00:00Welcome to the Huberman Lab podcast,

00:02where we discuss science and science-based tools

00:04for everyday life.

00:08I'm Andrew Huberman,

00:10and I'm a professor of neurobiology and ophthalmology

00:12at Stanford School of Medicine.

00:15Recently, the Huberman Lab hosted a live event

00:17at the Beacon Theater in New York City.

00:19The event was entitled The Brain-Body Contract,

00:22and it consisted of a lecture

00:24followed by a question and answer session with the audience.

00:27We wanted to make the recorded version

00:28of that question and answer session available to everybody,

00:31regardless of who could attend.

00:33So what follows is the question and answer period

00:36from the Brain Body Contract Live Huberman Lab event.

00:39I want to be sure to thank the sponsors from that event.

00:42They were Eight Sleep, which makes smart mattress covers

00:45with heating and cooling capacity.

00:47I started sleeping on an Eight Sleep mattress cover

00:49about eight months ago,

00:50and it has completely transformed my sleep.

00:52I sleep so much deeper.

00:54I wake up far less during the middle of the night,

00:56if at all, and I wake up feeling

00:58far better than I ever have,

01:00even after the same amount of sleep.

01:02In fact, I love my eight sleep so much

01:03that when I travel,

01:05now I'm quite bothered that Airbnbs

01:07and hotels don't have eight sleep mattress covers on them.

01:10And I've even shipped my eight sleep mattress cover

01:12out to meet me in the location that I arrived to

01:15so that I get the best possible sleep.

01:17If you want to try eight sleep,

01:18you can go to eightsleep.com slash Huberman

01:21to save up to $400 off their SleepFit Holiday Bundle,

01:24which includes their new pod three cover.

01:26Eight Sleep currently ships in the USA, Canada,

01:29United Kingdom, select countries in the EU and Australia.

01:32Again, that's eightsleep.com slash Huberman.

01:35I'd like to also thank our supplement partner, Momentus.

01:38They make the very highest quality supplements.

01:40They ship internationally

01:41and they've formulated supplements

01:44as single ingredient formulations

01:46that match what is discussed on the Huberman Lab podcast.

01:50If you're interested in any of those supplements,

01:52please go to livemomentus.com slash Huberman.

01:54And now, without further ado, the question and answer session from the live event held at the Beacon Theater in New York City.

02:01And as always, thank you for your interest in science.

02:17You've said before that stress can be good for us, but how do we know when it's too much?

02:21That's a good question.

02:22and I should preface that by saying that there's some incredible work that was done by a colleague

02:30of mine, Dr. Alia Crum, Ali is how she goes by, Dr. Ali Crum, who is a, she was a division one

02:39athlete. She has a, she's a tenured professor of psychology at Stanford. She's a licensed clinical

02:45psychologist. Like every once in a while I look around at my colleagues, I'm like, oh my goodness,

02:49who are these people. Very humbling place to be. But she's made some important discoveries,

02:54and I want to just highlight one, which is this notion of mindset. And no, these are not placebo

02:58effects, but let me just tell you, when you think about stress, how you think about stress is really

03:03important. First of all, you can't lie to yourself, but if, for instance, you watch a one or three

03:09minute video, as she's given subjects in her lab, about stress, and it tells you all the terrible

03:15things that stress does to your immune system in sleep, then you experience those things, increases

03:20in blood pressure, etc. However, if you watch a one to three minute video that's also true about

03:24the fact that stress can sharpen your decision making for certain kinds of things, actually can

03:29accentuate your immune system. I wish someone would help me get this narrative right out there.

03:33Stress does not deplete your immune system unless it goes on a long, long time. We'll talk about

03:37what long means in a moment. Why would it? Think about it. If you had to fast and move with family

03:45or weather a storm of any kind, emotional or physical, and you got sick, that wouldn't make

03:52any sense. It's usually after you're stressed. If you've ever been go, go, go, or taking care of a

03:56loved one or studying or working hard, and then you finally go on vacation, you rest, you arrive

04:00and you get sick, it's because your immune system shut down. It stopped. Your immune system is

04:05mobilized by that alertness side of your autonomic nervous system. But you do need sleep.

04:12You do need sleep. And it's actually, we think, the slowing of circulation. And this is why it's

04:17probably not a good idea to exercise if you're already sick. And if you're veering towards sick,

04:22probably limit the intensity of any kind of interaction as best you can and just still

04:26yourself. Well, Ali's lab has clearly shown us over and over again that what we know,

04:33our knowledge base really does shape the physiology over those outcomes. Now you know

04:37that stress is both bad and good. So which one is it? Does it average to nothing? No. It turns out

04:43that you can bias this in one direction or the other, depending on which information you're

04:49listening to more often. I think this is really important. You know, I still am trying to get my

04:54head and my mind around what's happened over the last few years and where it's placed us. Like,

05:00Where did it land us?

05:01Are we more resilient now?

05:02Or are we just really beat up?

05:04I don't know.

05:06I really don't know.

05:07But I think how we interpret the last few years is going to make a big difference in terms of how it impacts us.

05:13How do we know if we are...

05:16Thanks.

05:16Yeah, what we're missing out there, I think, is a narrative from somebody that people listen to.

05:22And I'm not saying that person should be me.

05:23In fact, it shouldn't be me.

05:25But somebody that can help us frame what's just happened to us.

