say 6 hours of sleep to 6
and a half hours and you may not think
that that's that much but we can all do
15 minutes more right we're less
scrolling or doing what we're wrapping
up our day but those 15 minutes add up
where that's a difference of like an a
student to a b student or 11 minutes
more sleep is the difference of a b
student to a c student in one of these
studies really exactly and then over the
course of a week 15 minutes will be
almost 2 hours more sleep than if you
didn't what was the study so this was a
study done um in high school students
but looking at the difference of how
much they're sleeping versus their
correlation to to grades and so that
15minute difference was shown to be that
A to B student 11 minutes from that B to
C student oh gosh yes so it doesn't have
to be these big jumps
but small changes over time will will
add up the the study I have in front of
me here which I've printed out um also
highlights the importance of sleep for
everybody but also specifically in this
case for athletes can you walk me
through this study and what you found in
this particular study on the adult male
basketball players yes and how you
conducted the study so in the study we
looked at the men's basketball team and
we really tried to examine if we
extended their sleep over 5 to 7 weeks
encouraging them to get 9 or 10 hours of
sleep every single night to B pay back
what we call an accumulated sleep debt
would we see any impact on performance
outcome specifically would we see an
impact on reaction time their fatigue
levels and would we see an impact on
their onc Court performance specifically
free throw shots three-point shots
Sprint time and these are measures that
we would do after every regular practice
and over the course of those 5 to 7
weeks we demonstrated that we saw a 9%
Improvement in free throws a 9%
Improvement in three-point shots we saw
a 12% faster reaction time and a 4%
increase in uh faster Sprint time and so
these were the quantification which was
novel at the time was what was quite
fascinating because it wasn't that 1%
that I think many Elite athletes are
trying to find every small way to adjust
their training to get that 1% better
better because in Elite Sport that 1%
can be the difference right of being at
the top versus not but this was arguably
9% or even double digits for Reaction
Time depending on the outcome and so
we've expanded that looking at other
sports as well but this was one of the
first ones to show that it really
potentially could have a significant
impact on performance outcome for these
athletes how much did they sleep more
per night to get those results yeah so
they did so we did quantify objectively
through a uh what's called actigraphy it
looks like a wearable nowadays um and
then compar that also with what they
thought they were getting and so we did
extend their sleep um uh substantially
over I believe an hour and a half uh
compared to what they were getting prior
to the study because getting 9% more
free throws or three-point shots or 12%
better reaction time is quite frankly
for some teams the difference between
like winning a championship and not yeah
because I think about the Premier League
often which is it's soccer I guess
football um often time there's been
leagues within my lifetime there's been
years in my lifetime where both teams
have um tied with the same amount of
points and one is one just on the amount
of goals they've scored they've just
scored a couple more goals so after 38
games they both have the exact same
points and the winner is just the person
that scored like a couple more goals but
even you think of reaction times you
think of goalkeepers in in soccer their
whole game is reaction time so if you
can increase your reaction time by 12%
it's really really staggering
it can be a game changer and I think
that's what has been so fascinating with
some of the athletes or organizations
and teams I've worked with who have made
it to the most important games and those
championships because the hope is that
you've invested not just the night
before that championship game but you've
invested an entire season even starting
in the off season on cultivating better
habits to give yourself that foundation
and be able to leverage these strategies
that the other team is not because we
know that it significantly can impact
not just the individual level on
performance outcome but organizations as
a whole and I think one example of that
is um I partnered with ESPN to do what
was called the NBA schedule alert
project where they ask can you predict
Dr ma when NBA teams are going to be at
risk of losing games strictly based on
the schedule so not factoring in
strength of team but based simply on
their schedule where they're traveling
to how many times are crossing these
various factors does it affect
organizations as a whole and teams and
their game outcomes as you mentioned and
over three seasons I was 76 to 86%
correct on accurately predicting when an
NBA team will be at highest risk of
losing strictly based on the schedule so
in the spirit of the project we didn't
factor in strength of team but to me
that was staggering because there's many
other factors that maybe are not always
considered to be as clearly important
about you know this travel schedule up
front but hey maybe these factors really
do play and influence um game outcomes
in this way and that's not the only
thing that has obviously shown that
organizations and teams as a as a whole
will have differences performance
outcome there's other studies like the
Monday Night Football study that showed
if you simply bet on a West Coast team
when they play an East Coast West Coast
matchup during night games over 25
seasons you'd beat the Las Vegas point
spread 68% of the time and so if you're
able to predict with with greater
accuracy then obviously there is
potentially some gambling outcomes that
could work in your favor here but really
being able to show that you would be
able to benefit and predict better than
what the spread will be between the the
two teams over is that because the West
sorry the West Coast team has gone which
who's who's traveled it doesn't matter
it simply matters that the West Coast
team is playing the east Coast team
during night games so this can happen on
the west coast it can happen on the East
Coast the reason why is because
performance is enhanced in the late
afternoon to evening around 4: to 8:00
in both scenarios the body clock of the
West Coast team because they typically
go out just the day before the game it
feels like they're on the west coast
okay right so when you're a West Coast
team and you stay there and the East
Coast team comes out the East Coast is
three hours later so what is a seven
o'clock game on a West Coast feels like
a 10 o'clock game for a East Coast team
got you same thing applies when the West
Coast team goes east coast even if it's
a 7:00 game there yeah the West Coast
feels like it's a 4:00 body clock yes
and so that special window of around 4:
to 8:00 p.m. when world records are
broken and performance in a 24-hour day
is is optimal and that is leveraged then
over those 25 Seasons that the West
Coast will have more favorable outcome
overall got you so in this study you did
in 2011 that was published in 2011 one
of the things I read as well is that
players who had slept more in your study
sprinted
faster I mean quite quite dramatically
faster as well I I think from 16.2
seconds at the start of the study versus
15.5 seconds at the end yes over what
distance was that yes so that was from
the Baseline to half court to Baseline
to full court and back so we chose a
very standardized
sprinting uh sprinting drill that they
are familiar with that we could
replicate after every regular practice
as you imagine not everyone on the team
was participating on in this study and
so they did this after every regular
practice and that ended up being a 4%
difference in Sprint time that is pretty
crazy do do do professional teams know
this do athletes know this are they
aware of this or is this something
that's fairly new some are aware and I
think the momentum is shifting towards
more athletes more teams recognizing
that this is an untapped competitive
advantage that this is an area that they
may or may not have implemented specific
strategies or education or or planning
for when they travel but I think the
more Forward Thinking organizations
teams and athletes are starting to pick
this up and starting to recognize that
they can use this as a weapon right as a
performance-enhancing drug if you may
because it is safe it's healthy it's
effective and we know that it will be
one of the only things that can give you
these performance benefits um and and
those are the ones that are trying to
Leverage The Science into application
for optimizing yeah their sleep at
nighttime have you seen athletes
individual athletes change and save
their careers when I say change I mean
change the trajectory of their career or
save their careers because they focused
on their sleep and can you give me some
examples of that yes Golden State
Warriors Andre Iguodala he's someone who
I worked closely with he came to the
Warriors back in around 2014 he was
already an Allstar he was 28 at the time
knew that his career was going to
probably be sunsetting at some future
time but wanted to extend it as long as
possible but he knew he wasn't doing
sleep best as possible he was very open
about sharing how he would stay up till
the we hours in the morning playing
video games would sleep for a few hours
go to practice play for a few hours come
home and take a 2 to three hour power
nap and that was his routine for for 10
years um and he said you know how do I
improve how I approach my sleep I know
that this is important as an athlete to
who wants to play in the league as long
as possible so I had the opportunity to
work with him over several months to
help him recraft how he approached to
sleep including a wind down routine
thought about some of his nutritional
choices tried to shorten his naps time
them closer to game time to give him the
Boost and alertness and performance be
able to manage a racing mind and be able
to have just a more proactive approach
to his sleep in a really neat way The
Following Season the Warriors went to
the championship for the first time in
many years they won he came back with
the finals MVP he subsequently has won
three more championships with them so
four in total and extended his career
for 10 years when we made these changes
there was a quantification of the
performance enhancement so a third party
Quantified as he went from under seven
to seven and a half to more than eight
hours he had a two-fold increase in his
threo percentage he had a
88.9% increase in his free throw shots
which very interestingly is the exact
same 9% that I showed in my man's
basketball study that had the same 9%
Improvement in free throws he had a 29%
Improvement in his points per minute a
45% decrease in his fowls and so you
