Welcome to the Huberman Lab podcast where we discuss science and science-based tools for everyday life.
I'm Andrew Huberman and I'm a professor of neurobiology and
Optomology at Stanford School of Medicine.
Recently, I had the pleasure of hosting two live events, one in Seattle, Washington and one in Portland, Oregon, both entitled the Brain Body Contract where I discussed
Science and Science-related tools for mental health, physical health, and performance.
My favorite part of each evening, however,
was the question and answer period
that followed the lecture.
I love the question and answer period
because it gives me an opportunity here directly
from the audience to what they want to know most.
And indeed to get into a bit of dialogue,
so we really clarify what are the underlying mechanisms
of particular tools, how best to use the tools
for things like focus and sleep.
We also touch on some things related to mental health and physical health.
It was a delight for me and I like to think that the audience learned a lot.
I know that many of you weren't able to attend those events, but we wanted to make the
information available to you.
Therefore, what follows this is a recording of the question and answer period from the
lecture in Portland, Oregon.
I hope you'll find it to be both interesting and informative.
I'd also like to thank our sponsors of these live events,
the first is Momentus Supplements,
which is our partner with the Hubertman Lab podcast,
providing supplements that are of the very highest quality
that ship on international,
and that are arranged in dosages and single ingredient
formulations that make it possible
for you to develop the optimal supplement strategy for you.
And I'd also like to thank our other sponsor, which is Inside Tracker, which provides blood
tests and DNA tests, so you can monitor your immediate and long-term health progress.
I'd also like to announce that there are two new live events scheduled.
The first one is going to take place Sunday, October 16th at the Wheelturn Theater in Los
Angeles.
The other live event will take place Wednesday, November 9th at the Beacon Theater in New York City.
Tickets to both of those events are now available online at HubermanLab.com slash tour.
That's HubermanLab.com slash tour. I do hope that you learn from and enjoy the recording of
the Question and Answer period that follows this. And last but certainly not least, thank you for your interest in science.
What are the current best practices for post-TBI's traumatic brain injuries for those of you
that aren't familiar with TBI, especially long-term multiple OU, et cetera, thoughts on hyperbaric.
Oh, I'm so glad you asked this, Danny Morlage, as treatment for TBI's.
Okay, TBI, one thing about TBI and concussion, everyone thinks football.
Guess what?
Most of the TBI is not football.
There aren't that many football players.
They're just large, so they stand out.
There might be a few here this evening.
Of course football players are a concern when it comes to TBI. Most head injuries are going to be construction workers. Have you ever seen the hard hats they wear? I don't even know if they
are just there for show. It doesn't make sense.
And we actually have a lab at Stanford that's focused very hard on trying to solve this problem.
So construction workers, car accidents, bicycle accidents, Portland, amazing city to cycle.
I'm frankly afraid to cycle.
You're a small moving object around these big objects and people are staring to their
little aperture on their phone while driving.
I mean, whatever happened to that, by the way, of not texting while driving.
Somehow that just disappeared.
It's like, it really has just disappeared.
There was all this science showing that it's worse than drunk driving it.
TBI. Well, the basic rules of the don't apply, if you get a head injury, don't get a second
head injury. But that often isn't feasible for people that, you know, need to work, continue
work in construction, or that are struggling. What do we know? Well, this is a great opportunity for me to distinguish
modulatory foundational tools from things that directly change your brain
in a nervous system the way that you want to. What do I mean by modulatory?
We hear so much and there's so many studies showing that great sleep,
quality nutrition, good social interactions, avoiding chronic stress,
and on and on and on are important for everything.
Reduce, they're related to Alzheimer's,
they're related to ADHD.
I mean, we could do thousands of podcast episodes,
just returning to the same 10 things.
Sleep, don't stress too much or too long,
good social connection, avoid toxic people.
Eat good food, not too much processed food.
We could have an argument all night
and I don't want to have one about whether or not
it's mainly plants or this.
I mean, on the internet, this is, you know,
obviously eating high quality food
is something that we shall be doing.
Which foods you select is a topic that is very barbed wire
and I can give only my opinions.
All of that modulates your brain function,
but it doesn't mediate or change anything directly.
It's setting a foundation of what's possible.
So we should all be doing those things
and especially people who have TBI.
Now, this question relates to hyperbaric chamber.
Hyperbaric chamber, there's very interesting data.
It's essentially a hyperoxygenation of the brain
for very brief periods of time.
I think the data on hyperbaric chamber and TBI are very encouraging.
The problem is much in the way that a few years ago, cryo was only available in a few
places and now people are doing ice baths and cold showers on their own, it's hard to
find a hyperbaric chamber.
They aren't just laying around and they don't have them at spas typically and they are
quite expensive.
So yes, they are interesting and important data,
I think, on hyperbaric chamber.
You definitely wanna work with a physician,
or somebody who is very skilled, a practitioner
who's very skilled in hyperbaric chamber,
they do seem to improve brain function by
hyperoxagène the brain for periods of time.
Seems to improve a number of things,
but above all, it seems to improve the quality and duration
of sleep, which indirectly allows the brain to repair itself, because as I mentioned earlier,
brain repair occurs, or brain change largely occurs in sleep. So if you don't have access
to hyperbaric chamber, but you do have TBI, what are some of the other data? What are those
point two? Well, I go on and on and you don't have to get this from supplements, you can get it from
food, but this threshold level of essential, these EPA essential fatty acids, there are
now so many data, so much data on the valuable role of these essential EPA fatty acids, thresholds
being somewhere between one and two grams per day of the EPA. So much so, actually, that there are now prescription forms
of EPA that doctors are starting to prescribe
for people with TBI.