05:29much like a good, I think that the world needs a good therapist, basically. It's a very good

05:33therapist. So I would call short-term stress, which is very beneficial for us, is the kind of

05:40stress that happens on the order of a day, two or three days. Not a problem, even if you feel torn

05:45apart, provided you can get rest afterwards. Long-term stress is the kind of stress that

05:49really starts to impede your sleep-wake cycle, make your dreams more stressful and more like

05:55nightmares and they're not going away. And I can promise you that for those of you that have

06:00challenges with sort of an accumulation of stress from the past that's now compounded by what's

06:06happening now, et cetera, that the solution does seem to be to get yourself into a supported

06:12environment of some kind that will allow you to go through a full catharsis. Again, it doesn't

06:17have to require psychedelics. That can take you through the full ride of autonomic intensity

06:24catharsis of some sort and then relaxation that does seem to be what snaps people out of

06:30what we would call longer term stress and historical stress there's even the question

06:35of whether or not focusing directly on the trauma and the story is so critical i think it is obviously

06:42that's something that should be done with a clinician but stress that impedes your sleep

06:48for three nights or more that shifts the pattern of dreams to more anxious dreams that is more

06:53long-term stress and for that you need to take it seriously and it's the kind of thing where

06:58if you don't take it seriously it can start degrading things like your immune system

07:03etc and I would say that under those conditions use sleep as a good marker in fact I'm sure

07:11there's some clinicians in the room I mean one of the questions that is used as a diagnostic

07:15for whether or not people are depressed or anxiously depressed is whether or not they're

07:20sleeping well or not right again language is not very good at parsing what's going on inside we

07:25have to look to behaviors and regularity of sleep wake cycles etc hopefully that was at least a

07:32partial answer I could I try to be accurate but if I were exhaustive I would I might actually cure

07:40insomnia someday with these podcasts the if nothing else how is hypnosis impacting my life

07:47I'm in hypnosis now. No, I actually spend most of the afternoon in hypnosis. Before I do these,

07:53I spend a good hour in hypnosis. Again, self-directed hypnosis. Gosh, it's so

07:58unfortunate. I keep talking to David Spiegel about this. Again, his dad was one of the

08:04originators of hypnosis as a valid psychiatric treatment. There's even the idea that things like

08:11EMDR, the scanning of eyes back and forth while reporting a narrative, may actually be capturing

08:15some of the elements of hypnosis. Again, and this is why, at least for me, I appreciate the

08:21opportunity to come together tonight to talk about principles. I would hope that after tonight,

08:25you could look at any practice, anything, any compound, any breathing exercise, and just be

08:31able to frame up which continuum, where on the continuum, what's it really designed to do, move

08:37you up towards alertness or down towards calm. And in fact, because I can't help myself, I'll just

08:42tell you for all the breathing stuff it can be made very simple if your exhales

08:46are longer and more vigorous than your inhales you're gonna get calmed down

08:50if your inhales are longer and more vigorous than your exhales you're going

08:55to become more alert if you hold your breath just eventually just start

08:58breathing again the physiology maps perfectly to that that maps

09:04perfectly to the physiology and if you for instance you do box breathing inhale

09:07hold exhale holding and this kind of thing well you're gonna stay right where

09:11at you're gonna be on an even plane more or less okay so that sort of hopefully

09:16captures all of breath work in one sentence now I'll answer the question

09:19you were asking me hypnosis it's impacted my life in a couple of ways

09:23one way is more from a practical scientific way which is that my

09:30laboratory works on vision and we work on stress and in some ways those might

09:35seem divorced although now with the cuttlefish and the fact that your eyes

09:39narrow their field of view when you're stressed, etc. It should become obvious why that is.

09:43But hypnosis also takes advantage of this really weird kind of cool feature, which is, and it's

09:49always weird when you do a group exercise, but I can't really see you all that well. I certainly

09:54can't see your eyes well enough to know this. But David Spiegel, there's actually something in the,

09:59this is a valid thing called the Spiegel eye roll test, and it's not the teenage eye roll,

10:04that when you look up while not moving your head,

10:08when you look up, you actually are engaging circuits in your brainstem

10:12that are involved in generating alertness.

10:15And when you look down and your eyes close, the opposite is true.

10:18You're engaging circuits in the brain that are taking you into a calmer state.

10:22Now, wouldn't it be wonderful if all you had to do was look down

10:24and you'd be calm and look up and you'd be alert?

10:26That doesn't quite work that way.

10:27But to induce hypnosis, what they do is they have people look up

10:30and then while looking up, close their eyes,

10:34which is actually kind of hard to do.

10:36Some people can't do it.

10:38Their eyes roll forward, hence the eye roll test.

10:41Some people, their eyes get, you see the whites of their eyes

10:44and it looks really spooky,

10:46and they're looking up while their eyes close.

10:47Those people are very prone to hypnosis.

10:50Why?

10:51Well, hypnosis is a state of deep relaxation

10:53with alertness and focus.

10:56It's a contextual narrowing.

10:58excuse me. So it's like being in early stage sleep and that's why stage hypnosis works with

11:03people telling people to do certain things. It's not that they don't care or they're under the

11:08control of the hypnotist. It's that they forget what's around them. Why? Because their mind is

11:14focused internally and on the dialogue with the hypnotist and is not paying attention to context.