know these numbers are pretty staggering
again for someone who's already at the
highest level as an Allstar and it's not
to take anything away from Andre but he
has been very vocal about the difference
this made as he changed these habits it
he says it changed everything for him
and I think that that's you know a very
inspiring story of what it can mean to
extend your career and be able to almost
tap into this additional performance
capacity that I think even he was
surprised about that he for the first
time was able to improve beyond what he
already thought was his best and I think
that's what's so inspiring because this
is something that's accessible to all of
us to be able to tap into that little
bit more so not only did he win the most
valuable player award but his
three-point conversion went up
218% yes so during the time that I had
worked with him his three-o percentage
went up twofold during that time it begs
the question what did you do to
him and you know you named a couple of
things there but I'd love to dig into
some of those key points sure um where
you started with him the specific sort
of implement things that you implemented
into his um sleep hygiene and so that if
I am him the day that you met him when
he was taking those naps and staying up
late which I often do to be fair um
where would you start with me and where
did you start with him okay so let's
dive into is just some very practical
strategies that I started to challenge
him with which was we'll start with his
sleep environment we want to make your
sleep environment like a cave really
dark quiet cool and
comfortable dark cave so dark blackout
curtains eye mask are some of the
easiest tools that you can grab but are
incredibly helpful and great investment
to be able to use that both at home and
then when you travel so that if you're
in a non-ideal environment like a hotel
room you have for example an IM mask
that can help dampen out the the light
uh making it quiet so
earplugs uh also a white noise machine
I'm a huge fan of even a small travel
white noise so that you can actually
mask over external noises that you may
or not be able to control I'm someone
that tells myself that I sleep with
something playing for I grew up with a
radio in my room so when I'm as an adult
now I'm always looking to play something
as I fall asleep is that going to hurt
my Sleep Quality I would say if you're
accustomed to this would say that's fine
to continue to do so I am not a fan of
having the TV on and having the bright
light exposed um to you in that hour
before bedtime because it also can just
be very psychologically stimulating but
if like you said it's a radio or it's a
podcast that you feel is helping you
relax then I'm a fan of it do you think
Daria will help people relax it
might it might help you at least think
about your sleep a bit more and
challenge you to do maybe one one change
tonight we consider that to be a
scientific endorsement of of the podcast
um okay so I've got sound down you are a
fan of the white white noise machines I
am because sometimes there's external
noises like a garbage truck or
construction that you're not always able
to control so if you can at least mask
over it temporarily that can sometimes
be helpful to keep individuals more
asleep during the night time and there's
even some now that are adaptive so if
the door slams then the volume
temporarily increases and then will
decrease so there's almost these smart
white noise machine that are that are
coming out on the market so that's from
a noise standpoint and earplugs are
going to be helpful if you're traveling
when you're at home you can obviously
use those to dampen down any external
noise from a from a temperature
standpoint you want it to be cool I
think this is an area that a lot of
people can benefit from because they
often sleep in much warmer temperatures
than what we know is probably more
conducive to sleep which is cooler 60 to
67° has been shown to help individuals
stay asleep and fall asleep that may be
frigidly cold for some but you have to
find the temperature that's right for
you I would say decrease your
temperature by say one degree or two
degrees every couple of days and then
you can find the temperature that works
well for you and there's even technology
now where there's mattress covers that
can help you regulate temperature from
much cooler to warmer so if there's
differences in bed Partners that's a way
that you can actually accommodate both
of their preferences so that's about 16
to 20° cus
what about when I shower or I bath
because often I go and have a shower
then I get straight into bed after yes
is that good or bad I would encourage
you to shift that timing a little bit
earlier into the night so an hour and a
half before you are planning to go to
bed I would shift your shower because
when you are taking a hot bath or hot
shower it increases your core
temperature but when you fall asleep
your core temperature drops so you don't
want that competing signal to be right
before bedtime but if you back that
shower up an hour and a half that should
be sufficient time that we think
potentially there's an augmentation of
helping that drop in temperature and
some smaller Studies have shown that
that can help decrease the time to fall
asleep and also enhance deep sleep which
has implications for Muscle Recovery
regeneration and you get more of that in
the earlier part of your night so it's
an easy fix uh just to tweak the timing
of your shower in your hot bath to be
just an hour or two before bedtime not
right before bed so it's a strategy too
if you have difficulties winding down
and relaxing to implement that hot
shower hot bath earlier in the evening
one of the problems I also have when I
sleep sometimes is I I hear people say
you got to you can't eat like 3 or 4
hours before bed however I sometimes you
know I sometimes get home at 10:00 p.m.
and I get home hungry as hell at 10 p.m.
and then sometimes if I order food for
for example it might come at like 11:00
okay which means I end up eating at
11:00 and then I really see it in my
sleep schools
um I think as well that I'm someone that
tends to fall asleep later again this
might just be me telling BS to myself
but that's what tends to happen and I
know I'm not supposed to eat before bed
but I'm so hungry so is there anything
that I can eat before bed that won't
disrupt my sleep but will get rid of The
Hunger yes the preference is not to have
a huge meal right before bed that's
fried fatty um you know really heavy
sitting in your stomach that hour right
before bedtime um so if you're able to
time that and be strategic then that's
obviously the preference but I'm okay
with you having a pre-sleep snack a lot
of times for my athletes that means
we'll go for something like 50% of a
complex carb and like 50% of a lean
protein so for example cereal and milk
is an easy one cereal yes cereal and
milk of course we want something that's
whole grain uh and not you know
necessarily A sugary you know cereal but
Cal and milk is an easy one that's many
people have access to or cottage cheese
and fruit or 100% ho whe crackers and
peanut butter and the reason why is
because I don't want you waking up in
the middle of the night being hungry or
even trying to fall asleep and you feel
like you're hungry but we want something
that's slow digesting through the night
because ideally you're going to be
sleeping S 8 n hours during the night uh
and we want it to be able to get you to
the morning time and then you will fuel
when you wake up so a pre-sleep snack
can can be a great strategy if you're
coming home late and you want to
obviously be able to fuel before bed or
if you have a really early dinner and
you're hungry before bedtime yeah that
happens sometimes as well sometimes I'll
eat dinner at about 5:00 p.m. Y and then
I get to about 10 11:00 p.m. I'm still
awake and I'm starving okay so what's a
pre-sleep snack that you think you can
grab for some nuts okay yeah does that
work yeah yeah nuts have protein in them
um yeah you can grab a good nut mix
maybe you can partner that also with
like some yogurt too raspberries
raspberries yeah fruit yeah and some
yeah a a protein and carbon there and
those are good good pre-sleep snack
what's the if I wanted to destroy my
sleep what would you recommend I eat
right before bed what would you
recommend I I yeah consume right before
bed it can be if you just want to
destroy your entirely okay so we're
going to have the the night cap of
having a couple of drinks right before
bed okay so some alcohol yeah we'll have
some alcohol on board we'll we'll throw
in some caffeine too to to really get
you to stay awake in the next couple of
hours we add a really heavy meal that's
Fried Tomato based um fatty sitting in
your stomach right before bed and you
say tomato based yeah sometimes
individuals will have acid reflux with
tomato based products and so if that's
something that is is yeah is that
something that you experience then you
generally want to avoid some of the
Tomato based products that can aggravate
some of the acid reflux so some fried
food with some
ketchup yes okay so alcohol caffeine and
some fried food with some ketchup I
think that would really work to your
disadvantage during the nighttime any
sugar yes sugary carbs are tends to be
some of the preferences when you're
particularly also sleep deprived so
people will choose more carb heavy foods
and foods that have um less fiber and
more more sugar why fats is it that if I
eat those Foods before bed it impacts my
sleep what what what's going on I don't
think we have a great understanding of
that I think the field of sleep and
nutrition is definitely growing and I
think down the road in the next five or
10 years we hopefully we'll have more
answers to that but it's a fast area
that we do start to understand what we
eat can affect our sleep so for example
the stages of our sleep or how we sleep
during the night time some of the
smaller studies shown what you eat can
then affect having more Awakenings
during the nighttime um and affecting
the quality of your sleep but I think
many of them are still at the infancy
because that's certainly something I can
attest to I I talked about one time many
months ago I think it was last year
actually when I I was staying in a hotel
here in LA and I had a cookie before bed
because it was cuz I'm bloody you know I
blame the hotel I don't really blame the
hotel I take full responsibility it was
in the mini bar and I hadn't eaten all
day I'd came back I'd been working all
day and when I'm when when I'm when I've
been working a lot I'm much more likely
to reach for something bad and I had
this cookie and honestly I woke up the
next morning 8 hours later feeling like
I hadn't slept at all I just felt so
tired and I know it was that Bloody
cookie cuz I looked at my um my whoop
hashad investor and I could see that my
heart rate throughout the night was
really high like atypically high my
heart rate throughout the night will
usually just be this nice flat I don't