Although for most people, you can look up,
and we've done podcast episodes about different ways
to access this.
Also, functions as an antidepressant, equally good,
believe it or not, in clinical trials to SSRIs.
Once one gets over the one or basically two grams per day of the EPA.
The resident expert on the internet about this is pretty extreme about the dosages, and
that's Dr. Ron Napatric, who by the way deserves a nod of acknowledgement and support, because
it turns out that before me or Davidson Claire or Matt Walker,
any of these guys were blabbing to the world about stuff that they had learned
in the archives of science and in their laboratories.
The first person in was this woman named Rhonda Patrick.
As far as I know, the first public facing formally trained scientists
to start going on all these podcasts and risks, cur deputation,
and this kind of stuff that you deal with when you put your neck out there like that. And Ronda's,
I think, terrific. We don't agree on everything and they would be weird if we did. But I think
she's really been the proponent of these higher doses of EPAs for TBI and for cognitive function
into all ages. We often hear about ways to increase dopamine, however,
are there effective ways to decrease dopamine
when you get too much of it for certain behaviors
or habits we wanna break?
Katie, I think is the last name.
Thank you, Katie, for your question.
Yeah, dopamine is a slippery slope.
And Dr. Anilempki is the expert in this
and we've had a lot of conversations.
She's one of my closer friends on the faculty.
Unfortunately for her, our coffee discussions often
last four hours or more, her poor patients and family.
Here's the thing.
When dopamine is higher in your brain and body,
when you've deployed it through excitement
or pharmacology or otherwise, it tends to narrow your focus and make you seek more of
it in that general theme that you happen to be focused on. Could be anything.
That's the scary thing about dopamine. What can you do to control it and to reduce
it? Well, for those of you that are engaging in habits that are healthy, maybe that doesn't
require reducing dopamine, how do you define healthy versus unhealthy?
Well, I think the simplest way to define addiction, at least by my mind, is that addiction
is a progressive narrowing of the things that bring you pleasure, and a good life is a
progressive expansion of the things that bring you pleasure.
A rather simple definition, and yet when we think about the biology of dopamine,
dopamine is not unique to one pursuit.
It's not unique to pursuit, the pursuit of sex,
or the pursuit of warmth when you're cold, or cool environments when you're too warm,
or food, or social media.
It's just a dumb molecule that puts you into this forward state of mass,
small visual aperture, and a kind of obsessive-like nature.
What can you do to counter that?
Well, the best thing to do is to not get into that state too long, but if you do, the
best thing you can do is to try and switch off that system not through pharmacology, but
by not pursuing more dopamine.
The day after a big event, the so-called postpartum depression,
named of course, because of true postpartum
after the delivery of a child that's quite common
for people to get very, very depressed,
there's a lot of neurochemical and hormonal adjustments
that are occurring, but different types
of postpartum depression occur after a big party,
the Monday blues, the Monday blues,
the Sunday blues, the post-whatever blues, the four-month mark in a relationship
is typically when dopamine starts to drop. I always tell people, just wait, I'm
telling somebody very close to me right now, just wait four months, four months,
four months, and also spend as much time with that person as possible.
I don't know what this deal is about not spending as much time with people.
I think people are afraid that the dopamine wave pool is just going to pull them both under.
I think they call that the escalator model of relationship where you just sort of find
yourself in the relationship because you went through the stages without actually deciding
on them in any event.
Four months seems to be the stage in which the dopamine crescendo starts to relax a little bit, not in a long-distance relationship, however.
We know this, right?
Anticipation is dopamine, that positive anticipation.
And there's a whole beautiful science of this, and I should say psychology of this.
There's a wonderful book actually.
The name of the book is embarrassing always.
I don't know why for me to say it's a,
by a psychologist called Kin Love Last,
which is a psychoanalytic book about this dopamine
serotonin system and the kind of sea-sawing back and forth.
And the fact that in relationships people often just slam
on the dopamine side of things, and then they hit a wall
and want to break up, where they go into this like warm, cozy, fuzzy feeling thing and they go, well, I guess the exciting
part is over and this idea that one could actually, or two people, or however many people
were in Portland, could oscillate this seesaw.
I don't think that you want to use pharmacology to turn off the dopamine system, but for people
that have a hard time sleeping and that are really in a state of agitation and constantly
obsessing, the psychiatrist, one of the oldest and most effective treatments, is that the
psychiatrist, and this does have to be prescribed, we'll use a very, very low dose of a dopamine
receptor blocker, like Haloparital, which is a used to a very, very low dose of a dopamine receptor blocker, like Halopyr at all, which is a used to treat schizophrenia, very low dose to shut
down the obsession component. Smart, well-educated psychiatrists know this as a
useful tool, but this is a one-time thing with a very low dose because having
your dopamine block sucks. It does not feel good, but not being able to sleep and
being in obsessive mode also sucks.
So it's actually a very potent clinical tool.
So pharmacology is one tool, but really at the far end
of things I believe that one should try
and modulate their own dopamine by not rewarding oneself
on a regular basis, but only randomly. Random intermittent reward is truly the best schedule
of reward, hence slot machines, and so on.
