He was literally two days away from

dying. So, this is a story where a

15-year-old boy was diagnosed with blood

cancer, but he developed a flesh-eating

infection in his lung. He wasn't going

to make it. So, he has one request. He

wants to go outside, and that's exactly

what they do. And this was actually

mind-blowing to me. After the second

day, the infection is probably 60-70%

gone, and it became clear to me that

sunlight has so many important benefits.

For instance, if you're the bed closer

to the window, you get discharged from

the hospital faster. So, I want you to

give me any any information you have as

it relates to light health. For example,

do you recommend these kinds of things?

Dr. Roger Seholt is a board-certified

critical care physician who breaks down

complex science into clear, life-saving

advice. I see people at the very end of

their lives, so I know what prevents

them from getting this ill and how to

extend life. So, let's distill it down

into eight pillars. The first thing that

exercise, it reduces stroke, it reduces

depression. Next, sunlight. Did you know

that infrared lights from the sun is

able to penetrate up to about 8 mm and

stimulate and upregulate melatonin,

which prevent a lot of diseases like

dementia, cardiovascular disease,

diabetes.

>> What if you live in a cloudy country?

>> There's some very actionable things that

you can do, and we'll talk about that.

Next one, water. For instance, people

who use sauna are more likely to have

less death from cardiovascular disease.

Next, air. There are studies that show

that just going out one day a week can

elevate our immune system and make us

more relaxed. And then there's

But finally, trust. This is something

that can't be ignored because studies

have shown that people who have a good

faith and trust in a God are good.

you're a subscriber to this channel,

that would be tremendously appreciated.

It's the simple, it's the free thing

that anybody that watches this show

frequently can do to help us here to

keep everything going in this show in

the trajectory it's on. So, please do

double check if you subscribed and uh

thank you so much because in a strange

way you are you're part of our history

and you're on this journey with us and I

appreciate you for that. So, yeah, thank

you.

Dr. Roger Schwelt.

With the work that you do, what is it

that you're aiming to accomplish?

Outside of my clinical duties, uh and

maybe even part of that, I would like to

clearly

explain

very easily graspable tools that can be

implemented to make people live their

best life and it's specifically in terms

of their health and their well-being.

And as we dig down into health and

well-being cuz that's quite a broad

Yeah.

>> basket, what is it within health and

well-being that you've spent your

career, your life focusing on? So, I'm a

board-certified internal medicine

specialist. Then I did an extra 3 years

of training uh here in the United States

on pulmonary and critical care. So, I

deal with all of the issues that are

related to the lungs and the critical

care aspect. So, if you are uh

if you were admitted to a hospital and

you're critically ill, you'd go to the

intensive care unit. I'm the doctor that

you see. So, I'm putting in, you know,

the lines, putting them on vasopressors,

intubating them. Uh I worked in the

clinic this morning.

And what are some of the unappreciated

things that most people don't think of

cuz we think of, you know, don't eat

processed food and exercise. But, is

there things outside of that that you

don't think the average person

appreciates enough? Yes, absolutely.

What are those things? So, if we look at

those things that extend life

and are beneficial, we could put them

into what I call eight pillars of

health. If you can imagine your life is

uh a chain with a bunch of links, okay?

And I'm talking medically.

Each one of those links is an organ

system.

So, your heart is a link. Your lungs are

a link. Your liver is a link. Your

kidneys, etc., etc.

As you go through life, imagine those

links starting to erode.

So that at some point in your life,

you're going to get some sort of a

disease or a diagnosis that focuses on

one organ system of your life. For many

here in the United States and in the UK,

it's the heart.

And as that link gets more eroded,

we can see very clearly that this is

going to be the link that's going to

break first. And therefore attention is

paid to that link. For many, that

diagnosis comes with medications. So

here here is where the first truism that

I would say going forward, all

medications have side effects.

And what the aim is to do in modern

medicine is to utilize the knowledge of

those medicines and their effect on the

human body so that we leverage the other

links to protect that weakest link. So I

could go through a whole bunch of

medications that I give all the time to

patients in the intensive care unit,

where I'm focused on saving their life

because I can clearly see which link is

the weakest,

but I'm doing it knowing that there's

side effects because I'm trying to save

that link to save that life. And I'm

leveraging those other things. For

instance,

somebody comes in with a stroke.

And

they have they've they've lost weakness

on the on the right side of their body

or on the left side, whichever side.

I can give them a medication

immediately that will break up all of

the clots in their body. It's called TPA

or TNK. And it will restore blood flow

to the brain and it will reverse many of

their symptoms. If they come in soon

enough, we can do this.

What's What's amazing is that that

medication has an effect that can do

that, but it also has a pretty

significant side effect in that it could

break up clots somewhere else and cause

bleeding.

So we have to be careful about what it

is that we're doing.

Clearly there, what we're doing is we're

saving one link at the expense of other

links, but that's what you have to do in

an emergency situation. But if after

that, I simply send that patient home

without telling them why they had that

stroke and what they need to do to

prevent themselves from getting that

stroke again, and what are the lifestyle

factors that caused that to happen,

I haven't done my job. So, what is what

are the interventions that we can do

hopefully early on in life

so that we don't have those links

eroding, so that all of the links are

strong, and as we get older, we can

continue to strengthen all of the links.

Here are the eight. So, nutrition.

That's That's nutrition. Basically, you

know, we know there are studies that

have done that showed that that

depending on what we put into our bodies

as food can have a dramatic impact in

terms of our well-being. Okay? So,

that's nutrition. Exercise.

As I was saying, exercise not only I

mean, drugs and things have side

effects. Exercise have side benefits.

So, exercise obviously is going to make

you more fit. It's going to make you

have better endurance.

But did you know that it reduces stroke?

Did you know that it improves

uh well-being? It reduces depression.

There's so many benefits. So, all of

these links are actually improving.

There's no leveraging here.

Exercise is incredible.

Water.

So, this may sound obvious, right? Like

you drink because you're thirsty. Where

I would like to go today is to talk a

little bit about what the effect of

water externally on your body can do.

And you're talking there about like hot

and cold

>> Exactly. usage. Exactly.

>> or cold plunges, saunas, that kind of

thing?

>> Exactly. Okay. And we'll get into the

actual evidence for this. We'll get into

it later, but what is the potential

>> system.

Which changes your probability of

diseases and stuff like that.

>> Correct. Absolutely. Especially in the

acute setting. Especially. So, not only

in the acute setting, but we also have

pretty good data from Finland, where

they have more saunas than almost than

people,

uh where they've actually done the

research and and shown with dose

response curves that this is actually

very beneficial. We won't get into too

much of that, but what I want to focus a

little bit more on because of my job in

the intensive care unit

and what we're seeing right now with

viruses and mutations and the innate

immune system, why something like this

may actually be very important, uh, as

we look forward. Interestingly, as we

look forward to future famous pandemics,

we can look backward and see what we had

done in the past. And we've got some

really actually really good information

on that. Let's go to

sunlight. This is something that, um,

I've really become more and more

involved with because of some of the

benefits that that this can do.