know 50 55 beats per minute and when I'd
had that cookie it it started and pretty
much stayed for the first 3 or 4 hours
about 75 beats so it was like my body
was was still on it was like I was
walking MH um and so I've always just
had this idea that when I if you eat
something like that right before bed
like puts your body under a lot of
strain like metabolic strain then it's
kind of like your body doesn't fall
asleep and my REM sleep's always
attacked as well if I if I if I were to
eat something like that yeah it's it's
very fascinating I think we're starting
to understand the connection of what we
eat how our gut is responding to that
and then how that potentially can affect
your sleep and then ultimately your
daytime functioning the next day but we
do recognize from sleep deprivation
studies uh that individuals will make
different nutritional choices and grab
for the cookies and the ice cream and
some of those other snacks later at
night than they would if they were well
rested that's a real horrible Paradox
isn't it it is do you know what I mean
like if you're tired then you're going
to eat bad things right before bed which
is going to make you sleep worse and
make you tired which is going to mean
you eat bad things before bed is vicious
cycle it is and unfortunately that could
potentially lead to potential weight
gain and other Downstream consequences
so just one other reason why obviously
making sure you're having sufficient
sleep but also having good practices and
your approach to sleep is also um a
priority so you're asking what else did
we do with Andre but in that ways of
preparing to sleep you know we addressed
does he have a windown routine so we
implemented one where he would read
before bed to actually relax and prepare
his brain and body to sleep for the
night managing a racing mind can be
incredibly common for not just the elate
athlete but for for all of us and so
even before he did that reading we'd
actually have him stretch and process
his thoughts outside of bed and that set
him up with a two-part system so that he
could actually be strategic about
preparing to sleep for the night a lot
of people can relate to this managing a
racing mind athletes um performers
creatives um so if I've got a racing
mind I think as well I think I tend to
feel like I have my best ideas just
before I'm about to get in bed what
would you recommend someone do if they
have a racing mind again incredibly
common to have racing thoughts thinking
through the day needing to process your
thoughts about how to prepare for
tomorrow so what I'd recommend is
spending 10 minutes processing your
thoughts outside of bed in dim light
every single night so that can mean I
would recommend you could do stretching
H you could do deep breathing exercises
to activate your parasympathetic system
and dampen down your sympathetic system
that's what I recommend for a lot of my
athletes if that's not your thing I
recommend journaling getting your
thoughts down onto paper uh or writing a
to-do list
those are easy ones that all of us can
do for even if you start with 5 minutes
today so I'm going to stretch um I've
read I read something I think it was
whoops data they released at the end of
the year where they because there's an
activity log in whoop where you
basically say what you're doing and I'm
going to butcher this but I think the
stats said that reading before bed
improved your sleep by about 5% across
everyone that was using ROP which makes
sense because you're going to be away
from Light I guess and you're also going
to be calming your you called it your
parasympathetic nervous system yes the
parasympathetic nervous system what do I
need to know about that in the context
of sleep that's just the system that
helps you relax and wind down the it is
in balance with the sympathetic system
which you may have heard is the fight or
flight system that gets you going that's
where your heartbe heartbeat will be
much more rapid your breathing can be
much more rapid when you need to go
that's when I'm overthinking yes but you
want to dampen that down and you want to
get your parasympathetic atic system
activated so you can help actually relax
physiologically your body and also your
brain so that you're in a better state
to sleep at night right it's easier to
slowly pump your brakes and then try to
sleep versus if you were going 60 M an
hour on a freeway and then suddenly
slamming on the brakes and just jumping
into bed so you actually have a process
to slow yourself down your brain and
body it will help prepare you to
actually get better sleep during the
night time just want to close off on
Andrew then is there anything else you
did with him to yes there's please give
me there's more that we've done with
Andre but this is to give you some
highlights so you know approaches to his
sleep were having that way to process
his thoughts being able to wind down
before bed and relax improving his sleep
environment so that it was as I
mentioned dark and cool I believe his
was around 67 degrees it was quiet um we
tried to we took out technology from his
bedroom so he didn't have that exposure
prior to bed we looked at cutting down
some of his power naps that were several
hours long to shorten them to 20 to 30
minutes and time it much closer to game
time so we would get that boost as you
would go into evening
games um and we looked at some of his
nutritional choices but this is the
highlight of of some of the ways that we
were strategic about his approach to
sleep and while we're also extending his
sleep from that under 7 to 7 and 1 12 to
8 hours because we knew he had an
accumulated sleep debt that had been
built from not getting sufficient sleep
probably for many months to years prior
to this and so as we've shared some of
the performance outcomes were
astonishing and he's been very vocal
about sharing his sleep story and he's
not the only one um if I could share
another story about another athlete
where you've asked what has saved
someone's career so with Andre I think
he saw this performance enhancement that
he could tap into that was that was um
previously he didn't know almost existed
right but then there's other athletes
where I think having sleep as a
foundation almost save their career one
example is Ryan Jensen so Ryan Jensen
was cut from the Ravens and put on the
practice squad and during this time as
the story goes his father said you know
what's happening you're not yourself you
like made your mom cry the other day you
know there there's something that's
going on and he eventually was tested
for sleep apnea which is a very very
common sleep disorder where your Airway
has some partial or full collapse during
the air during the night and so can have
very fragmented sleep through the night
and he was eventually tested diagnosed
and then put on treatment through what's
called a CPAP or continuous positive
airway pressure so it's a it's a mask
that provides air to keep the airway
open so then you actually can have
Consolidated sleep during the nighttime
and in a very neat way four years later
Ryan Jensen comes back signs a $42
million contract as one of the highest
paid centers in the NFL and then 3 years
later in
2021 wins the Super Bowl with Tom Brady
on the Bucks I see this as the success
story of Saving his career and he's been
vocal about how much of a difference it
made from literally almost the end of
his career happening to now being able
to succeed at the highest level and also
of course being healthier and being able
to have um more success on the field
than he probably imagined for himself
and better relationships presumably he's
not made his mother cry I'm quite
curious about that why is it that when
we haven't slept we're more likely to
make people cry because we are our
emotions are not regulated well when
we're short on sleep we are more
irritable we are more grouchy we respond
more with our emo
being able to um why we respond with our
emotions yeah what's going on in the
body is it like a different part of my
brain is it my hormones is it something
else it's probably a combination of both
right we know that um our emotional
regulation is not the same if we're well
rested versus if we're asleep deprived
and so we rely more on our innate
response which may not necessarily be
that which is strategic for what we
should be responding with if we were
tempered and had a better rest under our
belt um so we ask cognitively there's a
an implication of which part of your
brain you're going to be using but then
also you are just not in a state in
which you are going to be able to
respond in the way that you would
otherwise is it the amydala that's the
emotional center that is one that's
where like fear is very much um and
emotions and and um yeah the amydala is
where like fear and emotions are are
often centered because I've started when
I started learning more about sleep and
the impact it has on my emotions I could
see a huge VAR in how
um how I make my decisions but also how
like short I can be yeah if I haven't
slept yeah and so on the days now where
I haven't slept I literally have a
conversation with myself and tell myself
that I'm going to be in my M mdala today
so to try not to make any decisions try
not to talk to many people because
there's a risk that I might just be I
might be too short in how I consider
things and how I respond and I really
want to stay away from that but I've
seen such a huge huge variant and I've
also heard of other like famous CEOs and
stuff like that talk about how they they
focus so much on their sleep I can't was
reading something the other day and it
was I think it was it was Jeff Bezos do
you know what I'm gonna say I don't but
Jeff Bezos is someone who has been an
advocate about sleep and vocal that he
needs eight hours every night yes the
quote that I heard him say or someone
told me that he said was I think it
might have been Ariana Huffington
actually he said that his job as a CEO
is to make decisions and he says he
doesn't have to make that many decisions
a year he only makes a couple of big
decisions a year every day he's probably
just making two or three big decisions
so if his job is to make decisions then
his job is also to sleep because the
variance I see in even my own decision-
making when I'm slept and underslept is
just unbelievably staggering as someone
that sits here for seven eight hours a
day sometimes having
conversations you wouldn't believe the
difference when my brain and my mouth
are like connected because I've slept
it's like a different human being it's a
different podcast host um have you got
data to support this this impact on
cognitive performance yes so you
definitely make better decisions when
you're well rested you're less likely to
make cognitive errors you have better
judgment when you're well rested and
you're going to react faster so in the
situations where you need to make big
decisions whether it's on the field and
you need to react because you're running
a pass whe whether you are Jeff Bezos
and you're running a company and you