11:20So it's a narrowing of context. But hypnosis for me has been very useful because A, it validated

11:25the relationship between vision and states of mind. It also checks off this box again,

11:29which is that to access neuroplasticity, what do you need? You need focus plus you need a state of

11:35deep relaxation. Usually first focus, then sleep or non-sleep deep rest. But Spiegel and his daddy

11:42figured out, because they're way smarter than I am, that you can get people into that perfect

11:48state of neuroplasticity by combining them both in real time through this atypical thing we call

11:53hypnosis. So I do a daily or maybe every other day hypnosis script that's about, it's self-directed

12:01hypnosis script of about five to 15 minutes. I'm usually trying to get myself to be less pissed

12:08off about something that I'm really pissed off about. Frankly, I imagine the stuff I'm really

12:13pissed off about in the screen on the left side. I think about all the things that make me feel

12:17good. And then I keep thinking about how angry I am. This is really how it goes. And then over time

12:21I've noticed, well, you're coupling that bodily state of calm to the anger thing. This is all

12:26very hard to do in talk therapy. No disrespect to talk therapy. There's a tremendous advantage

12:31to talk therapy that I myself have benefited from it. Although according to certain people

12:37in my life, not enough. But hypnosis works because it's capturing neuroplasticity processes.

12:44Thank you for that question.

12:49What are the most effective protocols for boosting the microbiome?

12:53Oh, well, here I'm very fortunate because my upstairs neighbor at Stanford is the great

12:59Justin Sonnenburg, and he and his wife, Erica, run this amazing lab defining all the principles

13:03of the gut microbiome, and they have a really cool idea.

13:06I don't know if he's serious about this, but I can't help but chuckle when I think that

13:12this might actually be true.

13:13We all know, this is definitely true,

13:15that we all carry around trillions of little microbacteria,

13:19not just in our gut that goes from one end of our throat to the other,

13:22any mucosal lining, eyes, genitalia, nose,

13:26we have microbiomes in our nose, et cetera.

13:29This is why we're heading into the winter months,

13:31being a nasal breather.

§02Transcript — part 2

13:33That sounds like crazy new-agey stuff, being a nasal breather.

13:36It was actually a book written by Paul Ehrlich and Sandra Kahn at Stanford

13:40with a foreword by Jared Diamond and Robert Sapolsky, the book Jaws.

13:44So these are some heavy hitters.

13:46And there's very good evidence that people who mouth breathe

13:48are making themselves more prone to illness.

13:52When nasal breathing, because of the microbiome,

13:54it's just a better filter for germs.

13:56So this winter, and always really,

13:58try and be a nasal breather all the time.

14:00One of the best ways to do that,

14:01if you're not into the mouth taping thing,

14:03which people do,

14:05is to try and do some of your exercise with just nasal breathing.

14:10It'll take a little while to get used to, but I'm not good at the nasal breathing thing because I'm always talking.

14:16The microbiome is all over us, and in us it's on our skin.

14:20We're actually exchanging it when we meet and we shake hands.

14:22Do you know what happens usually in the first 10, 15 seconds?

14:25Data from Noam Sobel's lab at the Weizmann has shown that we wipe our eyes.

14:29We wipe other people's molecules on us.

14:32We're really good at that.

14:33Just watch these interactions.

14:35Now everyone's going to be doing the germ-free handshake.

14:37They're going to be fist bumped.

14:38but there is this idea that maybe we are the house cats right maybe we're not just transporting all

14:46these microbiota because it's good for us what if we're just the vehicles and they're running the

14:51planet and they're like oh we're running out of some stuff like we should figure out somebody to

14:56take us to mars and then we'll take over mars i mean maybe it's all them and justin was the one

15:02that told me that i was like that's kind of eerie you think about it but there might be these other

15:06intelligences that are hijacking us. And that's kind of scary because we like to think that we're

15:12in charge and who knows. What's good for your microbiome or what's good for them, that is?

15:19Well, prebiotic fiber seems to be very important, but the studies of fiber, at least as it relates

15:26to the microbiome, are somewhat controversial. There was a study done on humans at Stanford by

15:31Chris Gardner and Justin Sonnenburg that show that people who eat one to four, you have to ramp up,

15:38servings of low-sugar fermented foods, this would be your kimchi, your natto, your sauerkrauts,

15:43your kefirs, your kombuchas, etc., per day develop a very robust microbiome.

15:51And fiber did not do that. In fact, fiber increased the so-called inflammatory,

15:56which is the markers for inflammation. But that doesn't mean that fiber is bad.

16:00Fiber actually is, getting enough fiber is correlated with a number of other things that are great,

16:05like reduced cardiovascular disease, for instance, cancers of the colon, for instance.

16:11So fiber and gut microbiota.

16:14Prebiotics, probiotics, probably only necessary if you have a dysbiosis,

16:18if you've been taking antibiotics or if for some reason you're depleted of the microbiome.

16:22One of the great ways to deplete your microbiome is to just eat highly processed foods,

16:26but hopefully most people aren't doing that.

16:29So prebiotic fiber and these low sugar fermented foods.

16:33And then someone always says beer, right?

16:35Someone always, yes, yes, beer will support your microbiome, but it might do other things too.

16:40So in general, low alcohol, low sugar fermented foods.

16:46Reduce the number of inflammatory markers.

16:48That's very, very clear from the Sonnenburg data.

16:51And then there are other ways, of course.

16:53The microbiome actually interacts with temperature.

16:55So the cold exposure thing is actually good for your microbiome.

16:58But, and I want to really emphasize this, if you hear about studies that such and such improves such and such, keep in mind that anything that improves your sleep, your microbiome, or your social interactions will improve basically everything else.

17:14And those are what we call modulating effects, not mediating effects.

17:19This is really important, and we teach first-year graduate students and medical students about this.