And you should engage random intermittent reward.
And I think this is also the way that we should train kids.
Ascent, I call it training kids.
You can tell I don't have kids.
The, you don't reward them every time.
I don't believe everyone should get a trophy every time, nor should you always just reward
the winners because those winners often, we see cases of this, high profile cases of this,
they often crash and burn.
I mean, the number of high performers that crash and burn publicly, and Lord knows how many
do it privately, is remarkable, it's because their dopamine system is all messed up. So random intermittent reward is the schedule reward
that we should impart on ourselves.
If you had 10 minutes a day to improve your brain
plus this, what would you do and when would you do it?
Richard Conlon, thank you.
Well, I'm gonna say again,
I would absolutely anchor my physiology with morning sunlight viewing.
I can't help it.
You know what's interesting?
I'll tell you very briefly.
You know what's special about morning sunlight, this low-wing solar angle sunlight.
I don't think I've talked about this much on social media or on the podcast.
There's a group at the University of Washington, a couple, Jay and Moring Knights.
They run a lab together.
That sounds like a horrible thing, but they do it and they get along very well.
They've discovered that the cells in your eye, the neurons that set your circadian clock,
make you alert during the day and make you sleepy at night and so on.
Those cells respond best to yellow, blue contrast and orange tones.
Now, this is important because when you go out in the morning,
even if it's not at sunrise, but it's close to sunrise,
or you look at the sun in the evening,
what you'll see is yellow blue contrast or orange, yellow,
blue, orange, that old thing from kindergarten or first grade.
That's not the color of light that you're going to see
when the sun is overhead.
Now, this also is really interesting
because artificial lights, at least to my understanding,
even the daylight simulators have not picked up on this.
It's just about bright light.
Someone ought to design something that can mimic this,
but nature has done this beautifully for us.
And so viewing low solar angle sunlight in the morning and in the evening is most effective
because of those yellow blue contrasts.
Now here's the really wild thing.
Those circuits that set your levels of alertness and sleep, yes, they respond best to yellow
blue contrast.
But what that tells us is crazy.
What that means is that color vision
was probably not related to color perception first, because all of that is completely subconscious.
The pathways that do this are present in people
who are pattern vision blind.
So what do I mean?
I mean that color vision likely evolved
from a need to synchronize your internal state
with the external world,
and the best stimulus in the outside world to do that is yellow, blue contrast.
In other words, our ability to detect color was first and foremost.
And we understand this based on evolutionary genomics and so forth.
To extract time of day information, not color of fruit or color of skin or anything like
that.
That's all secondary, which is wild and crazy.
And this is yet another example of the way we think things work is not the way they work.
It's completely 180 degrees opposite.
I'm just going to be a little teaser.
I had a guest on the podcast.
He hasn't, we haven't aired the episode yet.
His name is Eric Jarvis.
He works on speech and language.
He also was admitted into Alvin Aley Dance Company.
Again, who are these people?
He's a professor at the Rockefeller.
Anyway, I learned from Eric and you'll learn
when that episode comes out that you only find
elaborate speech and language in species
that also engage in dance and song.
And the genomics point to the fact that song and singing
came first and language came second.
And that led me during that episode of the podcast I wrote down in my notes.
I was listening to him talk and I wrote down in my notebook.
It's just scrawled in big letters.
It says, I am so happy right now.
I was just blown away.
And it makes so much sense when you hear it that the colors in the sky or what we, our system is trying to extract,
not a perception of those colors in the sky
because they're informing us about time
and orienting us in time.
That song and the communication of emotional states
would be simpler and more foundational
than communication about specific patterns of language.
When you hear it, suddenly it makes sense,
but of course we're human beings
and unless you're Eric Jarvis or Ali Krom
or Analemki, you think about all this stuff backwards
as I do.
How can I navigate my way through taking supplements
to optimize my health when my career demands
are infantry, prevent me from being able
to establish consistent routines.
Andrew Yegan, well thank you for doing what you do.
Andrew, so the consistent routine thing is tough. routines. Andriyagan will thank you for doing what you do. Andrew.
So the consistent routine thing is tough.
Here's what I can say without going into a long two and a half hour episode about jet
lag and shift work, which we've done.
The most powerful way to anchor your brain and body in time is indeed viewing light, sunlight
at consistent
times of day.
That's not something I made up.
We know this based on a lot of work that dates back to the 1930s.
The second most powerful stimulus is going to be movement and changes in body temperature
and particular increases in body temperature tend to make us alert and decreases in body
temperature and to make us sleepy. Body temperature drops one to three degrees to make us alert, and decreases in body temperature and to make us sleepy.
Body temperature drops one to three degrees
to get us into sleep.
Why does a cold shower wake you up?
Adrenaline is released and believe it or not,
your body is heating up internally
to combat that cold,
unless you make yourself hypothermic.
So sauna hot baths to get sleepy,
cold showers, ice baths, et cetera, to wake up.
Sort of obvious when you hear it, but it's counterintuitive
because you think, oh, heating up the body to wake up
and cooling down the body to go to sleep,
so getting into cold oughta cool me down.
But your body compensates just like if you threw a cold towel
on a thermostat, you crank up the temperature in the room
and vice versa for heat.
Okay.
So what do you do?