need to make critical decisions um under
under sometimes you know acute stressors
or you are someone who just is trying to
be your best we know that the cognitive
domain very much is influenced by
getting sufficient sleep and some of the
I would say you know large um very very
public disasters have happened as a
result of what we know is sleep loss um
where people have made poor decisions or
decisions that have led to unfortunate
disaster so for example the Challenger
disaster with a space shuttle that
exploded um and as a result there's
investigations of why did this happen
and the final report does suggest that
insufficient sleep for some of those key
decision makers around being able to
launch or not was attributed to fatigue
and insufficient sleep so being able to
make good Dame time decisions had this
disastrous effect ultimately on the
Challenger explosion or are you aware of
any studies that have measured cognitive
performance on and sleep yes so my
studies as well as many of my other
colleagues particularly look at reaction
time because we know reaction time is um
very finely or is very sensitive to
sleep loss and I'm starting to find it
also is sensitive to extension of sleep
so the other half of the story when you
pay back sleep sleep debt we see that
benefit on on uh reaction time but uh
reaction time and looking at aspects of
you know how quickly you're able to
respond or if you're having errors when
you're responding and you're not
supposed to be responding cognitively
those are um tests that are typically
used in a lot of sleep studies because
we know is quite sensitive can you give
me an example of a study that will
convince me that um if I sleep more my
cognitive performance will improve one
of the studies I mentioned before even
15 15 minutes more sleep was that
difference of that a student to the B
student there's another study I often
cite where if you look at the difference
of someone who gets 9 hours of sleep for
a full week the reaction time stays very
consistent great you want to react
appropriately you want to not make
cognitive errors or lapses in judgment
and that will be consistent over the
week if you're someone who's getting
seven hours of sleep you see a slowing
of that reaction time and then a
leveling off if you are getting 5 hours
of sleep you see an even sharper decline
in being able to react fast and then you
see a leveling off if you're getting
three hours of sleep every night you're
just going to tank that reaction time
and be slower at the same time you have
more lapses in judgment and not able to
respond appropriately but the the thing
about this study that I find so
fascinating is when we know that there's
this deficit when you're going to react
slower in the seven and the 5our group
there's this leveling off so people say
oh can I get used to getting
insufficiency sleep in some sense there
was this stabilizing of it but the
reality is you're not at your best right
we know what your reaction time could be
if you were getting that 9 hours and if
we even gave you three nights of what we
call recovery sleep so we said okay now
we get let's say 8 hours in bed for the
next 3 days you're going to feel better
and you'll probably feel more refreshed
but those reaction times for the 7 hours
and the 5 hours and the 3H hour group
didn't go back to the Baseline so it
takes more than one night night or one
weekend of that recovery sleep to get
you back to your Baseline and so that's
the bottom line that I tried to show my
athletes is that you can pay back sleep
debt but it often can take more than
just one day or one weekend of quality
sleep how long does it take so my
Studies have suggested multiple weeks uh
will really be beneficial to paying back
more of your sleep debt than just a
night or two nights of sleep the biggest
bankr tends to be in the first week or
two but obviously this depends on how
much more you're actually getting how
you're timing that in your night but the
bottom line is that if you can invest
maybe a week or maybe if you have a
vacation coming up and you do two weeks
that's going to be U the biggest impact
on paying back your sleep debt and if
you say hey that sounds like a long time
Dr ma well even potentially like 5 days
is one of my preliminary studies had
suggested in professional baseball
players even if it's 5 days of getting
one additional hour of sleep that was
shown to potential that was shown to
improve cognitive reaction time and also
processing speed in the athletes that
actually got one additional hour so if
you got six hours you went to seven if
you got seven hours you went to eight
hours versus the athletes that just
continue to get their normal sleep
interesting I I guess I've got to
understand what this concept or this
idea of sleep Deb is because I I want to
make sure I'm super clear on what it is
and isn't cuz when you say the word debt
I assume it's kind of like I I owe
the Sleep bank manager a couple of hours
um but but I I've kind of gone back on
forward on this idea of sleep debt I
think some people have told me that it's
real some people have told me that it's
not real um and I don't know where where
I should stand on it so if I if I
haven't so for example I flew into La
first couple of nights my sleep wasn't
great am I still but I had good sleep
last night am I still paying for it now
the way I explain the concept of sleep
dead is that your body requires a
certain amount every single night again
we talked but individual variability but
let's just say you need 8 hours every
night and conceptually if you don't meet
that 8 hours then you build up a debt so
if you're only getting six hours a night
you now have two hours of debt built up
if you go Monday to Friday that's 5 days
now you have 10 hours built
up right two hours every night becomes
10 hours and if you then sleep in on a
Saturday and you get let's just say 10
hours of sleep you've paid back two of
those hours but you still have eight
hours left to go and my buddy knows yes
so conceptually that's the idea of
accumulating sleep debt I do stand in
the camp that believes that that does
accumulate over time we do think that
you can pay back some of that debt on
the short term right so what you lost
like you said this past day or this past
week maybe this past month you should
pay that back with getting extra sleep
or we call Sleep extension we don't
think that you can Surplus and Bank more
and that you can pull from that in the
future but we re recognize that if
you've got insufficient sleep that if
you extend it over a couple of days
maybe a couple weeks then you will see
benefits in your reaction time in your
fatigue levels in your performance
outcomes and so we do recommend that as
a tool especially if you know that
you're going to have a day where you're
going to have sleep loss so it's a
strategy for example if you know okay in
a week I'm going to have a project and
I'm not going to be getting enough sleep
that night night then what you can do in
the days leading up to it is getting
sufficient sleep but arguably even more
so that we know when it gets to that
project the decrements that you'll
experience tend to be less robust than
if you went into it with just say that
was 5 hours so what evidence do you have
that sleep debt is a real thing what's
the first thing that comes to mind so my
my what I've dedicated my career to is
trying to understand how to pay back
sleep debt with sleep extension
interventions so what that means is
typically I'm working with a number of
Collegiate athletes where many of them
are not getting what they need because
when we start these studies many of them
have high fatigue levels they are
reacting slowly we often see lapses in
their um their judgment and their
ability to ultimately perform and
function which is what they consider
their Baseline but then when we actually
challenge them by paying back some of
that debt by getting additional hours
when we monitor the the differences that
can make over multiple weeks that's
where we see there's Improvement in the
reaction time their fatigue levels drop
their performance on the field improves
and so we recognize what has changed in
this is trying to pay back some of that
accumulated debt when the rest of their
training has been held consistent where
we've been trying to maintain the rest
of their their training which is key
which is the key point because in my
mind I go well maybe if you've got the
athlete to sleep well on that first
night then when they've showed up to
training they've trained a little bit
harder they've built their muscles a
little bit more they've had better
recovery in their muscles so
then the next day the same thing happens
because they've slept so it's actually
just that they're training better which
is causing them to improve their that's
fair we we've tried to hold their
training to be consistent and choosing
periods where their training isn't going
to vary significantly as well as you can
almost make the argument too that
sometimes as the season goes on athletes
get more fatigued more tired and that
can be actually a decrement to how
they'll perform so when we see the
benefits come down the road as the
season potentially gets even longer that
at least is some suggestion that the
intervention of sleep while we also have
the measures of how much more they were
getting actually were at least
associated with these performance
outcomes because REM one of the key
things about REM sleep which is the sort
of final stage of sleep is that it helps
with Muscle Recovery uh deep sleep is
actually deep sleep is where we uh deep
sleep is where it's implied that there's
more R Muscle Recovery regeneration
because there's the biggest pulse of
growth hormone during your deep sleep so
to back up a bit you have light stages
of sleep then you have deep stages of
sleep and then you have that rapid eye
movement sleep or when you dream that is
tends to be more associated with
consolidation of learning in memory and
skill consolidation so you go through
these Cycles during the night time about
90 to 120 minutes but the proportion
changes through the night the beginning
of the night you get more of that deep
sleep and then in the early morning
hours is when you get more of that REM
sleep so you might have woken up in an
earlier morning and had the recall of
these vivid dreams it's because you
often will be waking up from the that
REM sleep yes that happened last night
actually CU I woke up suspiciously early
for me so I woke up at about 5 or 6:00
and I was just kind of dipping in and
out of Dreams MH and were very vivid
dreams that I can still remember now
yeah um so the muscle memory element of
all of this what is muscle memory and
how is that sort of implicated with
sleep so muscle memory there's different
types of memory and you need sleep think
of sleep as hitting that save button
right you need to sleep after you have
learned new information learned a new
skill so that you can consolidate those
those uh those memories and be able to