17:23like for instance if there were a fire alarm pulled right now god forbid it would modulate

17:27all of your attention but would you say that fire alarms mediate attention no it's not directly in

17:32the line of mechanism but it can adjust an existing mechanism so great sleep is great for everything

17:38but it doesn't control it directly and so things like getting great sleep keeping your microbiome

17:44healthy getting enough sunlight etc they provide a kind of buoyancy to all the organs and systems

17:49of your body, but they aren't necessarily the thing that cures ADHD. But of course, if you have

17:55ADHD or issues with focus, getting enough sleep will help. Is nutrition the way to cure your ADHD?

18:01No, but if you improve your gut microbiome, it's very likely that your neurotransmitter systems

18:06will improve. Limiting sugar will help, et cetera, et cetera. So there's reason to think that great

18:14sleep, solid nutrition, microbiome, social interactions, exercise, those are kind of the

18:20big five. There are others too, of course. With those, you set a good buoyancy to all the other

18:28systems. And then we get into the things of how to directly increase focus or modulate dopamine,

18:32and so on and so forth.

18:36Oh.

18:39Well, I realize some people are afraid of dogs.

18:43We actually have a dog stimulus in our fear lab.

18:45We get people that are terrified of dogs.

18:47We hired this dog trainer guy who has these pit bulls

18:50that will attack you while you're in VR.

18:52By the end, people are a little more comfortable with dogs in general.

18:58For you and me, if you're not afraid of dogs,

19:00that's not terribly terrifying.

19:03But if you are, even the thought of that can be pretty terrifying.

19:08A couple of things people have thought about.

19:10The eye contact thing.

19:12They make eye contact.

19:13We're big on eye contact.

19:14Humans too.

19:16Eye contact is meaningful in terms of oxytocin release.

19:20That's all real.

19:21Those data are more and more data that come out from better studies.

19:24Eye contact is a big deal.

19:25I think it's also that just the dogs are always game

19:28to show up exactly where you want to meet them,

19:31and they always show up in their most loving possible state for them.

19:35It's a pretty simple equation if you get it right.

19:38They need proper care.

19:41Costello was unique because the bulldog also,

19:44you don't want to get me going on dog breeds,

19:46but the bulldog also looks disappointed all the time.

19:50And then you do something it likes, and then it looks delighted,

19:53and pretty soon you're working for their approval.

19:56and we were like the odd couple, me and him.

19:59And I realized he's got me trained really, really well

20:01to do my best to please him and delight him,

20:05which delighted me.

20:06And there I was on the hook.

20:08So that's one reason.

20:09I think there's also another reason,

20:11which is super nerdy,

20:12which is this C-tactile fiber thing,

20:14which is you have these little nerve endings in your skin.

20:17And we know, of course,

20:19that oxytocin is released from parent and child.

20:22We know this from neuroimaging, et cetera.

20:24We know oxytocin is released from romantic interact, non-sexual romantic touch.

20:28One of the things that is very powerful for the release of oxytocin, very powerful,

20:33is non-sexual grooming touch among members of a species or even across species.

20:40Those pictures of monkeys, you know, picking around in each other

20:44or people who insist on popping things on one another

20:47or people who go to the hairdresser or the barber and they like, you know, touch.

20:51It doesn't even have to be massage.

20:52massive oxytocin release. Those data don't get as much play as all the data on oxytocin and love.

21:00It's called the love hormone, but it's basically a neurochemical signaling system for this

21:06interaction feels good and is very much of the present. And I think that's an important distinction

21:11to make more broadly is that dopamine is really about the pursuit of all things beyond the

21:18confines of our skin. I'm going to get that thing. I want that because it's all about anticipation.

21:24And when you have some distance between yourself and the thing that you think will deliver

21:27whatever it is you want, usually pleasure in some form or another or excitement, whatever your

21:32pleasure is or combined, then you actually have to mobilize. And dopamine is the precursor to

21:37adrenaline. A lot of people don't know that adrenaline is made from dopamine. It gets you

21:41into motion. Then you have the reward systems that are more about what you have from your skin

21:45surface inward. So this is gentle touch, holding hands, and indeed stroking your dog. Probably does

21:54that for you. It activates these C fibers, as they're called, in your skin, which feed right

21:58into these serotonin and oxytocin systems of the brain. Sounds a little pop psychology-ish, but it's

22:04a real thing, and it exists in essentially all mammalian species. So I think a lot of us just

22:08like dogs because they'll let us just pet them all day. You know, some people like to be touched

22:13a little bit more or less, even when they trust

22:15it's all consensual,

22:18age-appropriate, context-appropriate,

22:20in this case, species-appropriate.

22:22Those are the conditions. Very important.

22:24When I was a kid,

22:25I had to, you know,

22:27I don't know why, my sister's in the audience, I don't know why

22:29she decided to do this in the first place, but I loved

22:31having my face kind of like

22:33pet like that. I still like it,

22:35but don't try it, because she's the only one,

22:37she can't do it anymore even.

22:39So, we all have these things that feel good,

22:41and I think it feels good because it releases

22:43these chemicals. And these are ancient systems, ancient, ancient systems that we all have. And I

22:50think dogs let us do that. And cats toy with us with this one, because there are those cats that

22:55let you pet them. But most of the time, they're doing it to you, and then they withdraw. And I

23:00don't know many dogs that do that. So I think people, I'm going to answer the question finally,

23:04I think dogs, we love them so much, because they let us pet them as much as we want.

23:08and cats play this very diabolical game

23:11that's a lot more like human relationships.

23:17How can night owls best function in a society

23:20made for morning birds?