A very big misconception that people

have is that sunlight equals vitamin D.

And therefore, if you take a vitamin D

supplement, you don't need to go in the

sun.

This is really something that's uh, now,

um,

being debunked. Sunlight has far more

benefits than just vitamin D. Not saying

that vitamin D is is not something that

you want to supplement with. I

supplement with vitamin D. I think it's

there's a benefit to supplementing with

vitamin D, no question. But sunlight has

so many important things and I and I

really would like to spend the bulk or

the lion's share of the time talking

about this because this is really

important. Okay.

Um,

this is a this is this is amazing. Uh,

and it really made me think about

sunlight.

So, this is a story

by a lady by the name of Amy Hanmeyer.

Her 15-year-old boy

was diagnosed with lymphoblastic

leukemia, went into uh, the hospital,

actually started chemotherapy for it.

Which is blood cancer.

>> It's a blood cancer, yeah. And so, this

the treatment for blood cancer is

chemotherapy, which he started. The side

effect of chemotherapy is suppressing

the immune system.

And unfortunately, he didn't realize it,

but he developed uh, he didn't realize

it immediately, but he developed a a

fungus flesh-eating infection in his

lung.

And went into the hospital in June of

2024.

Uh this is in Minnesota, tertiary care

hospital.

And he

got worse and got worse and got worse to

the point where the only way that they

could control this infection was to

actually remove his left lung, which

they did.

So, this is a 15-year-old boy.

He is without his left lung. He only has

a right lung.

And he starts to decline even after

that. They do a CT scan and it shows

that now the infection has moved to the

his remaining right lung.

They have a family conference.

And as Amy is telling me this story, I

could hear her choking up. She's telling

me this on the phone.

She's saying that he's 15, he's

completely awake, he's completely alert.

He knows everything that's going on

around him. He's on a ventilator like a

a machine that they use for for sleep

apnea. It's like a BiPAP machine that's

breathing for him. It's not intubation,

but it's on his on his mouth.

And the doctors, you know, have done

everything they possibly can and they

say, "Look, he's getting worse. We can't

take Obviously, we can't take the right

lung out. We can't put him on a

heart-lung machine because there's no

sort of destination to where he's

going."

Uh

we recommend not intubating him and

making him what they call DNR, do not

resuscitate.

So, they're like, "Wow." They were not

expecting this coming. So, they have a

big conference. Somebody they they call

in help to like, "How do you explain to

a 15-year-old boy that you're dying?

And how how's that going to feel?"

So, they asked the doctors, "How how

much time does he have?" They say, "2

days."

So,

in this in this situation,

they ask this boy,

"Okay, you're going to die.

What do you want to do with your life in

the in the next 2 days? What do you want

to do?

And surprisingly, he says, "I want to go

outside."

"I just want to go outside."

This this guy grew up probably on a farm

or something and he spent his time

outside. So, he wants to go outside.

So, you know how

I mean, I don't know if you know this,

but like if you're a nurse or you're a

doctor

and you've done everything you can and

this and you're just completely

horrified at the fact that this

15-year-old is going to die and he has

one request, you're going to move heaven

and earth

to fulfill that one request. And that's

exactly what they do. They

get this boy the hospital bed outside.

He's on a BiPAP machine the respiratory

therapists have put together. So, this

guy is outside.

And they're not putting him outside to

get better.

He's just this is his dying wish. They

also use this thing called a Firefly.

It's like a a light device that they

were using. I to I'll be honest, I don't

know which did it. The Firefly was the

It's a It's a light device that gives

off light at different wavelengths and

they would use that for about three

times a day for 5 minutes.

This guy

does not die.

After the first day

his white count starts to come down.

That's like a a measure of the infection

that's going on in the lung.

And and and by the way, they do a CT

scan of his lung before this all starts

and the and it's just the the the

remaining lung on the right is just

filled with infection. It's horrible.

By the By the second day, the white

count comes down even more. And and by

the way, they haven't changed any of the

other treatment. He's been in By this

point, he's been in for 6 weeks.

He has not seen the light of day.

And and he's still getting the powerful

antifungal medication amphotericin B and

posaconazole. All of these things are

are really high-powered drugs that that

just completely fight fungus, but it's

not working. He's getting worse.

But now, he's out for the second day.

The white count's coming down, which is

good. That's a good sign.

His oxygen requirement is coming down.

That's a good sign. He's requiring less

and less oxygen. By the time he gets to

day five,

okay, we're already past two days.

He's off the BiPAP. He's on regular

just nasal cannula oxygen that you see

people wearing on their nose.

The doctors are scratching their head.

They're like, we we should get a CT scan

to see what's going on.

So So, Amy tells me that they they get a

CT scan of this guy, and they're in the

room. And some some even like swear

under their breath. Like they they're

completely

amazed.

Because on the CT scan, obviously the

left lung is still gone.

But the right lung,

the disease is probably 60 70% gone. And

he he's still alive.

He goes home. There's no sign of the

disease after after treatment. And he he

uh I I just she just uh communicated

with me to tell me that he just got his

Make-A-Wish

uh thing for for his cancer. He's

continuing treatment.

And to And she just can't believe that

he was literally two day two days away

from dying.

They changed nothing. They changed none

of his treatments. The only thing that

they did was they took him outside and

they they were using this Firefly before

inside, but they were using it more

consistently when he got outside.

Maybe hospitals should be outside.

>> This is exactly what

Okay, so if you wanted to know what my

drive was, what what it is my purpose

that I'm doing right now, I'm working at

three different hospitals. And

I'm trying to work in each of those

three different hospitals to try to get

patients outside. The biggest barrier

that we have is staff taking those

patients outside. That's the thing

that's the hardest. But this is what we

used to do.

Steven, this is what we used

When we built hospitals at the turn of

the century, we had hospital rooms where

beds could be taken out onto the veranda

and people could get sunlight. I would

love to see a time where we could go

back to that type of effect. There are

studies that have been done. People in a

two-bed room,

if you're the bed closer to the window,

you get discharged from the hospital

faster, on average.

Really? Yes.

I need to swap sides of the bed with my

girlfriend.

She's on the sunny side.

>> There There's so much evidence for this.

People who are in hospitals that are

have bigger windows, they give better

surveys.