retrieve it later so I always use an
analogy of hitting that save button
after you learn new material or learn a
new skill set you need to go home and
sleep so that it goes into long-term
storage and that you can retrieve that
the following day and subsequently
without that sleep we know that that
groundwork for that new skill or that
new memory is not going to be as strong
and so in the context of students who
are trying to study for a test or an
athlete that's trying to remember the
Playbook you want to space those
intervals that you're learning that
material and have sleep that follows so
that you strengthen those
connections and also you mentioned when
you were talking about one of your
athletes encouraging them to nap before
a game yes um I I read this fascinating
word in the research that I was doing on
your work I think it's napino yes what's
a napino the nappuccino so this is a
useful tool if you're trying to have a
temporary boost and aler and performance
so the nappuccino you go and take your
favorite caffeinated beverage the
caffeine will start to kick in in about
15 minutes and you go and then take your
20 to 30 minute power nap so if you're
able to fall asleep within that 5 to 10
minutes while the caffeine will start to
come on board then when you wake up
after 20 to 30 minutes then bam both the
caffeine will have kicked in and the
power naap will have kicked in and
there's research to show that that's
more effective for alertness and
performance Improvement for a couple of
hours than if you only did the caffeine
alone or only did the power nap alone so
the nappuccino is is a useful tool for
some who who utilize caffeine and you
can partner that together with a short
20 to 30 minute nap so if I wanted to
take a nap now I have an espresso and
then go and have my nap exactly yes the
cettas you do need to fall asleep within
about 10 minutes or else the caffeine
will start to come on board but if if
you do this in the late morning or early
afternoon it can be a helpful tool so
that you have a boost in your alertness
for a couple of hours and I grew up
thinking that naps didn't work because
the minute I learned about sleep and
these sleep cycles and that it takes I
don't know 45 60 Minutes whatever it is
to get into late stage sleep like the
Rems sleep the deep sleep I thought
what's the point taking a 15 20 minute
nap if I'm not going to get into deep or
REM sleep so there's benefit of just
that 15minute nap you mentioned you want
to stay in lighter stages of sleep cuz
there's benefits of lighter stages of
sleep and that can give you that
alertness and performance boost even
when you're in lighter stages of sleep
you actually don't want to go into
deeper stages of sleep because when you
take the longer naps as I think you you
might have shared you you've taken the
2-hour nap the three p you wake up and
you're much more sluggish much more
groggy that's not a good state for you
to go out and then do you know work
after that or it's not the state that
you want to be if you're a a basketball
player and have to go and play a game
but those deeper stages you come out of
what we call Sleep inertia with that
sluggishness and so it can also affect
your sleep at night and make it harder
to sleep subsequently so you actually
want to stay in those lighter stages of
sleep and keep those naps very short so
what's the maximum length that a nap
should be I like 30 minutes okay yes so
you can time that by setting an alarm if
it takes you 5 or 10 minutes to fall
asleep you can plan for that as well and
the setting alarm to wake yourself up 30
minutes later I think it's a great
strategy when again you don't get
sufficient sleep at night or you had
poor sleep leading into that night and
you need a little bit of a boost later
in the day what do you think of the
snooze button the snooze button I'm not
a huge fan of the snooze um I fully
understand why people love to hit the
snooze and then go back to bed uh and if
you're someone who does that one of my
suggestions is just to cut down so that
you only hit the snooze once 5 minutes
later start your day the reason why is
because it helps to maximize your rem or
your dreaming sleep in those early
morning hours if you can actually sleep
Consolidated all the way until the time
you have to wake up so for example if
you're someone who hits the snooze
button five times every five minutes for
a half hour it means that you're having
very interrupted sleep for the last half
hour of your night versus if you just
let yourself sleep Consolidated all the
way through and then maybe hit the
snooze button just one time and then got
yourself up to start your day it means
you would have given yourself another 25
minutes of Consolidated sleep likely
that dreaming REM sleep that's so
important for learning and memory and so
that is one just easy adjustment that
you can make in terms of your morning
approach to maximizing what you get
during the night so what's the what's
the value in consolidating it versus
just having fragmented sleep yeah so
then if you're getting a lot of that REM
sleep in those early morning hours and
you're snoozing you're going to be
waking up and coming out of that REM
sleep so you likely are changing the
stages of sleep you would be getting in
those early hours so you would then be
awake and then probably going into
lighter stages of sleep awake lighter
stages of sleep than necessarily having
a solid REM period all the way until you
wake up what's the cost of that so
learning a memory and consolidation is
definitely one area that we recognize is
associated with that REM sleep and so
you want as we talked about it changes
through the night you want to have as
much as possible but you part have to
have just the duration so when you get
the most of it in the morning hours if
you cut that short and either wake up
earlier or you're snoozing and you're
interrupting it you're not going to
maximize the value you get of the hours
in rem okay so I just want to make sure
that I those 25 minutes I give them to
REM sleep versus just giving them to
little fragmented light sleep exactly so
I'm better off just putting my alarm to
the time that I actually have to get out
of bed exactly just to maximize the
amount of R sleep that I get to
consolidate my memories are you a
snoozer no not really okay well I mean
we all have our moments but not really I
can't remember the last time I pressed
pressed the snooze button but the thing
that I do and I'm not sure if this is a
good idea or not is because I have told
myself and I say told myself because I'm
quite conscious of the BS that I believe
about myself but um I've told myself
that I'm like an alow chronotype or
something which by the way I don't even
know if it's true and I don't know if
chronotypes are true um and I typically
work quite late and I love working late
I get better ideas late I do my writing
pretty late at night as well and so what
I've done in my life is I've basically
made sure that I don't have any meetings
or any engagements before 11:00 so even
like this podcast today started at 11:00
yes um basically nothing in my life
starts till 11:00 for that very reason
just to because if I do end up staying
up a little bit late I want to be able
to kind of sleep through without having
to set an alarm and just wake up
naturally what do you think of that is
that suboptimal no I think it's a great
strategy so there are chronotypes where
you've mentioned you're more of an
evening owl you go to bed later you like
to wake up later as a natural
predilection is is that real or I just
myself this is justifying myself no
there is a natural tendency for some to
feel like they are evening owls and
there's others who feel like they do
much better in the morning so they go to
bed earlier they wake up earlier they're
more productive in the morning those are
are morning Larks and then there is a
group that's somewhere in the middle
that don't strongly lean one way or
another but really what you're doing is
you're you're making your sleep work to
your your chronotype and to your
advantage where you do feel like you're
more productive in the evenings and then
you want to be able to maximize your
sleep waking up without an alarm and
starting your day later I think that's
like a great strategy because a lot of
people aren't able to have that
flexibility and so Society often will
force particularly the night owls onto
an earlier schedule where you have to
wake up whether to go to work or other
obligations or kids earlier Point yeah
and and then you're cutting your sleep
short like you mentioned like with
school and then we're getting these um
and then you're on a schedule that
doesn't work synergistically with what
your chronotype is they should do some
studies on kids in school and like
Disobedience and ability to pay
attention and do homework in grades
because honestly I was so useless in
school and I really I really think of it
now I'm not entirely sure here because I
got diagnosed with ADHD when I was like
30 years old so part of me thinks I've
just got like a very active brain and
part part of having an active brain
meant that late at night I was Finding
ways to stimulate it by playing Video
Games Etc so that might just be the
reason but the other reason might be
that I'm an Al Chron type and I found it
really hard to get up at like 7:30 to
get to go to school by sort of 8:30ish
and so I would miss school I would show
up knacked I would sleep in lessons um
and I feel like school just starts way
too early for kids it's a ongoing uh
it's an ongoing problem and actually in
a very interesting way there has been a
change to school start times
particularly in California um this this
year was the first year that school
start start times for high schools and
for middle schools was shifted much
later because there are studies to show
that our when our students are better
rested they have higher attendance rates
their GPA and grades are much higher
there's less mental health issues um
there's less car accidents and so this
these Studies have um been over the last
decade and longer in which they have
built evidence to help make decisions to
start school time later um and that is
in California been enacted this year and
some other states are starting to follow
suit but to your point what makes it
challenging is that at the age of high
school many of those body clocks are
shifted and so students St want to an
adolescence go to bed later and wake up
later naturally that's just how our
sleep changes through the life cycle but
when they stay up late and then we cut
their sleep short by forcing them to get
up really early for school now they have
insufficient sleep and that builds like
a sleep debt and so they're not setting
themselves up for success in school for
learning and memory so that's where
again there's more evidence of if we can
shift the school start time get these
students to have a little bit more sleep
they ultimately are better prepared for
school come to school have less uh car