23:22Can you change your chronotype

23:24or do us night owls just have to suffer?

23:26Okay, well, as a former night owl,

23:29I used to work long hours in the lab.

23:32I still work long hours, but less in the lab.

23:35Just so happens that's the way the career goes.

23:37I'd put tinfoil on the windows.

23:39I would lock the doors.

23:41I'd blast the music.

23:41And I would stay there over the holidays until I had to go home just for the holiday events.

23:47And my clock would drift.

23:48So I became a night owl.

23:49And then my clock would flip and everyone was gone.

23:52Your mind gets really tweaked when you're not interacting with anybody.

23:55By the way, seeing faces in the morning and seeing faces at some point during the day,

24:00once you're ready to face the day, very important for mental health.

24:04This is something I wish more people knew about.

24:06It also, and here I'm not trying to evoke any kind of sentimentality, but when you think about people who just are clearly not doing well, whether or not they have shelter or not, how often do we actually make direct eye contact nowadays?

24:21It's not very often.

24:23So eye contact is important, but I've also shifted to being a morning person.

24:28So here's the thing. If you are a true night owl, that means that your circadian clock, meaning the genes that control the area of your brain and your hypothalamus that controls wake sleep cycles, is fundamentally different.

24:42Very unlikely you'll become a morning person without being a kind of angry morning person.

24:49So you can use that argument and you can cite me.

24:52However, as we get older, it is true that the amount of slow-wave sleep to REM sleep tends to change,

25:00and we can do better on shorter bouts of sleep, mostly because we're getting less rapid eye movement sleep.

25:07And even if we try, we can't.

25:09Those people would probably be better off sticking to a limited amount of sleep at night and then getting a short nap.

25:15The rule with naps is nap if you want to, don't if you don't want, but not if it interferes with your nighttime sleep.

25:21and if you can't nap, do some sort of non-sleep deep rest or NSDR.

25:24As I refer to it, non-sleep deep rest.

25:26So you can probably shift your clock by anywhere from two to eight hours,

25:31and that's true for jet lag as well.

25:34Light is going to be the best way, but if you really want to shift,

25:37you're going to have to stack the big three or four.

25:40Light, so get light when you want to be awake.

25:42Temperature, you have to increase your body temperature to wake up.

25:44You have to decrease body temperature to go to sleep.

25:47Keep in mind, if you get into an ice bath or cold shower, you get very, very cold,

25:50but then what happens it's like putting an ice pack on the thermostat your body temperature goes

25:55up remember thermogenesis that's the warming of the body in response to cold of course if you stay

26:00in a long time you'll you'll get crispy cold you turn to a popsicle but the idea is that if you

26:05take a cold shower and you get some bright light and you get some exercise and you drink some

§03Transcript — part 3

26:08caffeine you can train your system to expect that at a certain time of day and you'll want to go to

26:13sleep a little bit earlier or much earlier and you'll want to wake up when you stack those things

26:18But that also means not taking caffeine and cold showers and doing exercise late at night.

26:23So it's going to take some work.

26:24But those are the big four.

26:26It's going to be light is the most powerful way to shift.

26:29More light, awake.

26:30Less light, asleep.

26:32Temperature, increase, awake.

26:33Temperature, decrease, asleep.

26:36Food is the other one.

26:37Eating, you can force yourself to eat breakfast even if you're not a breakfast eater.

26:41This works when you travel too.

26:43Just get onto the local meal schedule because you have a clock system in your gut, believe it or not.

26:47you want to synchronize that with your brain and then activity getting some sort of exercise but

26:52it takes a little bit of work but you can do it you can definitely do it if you're nocturnal that's

26:57weird unless it's because of your work in which case there are tools for shift work that we've

27:02put out there on on the podcast your podcast has been wild success how do you see it growing over

27:06the next few years i honestly i try and live in the tunnel of lack of understanding and awareness

27:12about what's happening with all this.

27:14I really do.

27:16Lex suggested we do the podcast.

27:18That's a true story of doing it.

27:20I still really do feel very much like I did

27:23when I was a little kid.

27:24I'm just going to keep trying to learn and share.

27:26I'd love for people to share the tools.

27:28I don't want credit for them.

27:30If people credit us, great.

27:31But if you think about it,

27:32most of what we talk about are not things that you buy.

27:36These are tools that, again, work the first time every time.

27:38I always say behavioral tools first,

27:40then nutrition, supplementation. And then for some people, prescription drugs or some of these more

27:47experimental drugs make sense. For some people, it doesn't. For instance, I don't think kids should

27:51be doing psychedelics. I mean, childhood is enough of a psychedelic experience in and of itself.

27:56But I had an amazing clinician. He's actually a triple board certified psychiatrist, neurologist

28:02at Stanford, Nolan Williams on the podcast. And he talked about even the use of Ibogaine and MDMA,

28:08even in some younger populations, but again with therapeutic oversight.

28:12It blew my mind.

28:14I also didn't know this, that MDMA I thought was toxic.

28:17Please don't just take it off the street,

28:18but if you're interested in clinical trials,

28:20there are great clinical trials happening through MAPS,

28:22and you can look at Nolan's website as well.

28:25Most of the knowledge about the effects of MDMA is from the LDS community

28:30because they volunteered for these studies

28:34because it's not on the banned substance list.

28:38And so there's a lot of knowledge and they don't tend to, or they don't use other substances

28:43like alcohol and marijuana and cocaine.

28:47So much of what we know about the effects of MDMA on the body and brain is from that

28:51community, other communities too as well.

28:54So what are we going to do with the podcast?