And hospitals

reimbursement is tied

to the surveys that they get from

patients. So, it's literally a

win-win-win. If hospitals started to, I

believe, get patients outside. And And

they're already doing this. There

I don't want to say that this isn't

happening. There are hospitals that are

have programs to get patients outside.

Um I think we just ought to be doing it

a lot more.

Um

temperance. Temperance? What does that

mean?

>> It's an old term, isn't it? It really

means

moderation. And And I I would say in

this sense, temperance really means to

avoid toxins in the body.

Um As somebody who is a pulmonologist,

who is What's a pulmonologist?

>> is someone who takes care of the lungs.

And so, as a result of that, I see a lot

of issues with lung cancer

related to smoking.

Um I see it in the intensive care unit,

people with liver failure as result of

alcohol abuse. I also see people

on amphetamines. Here in Southern

California, where I reside and where I

work, we we have quite a bit of that.

And uh temperance, if if you want to

live a long and wholesome life, there

are some toxins that you want to avoid.

And uh And And And understanding that is

really important. So, this is something

that, if you stop some of those things

that we're talking about, all of those

links are going to be improved.

Air.

Seems kind of obvious. Early on I used

to think that that what this meant was

getting pure air with absolutely nothing

in it except for just nitrogen and

oxygen.

That's not true anymore.

We now understand that for you to have

the best type of air,

it actually has to come with some things

in it. Just like our our gut has a

microflora that you may have heard

about, so too does the air that we

breathe also must have that. And the

best type of air that you can have is

actually outside.

Rest.

This is really interesting because we

just mentioned that exercise was a

pillar, but rest also is. How can rest

and exercise at the same time be pillars

of health? And it really comes down to

knowing when to do what. Sleep, which is

also part of rest. So we're not just

talking about a daily rest when you go

to sleep. And and as a sleep physician I

can tell you quite a bit. We have lots

of information about how long we should

sleep, the quality of sleep, some of the

diseases that prevent us from sleeping.

Sleep is so important. I can't I I

couldn't over express it enough. Not

just a a daily rest, but I would also

say and and venture out we can talk more

about this, a weekly rest. A weekly

rest?

>> A weekly rest.

What do you mean weekend? Yeah. Yeah,

absolutely. How many times do we even on

the weekend do we put down our our

phone? Never. Or we stop reading emails.

And we take the time out to do things

that we would never be able to do.

Finally, trust.

So this is something that really just

can't be ignored. And and I'll say this

up front that um

in the world of research and science

there is a there is a silo of science

and there is a silo of faith. But,

what's what we can't ignore is the

growing body of evidence

from the scientific world that's peeking

over and looking at faith, that people

who have faith and people who have faith

in God,

uh whether that is uh their God in in

that particular denomination, are better

apt and able to deal with stress and

depression and anxiety.

So, this is something scientifically

that has been shown. Now,

if you you may have noticed that I I did

these in a particular order.

Um and if you go through them, you've

got nutrition,

you've got exercise, you've got water,

you've got sunlight, you've got

temperance, you have air, you have rest,

and finally you have trust. You put that

together and it spells out NEWSTART.

So, interestingly, these these

particular topics are not copyrighted,

but there is a um there is a university

in Northern California called Weimar

University that has actually put these

together in that very pattern as called

it NEWSTART. They actually have a

NEWSTART program.

Um and so, this is something that uh

that is actually being used uh

internationally.

So, of these subjects that you just went

through there for this NEWSTART um

framework,

where do you want to start?

I think actually sunlight is is one of

those things where I'm excited about all

of those, but I think sunlight is

is really where we have It's the Let's

put it this way, it's the lowest-hanging

fruit. Okay. Explain to me why sunlight

is the the place where your focus is at

the moment.

It's a long trip that has gotten me to

that. Um and I and I think part of it

has to has goes through right through

COVID.

So, as a critical care intensivist, when

I heard that there was this virus that

was coming, they all told us that it was

going to be people with respiratory

illnesses, which I was certainly

comfortable with.

But, that's not what it turned out to

be. We certainly saw people with

respiratory illnesses, but what we saw

in the intensive care unit, the people

that were dying around me

were people with obesity, people with

heart disease, people with kidney

disease, people with dementia, people

with chronic diseases.

And it made me think, why was that the

case?

All of those things

have one thing in common.

And many other things, too. But,

specifically, they're rooted in

something called mitochondrial

dysfunction. So, let me unpack that for

you.

And and this has to do with longevity,

this has to do with aging. This is a

huge topic that is now just emerging.

And we're we're now finding more about

this. So, what when we were when I was

in high school biology, when I was in

college, uh we all learned about this

little organelle in all of our cells,

except for red blood cells, called the

mitochondria. And and and I have to say

it, what is the mitochondria? It's the

powerhouse of the cell, right? So, it's

the thing that makes energy.

What we didn't know at the time is that

as we get older, the output from these

batteries in our cells drops by about

70%. Damn. Can you imagine running your

house on 70% less energy? Well, how

fundamentally that would change what

change what happens in your house? Like,

you could not run the laundry the same

way. You could not run the microwave and

the laundry at the same time.

>> And what does that look like in terms of

symptoms? Excellent question, because

what it looks like is depending on the

cell type that we're talking about,

that's going to have the issue. So, if

we're talking about the liver, the

liver's going to get more fatty. If

we're talking about the heart, the

heart's going to is going to become more

congested. If we're talking about the

brain, it's going to have more dementia.

And so, what's what's happening here is

that as we get older, the batteries in

our cells are not working the same way

as they used to. Metabolism is slowing

down.

And and so, these are these are huge

issues.

And all of these diseases that I just

talked about, all the ones that we saw

in COVID, if you look in a lot of these

diseases, they are rooted in

mitochondrial dysfunction. So, the

question is is why is that the case and

what can we do about it?

So, there was a paper that came out in

2019

that fundamentally changed the way I saw

this. It was written by Russell Reiter

who is the

executive editor of melatonin research.

It's a he's out of University of Texas.

And Scott Zimmerman who's a light

engineer. And what they set forth was to

show that basically

sunlight

is

made up of so many different types of

wavelengths. You've got ultraviolet on

one end which of course makes vitamin D.

And it's very beneficial. It it it's the

type of light from the from the sun that

is very short wave

and but cannot penetrate very deeply.

Let let me let me back up a little bit

and explain.

You pull up to a stop sign and somebody

pulls up next to you and they're playing

the latest hip-hop music. How does that

sound to you in your car?

It's very boom boom, right?

>> Yeah, muffled. It muffled. And the

reason why is because low wave frequency

has the ability to travel very far.

Go to the Grand Canyon and there's a

thunderstorm at the other end of it.

What do you hear? It's like a rumbling.