accidents and are just healthier
students do you think there's anything
parents need to know about sleep when it
as it relates to their children and
sleep hygiene with their children I
think it's important for parents to
start at the early early years of
instilling good sleep habits a good
sleep routine and giving their their
children the tools and skills to be able
to make sure that it's a priority as
they go through early childhood into
adolescence and hopefully then sets
themselves up for making sure it's a
priority for their adult life um I'm a
young parent myself I just had uh my
first son and so um I recognize and can
empathize with the TR the struggles of
getting sufficient sleep when they're
very young but then trying to instill
how they can approach their sleep from
early age I think would be incredibly
helpful to also just change culturally
how we think about sleep because so many
of us now have never learned about sleep
for or what we should do until you're an
adult but if we can make that change
earlier on I think we're going to have
healthier kids better families um who
are better rested and and also just this
generation where we recognize this is so
important that we shouldn't sacrifice it
because we're doing ourselves a
disservice to letting us be the best
that we can possibly be how old is your
son 11 months 11 months so how are you
sleeping oh I transparently am quite
tired okay I I as a yeah new Young mom
also um I don't have the ideal sleep
that I know I would love um it's a for a
short time but I'm trying to be
strategic of the things that I can do
with some of the tools that we've talked
about trying to leverage power naps um
when for example I do have to still wake
up during the night time to tend to him
um and you know the early morning starts
are not always consistent so my sleep
schedule is not always consistent so you
know going back to those three buckets
we talked about earlier like if I don't
get the full duration that I want then
how do I maximize the quality right I've
optimized my sleep environment I try to
have a process to wind down at nighttime
um or the timing you know is and the
sleep schedule is another area that you
can still work on when for example you
may not be getting the duration um so
these are strategies that I try to
employ when I know that I um also am a
work in progress and trying to get the
best sleep possible Once Upon a Time if
you had a business idea it was
exceptionally difficult to get going but
now in the age of Shopify it is
exceptionally easy as many of you will
know Shopify are a sponsor of this
podcast if you don't know Shopify it's
an exceptionally simple web platform for
anybody that's got an idea that wants to
transact on a global scale so things
like these conversation cards which we
sell we've sold using Shopify and it
only took us a couple of clicks to get
going so why did we choose Shopify for a
number of reasons but I think one of the
big ones which goes and appreciated is
their checkout system converts 36%
better compared to other platforms and
here's what I'm going to do to remove
the cost for you if you go to
shopify.com Bartlet you'll be able to
try Shopify for
$1 a month I've seen Shopify completely
change people's lives and for many of
you I think it could change yours what
are the other examples of sort of case
studies that you're you're most proud of
or that were most pivotal in shaping
your thinking about sleep I mentioned
the Philadelphia Eagles back in 2017 and
tried to help them educate their players
about sleep how to have a more strategic
approach to their wind down routine to
thinking about how they're integrating
sleep into their training practices and
thinking about ultimately how they
travel and and having for example
strategies to minimize jet lag when
you're Crossing time zones and having to
play in different locations than the
give me some of those then so some the
tips you'd give me someone that travels
a lot yeah um pre- during and post
travel yeah what should I be thinking
about before I travel while I'm
traveling and after I I land yes so have
a a game plan for every trip I think
most people have no strategies in place
when they travel they just get onto an
airplane get to a new location and try
to adjust when they get there that is
not really a great strategy you want to
have at least a pre-flight strategy
inflight strategy and post-flight
strategies because that will set
yourself up better to minimize jet lag
also travel fatigue and ultimately then
be able to acclimate faster if you're
Crossing multiple time zones before
pre-flight try not to panic pack I know
all of us do do Panic packing right
before bed right before we're getting on
a flight um so you want to try and be
strategic and pack early you want to get
at least why do I want to not panic pack
because most people will Panic pack the
night before they they have a flight and
then they'll cut their sleep short so
they'll get only say 5 hours of sleep
because they're staying up late trying
to pack everything and get ready for
that early morning flight or for the
next day well I I pack the morning of
travel so okay but I'm I'm out here in
La for I'm out here for 2 weeks and I
packed a carryon carryon suitcase okay
cuz I so look at what I'm wearing I wear
just the same outfit every day so I have
like the same outfit um but I pack
literally an hour before I go to the
airport okay okay so but you're right it
does cut my sleep because I could have
been in bed whether it's beginning of
the day or the end of the day if it's
affecting then the duration of your
sleep I would recommend trying to a
little more strategic and do it a day
before two days before don't pain it
pack number two try to get at least
those seven hours if not
your your amount of sleep that makes you
feel like you're functioning and
Performing well um at least a day if not
two days if you get insufficient sleep
before you get onto an airplane jet lag
will be worse and that travel fatigue
can feel much more robust and you're
more likely to have the quas on in the
airport which is going to destroy the
whole thing for for you so those are
things that you can do before flight
depending on where you're going you can
actually start to adjust your body clock
before you even get onto the airplane so
let's just take a 3-hour time difference
here in the US if you're in the west
coast and you're going to the east coast
three time zones you can actually start
to go to bed a half hour early wake up a
half hour early do that for two or 3
days and and get sunlight in the morning
because that sunlight reinforces to your
brain to start to shift that body clock
so if you can do that a day before 2
days before maybe 3 days before when you
actually get to the new location you
don't have to shift your body clock
three time zones you've already shifted
it one time zone or two time zones
because the rule of thumb is for every
time zone you cross it takes about a day
to re acclimate even if you feel better
after the first day usually jetti feels
the worst in that first day when you
arrive um but physiologically you
haven't really adjusted fully even if
it's over you know a couple of days so
that's the rule of thumb so those are
some things pre-flight you can do when
you're in Flight you want to hydrate
throughout the flight because
dehydration can worsen jet lag you want
to think about getting onto the new time
zone schedule so again depending on
which direction you're flying and how
many times when you're Crossing you want
to start to synchronize perhaps like
when you're actually sleeping or some of
your meal times so that you're getting
onto that schedule and then you partner
that with for example building a travel
sleep kit I'm a huge fan of investing in
sleep tools that will help you sleep
when you need to in non- ideal
situations whether you're on the plane
and now trying to take a nap or shift
your sleep schedule then you actually
have an eye mask and ear plugs you have
noise cancelling headphones you have
your own travel pillow you have the
tools with you to S drugs sorry sleeping
medication okay so some uh medications
can be helpful like melatonin
particularly if you're trying to advance
your clock has um evidence that it can
help shift that a little bit more
quickly when you're trying to advance
your clock earlier would you recommend
it to athletes um it I would say if it's
something that you've used before and
you know that you don't experience some
of the side effects it could be a useful
tool so melatonin while it's one of the
most commonly used supplements and sleep
aids there are still side effects that
to be wary of so specifically for
athletes too you can feel more groggy
and sluggish when you wake up from it um
it's not regulated by the the FDA here
in the US and so you don't always know
what's actually in those supplements so
for my lead athletes they use what's
called NSF Sports certified versions um
they're just there's more um regulation
around them but in for the for the you
know everyday person you know there's a
study where they looked at the amount of
melatone that was actually in a variety
of these supplements and it was a wide
range from over 400% of what was on the
label to obviously sub you know you know
uh under 100% of what they actually
indicated so there's a wide range of
what's actually going to be in the
supplement but it can help particularly
when you're on travel with um re
acclimating my team here we most of them
use a certain app when we travel and it
just tells you basically you say where
you're going and then it'll tell you
what time to eat what time not to eat
Etc so you can get aligned with that
with your destinations like circadian
rhythm I guess so we'll link below one
of the apps that our team use we're not
affiliated with them in any way but
we're flying out here I know will and my
team sent me a screenshot and said Steve
this is what time you need to be eating
and everything cuz we're going to La so
it's been super helpful for all of us I
I'll link that below because I know some
people are going to be wondering what
apps they should be using so we're in
the flight we've got our postt trvel
flight kit with the ey masks and all
those kinds of things in we've got our
app is we're
hydrated um noise cancelling headphones
is there anything else we need to be
thinking about while we're traveling
when you're traveling so on a plane on a
plane so we talked about hydration minim
Al and caffeine or eliminating entirely
is a straty inad of having on board
because that can also potentially worsen
um jet lag and or make it more difficult
to sleep when you're actually trying to
when you arrive and again seeking light
that is the most powerful signal to your
brain to help shift your body clock also
bringing sunglasses so that you actually
avoid sunlight at certain times because
your body can respond differently
depending again on your home location
and how many time zones youve crossed so
there's certain times that these apps