28:56Well, every Monday I'm going to keep putting out episodes until they put me in that grave

29:02with a thing.

29:03Thank you.

29:05It is a labor of love and it's a lot of fun.

29:08and we're just always trying to make them better, clearer.

29:11Somehow they're not getting shorter.

29:13I always tell Rob, this one's going to be 90 minutes.

29:15And he's like, yeah, I'll believe it when I see it.

29:18I think for me, one thing that it has brought that's really wonderful

29:22is the opportunity to learn from people in other domains

29:26that are far better at putting information and things into the world.

29:30So I've been, I hope he doesn't mind me saying this.

29:33I've been very blessed.

29:35I've become really good friends with Rick Rubin,

29:37who's been really helpful to me.

29:39He has an amazing book on creativity coming out.

29:41That's not a plug for the book,

29:42although I guess I just kind of accidentally did it.

29:44But Rick, of course, has produced and created

29:48all this amazing music,

29:50everything from Run DMC, Beastie Boys, Slayer, Johnny Cash,

29:54everything's just amazing.

29:55And one of the things that he's been impressing on me

29:58is that it's very important to stay focused

30:02on the process of what you're doing

30:04and to really not get into too much of how that's landing.

30:10So I do like to hear when things are not clear.

30:12That's really helpful to me.

30:14I do like to hear suggestions about great people to bring on the podcast.

30:17I love criticism most of the time.

30:22I try my best.

30:24It's hard sometimes, but I really try and just absorb it for what it is.

30:28But I love that aspect of interacting in this,

30:31even though this is fairly unidirectional.

30:34hopefully there'll be more opportunities for kind of dialoguing and learning what's out there my real

30:40hope is that practitioners will start to incorporate things and again it's not about me i'm gleaning

30:45from fields and the work and discoveries of other people and trying to thread across fields so that's

30:50where i see the podcast going just more of the same more the same more of the same but a lot more and

30:56more topics as best we can lots of guests and we actually have an episode with rick coming out at

31:01some point about creativity, which I think is one of the more interesting aspects of our being.

31:07So you watch for that. What is a stress inoculation protocol for the workplace anxiety?

31:14Speaking, does the principle of staying calm under high adrenaline? Yeah, definitely. I think if you

31:19were to pick some sort of practice that you could do privately and safely, again, how cold should

31:25you make the water? Cold enough that it's really uncomfortable and you really, really want to get

31:28out, but you can safely stay in. And that's why we never say 40 degrees because for, you know,

31:33you can kill yourself with cold water. It's just hard to do. Um, you have to get really,

31:38really cold before you kill yourself. Um, and open bodies of water aren't good. Actually,

31:43I told my friend Samer Hattar, he's the director of chronobiology unit at the National Institutes

31:47of Mental Health. He came on the podcast, got him really excited. He's great about all the stuff on

31:51light and sleep. Taught me a lot of that over the years. We're good friends. I told him about the

31:55cold water thing and he got into some river in Bethesda and almost drowned. I was like,

32:00Samer, now he has this story about how he almost drowned and what he was, and he thought

32:03about a paper he wanted to write while he was almost drowning. So just be careful, open bodies

32:10of water, that kind of thing. But I, I think you can quickly see within about a week or so of doing

32:16some sort of deliberate adrenaline release. It could be cyclic hyperventilation, 25 hyperventilated

32:22breaths with a short breath hold repeat done two or three times we have good data to support that

32:27in the lab you see massive shifts in people's baseline level you become a little bit more like

32:31Costello you really do and the way to think about is if you are more on a seesaw than on the

32:38continuum you get better at loosening that hinge and controlling that hinge or you can imagine

32:44you know kind of moving up and down that seesaw a little bit more easily and then of course you

32:49have to place yourself into the environment. You have to test yourself in that environment. And some

32:54people will do Toastmasters and things like that, and it can work. My way, I don't know if it works

32:59for everybody, but my way is just start talking, don't stop. I can't feel the stress.

33:06What do you think will be the next hot topic, new trend in the field of neuroscience,

33:09behavioral therapeutics? Ooh, I like that, because I have a lot of opinions about that.

33:14First of all, I do not think it's going to be brain-machine interface.

33:19My good friend Eddie Chang, who I've known since we were nine,

33:21he came on the podcast, he works on epilepsy, he's a chair of neurosurgery.

33:25We had a bird club when we were kids.

33:27Had two members.

33:30You had to know the names of all the talking birds,

33:34and then you had to know which one was the best talker, and it's the mynah bird.

33:38And, of course, no one wanted to join, no one even took the test,

33:41But he became a neurosurgeon and does brain-machine interface.

33:45He's doing truly incredible work getting people with locked-in syndrome

33:48to speak through a device implanted under the skull.

33:52They just think what they want to say.

33:54These are people who haven't moved or shared a word with anybody,

33:57and they're now communicating.

33:59But here's what's really cool.

34:00He has also realized that facial expression is a lot.

34:04It's one thing to see on a screen what somebody in a chair

34:07or a hospital bed is thinking.

34:09That's wonderful.

34:10but facial expression is such a rich part of this.

34:13So this is a really good use of AI.

34:15He has now created very realistic iPad images

34:19of that person's face

34:20and so they're actually speaking the words

34:21and people form a deep relationship

34:23to the person who's right next to their avatar.

34:27So that's a positive use, I think, of avatars

34:30and Eddie's doing amazing work.