And then as it gets closer, you hear the

higher pitched sounds. This is a

fundamental physics

principle. And so when the sun is is

shining, there's very short wavelengths,

ultraviolet B involved in vitamin D. But

at the other end, there's this infrared

light which we'll talk about or red

light. It's very long wavelength and it

can penetrate very very deeply.

That's very important because what we're

talking about is the human body. And if

the sun is going to have an effect on

the human body, it's got to be more than

just the skin.

So, that's exactly what what this paper

showed is that basically

infrared lights

from the sun

is able to penetrate probably up to

about 8 cm according to Scott Zimmerman

in this article.

And it fundamentally interacts with

specifically the mitochondria.

And what does it do to the mitochondria?

So let's let's back up and talk about

the mitochondria cuz this is central.

The mitochondria to the cell is like the

engine in your car.

The engine produces locomotion that

causes this the wheels to spin. But in

the process of doing it

it causes heat to surround the engine.

And if you don't deal with that heat

it will shut down the engine. It will

make it more inefficient and eventually

it will shut it down. So what do all

internal combustion engines have? They

have a cooling system. They have a

radiator. They have a an oil pan. They

have a water pump. And that's exactly

what the cell has to have for the

mitochondria. It's not heat in the

mitochondria. It's called oxidative

stress. And it's specifically oxidative

stress that causes destruction and

and yeah, destruction of the

mitochondria and leads to these types of

diseases. So oxidative stress causes the

mitochondria not to work well. This

leads to diabetes. Oxidative stress

makes the mitochondria not work so well.

This leads to dementia. So there's a

This has already been laid out. This is

not that controversial. The

controversial part is what do we do

about it? So what these guys in this

paper showed

was that and and not just them but look

reviewing the literature is that the

mitochondria makes its own cooling

system.

And that cooling system is melatonin.

Now you might think be thinking, wait a

minute, melatonin, isn't that the isn't

that the stuff that we take that our

brain makes right before we go to sleep?

Yeah, that you're it's absolutely

correct. That's what happens.

The problem is is that this is not

melatonin that's made in the brain. This

is not melatonin that goes through the

blood supply and goes to It through our

blood and tells us it's time to go to

sleep. This is melatonin that's made in

the cell in the mitochondria.

And it's a powerful antioxidant that

basically prevents the oxidative stress

from occurring.

What Scott Zimmerman and Russell Reiter

showed and and proposed in this was that

basically the infrared radiation that's

coming in

to the body is able to stimulate and

upregulate melatonin and a number of

other factors that keep the mitochondria

cool and can actually improve the energy

output of the mitochondria.

So this is This was actually

mind-blowing to me and I'll tell you why

I resonated with this as a critical care

physician because there was two things

that bothered me the most. Number one.

SARS-CoV-2 virus. When it comes into the

body, it interacts with something called

the ACE2 receptor. You may have heard

about the ACE2 receptor. Okay. This is

where the the virus actually latches on

to the cell

and gets internalized. So what is this

ACE2 receptor? Is this Was this there

for all of humanity just to be a

receptor or does it actually have a

role?

It turns out it actually has a role and

mind-blowingly

the ACE2 receptor is involved in

mitigating oxidative stress.

So in other words, it's another part of

the cell's cooling system for the

mitochondria.

What

what's happening is that the

the virus when it attaches to the cell

is basically eliminating that action.

And so

imagine you have a bunch of people with

various different engines running at

different temperatures. In other words,

you've got some people with chronic

disease and we know their engines are

running hot. We have some other people

who are completely healthy and they're

doing quite well. Their engines are nice

and cool. They have no problems at all.

Now imagine COVID comes and SARS-CoV-2

is infecting everybody.

What that tendency is to do is because

it's knocking out everybody's ACE2

receptor, which has the ability to cool

down the engine if in other words, it's

causing everybody's engine to run hot.

Right? So, but in somebody So, in other

words, picture it this way. You're

You're You're driving along in your car

and your thermometer is there and all of

a sudden there's this big hill that you

have to climb, called COVID-19. Who's

going to make it over that hill and

who's not going to make it over that

hill?

The people that make it over the hill

are those with great cooling engines

that whose temperatures are running

great. The ones that don't make it over

that hill are the ones that have the

thermometer on their engine running hot.

Those are the ones that poop out at the

top and can't make it and they're

they're the ones pulled over to the side

of the road with the hood up and the

steam coming out of the out of the

engine. Do you understand what I'm

saying?

>> yeah. So, this makes perfect sense to me

why I wasn't seeing what they were

predicting, which is respiratory

patients coming into the ICU. Who was I

seeing in the ICU? I was seeing people

with dementias, as we talked about,

diabetes, kidney disease. These are the

ones that were that that were sick. The

other thing that that really hit me

and resonated with this

was and this was this was not even

controversial. We knew early on in the

pandemic that people who came into the

hospital and had higher levels of

vitamin D

did really well.

They didn't die.

They They didn't have the same chances

of dying. People who had low vitamin D

levels, they had much higher levels

chances of dying.

So, we would check these vitamin D

levels. And so,

think about this. You're You're there at

ground zero and you're taking care of

these patients and you see this data

over and over and over again that

vitamin D is very predictive of who's

going to die. Obviously, what are you

going to do? Even though this is an

associative study, that association

doesn't mean causation, you're going to

be giving people vitamin D

and try to get those levels up.

The problem is is that we gave vitamin D

and it really didn't have much of an

effect.

So, you gave it in supplement tablets.

>> Yeah, when people would come into the

hospital exactly.

Exactly, just like that. In fact, I was

supplementing myself. I mean, what have

you got to lose, right?

I already took my vitamin D tablet this

morning. I don't There's not There's

very hard to overdose, but it's

possible. So, you noticed that it was

hard to treat people with vitamin D, but

giving them a a tablet didn't really do

much. That's correct. Why?

Well, this is what I believe is the is

the is the fact is we saw that people

with high levels of vitamin D or normal

levels of vitamin D did better than

those that had low levels. I believe

that that was a marker of something

else.

In other words, people who had higher

levels of vitamin D meant

that they were out in the sun more. They

were outside more.

Than those the people that had very low

vitamin D levels. The people with low

vitamin D levels were telling me these

are people that were not getting outside

into the sun. And so, what's the real

factor here? What's doing the heavy

lifting? And I would propose and Scott

Zimmerman and Russell Reiter would

propose, and I can tell you a number of

other scientists that would agree with

me on this,

is that infrared radiation

from the sun

is causing an effect at the

mitochondrial level in terms of

oxidative stress.

And that vitamin D was just the marker

of who was getting the infrared light

and who was not. Who was going outside

and who was not going outside. So, when

the sun is shining for the most part,

you're getting infrared light. You're

getting the entire the entire biological

spectrum from the sun. We can go to the

longest wavelength, which is far

infrared,

all the way to the shortest wavelength,

which is ultraviolet B, okay, which

makes vitamin D.