can be helpful that will likely tell you
you don't want to get sunlight during
these hours and so you want to be
strategic about that and just make sure
you have sunglasses so that you can
still go about your day but trying to
minimize that sun exposure um getting
well rested and getting sufficient sleep
even if it might be a little bit more
fragmented than usual just giving
yourself at least a day to acclimate so
that I would recommend not scheduling
your most important meetings right when
you get in or in that first day for
athletes they don't want to do maximal
exercise because there's a risk that
that jetl could increase injury in that
acute period so you want your body clock
to be able to readjust and then using
caffeine and power nap strategically so
for example our afternoon 1 to 4:00 is
typically when we have this dip in our
alertness now when you get to a new time
zone that can occur at a different time
point in the day but strategically then
you can use CA and and uh Power naaps to
be able to help you through those lulls
when you're in that new time zone what
about sex sleep and sex in bed and that
is it because I think so many people
actually make the mistake of being in
bed and being on their computer on their
phone doing other work while they're
awake and that actually helps strengthen
that connection that when you're in bed
you're awake and your brain will start
to associate that so sleep and sex are
all that you want in bed everything else
should be outside so when we talked
about that wind down routine or that
racing mind all that should happen
outside of bed because you want to
actually tease apart that Association
that your brain is making of being awake
in bed and that will be one small
adjustment that's helpful to to get
better rest at night but will will sex
improve or hurt my sleep I'm thinking
you know CU I'm really trying to get out
like should you be in bed with someone
does it does it improve your sleep to
sleep with someone and does sex have an
impact on your sleep cuz I you know
speaking from personal experience I
think that if I have sex before bed I
sleep better I don't think that there's
great literature on sleep and sex out
there but um I will say that there has
been um there's definitely an impact
potentially of a bed partner sleeping
with you in bed because their movements
can affect your sleep if they snore that
can very much affect your waking up
during the night time um and then you
know with sex I think that that is
something anecdotally some people will
definitely say it helps them to be able
to consolidate their sleep and they feel
like the quality is better um but I
don't think there's a lot of great
studies that are are being funded for
research right now what is the most
popular question you typically get asked
about sleep from people most popular
question is napping which we've
discussed keep them short 20 to 30
minutes I I get asked a fair amount
about can you oversleep so no we don't
think you really you should you can
overs sleep when some people say they
get say 9 hours or 10 hours and feel
much more groggy it's because often
they've shifted their sleep schedule or
they have an accumulated debt that say
built up and then they're finally
allowing their body to relax and so now
that they're they're they don't have the
mask of stimulating activities from
their day or their work that can read I
read I didn't read a study one of my
podcast guests told me that there is a
harm to oversleeping but I think from
what I managed to
ascertain the studies they were citing
just proved that people who sleep for
like 10 or 11 hours
typically have a higher risk of um
disease and mental health but then it's
hard to establish cause and effect
because if you're in bed for 11 hours
maybe you're a depressed and B one would
assume you're exercising and moving a
little bit less so you probably got a
lot of like cardiovascular issues yes so
there are studies of looking at the more
extremes of Less hours of sleep and then
even more hours of sleep like the 10
hours and obviously there can be other
comorbid conditions uh that go along
with individuals like who sleep much
longer you mentioned you can sleep much
longer because of depression or other um
chronic health issues and so um that's a
different context of thinking about
oversleeping I think in the question I
typically get is oh I slept one night of
10 hours and I feel worse so I'm never
going to do that again and that's
actually not true right I think we want
to have just more consistent hours that
are timed so you're not having a shift
in the bedtime and wake Time by like
three hours later um because that could
be why you're having that grogginess
when you wake up not because you got the
10 hours but because you're waking up up
now at 11:00 a.m. instead of your
typical you know 8:00 a.m. wake up time
um you could be more dehydrated because
of that longer time um snoring is one
that I get asked a fair amount about is
you know is it completely benign and I
would say if you're snoring you should
go talk with your primary care doctor
and you should potentially ask about
getting a sleep study there is Sleep
Disorders like obstructive sleep apnea
we mentioned before that's incredibly
common and that's when that Airway has
partial or full collapse and can lead to
very fragmented sleep so you can wake up
not refreshed because you really didn't
get quality sleep during the night time
and snoring I think in our society has
become just an accepted Norm that can
happen as you get older but that is not
always the case that it is uh a benign a
benign symptom and so um making sure
that you talk to your primary care
doctor and potentially get a sleep study
I think is incredibly important is sleep
apnea the the most common um disease
disorder you see yes yes it
isapa can be incredibly common I believe
it's about 26% of people of people in
the ages of 30 to 70 and so that as you
imagine that's like one in four
individuals but many individuals don't
actually get tested or diagnosed and
then treated until they're way into
their adulthood or even pasted into
their 6070s so with asleep apnea often
times people will not wake up refreshed
they will often feel tired in the
daytime they may have a lot of caffeine
or have to rely on power kns to keep
their alertness up a lot of individuals
will have early morning Awakenings so in
those 3 4 5:00 in the morning they'll
wake up and not realize why they're
waking up frequently snoring can be very
common if you've ever had a bed partner
or a roommate and they've ever noted
that you stop breathing or pause
breathing or gasp and choke those are
very suggestive that you might have
sleep apnea um and again it is
incredibly common but very manageable so
something that I would highly recommend
if you your bed partner your your
roommate snore just uh suggest to have
um I would suggest they go see their
primary care doctor and typically is it
people that are slightly overweight that
are more likely and susceptible to
having sleep apnea yes yes a lot of
individuals who are overweight or obese
um will be more at risk for Sleep back
as you imagine the collapse of the
airway typically is here around the neck
and so more weight um typically is is
not helpful for for apne but you can
also be a very fit healthy young
individual so I work with Elite athletes
and I have a number of my professional
athletes who again are young healthy
males but their Anatomy is just more
susceptible for this condition what are
the um the big rebuttal you get the big
excuses that you hear from people I
don't have enough time
yeah I don't have enough time to sleep
okay I don't have enough time to sleep
and what do you think of that one uh I
don't think that that's true I think we
we all are going to make sacrifices and
priorities in our day and I think if you
are saying you don't have enough time I
think there's ways to be strategic about
how you manage your time in the day I
think we all have five minutes to
implement a windown routine we can all
do that at the very least I think all of
us can um optim ize our environment I
think we all can invest in some sleep
tools I think we can make better choices
about how you go about your day so you
set yourself up better for sleep so I
think that those are just small
adjustments but will be huge in terms of
what that will mean at night um I hear
that you know I will sleep you know I'll
sleep in the offseason right now in
season is when I want to focus on being
my best but really I think that's the a
backwards way of thinking about it if
you're thinking about optimizing your
sleep when it gets to the season or the
postseason when some of the most
important games come down the line
you're just playing catchup because if
you have a sleep that built up and
you're just trying to maintain that
through the season you actually are at a
deficit versus the other guy or growl on
the team who has paid that back in the
off seon now you have given yourself you
know zero sleep debt you're at your best
and now you're just trying to maintain
that through the
season what about injury what if I if
I'm an athlete and I'm underslept are
there any studies that suggest I'm more
prone to injury there are a few studies
that do suggest getting insufficient
sleep so under 6 hours there's been more
fatigue related injuries in adolescent
athletes there's also a study that has
looked at under eight hours of sleep
still has a increased risk around 1.7
fold higher of inj fold 170% yes yeah of
higher risk of injury when you're
getting under 8 hours of sleep versus
those that got more than 8 hours of
sleep and so I think it's unclear
exactly why you're specifically more at
risk for injury but I tried to take a
look at the biomechanical changes of
what happens when athletes are not
getting sufficient sleep in one of my
early studies um that has explored the
biomechanical changes and what we showed
is that when you're not getting
sufficient sleep for multiple days you
have more more variability in your
biomechanics yeah so you're moving
differently so you're not actually
selecting probably your preferred
coordination strategy so for example I
had them doing a vertical jump and if
you're well rested you likely should be
able to do that very consistently as an
elite athlete but when you're not well
rested it's much more variable so
they're moving differently and that may
put people at risk for injury they like
Landing differently a little bit jumping
yeah how their knees their hips um are
coordinated together differs and so that
may put you at risk for injury down the
road but more to come hopefully on that
front there's just not that many studies
that currently exist I've noticed
something recently because recently I've
had to get up quite early on a few occas
so when I say early I mean I've had to
go get wake up at 4:00 a.m. because I've
got a flight at 6:00 a.m. and really
interestingly if I so say if I go in bed
at like 11:00 p.m. at night and I and I
have to wake up at say 3:00 or 4:00 a.m.