34:32That kind of work of brain-machine interface,

34:35Neuralink, et cetera,

34:36I think is going to be very useful and popular

34:39in the realm of therapeutics for Parkinson's,

34:42movement disorders, epilepsy, locked-in syndrome, etc.

34:46I think we are many, many, many decades

34:48from chip implantation into the brain

34:51for things like enhancing memory.

34:53And frankly, I wouldn't want it.

34:56Not because I wouldn't want to enhance my memory,

34:58but because of what I said earlier,

34:59is that the nervous system has a certain amount of real estate,

35:02and you don't want to make that real estate very lopsided.

35:06And so I think we're going to see something very different

35:08in the next 10, 20 years, and I hope, hope, hope this carries over to younger populations.

35:16I think we're going to hopefully start learning about our nervous system and what it can do,

35:20and the fact that we have these preexisting circuits in us that we can learn to leverage

35:25that work first time every time.

35:27So I'm strongly biased in my answer, but I think that it still remains an open question,

35:33for instance, whether or not people could require less, perhaps, or no medication for

35:38certain things. And I say certain things because for conditions like schizophrenia, bipolar

35:43in particular, medication, OCD has proved very effective. But then there are a whole

35:47other set of conditions like depression and anxiety for which behavioral tools really

35:52work, but most people just don't even know they exist. So that's my hope. And again,

35:58I love the therapeutic community could try and expand their toolkit. I also think we're starting

36:03to see a blurring of the lines between different fields of psychology. So it's no longer psychoanalytic

36:08versus cognitive behavioral versus dialectic versus EMDR versus hypnosis, that it's all going

36:13to be governed by some central principles. All those camps, it's just, it's just silly, frankly,

36:18to me. It makes sense academically why those came to be. But in neuroscience, we had the same thing.

36:23You used to have to pick, it was like a John Hughes film from the eighties. Are you going to be a

36:27jock or a punker or a popular kid. Now it's not like that. And half this audience is looking at

36:32me like, what are you talking about? And that's exactly the point, which is I'll never forget.

36:36I grew up in the skateboard thing. The first time I saw someone wearing skateboarding shoes,

36:39I was like, damn, they skateboard. And they're like, no, they just, people are just wearing

36:42this stuff. Right. So what you started to realize is it all blended together, which is great.

36:48And in the field of neuroscience, you used to have to pick, are you an anatomist or a physiologist?

36:52Are you into neural computation?

36:55Now your lab has to do it all, or you collaborate with people.

36:57Those divisions have really melted because people are interested in questions, and they're interested in answers.

37:03And don't get me started, but the careerism of the requirement for everyone to have their own independent laboratory and say, this is my mission, that is one of the worst things about science.

37:14Because everything we know says that collaboration, collaboration, collaboration leads to faster progress.

37:21and you know I'm not going to take on the whole academic system it's been very good to me

37:25but I'd like to see a blurring of the boundaries it used to be that labs weren't here I'm really

37:31guilty Huberman lab but it used to be that labs were named after the problem they worked on

37:36vision lab stress lab happiness lab I like that quite a bit more but I screwed up and

37:42called this whole thing the Huberman lab you had a number you have had a number of performance

37:49nutrition fitness experts on the show what changes have you made your fitness protocol include

37:52nutrition oh um yeah well i'm an omnivore so i like those things they call carbohydrates they um

38:02and i eat them in moderation and so i've never really been too extreme about any of this

38:08or the fasting thing although i do kind of just i'm not very hungry in the morning that's also

38:12because i like to eat a lot at night um i wake up not that hungry um so what have i changed well

38:19terms of the fitness stuff I've definitely started to incorporate more nasal breathing when I do

38:24cardiovascular work because it has eliminated any sleep apnea I had and sleep apnea is very very bad

38:32very very bad you know I wish I could say snoring was no big deal but we know based on work at the

§04Transcript — part 4

38:39Stanford sleep lab Penn sleep lab other sleep labs that people who have sleep apnea are really

38:44in for trouble for a number of reasons. So you want to learn to be a nasal breather. And if you're,

38:49some people will tape their mouth shut with medical tape when they go to sleep. Other people

38:53will just start doing cardiovascular work, keeping their mouth closed. And that requires that you not

38:58go too intensely, but it does create a dilation of the, of the nasal passages. Those sinuses can

39:04dilate. So I've definitely done that. And at the end of training, I try and do a one minute or three

39:09minute decompress, not immediately look at my phone to kind of learn to shift from high intensity

39:14kind of thinking and to lower intensity thinking and shift throughout the day. Task switching,

39:19I think, is going to be a big area of science and neuroscience in general. We still don't know how

39:26to task switch well, how to shift the mind from focus to defocus and back again. That's something

39:31that there's, by the way, this is, I think, a rich opportunity for people to develop tools.

39:37We don't know a lot about that. We got too caught up on consciousness flow and free will.

39:40and that stuff is great but I like as you can tell I like tools I like physiology I like the

39:46things that work in my lifetime and that we can figure out and agree upon in my lifetime

39:50let's see got it and I'm told that this final question I when they put the clock up here

39:59earlier too they said that we're going to run it for 60 minutes my first question was where's the

40:03snooze button so you're going to keep going but I think they're going to hold me to it I know people

40:07This is New York after all.

40:09There are other fun things to do.

40:10For things that take a long time, career pursuing a degree,

40:14is there a right way to know that we're on the right path?

40:17Is there a way to know we're on the right path?

40:20Thank you for that question.

40:21I get asked this a lot.

40:24And gosh, there's so much information out there.

40:30So much information about this.

40:32We don't yet have a gauge of whether or not we're in too much stress or not.