You want to try and use as many of these things, light,
temperature, exercise, food, when you eat. It's typically associated with waking. Very few of us
are capable of eating in our sleep. And then the other one is social activity and rhythms. Now the
discombobulated person is going to be the person that has not aligned to these things in a consistent
way. So while schedule is very, and indirect, don't know your exact schedule, what I can say is,
if you suddenly go from daytime behavior and sleeping at night to the so-called vampire
shift as it's called in the military, and suddenly you're up in the middle of the night
and you're sleeping during the day, then when you come off that shift, what you want to
do is try and combine as many of those same things
at one time.
So it would be, get your sunlight, so go jogging
without your sunglasses, drink your coffee,
engage with other people, and communicate,
eat a meal afterwards, or as the case may be before.
Try and bring as many of those things together
the same time of day for a few days,
and pretty soon your system will map around that.
So the reason I encourage for those of us that are not doing shift work to try and be
fairly consistent about sunlight viewing is it sets in motion everything else that's
correct, but if in terms of timing of eating, appetite will follow, when your alert will
follow, you'll start to learn your own rhythms. When you can't control your schedule, try and combine as many of those cues, again,
light, temperature, exercise, food, social engagement into one period of time and try and
lock that into a more or less a one or two hour period, or plus or minus one or two hours
at a particular time of day for at least two or three days.
And your schedule,
meaning your internal clocks will lock to that.
How is social media changing our brains?
Thomas, add it.
Well, you know, you hear all the terrible ways
in which it's changing our brains.
And I think that, again, we go back to this thing
is it the aperture that we're looking at?
So is it the format that we're engaging in things?
Or is it the content? Well, engaging in things, or is it the content?
Well, the way I like to think about the phone
is the way that we've been engaging with the phone
and the laptop, for that matter,
in staring into the small visual aperture each day,
is sort of like walking like this all day long, right?
We have this amazing ability to shuffle our feet
and take small steps, or to take big strides
to run to move, I think that's the sagittal plane for movement, I know it for the brain,
but it always messes.
The PT's are vicious people online, by the way.
The PT's and nutrition people, I've learned to just not say anything about that I'm not
a PT and I'm not a physical therapist, and they do incredible work, but it's a very
spirited crowd.
And the nutrition thing is really weird,
how I mean, it's just incredible.
You're either people are either throwing liver at you
or they're throwing celery at you
or they're fasting or they're not fasting, it's nuts.
In any case, the social media and staring at a small visual aperture is changing our brains.
Here's one way I know in which is changing our brains and then I'll tell you how to fix
it.
If you stare or look at something within two feet of you for a certain number of hours
each day, your eyeball actually gets longer.
And the visual image then is focused in front of your neural retina, not onto your neural
retina, and you are becoming myopic, near-sighted.
And if you look at things in the distance enough, guess what?
Your eyeball changes shape, and your lens will focus appropriately, the image onto your retina,
take some work.
Kids that look at things up close too much work. Kids that look at things up close too much
and adults that look at things up close much
become near-sighted.
And there's a beautiful set of clinical trials now
where mainly in kids, if kids get outside
for two hours a day, getting a lot of this UVB
and blue light that we're told is so terrible for us,
but they get it from sunlight,
they actually can reverse myopia,
reduce the incidence of myopia, maybe even glaucoma,
although that's a big maybe.
So how much staring into a small visual aperture is too much?
I don't know, but what we do know is that we are literally
becoming myopic in terms of our vision
and we're becoming myopic in terms of our cognition.
And then there's the whole business of what's actually contained in those tweets and those
social media feeds and those news stories, which frankly, I feel like you lose either way,
whether or not you're in one political camp or another political camp, you're upset
about half of the information out there.
So I feel like it's, you know, I'm not a, not someone who knows how to talk about politics
without stumbling.
I didn't do well in social studies
and this sort of thing.
It just never made sense to me.
It just felt like the prize goes to the person
who can shout the loudest and the most
coherently for a moment.
So, but I encourage, of course, people
to be politically active.
And I vote.
But the content is tricky to navigate,
and I can't really speak to that,
except that it seems to be bothering everybody
on one side or the other or in the middle.
And the format is something that we really understand.
And again, I don't know of many people
that are talking about this narrow visual window format thing. It came up more during the lockdowns when we were all inside
a lot and not looking out at a distance. The data say really to try and get at least
10 minutes of long distance viewing, so longer than 10 feet away from us, for every 30 minutes
of close-up viewing and not a lot of us are doing that. If you're walking to your car looking at your phone,
you're definitely losing an opportunity.
What new piece of neurological research are you most excited about?
Mateo Manado.
I think the piece of neurological research that, all right,
the weird stuff, I've got this
colleague at Stanford, Tony Weiss-Korey, and they're really into literally taking proteins
from young blood and young spinal cord cerebral spinal fluid and putting it into older people
and animals and they get younger.
That stuff's pretty wild.
The fecal transplant stuff is pretty wild, right?
You take the microbiome from one person and as it sounds,
you transplant it to somebody else and they take on the
physical characteristics of the donor. It's crazy.
Until I talk to my gun, there's some shouts for fecal transplant.
Nice. I have never read the method sections of those papers.