So, in other words, when you are outside

in a natural environment, you're getting

a very broad spectrum of light.

And so, because of that, if you're

getting infrared light, you're also

going to be making vitamin D.

Yeah, you're getting both.

Um

Now, that can change because in the

wintertime

when the sun is lower in the sky,

especially, you know, in England, this

is this is a special issue at that

latitude. When the sun is low in the

sky, it's got the light has to penetrate

through obliquely through the

atmosphere. And because of that,

shortwave

radiation from the sun, like ultraviolet

B, does not make it very well. So,

there's times of the year where you're

not getting enough ultraviolet B or

maybe even no ultraviolet B from the

sun. Which makes the vitamin D. Which

makes the vitamin D. And that you're

you're going to be deficient, you need

to supplement. However,

during that same period of time

when you're not getting enough vitamin D

because there's no ultraviolet B

radiation, that sun is low, but that's

it's still enough to allow that long

wavelength penetrating infrared light to

still come through. So, is the longwave

infrared light the type of thing that we

see

these gadgets doing? Absolutely. And and

I would say just to be specific is

because you can see that as red light

there, that's not infrared light because

you can see it.

So, infrared light technically is

completely invisible. But this these do

give out infrared light, but you just

can't see it.

>> So, it's toward that red end of the

spectrum. And people like Glen Jeffery

out of UCL

is actually doing research at 670

nanometers of red light and has shown

in randomized controlled trials that

that type of light right there at 670,

the type that you can even see,

actually does improve mitochondrial

efficiency. He's shown this in a number

of randomized controlled trials. It

improves eyesight. And and you have to

realize that the retina at the back of

your eye is very rich in mitochondria.

He's shown this in terms of managing

glucose and and output for mitochondria.

And and the reason why these things work

so well is because what's going on here

is as you get older, your skin starts to

become more saggy because the the

fibroblast or the cells in your skin,

they're designed to make collagen and

collagen is the skeleton that makes your

skin soft and subtle. Yeah. Don't mind

me. Please carry

>> No, no. So this is this is exactly My

wife uses the same thing. This is a fun

charge one day.

>> So what what's going on right now is

that red light

which can penetrate very deeply down is

going into the skin and it is activating

the mitochondria in your fibroblast to

produce more energy which those cells

need to deposit collagen. And so when

you deposit collagen, that's going to

give the skin a more tight uh feel

because as you get older, that collagen

deposition is going to get less and less

and less.

>> So this is going to help keep me looking

young. That's the whole point of it. And

you're saying that the the light in

these penetrates what, 6 or 7 cm or is

it

>> does about 8 cm. Uh this red light would

be a little bit less because this

light obviously you can see it, so it is

a little bit shorter wavelength, but

yes, this light, the red light can

penetrate deeper than for instance

yellow light or blue light. And it's

this light particularly that interacts

with the mitochondria to increase that.

So should we be putting this all over

our body because okay, it's good for my

skin, but if it's penetrating deeper,

presumably those other parts of my body

that would benefit from that, another

mitochondria. It's interesting you say

that. Um the the the study that I'm

referring to with Glenn Jeffery out of

University College London, he took uh

young people in this study. He gave them

a a bunch of glucose. And everybody who

gets a bunch of glucose should have a

spike in their blood sugar.

And he randomized them on their backs

to see what would happen when he shined

red lights uh on their backs. And the

people that got the red light had lower

spikes. In other words, it seemed as

though the mitochondria

were metabolizing faster, which caused

less of a spike of the glucose in their

blood. The way he confirmed that is

looking for the byproducts of the

mitochondrial metabolism, which is

carbon dioxide. So, when we breathe,

when we metabolize, we're breathing out

carbon dioxide, which is the result of

of a mitochondrial metabolism. And in

fact, in those people that had the light

on,

it showed a higher level of carbon

dioxide in the exhaled breath. The whole

point of that is to get back to your

question is whether we should putting

this all over your body. He was able to

get that effect systemically with just

putting the light on the back.

Um that was a that was a systemic

ability. What We don't understand

everything about the mitochondria, but

what we do seem to understand is that

they can communicate with each other.

And that you don't need to have this all

over the body to have systemic effects.

In this particular case though, if you

want to have the skin here to be more

you know, younger-looking, then it makes

sense that this is where you need to

have it. If you want to have a

particular other part of your body to

look younger, then then perhaps that

that's where the light needs to go. So

interesting. So how long did it take in

those studies to see the effect of red

light therapy like this? Well, that's a

very good question. If you talk to Glenn

Jeffery, which I have, he noticed a an

improvement in 15 minutes.

15 15 minutes? What did he notice in 15

minutes? He said he has studied the

mitochondria in fruit flies and in

mosquitoes and bees and in human beings

and it's the same every time. He says

after about 15 to 20 minutes of this

type of light in that type of setting,

there is a switch

that turns on and it and you and you

don't need further stimulation. Further

stimulation doesn't do anything more.

It's a it's a very bizarre thing. You

would think that the more light that you

gave, the more the effect would be. It's

not. After about 15 minutes, it it

there's something that changes in the

mitochondria.

There are certain theories about where

this might be. This might be in the

electron transport chain

complex four. Uh these are very

technical things. There's a lot of

studies that are actually There's a

number of groups that are actually

looking at this.

Uh there's a whole area of science

called photobiomodulation, which is

looking at this. But, 15 minutes is

really what it takes. So, we're not

we're not talking about a long period of

time.

This is really really interesting. So,

getting back to my

experience in the intensive care unit.

The vitamin D wasn't working.

These patients were dying, and it became

clear to me that COVID was a metabolic

issue

for these patients.

By the time I had realized this,

the sir I mean, the pandemic arguably is

still going on because people are still

becoming infected, but the rush to come

into the hospital and the and the number

of bodies that we were seeing

circulating through the intensive care

unit had dropped dramatically.

And at that point, I was able to

see that potentially

infrared lights may be very beneficial

in these patients with COVID-19. Now,

there was a study in Brazil. They took

COVID patients

that were that were sick enough to be

admitted to the hospital, but not too

sick to be intubated in intensive care

unit.

And they did something tremendous. They

actually manufactured a jacket that they

could put on patients. And on the inside

of this jacket were these LED bulbs that

gave off

infrared radiation at exactly 940

nanometers. They put the jackets on,

and they randomly randomized assign

which jacket was turned on and which

jacket was turned off. It was blinded

because the light coming from this

jacket could not be seen by the human

eye. It wasn't even enough to produce

enough heat.