40:39But there is one tool that's used in the freediving community and in other communities that you can use as a kind of thermometer of how well you're functioning.

40:49And some of you may know it already, and if you do, forgive me.

40:51It's this carbon dioxide tolerance test.

40:54So why am I answering this question this way?

40:56Well, I like to start with actionable tools.

40:58if for instance you were to just take three or four breaths and then take a big deep breath

41:04and then do a very slow controlled exhale could be through your nose or through your mouth ideally

41:09through your nose and you're trying to make that exhale as long as possible until your lungs are

41:13empty and you time that that's the called the carbon dioxide discard rate or discard rate or

41:18the exhale discard rate and it tells you how well you're controlling your diaphragm using something

41:24called the phrenic nerve. It also tells you how well you're managing carbon dioxide and how well

41:31you're managing stress. And if you're very stressed, that number will be very, very short.

41:35And I'm not talking about how long you can sit with lungs empty. I'm talking about an honest

41:38appraisal of how long you can control that exhale for. And if it's anywhere from zero to 20 seconds,

41:46your stress level is high. And if it's from 20 to 40 seconds, it's moderate. And longer than 40

41:53seconds means you have good control over your carbon dioxide system more or less. Now these

42:00are averages and guess what? It has nothing to do with fitness and also it has nothing to do with

42:06you per se because if you do this when you first wake up after a good night's sleep you'll have a

42:10long discard rate. If you do this after running you'll have a short discard rate. You're not out

42:16of breath you're just not managing the system very well. So you can touch into this every once in a

42:20while as sort of a blood pressure reading type thing. This is very back of the envelope. It's

42:24not perfect, but it works well enough that alongside things like resting heart rate,

42:30heart rate variability, et cetera, you can get a window into how well you're managing stress.

42:36Why am I answering this question this way? Well, this is something I recommend doing every once

42:41in a while, especially if you are in a period of a career or any kind of pursuit where you are

42:47feeling like you're grinding. I think once your carbon dioxide discard rate starts to really get

42:54shorter and shorter, you're having trouble sleeping, I think it's time to focus on

42:59reestablishing that buoyancy to your nervous system. Because then and only then can you make

43:04good judgments about whether or not you're in the right trajectory for you. Now in terms of the

43:09larger psychological themes, are you doing something that brings you meaning or not? That

43:12gets into some complicated territory. We're very good at assigning meaning retrospectively.

43:17and saying, well, that was a good experience because we had it and we learned from it, etc.

43:21But I think most people like to avoid things that they can only look back on

43:25and say it was useful because I learned something from it.

43:28And for that, I'll just give the default, but I think, at least to me, accurate answer,

43:34which is the more often that you can tap into that feeling of excitement and delight in your work,

43:42even if from small things or from surprising things or from the social interactions that

43:47you're able to glean from that work the longer and better you're going to be able to pursue that line

43:54of work for me is in graduate school I was very isolated I worked alone in the lab maybe it was

43:59because of the tinfoil I put on the walls or the windows I don't know in fact my graduate advisors

44:04one complaint was that I seemed unfriendly I wasn't unfriendly I was just busy but I got to

44:09be very good friends with the janitorial staff because they were the only one around at the

44:13time I was working or a few other people. And those small interactions actually became very

44:17significant to me and became sources of brief, but to me at least at the time, meaningful social

44:24exchange. And of course, eventually I made friends and had relationships of other kinds and things

44:29that were healthy as well. But I think learning to tap into this love of what you're doing is

44:36sometimes hard, but you have to look for it. It's an active process. And I'll default to the work

44:42and the podcast that's coming with Rick Rubin. And a lot of what he talks about in terms of

44:47creativity is about accessing what he and others have talked about as the source. If that is an

44:52abstract, I don't know what is. But the source is this ability to see yourself as more of a

44:58portal for getting certain things done in the world than being so careerist and focused on

45:05whether or not outcomes are really matching what you need. It involves some mental flexibility and

45:10is of course okay to pivot back and forth. But we can only access this feeling of delight and joy

45:17and this feeling that we're somehow connected to some larger theme, aka meaning, I think when we

45:22are able to be calm enough and not so focused. But in order to get anything done, we have to be

45:26hyper-focused. And that brings me back to the basic principle of today's whole discussion,

45:30which is that it's not about landing yourself in a state of focus, motivation, and drive

45:35or in a state of deep sleep, certainly not in a coma.

45:38It's about being able to move up and down the various continuums

45:42that allow you to access focus and real gas pedal down to the floor kind of thinking and action

45:50but then also deliberately back off, transition to periods of rest.

45:55And the real key is for you to feel like you're in the driver's seat.

45:58If we know anything from the last hundred plus years of psychology and neuroscience literature,

46:04it's that if an animal or a person feels that they are in control of the physiological process within them

46:11and they know they can get themselves out some way, somehow, at some point

46:15and back into a state that they want somehow, some way, at some point,

46:19well then all the language around meaning and happiness and delight starts to emerge.

46:25so learn to move along those continuums

46:29learn to do it deliberately

46:30and I wish you the very best of luck in it

46:33I know it works

46:34thank you

46:36thanks so much

46:38thank you

46:39thank you

46:42thanks so much for coming out

46:44I really appreciate it

46:47and

46:47grateful to our sponsors

46:51of course thank you and to all of you

46:53for your time

46:54I know there's a lot to do in the city, and I hope everyone enjoys it.

46:58And of course, I'd be remiss if I didn't say thank you for your interest in science.