I'm actually afraid to read the methods sections of those papers. I'm actually afraid to read
the methods sections. I would say this is not neurological, but the work from Chris Gardner
and Justin Saunenberg also at Stanford makes it sound like I just like Stanford's
here. But these are the people I'm close to and surrounded by. There are excellent places
everywhere, of course, including OHSU, and I'm not just saying that because I'm here, actually,
of close colleagues here and friends here at OHSU.
Also amazing, although that tram thing freaks me out, I always just have all these ideas
about what's going to happen if that thing breaks.
But the microbiome data are really interesting.
I never understood why getting your gut microbiome was important, and it turns out it's because
your gut actually makes many of the neurotransmitter precursors that your brain uses.
So that's pretty cool.
And I always thought it would be a complicated thing to get your gut microbiome right, but
it turns out that it's fermented foods that seem to have the biggest effect.
There was all this argument about fiber and yes, fiber is important.
And here I'm getting nervous talking about nutrition
because the people are going to like come at me with fiber.
But the, but it's very clear from Justin and Chris's data
that people who are getting four servings a day
of these fermented foods, whether or not it's kimchi
or sour, crowd or kombucha, all that.
That stuff actually seems to encourage a healthy gut microbiome.
And people feel better in their immune system works better.
And I like this because it actually, it resolves an issue,
which is that high dose probiotics,
these very expensive need to be refrigerated things.
Those actually can create brain fog and other issues.
They're for real severe cases of dysbiosis.
So I always like an instance where one can look to foods
which are good because I like to eat in order to resolve
these issues.
In terms of other neurologic issues,
I think that frankly, I think the stuff on dopamine
is fundamentally important.
So much addiction, that's a severe case,
but also so much waxing and waning of
Motivation and once you understand the dopamine system and you say what activities am I engaging in or pharmacology am I engaging in? What am I doing to spike dopamine? You start to go oh I get it the waves in this wave pool are too high
And that's why I can't do this consistently and then you do the counterintuitive thing of
Approaching things with a little less excitement
But then you're able counterintuitive thing of approaching things with a little less excitement,
but then you're able to do them more consistently.
It's like, ah, and maybe with some luck
I'll end up finishing this book
that I've been working on for four and a half years
as a consequence, because I can't seem to.
Thinking about the Wim Hof method, do you believe it?
How is it really working?
What process is happening in his brain?
Oh boy.
Madison Cameron, everyone here probably familiar with Vroomhof, whose occupation on Wikipedia
used to be Daredevil.
That was cool.
It's like Evil, Can Evil Had it, and Vroom Had it.
I got a story about Vroom actually in 2016.
I heard about this guy Vroomhof, and I got a hold of him, actually his children.
And I had one vacation that year and I flew to Spain
and I spent some time mountaineering with Wim,
which was absolutely terrifying.
I almost lost a leg legitimately.
I tied in wrong on a bridge sling.
He told me it was good for me.
He told me to stare into the lizard's eyes told me to stare into the lizard's eyes.
And I stared into the lizard's eyes.
I jumped backwards off this homemade bridge sling thing.
And I had the rope wrapped through my leg
and I came back with basically the tendon on the back
of my knee exposed.
And sitting next to me on the plane
was our vice dean of research at Stanford. And I had to explain to him what I was doing and why.
It was very embarrassing.
What did we do on that trip?
Well, a couple of things that will help me answer your question.
First of all, when I arrived, I suffered terribly from jet lag.
But the moment I got there, Wim did not say hello.
He literally told me to get into the ice bath.
And I did 10 minutes in the ice bath, not because I'm tough, He literally told me to get into the ice bath.
And I did 10 minutes in the ice bath,
not because I'm tough, but because he held me
down in the ice bath.
He is indeed one of the strongest human beings.
He reminds me of the bus driver on the Simpsons,
or the janitor, excuse me,
no, Otto is the bus driver, right?
That the janitor on the Simpsons,
like, ooh, that guy, that's Wim,
incredibly physically strong guy.
What do I think's going on with Wim Hof stuff?
Well, Wim Hof, whether or not he understands it or not,
I always think he's sort of the Bob Dylan of breathwork.
Like everything he says seems to have some intuitive sense,
but you don't really understand what in the world he's saying.
He's gonna come after me now.
We've had a good but complicated
relationship. I'll just confess, maybe someday we'll resolve that. No big scandal or story
there, just we communicate very differently.
WIM has a couple methods. One is to deliberately hyperventilate. There's also called Tumbo breathing.
My lab actually studies this. We have a paper that I'm happy to share with you
the results so that they're not published yet.
Where people do deliberate cyclic hyperventilation,
which as the name suggests, you just breathe really deeply
in and really deeply out 25 times.
Or if you're whim, you say, you know, no, no, no.
I just tell people, here's how it works.
You go, you do that 25 times and you heat up
and you feel really agitated.
And that's because of adrenaline.
If you throw yourself into an ice bath or a cold shower, adrenaline.
If somebody upsets you or you get a triggering text, adrenaline.
Adrenaline sounds like a terrible thing except when you deliberately induce it, as my colleague David Spiegel says,
there's a big difference between going into a state and you controlling your entry into a state.
So it's not just about the state you're in,
it's about how you got there
and whether or not you had anything to do with it.
States of high adrenaline are very powerful.
When you self-induce adrenaline by cold shower,
cyclic hyperventilation,
aka Wim Hof breathing, or tummo breathing,
you then have an opportunity
to create a very distinct mind-body relationship.