And so they they did this on 30 subjects

and they randomized them. 15 did it 50

50 all 15 had or all 30 had the jackets

on. 15 had it turned on, 15 did not have

it turned on. And they watched them.

What happens to these patients?

Every single endpoint that they looked

at was statistically significant.

And What does that mean?

>> It means that the differences between

these two groups could not have been

from chance.

There was a real difference.

The group that had the jacket turned on

had improvement in their oxygen

saturation.

Had could take breaths in more deeply

and stronger. Had improvements in their

blood white blood cells.

Um and not only that, had improvements

in their heart rate, their respiratory

rate, all of these statistically

significant. But the most important and

mind-blowing statistic was the length of

stay in the hospital.

So,

they had these jackets on

for 15 minutes

once a day

for 7 days.

In the group that did not have the

jacket turned on, their average length

of stay was 12 days in the hospital.

For those that had the jacket turned on,

it was eight days. That was four day

difference. That's tremendous when you

realize that it costs thousands of

dollars

to hospitalize patients.

It's it's a huge amount when you think

about the fact that there are certain

drugs that get FDA approved for

influenza for instance by just cutting

short the symptoms for 24 hours. This is

not just 24 hours for people were

discharged

from the hospital four days faster. When

I saw that study, that was enough for me

to convince me. I mean obviously it was

30 subjects, right? We should do a

bigger study. We should do a hundred a

couple hundred, right? That would be

that would be ideal to do. But the fact

that with just 30 patients they could

show statistical significance. That was

enough for me to say every patient from

now on that I see

that comes in with COVID-19 that's

hospitalized, that they're asking me to

go intubate, to bring to my ICU, these

patients are going to get outside.

I don't have that jacket that they made

in Brazil.

I I I don't even know how I would make

that jacket. They made it for the study.

And it's not commercially available.

There's no 940 nanometer lights, which

is what they did in the study. But I do

know this. I do know that sunlight has

940 nanometers in it.

And if I could just take these patients

outside

maybe they could improve. So I had I got

my wish.

I had a patient on the floor.

He was on 35 liters a minute.

100% oxygen through high flow. Through

his nose. Through his nose. Barely

barely saturating because he had

COVID-19.

And uh I was asked to go see him because

he was potentially needing to be

intubated or brought to the intensive

care unit. I could not believe it cuz I

had not seen one of these in months. So

I went down, walked into the room,

opened the door. It was in isolation. I

had a mask on, the whole nine yards. The

room was completely dark. The blind was

closed. His daughter was there. And the

first words out of his mouth to me was

"Doc, how much time have I got?"

I mean, it was a catastrophe. Like

there's no light, no circadian rhythm.

This guy was depressed.

I immediately called my respiratory

therapist, immediately called the charge

nurse. We got everybody together. And I

said, "We need to get this guy outside."

It was a bright and sunny day.

How are we going to get this guy

outside? 35 liters, 100%. We My

respiratory therapist, Kim, managed to

put a couple of oxygen tanks together.

And we were able to get this guy into a

wheelchair.

And we wheeled him outside.

And uh he told me this uh weeks later.

But he says, "You know, that first day

that you got me outside in the sun cuz

we did this for like 7 days in a row.

He said, "That felt so good."

Um he after just 1 day dropped down from

35 L to 15 L.

15 L of of oxygen. And then down to 12,

and then down to 8 the next day, and

then down to 5. 5 days The amount of

oxygen he was inhaling to keep him

alive. Correct. So, in other words, we

were titrating down the amount of oxygen

that we had to give him to maintain a

saturation in the 90s. In 5 days he was

discharged home without oxygen.

Now, obviously that's an anecdote,

right? That's not a study. But, I'm

looking at the risks of getting people

out in the sun for 15-20 minutes.

There's not a lot of risk to that. And

if there's a benefit, I thought it was

worthwhile doing. We we need to have

larger randomized controlled trials, but

it got me down the road to looking to

see what what was it

about sunlight

that was affecting this change. And you

know what? There was There's There's

ample data.

There There was a study actually that

was done

in in Europe where they looked They

said, "Okay, here's COVID. COVID's going

up. When does COVID go up? Is it because

of temperature that changes? Is it

because of humidity?" And the answers to

both of those were no. Do you know what

predicted when countries were to have

their first surge in the autumn of 2020?

There was a study that was actually done

on this.

It was latitude.

It started in Finland

and then real it went down the entire

continent. The last country in the in

the autumn of 2020 to have a COVID surge

was Greece.

So, as the sun is literally pulling down

into the southern hemisphere, as the

shadow starts to go over Europe, that's

when we start to see

COVID surges one by one by one. There

was Yeah. Is that Is that because COVID

and the sun aren't friends? So, if I it

makes it harder to spread because, you

know, if I put COVID on this table and

then I put sunlight on the table, the

COVID is going to die. Yeah, it's

possible. Although we now know that

COVID probably doesn't spread too much

through contact. It's it's more of an

airborne thing. So there there was a

study that was done at the University of

Edinburgh.

And they looked at this very question

that we had talked about earlier about

vitamin D. They looked at the United

States in the in the wintertime.

So and they eliminated the southern part

of the United States because in the

southern part of the United States you

can actually get some vitamin D in the

wintertime. So they just looked at the

sort of the northern portion of the

United States and they were able to show

that the more sunlight there was in

particular areas, the lower the

mortality from COVID-19.

So they said, "Well, this is

interesting.

What about in England?" So they they did

the exact same study in England and and

sure enough of course they didn't have

to eliminate any part of England because

the whole country doesn't get in any

vitamin D in the wintertime. What they

showed was that again, certain parts of

the country in England as you know, get

more sunlight than other parts. Well,

those areas that got more sunlight had

lower

mortality from COVID-19. Then they took

the same

They predicated the same study and they

looked in Italy.

Exactly the same finding and they

published this. And they said in their

study and this is what really amazed me.

They said,

"The fact if this is causal,

they say." They said that

this might actually show a possible

public health intervention. The fact

that it is completely independent of

vitamin D means that there's something

else going on.

There was a study in 2011 in Sweden.

Yes.

Is that linked to this?

>> No, this is a completely different

study. But that that's also a very

important study. So the Swedish study is

is is groundbreaking. Um

This was a study where they asked 20,000

20 to 30,000 Swedish women

about their habits in sunlight.

And they divided these women into three

categories. Those women that did not get

a lot of sun, those that got a moderate

amount of sun, and those that got a lot

of sun. And they followed them for 20

years. And they they kept a track of

each one that died and what they died

of.

And when they were done with that, they

were astonished because what they found

was that

the women who had spent most spent the

large amount of their time outside or

that spent the most amount of time

outside

had

the least amount of mortality from

cancer,

from cardiovascular disease, and

non-cardiovascular disease. And those

that spent the least amount of time

outside had the highest levels of that.