when I wake up at 3:00 or 4 a.m. I'm
really hungry but if I wake up at 8:00
a.m. M I'm not hungry well you are
starting your day much earlier so your
body clock is starting at a much earlier
time than you typically would versus
8:00 so you almost have what we call
socially jetlagged yourself right where
you didn't get on an airplane yet but
you literally shifted your whole sleep
schedule to be an earlier wakeup time
and so you can feel some of the symptoms
of jet lag where you can have and you
can have stomach GI upset you can feel
more fatigued you can have those
symptoms as if you gotone onto a new
time zone and flew there but you hadn't
yet if it it almost feels dare I say
like hormonal like it because I was
trying to understand what hunger is and
hunger is essentially a bunch of
hormones isn't it so yes you have
certain hormones that regulate your
appetite so leptin and gin are two
hormones that impact your appetite um
gin makes you more hungry leptin feels
more satiated if you don't get
sufficient sleep these levels can be
imbalanced and so that's where people
tend to as we've talked about grav
gravitate towards you know carb and
unhealthy Foods in the later evening
time um but also when these are not well
balanced that can also lead to weight
gain or situations where you're not able
to potentially um regulate your weight
appropriately and so when I have
individuals who are wondering about not
making weight goals I ask them about
their sleep and they don't recognize
that sometimes being able to address how
they sleep will actually help them to
get to the weight management goals that
they're really striving for Jack what
about you we've talked about sleep
before how how are you sleeping at the
moment I've got pretty good at my sleep
but waking up in the middle of the night
you spoke about it in terms of like
sleep happena but it feels like it
should be normal to wake up so
Awakenings actually can be very normal
this is a very common question I get
asked is you know should I never wake up
at night and that's actually not true so
you shouldn't necessarily hit your head
on the pillow and then you're out for
the full night and then never have an
Awakening if you wake up you go to the
bathroom one time you come back fall
asleep in the 5 to 10 minutes great
that's actually very normal um so you
can have Awakenings that happen at even
in the early morning hours and that can
be just a typical part of your sleep
cycle because it can be as your
transitioning between these sleep stages
that you'll have these Awakenings
sometimes you'll consciously know that
you're awake and other times you will
unconsciously awaken um and so something
like a wereable might actually show you
that you have these Awakenings during
the night time that you don't recall um
but when it becomes very frequent then
you have these Awakenings and over
multiple weeks or it makes it more
difficult and challenging than to
function in the daytime that's when we
get more concerned about Awakenings
because there's a number of ways reasons
why you can awaken at nighttime um to
name a few it could be environmental
factors that affect your sleep it could
be that you had alcohol you know that
right before bedtime maybe there's
caffeine that's causing you to be awake
there's also just stress or if you just
have a racing mind that potentially
could cuse those Awakenings a bed
partner is something that is a common
culprit um or underlying sleep apnea
that can happen and so there's early
Awakenings that need to be investigated
with your doctor how much does um
alcohol impact my sleep in percentage
times I I don't know the specific
statistics of how that's going to impact
um um the the duration but I will say
that when we look at the studies of
moderate to high consumption of alcohol
that very much has a association with
more fragmented sleep more Awakenings
during the night time and so the quality
of your sleep is significantly impaired
so if you're trying to um have an
important meeting the following day an
important game or you're just trying to
be able to be your best that following
day at least try to minimize or
eliminate the alcohol or in the sleep in
the sleep docks world we say drink when
you wake up we'd rather you have that
alcohol in the morning or the or the
early afternoon not not necessarily
right before bed and so um yeah that's
that's one of the strategies is to
eliminate the alcohol right before
sleeping Dr M we have a closing
tradition on this podcast where the last
guest leaves a question for the next
guest not knowing who they're going to
leave it for and the question that has
been left for you is if you could go
back and fix your worst mistake but it
would change everything afterwards with
no
guarantees would you do
it no I would not do it I think we make
mistakes in life and we learn from them
and we adapt and we it can set us off in
a different direction but that
ultimately is going to influence who we
become who we interact with how we build
a life forward and I wouldn't change my
life life if I could go back and it
could would set me on a completely
different trajectory could you think of
a worst mistake when I said that did one
come to mind or was that a category of
there wasn't I maybe I haven't spent a
lot of time to try and dive into some of
my worst mistakes I definitely have made
mistakes along the way and uh obviously
would have done some things differently
in my personal or professional life but
I do think that that is what has made me
who I am today right I think I have
tried to learn from those mistakes
try not to make them again um and try to
figure out how to adapt from there but
that has I think set me on a path that
uh is where I am today so I wouldn't I
wouldn't change that it's so interesting
the subject of sleep for me because I I
was part of the like burnout Brigade The
like badge of honor burnout Brigade for
a long period of time and I I definitely
thought in my early career when I
started my first business around 18 19
20 21 up until probably about I'm going
to say up until about 26
I thought that me not sleeping was
something to show off and I thought that
I was more impressive if I communicated
to people how little I slept and how
much I was able to accomplish in spite
of that I think actually the greatest en
enabler to my productivity is like being
really obsessive about my sleep and
having that rule that I said where
nothing in my life unless there's a
something that's immovable is booked
before 11 o00 and I really hope other
people um after listening to you after
going through your work which is all
available online really prioritize their
sleep because as you've shown through
your research and the studies the the
impact the very real impact on our lives
is so profound maybe one shift in your
mindset too that I encourage you but
everyone that's listening as well is the
way I frame it to athletes is it's a
small tweak but if you think about sleep
is not the end of today it's the
beginning of tomorrow what you do to
prepare
what you do to try and get the the
duration that you're striving for and
how you set yourself up will affect
everything about how you function how
you interact with individuals and
ultimately perform tomorrow if you're
willing to do everything it takes for
you to be your best sleep has to be
foundational in every day and if you're
willing to put in that time and that
effort you'll reap the benefits that
come down the line and it can be
completely
lifechanging but you have to give
yourself that Grace and that patience to
be able to make these small adjustments
but as some of my athletes have shown it
can be a GameChanger for them it can
completely change the trajectory of
their career and even life once they
actually get quality sleep under their
belt and so I challenge everyone to make
small adjustments starting tonight and

interconnected subjects of sleep and
well-being generally but also I've

popping up through a Tesco or to a
waitrose they've grown by almost
10,000% in a very short period of time
because people are sick and tired of the
typical unhealthy energy drinks and
they've been looking for an alternative
perfect Ted is the drink that I drink as
I'm sat here doing the podcast because
it gives me increased focus it doesn't
give me crashes which sometimes might
happen if I'm having a three four five
six hour conversation with someone on
the podcast and it tastes amazing it's
exactly what I've been looking for in
terms of energy that's why I'm an
investor and that's why they sponsor
this podcast and for a limited time