We all hear that interoception and the mind-body relationship and interoception just your ability
to sense your heartbeats and what's going on in your body, powerful, right?
Terrible if you, how you feel sucks.
So interoception is wonderful, but when you're anxious, it actually is a more adaptive to be able to maintain your thinking and get yourself out of that anxious state.
So if you're trembling and your body is freaking a lot, where you've experienced a lot of trauma
or typically this is people that have been barred with extreme criticism or physical abuse
or other kinds of abuse during development, they actually can seem very calm, but internally
they're freaking out in their head and they're just thinking, just get me through this
and they just go into a state where no one knows their upset.
I've known people like this and it's eerie to me because I've never had that response to stress,
but it's very common.
And so we should learn and be careful about deciding
that people are in one state or another
based on their bodily or their mental response.
Vimhoff breathing, cold showers, et cetera,
are a great practice, in my opinion,
because they allow you to spike your adrenaline and
you can do that, for instance, by making the water colder if you want more adrenaline,
staying in longer if you want more adrenaline, moving your limbs around in the water will
give you more adrenaline because it breaks up that thermal layer, it makes it a lot colder,
or doing 50 deep inhales and exhales.
That is very useful because then you have the opportunity
to use that prefrontal cortex and to stop
and sense all that adrenaline in your body
and yet maintain clarity of mind.
And that's an absolutely powerful tool.
I would even call it a power tool.
And Wim figured this out.
I don't know if you know this,
but the way that Wim discovered all this
was he was in deep grief
about the tragic death of his wife.
She committed suicide, jumped off an eight-story building,
just truly tragic death.
And he was in situation.
He had four children at the time.
Now he has five.
And he was in a state of depression,
and he ended up going into the canal in Amsterdam and it was very
cold and it shocked his system.
And in that shock to his system, which is caused by adrenaline, he somehow was able to
anchor his thinking and kind of genius of sorts.
When, wow, I can intervene in my physiology with this strange activity.
And then he realized that breathing would do it as well.
You didn't have to get into cold water.
And then years later, we discovered, not we meaning my lab,
but other labs that when you get into cold water,
even just 60 degree water, that there's a very long lasting increase
in dopamine, that is 2.5x above baseline, which is on par with some prescription drugs for
increasing dopamine.
So when people laugh at me, oh, this cold water thing, I get teased a lot on the internet.
I've heard on the internet that I eat sticks of butter, which I never said.
I said, I like butter.
I've been told all sorts of things.
I've been told I eat sticks of butter.
I was like, I don't know why. I've been told that I'm things. I've been told I eat sticks of butter. I was like, I don't know why.
I've been told that I'm dead.
That was an interesting one.
That was one of the cooler ones.
But when I was going out there as a serious scientist
and saying, using deliberate cold exposure,
you can use all sorts of things.
Or if you come to my lab, I'll be happy to put you in VR
and expose you all sorts of scary stuff.
Or we can inject you with adrenaline.
Or you can inject yourself with adrenaline and titrate that, adjust the
levels of that.
So, it's a very powerful tool, and I think that WIM and others deserve credit for really
tapping into that.
And as a last point, there's a beautiful study in the Prostings of the National Academy
of Sciences years ago using this deliberate cyclic hyperventilation thing, 25 reps. And then another group meditates, and then they inject them both with E. coli.
And the people injected with E. coli who meditate get nauseous, vomit, diarrhea, and they get a fever.
And the people who first, far fewer symptoms if any.
Why? Because adrenaline actually suppresses a lot of these innate
immune responses in a way that's healthy in the short term.
This is why you can work, work, work, work,
or you can study for finals,
and you can take care of a loved one,
and then you finally stop and rest
and go on vacation, and then you get sick.
Stress activates your nervous system,
and in doing so, it activates your immune system, makes perfect
sense when you think about it.
How would we ever go through famine if you're just getting flused whenever you're stressed?
We can deal with a lot.
My suggestion is if you're coming off a period of high stress to do some sort of adrenaline
spiking behavior as you taper out of that stressful period, not going strictly to massage
vacation and yoga needager all day long,
as I would reflexively do.
Can red light therapy help treat exercise intolerance
and fatigue and mitochondrial disease, Allison?
I'm glad you brought this up.
This is another case where I thought, oh no,
this red light stuff is crazy.
And then I went into the literature and turns out
that in 1908, the Nobel Prize was actually given
for phototherapy.
So there we go again.
And here, you know, I have this slide.
I chose not to use slides tonight, but I have this slide that shows Ken Kesey and the
magic boss and stuff from the 1930s and psychedelics and people getting into cold water.
And then here we are, 2019, 2020.
You've got Wimphoth and Matt Johnson giving people macrodosis of psilocybin.
We're right back where we were.
And one of my major goals is to really try and create some scientific discussion around
these things.
This stuff is crazy on the face of it, but there are mechanisms that are real that underlight.
Red light, because it's long wavelength light,
longer literally as opposed to short wavelength light, can penetrate through things like skin
and can indeed change mitochondria.
One of the more impressive results on red light
comes from my good friend Glen Jeffries lab
at the University of College London.
I'm known Glen for years.
In a few years, he was a basic vision scientist
and a few years ago he started using red light.
You'd have people look at red light at a distance of about two
feet in the morning.
So this is a long wavelength light.
And sometimes even just take a flashlight at torch, as they
call it, in England, and cover it with a red film.