The magnitude difference between those

two was so much

that they were able to show that women

who in Sweden

who spent the most amount of time

outside and smoked

had the same mortality as those women

that did not spend as much time outside

and did not smoke.

They were equal. They were equal. In

other words,

being in that category of not spending

much time outside in the sun was the

same risk factor for death as smoking.

How do they know it wasn't linked to

exercise? How are they able to establish

causation cuz that's a You're absolutely

That's an excellent question. So, the

the difference here as you go up is this

is a this is an association study, okay?

So, the question is is how can you get

causation from association? You can't.

But, if you look at the Bradford Hill

criteria, there is a way that you can

potentially make a a strong argument for

causation if there's something called a

dose-response curve. In other words, if

you can show you're not just comparing

two things, but you're comparing three

or more, if you can show that as you

increase

the variable, that there is a change in

the

the outputs that is strongly suggestive

of potentially causation. By the way,

this is exactly what we did to show that

smoking causes lung cancer. Obviously,

we can't do a randomized control trial

here. You get to smoke, you don't get to

smoke. We'll follow up in 20 years to

see who has lung cancer. This is exactly

what we did. We showed that that there

was such a strong association with

cancer risk with smoking that we were

able to say through association that

smoking causes lung cancer. By the way,

Richard Weller

was a dermatologist in England uh did

just last year a very similar study as

to the Swedish study except it was 10

times bigger

and he did it with both men and women.

He found the same results.

It was a UK Biobank study.

What did he discover? He discovered that

either from

from solariums or from um or being

outside using solar radiation data

uh he was able to show both on their

their questionnaire and also where they

lived

that the more light that they had the

lower their risk as of of um mortality

uh and um and cancer mortality. So, the

question was

does it increase melanoma?

What's melanoma? Melanoma is is a skin

cancer. So, that's the big risk. That's

the big risk that everybody's concerned

about. You go out into the sun sun and

you're going to get skin cancer.

And he was able to show in that study

this was like three three 400,000 people

in this study. UK Biobank study, Richard

Weller.

He was able to show that

there was no increased there's no

statistical increased risk of melanoma

incidence but there was

a reduction in non-skin cancer

mortality.

Okay, so so here's the trade-off. If you

want to go out into the sun in England

okay?

The benefits are you're going to have a

reduction

in non-skin cancer mortality. So,

everything other than skin cancer?

>> Correct.

On the other hand, there's no increase

in melanoma incidence. So, that caused

him to write an a an op-ed and publish

it. And actually, you can look up this

op-ed. It's a great op-ed. Uh it

published in a um

in the Journal of Investigative

Dermatology called Sunlight: Time for a

Rethink. Where he goes through the

arguments. And he's actually shown And

there's been a number of changes that

people have making around the globe. So,

public health uh

organizations that are saying now, you

know, before we have said

that, you know, the the sun is a deadly

laser.

And you should avoid it at all costs.

We may need to rethink that.

So, you telling me that essentially 15

minutes in the sun every day turns on a

switch in my body that improves my

mitochondrial function, which is going

to impact a variety of different parts

of my health. Is that essentially what

you're saying? Essentially, yes. Uh and

and we're we're looking And this is in

an environment where where we are

spending less and less and less time.

To give To give you To put in

perspective, if we were on a British

ship 300 years ago, and I came to you

and I said, "Do you see this little

yellow fruit? Just by eating a little

bit of this yellow fruit, all of this

disease that you're seeing around you

with your fellow shipmates is going to

go away." That that would seem almost

incredulous, right? But, that's exactly

the case.

We We are

The scurvy of the 21st century is the

lack of sunlight.

Everything is inside.

Uh we we avoid the outside. We avoid

discomfort. We avoid high temperatures.

We avoid low temperatures. We uh are We

used to go out and play sports. We now

are are playing virtual sports on on

pads.

We have windows

that are specifically designed,

especially here here Southern

California, to eliminate infrared

lights. Because why? Infrared lights

comes in and it heats up. One of the

interesting things we didn't mention

this about infrared light is the way

that we interact with infrared light.

You can You can tell this on your own.

You go outside

and

close your eyes. You can tell which side

of your body the sun is on. And the

reason is is because that infrared light

not only can penetrate through your

body, it's also penetrating through

clothes

very easily.

And you can feel that. That That heat

that you're feeling is the infrared

light going through this going through

the clothes, going through the skin, and

interacting with your heat receptors

that are well below the surface.

How long does the average American spend

indoors? Does the average Brit spend

indoors? Good question. They're almost

identical. I think the Brits spend a

little bit more time outside than

Americans. The The last number for

Americans was 93%

and uh Brits is 92%.

>> Were we born to be outside? I think so.

You think our ancestors probably spent a

huge amount of time outside? Yeah. And

And And if you think about when I say

outside, that also brings into play a

number of other of the new start letters

that we haven't talked about. Uh

exercise. You're much more likely to do

good exercise outside. You're much more

likely to get air that's that's the

right type of air outside.

The other aspect about infrared light,

briefly,

is that trees

are highly reflective of infrared light.

In other words, if you're in an

environment where there are trees are

present, you're going to get much more

of this beneficial infrared light than

if you're in a concrete jungle.

So So So plants like this. In fact, the

way that we measure the deforestation of

the Amazon is through satellite imaging

that looks at infrared light because it

reflects infrared light back. So,

the best thing best situation to be in

is to be outside

on a green

on a day where where there's lots of

green trees. We've known for We've known

for decades that people who live in

green spaces

do much better in terms of diabetes, do

much better in terms of hypertension,

mortality, all of these things.

>> Depression. Depression, all of these

things, yeah.

And And when you think about this, um

you bring up a point in terms of of

correlation. How do we know it's not

depression? We used to say, "Well,

people who live in green spaces have

more money."

that people have They have more access

to things. Maybe that's what we're

saying.

I just have to tell you this study.

There was something called the

GreenHeart study in South Louisville,

Kentucky. They did an amazing thing.

They took this 4-square-mile area

in South Louisville, Kentucky, urbanized

area.

And they measured everybody's hs-CRP.

What is hs-CRP? Highly sensitive

C-reactive protein. It's a marker of

inflammation, and it's been correlated

to bad things like stroke and heart

attack. So, if you have high levels of

CRP, that's not good.

So, they measured every They measured

about 700 people.

And then they did something

extraordinary. They purchased 8,000

mature trees,

dug holes, and planted 8,000 trees into

4-square-mile area. And these are trees

with leaves on them.

2 years later, they come back and they

measure all 700 people in their study.

Repeat the hs-CRP.

Dropped by 13 to 20%, which correlated

to about a 10 to 15% reduction in

strokes.