And they would look at this stuff for a few minutes each
morning.
And it can reverse some forms of age-related vision loss
and macular degeneration. How we now know it can prove some forms of age-related vision loss and macular degeneration, how
we now know it can prove mitochondrial function in photoreceptors by reducing what are called
reactive oxygen species.
Here's what's interesting.
It only seems to work in people older than 40.
And it seems to only work if you do it within the first three hours of waking.
And the incredible thing is you can do this for one or two minutes a week and some of the positive effects last as long as three weeks.
And it's affecting a very specific form of visual improvement, which is acuity, kind
of fine detail stuff in my particular wavelength, so particular colors and objects and things.
Pretty impressive.
So yes, red light can improve my deconjural function to the photo receptors.
If you are going to try and do this stuff, don't put it too close.
I don't have any affiliation in a red light panel company,
so I can't say anything there.
They are rather expensive.
Nowadays, people are putting red light everywhere,
and I do mean everywhere.
People are putting red light on their stomach
for improving a variant function.
Whether or not I can penetrate is unclear to me.
All the way down there, people are trying to do this.
I have a friend, I won't name him.
Recently, he told me he's really into the red light therapy.
He's putting it on his testicles to try and increase testosterone.
But he told me that after he handed me the red light.
True story.
My team knows who this is, it's no one on my team.
They're gonna say, oh, that's super interesting. I actually don't think you want to contact the red lights
directly to your skin.
So red light is powerful.
I don't think we have, aside from the vision protocol,
I don't think that it's clear which protocols are best.
I will say if you're into red light infrared sauna,
typically those don't get hot enough.
Typically, if you want to get the benefits of sauna,
you want to get between 80 and 100 degrees Celsius,
which is 176 to 210 or 208 Fahrenheit,
and I don't actually do the conversion in my head.
I remember I said, you mentioned the consequences
of blasting your brain with too much dopamine.
Is it possible to overdo ice baths?
Well, following the same line of thinking,
will you experience extreme low and dopamine
with too many ice baths, Lucy Anke?
Thank you for the question.
Any behavior that spikes adrenaline,
you will eventually get better at tolerating it.
You will become cold-adapted,
and you will become comfortable at high adrenaline states.
And you just have to ask yourself this,
it's just like lifting weights in the gym or running.
You need to leave some space for improvement.
So if you run as people do and you do your half marathon, your 5K, then your 10K, then
your half marathon, maybe a 10K is a half marathon, I don't know.
But anyway, then you're doing your marathon, then you're doing ultras that are 50 miles
and 100 miles.
I mean, eventually you're going to start doing damage, right?
And eventually, you look at every ultra runner,
and typically these are people who are very much
on the dopamine pursuit system.
I mean, I don't think that he would mind my good friend
and a podcaster who I have tremendous respect for,
a rich role, amazing human being.
And also, it has an amazing story about addiction.
It was an alcoholic, I'm not sharing anything
that he hasn't already shared in this amazing book, Finding Ultra.
He got really into running, running, running all the time.
And there's a dopamine history there for him.
Some of us can use ice baths so consistently
and make it so cold and doing them longer and longer.
That, indeed, you're playing with the dopamine system.
Is it bad?
Well, it depends on what you're trading that in for, at the expense of what?
Is it giving up cocaine?
Yeah, great.
Stick with the ice bath.
But you can only make it so cold and you can only stay in there so long before you become
whim-hoff, right?
And it worked out for whim, but there's really only one of whim-hoff.
And in general, that speaks to a larger theme, which is I love the idea of people using tools
and understanding mechanism.
I mean, of course, I love that.
It's what I talk about and think about so much in my life.
But for most of us, we don't make a living doing those things.
And so I do think that the ideal situation is to have behaviors and tools that you interspers
throughout your day and throughout the week.
For instance, I think three times a week
is fine for the ice bath.
No one said you had to do it every day,
but you should see sunlight every morning, if you can.
Just because if you miss a day, your system will be fine
just spend twice as long outside the next day seriously,
because it's a slow, integrating system.
But for most of these high intensity things, the less often you do them, the more
powerful they are.
In fact, if you get into a very hot sauna for four, excuse me, 30 minute sessions on one
day, so you go 30 minutes, get out for five minutes, 30 minutes, get out for five minutes,
30 minutes, get out for five minutes, two hours a day in the sauna, that's a lot of
sauna. But the growth hormone released from that type of protocol
is a 16X increase in growth hormone.
This has been measured in humans, whereas if you do it every day
or three or four times a week, you get diminishing returns
on that.
So I actually am a big fan of doing really intense stuff
only every once in a while.
This is also why I only take one long run per week
or one long hike.
First of all, I don't have time for it.
I'm not an ultra runner.
I got other things to do.
And it's not going to fall.
It's a strong stimulus.
I'm sore until Tuesday, or I don't want to run until Tuesday,
anyway.
I actually think that's fine.
And I actually encourage that have more healthy,
rational schedules of these kinds of behaviors.
There's no rule that says you have to do something every day, even if you're trying to engage
general plasticity.
You can learn French or an instrument by practicing three times a week, as long as your practice
is very focused.
Daily perhaps would be better, but very few of us have the opportunity to do things every day consistently
and I really want to encourage a more balanced approach.
Before working through Fashore, what's the base?
Oh, goodness gracious.
The skateboarders are always in the house.
My first non-biological family was a skateboarding community when I, I, I, I've great relationship
with my parents now, but because there was a time when there was no one to go to soccer games or do any of that stuff, the skateboard
community took me in because there were no parents involved. It was great. There were
no referees or coaches because I didn't like authority and it was, it was awesome. And
there was no nutritional plan. You drank your slurpee and you sat on the curb and it was
fantastic. I don't do that anymore, but the skateboarding community is one that I've
remained close with.
I did write for Thrasher under a different name while I was a postdoc to make some extra
cash.
You won't find those articles anywhere, I hope.
They're not very good.
And that's the way I was involved in it enough that I, this only makes sense like three
people in the audience, but I had decent heel flip, I could gnawly better than I could all of you.
And I was never very good.
And I just, other more skateboarders in the audience.
What I will say though, is you have to be very careful
with skateboarders because I don't want to claim
that I was any good.
Any success that I had was out of sympathy of others
for letting me hang around.
It's a great community.
And it gave me great appreciation for, indeed,
communities of kids that don't have structure
and sports leagues and teams and all that kind of stuff.
Nowadays, it's actually a much different landscape
and I have to also say what it's really amazing
to see all the incredible girls and women's
skateboarders also, there were none.
It's a limpyx sport now for women and girls
and it's an Olympic sport for boys and men too.
So it's awesome to see that community.
What are your favorite brain hacks for doing hard things, ranging from cold exposure to getting through selection?
I'll be honest, I learned how to hack into my adrenaline system a long time ago through the worst possible mechanism,
which is that I would set up battles in my mind, I would get into competition with people imagined or real,
or I would get into states of fearing shame and, you know, screwing up. So I would, you can, this is what a lot of people do, I think.
You end up scaring yourself into trying to do the hard thing.
And it works.
The problem is it feels rather like a downward spiral,
because those negative states of mind
work to liberate adrenaline and get you in through hard things.
So being as a rebellious kid, resistance, if someone told me I couldn't do something,
I was like, yeah, try me.
Um, this kind of thing.
And I, as I mentioned before, I wasn't crazy about authority.
And so that was the method for a long time.
And then, then I started reading all of her sacks as books.
And I started learning from people who seem to access things
through this whole love thing.
And I tried that love and kindness meditation thing
and that didn't work.
And what I started doing was I actually,
I'll just tell you, when I, before I came out here tonight
and before I do anything challenging,
I just actually like to imagine the people
that have supported me.
It's a weird tool I don't think I've ever shared.
I'm actually slightly embarrassed to share this out.
Because there are only two things that make me cry
and that's talking about my bulldog
and talking about my graduate advisor.
And if I talk about any longer, I'll probably cry.
But I think about them a lot
because they were kind of similar.
They were kind of ordinary
and they were hard on me
and I adored them both.
And so these days I try and think about people
that really that I love.
And so I have been trying to do this whole
like doing things from a place of love thing.
And so for me that's animals and people that I love.
Okay, now I am better move on.
So, oh thank you.
Okay, they're telling me one more question.
So I'm going to answer one more.
What do I fear?
How do you manage your fear, KB?
Oh, gosh.
This is going to turn into a, no one's going to be satisfied
until I cry.
I get it.
I get it.
I do cry, but again about the things I mentioned before.
I realize something, by the way.
We just recorded an episode on grief.
It hasn't come out yet. Fascinating topic. I realize at one point, by the way. We just recorded an episode on grief. It hasn't come out yet.
Fascinating topic.
I realized at one point by the way,
I'll just give this away, that I thought I was really sad
about losing them.
I thought I would tear up really easily
because I was sad about them.
But then I realized, this gosh, I can't believe I'm gonna do this.
But I realized that feeling that I was feeling
is the exact same feeling of love that I had when they were alive.
So grief is love and when you look at the literature, it's basically that, but your brain is freaking out because that map of knowing where people are in space and time.
Grief is basically a remapping of the space. Where are they? Time. When are they?
And then this kind of abstract map representation that we call closeness.
And grief is this process of of ripping ourselves off of that.
So in any event, what do I fear talking about things like this?
What do I fear?
Quite honestly, my biggest fear,
the thing that would just make me feel just horrible
is I fear letting down my friends.
I have an amazing, I love my family and they're wonderful, but I have this incredible relationship
to friendship and I just I adore my friends and I would sooner give up all my limbs and
die before I would I would deliberately let them down.
So there you go, that's what I fear most.
Thank you.
Thank you.
Thank you.
I also fear I've gone long, and so my team has shut this down.
I just want to, just briefly, two things.
First of all, I, of course, want to thank everyone
for coming here tonight.
I realize it's the middle of the week
and to commit some hours of your life
to thinking about these brain mechanisms.
We got pretty nerdy there for a minute.
And hopefully the tools,
redeemed those who were only interested
or mostly interested in practical tools, but hopefully
some of the insights about how you work were useful as well.
I do want to just make brief mention of the sponsors that made this possible because
they did make this possible, and we made every effort to try and keep the ticket prices
manageable for people.
And thanks to Inside Tracker and Mementus for making this possible.
And then of course, I would be completely remiss if I
didn't say thank you for your interest in science. Thank you. Thank you. Thank you. Thank you. Thank you.
Thank you so much.
Everyone, be sure to get home safely tonight.