These people didn't change their

socioeconomic status. They didn't

institute an exercise program. And so,

really, it kind of shoots in the heart

the idea that the advantage that we see

with green spaces has to do with

something else that we're not measuring.

I actually believe that we'll talk about

fresh air, too, that things like

these plants,

but much bigger. This is kind of like a

bonsai plant. But But trees outside,

they actually have a benefit. And what

they represent, again, is

these things that

don't leverage the other parts of your

body in the in terms of the chains uh

that make all of the chains bigger cuz

they're they're they're they're having a

benefit. But you can't get the benefit

of this if you're inside a house. So,

what should we do about this in terms of

how what changes should I make in my

life to capitalize on this? Um this is a

This brand here is called Bon Charge.

They do these Yeah. these red light

devices. They do like red light saunas,

blankets, um masks. They're actually a

sponsor of mine because I I started

wearing this and I think they they found

out. And I started wearing it because of

my girlfriend. Yeah. She was wearing it

every day and I got curious. And so, I

as I always do, I'm always super

skeptical. Sure. So, I went on online

and started looking at some of the

research. And I was shocked. Yeah.

>> It made no intuitive sense to me that a

red light mask or any like red light

device could have a profound like what I

see is a profound impact on my health.

Like I didn't believe it Yes.

>> to start with. Yes.

>> like woo-woo stuff to me. I I Yeah.

>> But I couldn't disprove it. Right. All

the studies, many of which you've

referenced, um supported that it was

having a profound impact. And as I said

on this podcast before, my girlfriend's

always right.

She's like always ahead of the curve and

always right. So, I started wearing her

mask and now I have my own from Bon

Charge.

>> Yeah. Ish. Do you recommend these kinds

of things? I I think it's reasonable to

do. I will say this. Um if you are

getting enough infrared light from the

sun,

what we find in studies, not

particularly with the mask, but we find

in other things, is that these these

other areas don't have as much efficacy.

It's almost to say, if you're on a ship

with a bunch of people with scurvy and

you already have a diet that's rich in

vegetables and fruits, eating an extra

lemon is not going to be that

beneficial. So, what do you do? Like a

lot of doctors do, we have shifts that

go from 7:00 a.m. to the p.m. So, you're

in the hospital, you're not going to get

outside. So, at lunch, I try to get

outside as much as I possibly can into

the sun for my 15 minutes.

>> What if you live in a cloudy country?

So, that's a good point. Uh clouds,

because they are water molecules, will

absorb a lot of the infrared lights. And

the problem is is that that's the

exactly the type of light that you want

to get. However, even on a cloudy day,

being outside, you're going to get more

infrared lights than if you were inside.

Okay, so I still get the light I need

when it's cloudy, but I just don't get a

lot.

Yes, exactly.

>> Is there anything I can do to get if

it's super cloudy and I know I'm going

to be indoors,

what do I do then? Yeah. So, the light

the type of lights that we have inside,

like these ones? Like these. Uh and and

and actually, I think the UK and the

United States are very similar in this

regard, is that we really can't get the

old incandescent bulbs. We're on LED or

or fluorescent. And if you think about

what they've done in terms of of these

bulbs,

the old incandescent bulbs used to give

you a very broad uh

spectrum. So, all the way from, you

know, just near blue all the way down

into the into the infrared. The way that

they've made the bulbs more efficient,

they said, "Hey, let's stop using energy

to give off this light that we can't see

and give a very narrow spectrum of light

that we can see."

So, think about what they've done. They

have for the first time in the history

of humanity,

they are now we are now being exposed to

light

in a very narrow spectrum without

anything else. Whatever in the history

of of humankind, when we light a candle,

when we would go outside into the

sunlight, when we would have a kerosene

lamp,

we were getting full spectrum.

In other words, we were never getting

blue lights without red lights. Now,

we're starting to get blue light without

red light.

So So do I change my bulbs?

It's difficult to do that because you

can't pick up in these incandescent

bulbs. Which brings me to I mean at

least at least in the United States, we

have laws now that outlaw the regular

selling of incandescent bulbs because of

energy efficiency. Oh yeah. I'm on

Google now and I've typed in

incandescent bulb. So there's something

called a general service lamp, which is

what the type of bulbs that you could

plug in. But if you decide that you want

to get a

bulb that you put into your microwave or

a bulb that you would do into a type of

chandelier that's a special type of

chandelier, those are still available.

You can still get incandescent bulbs for

those. What about these kinds of bulbs?

Is that an incandescent bulb? That's a

That is a That is an incandescent bulb.

Again, for these special type of lights,

but I'm I'm talking about the light like

the like the the good old fashioned A90,

I think it's called, light bulb that you

just screw in.

Those are

the 120 watts, those are getting more

difficult. You It's harder to find. You

can't go down to your Home Depot and and

find them there. So Glenn Jeffrey um and

this is this is a preprint that he is

he's done. He actually took

people

with that were working in this

environment with LED bulbs. He's

actually It's not peer-reviewed, it's

not published yet, but it's a preprint,

it's available on the internet, so I'm

not speaking out of class.

And what he did with 22 people is he

switched out

these LED bulbs and put in incandescent

bulbs.

And there was a there was a 25%

improvement in in color differentiation

in his study.

What does that mean? They were able to

distinguish colors 25% better than they

were when they were exposed to LED LED

When I say LED bulbs, these are the

bulbs that are high on the blue end.

Um so why would that be?

The retina, which is the back of your

eye, where in the light is coming in,

there's these cones that are

tremendously metabolically active.

They're constantly updating, sending

neural signals to the brain.

And there's It's the It's the one tissue

in your body with the most amount of

mitochondria. And it's because they have

to supply a lot of energy. As somebody

gets older,

that mitochondria is not producing the

same amount of energy. And so, the the

ability of the energy that those cones

have to draw on to do their work is

less. And so, they're not going to do

the job as well.

If you can perhaps increase the

the

the amount of output of energy from

those mitochondria, you could improve

the the the ability to visually

perceive. And and and

Glenn Jeffery has done this study

already, where he

for just 3 minutes,

670 nanometer light, very similar to

that mask, in the eye, only in the

morning,

improved

those people's ability to to to to

visualize and actually see.

And what does that mean for the broader

picture of our health?

>> would be able to distinguish colors

better and actually improve their

vision.

That's basically what it means.

Um and so, the question goes back to the

first question that you had at the very

beginning of the podcast, which is what

is the effect of low

energy output from the mitochondria.

Well, it depends on what tissue the

mitochondria is in. And so, if it's in

the eye,

then it's going to be a bit better

visual perception. If it's in the brain,

it's dementia. If it's You know, you see

You see what I'm saying? So, what we

start to see
