  1. Well, I want to say several things. First of all, thank you for having me on again. It's an honor and a pleasure. And I don't say that formally. I really, truly mean it. The Humberman Lab podcast, as I always say, only exists because you gave me the suggestion. And I'm so grateful that you did. So, thank you. And for doing what you do, you are brave and you first first first first first in. Just keep going. And then, in terms of our friendship, I mean, I think you know, and if you don't, I'm going to just keep telling you anyway by texting in person. You're an amazing friend. There's deep trust. There's immense respect. And I love you, brother.

  2. I look forward to the day that our kids are Roland Jiu Jitsu and my kids are hanging out with your kids. And if that notion sounds even remotely interesting, then fun, then it's sort of like you kind of backpedal from that and you go, what has to happen? How do you get it?

  3. Because ultimately a relationship, however one structures it is going to be part of your daily routine. So at the point where you're like, you know, I'd really love to wake up next to somebody and do blank and blank together. And then I'd love to work and then we meet for dinner and then we, you know, take the dog for a walk or take kids out or whatever it happens to be, take a trip and do it. You have to be one has to be in the mindset of wanting to do couple like things. People and a lot of people don't think about it that way. They either fall into something or they They don't see the benefits of coupling up. I think that the pandemic tuned people's awareness to the fact that some things are indeed easier on your own. Depends on finances, et cetera, et cetera. Lot of things are made better done with other people.

  4. I'm going to make this happen one way or another. And you don't force the discovery of that person. But I mean, I've occasionally said, hey, I think you should meet this person or that person. And, well, it wasn't maybe my judgment might have been off, but the timing wasn't right or something. But I think that, yeah, it's a decision. And it also has to do with life structure. I mean, there were years, so when I was in graduate school, I didn't want a girlfriend. I just wanted to be in lab. And sure, I had romantic dating interests, but I wasn't going to meet them through a committed, you know, live together situation. Wasn't where I was at. As a postdoc, things are a little different, et cetera, et cetera. But at some point, it's sort of like, what do I want my daily routine to look like?

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  5. Yeah, actually, this comes from a friend of mine who is in a really excellent marriage with great kids and family and high demand life. It's a decision. Like at some point, you just prioritize it as, okay.

  6. Normally, it's interesting. Normally, sociopaths don't team up because they manipulate each other. Sociopaths sadly are usually only interested in manipulating the highly pliable or unsuspecting. But when romantic attraction is woven in, then it gets really diabolical.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  7. Yeah, and they'll say we got lucky, or it was been hard, or this and that. I think external conditions being a little tougher is helpful for a couple.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  8. I agree, but at some point, like if you've done it enough times, you know, life is finite. It is beautiful to see these couples that seem very much in love. Despite many years, despite having been together many years.

  9. Takes us back to that primitive circuitry that is as primitive and basic as hunger, thirst, the desire for heat when we're cold, the desire for cold when we're overly warm. It's dinorphin. I mean, when somebody leaves, like when somebody you are attached to leaves by death or by decision or you're forced apart, the dinorphin release is massive. It is true discomfort. People feel anxiety and discomfort. And moving through that is the hell of a process. I mean, if I knew how to best break up at a neurological level, or if you could just plug yourself into a wall and reset, I mean, I do that episode tomorrow, but we don't have that knowledge.

  10. You can't go in there fully protected. And yet you also can't go in there with no boundaries because you'll end up beat up. What's that quote if you want to be a warrior prepare to get hurt, if you want to be an explorer prepared to get lost, and if you want to be both, and if you become a lover, prepare to beat both or something, something like that. I forget. This is one of these Instagram type things that you see passing by and you go, oh, it's pretty true. Love's scary because

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  11. But you also have to be careful. I get a lot of questions from God. You have to be careful of the questions you ask in a relationship, too. You have to make sure you really want that information. And it's not just about people's past, right? If you ask somebody how they really feel about something about you and they tell you, that may be soothing, it may be intensely stressful. You have to be, here's one thing I know for sure for a relationship to work, you have to be brave.

  12. The psychological sense, not in the way they're typically thrown around nowadays. So the idea, you know, in some cultures, men and women will only touch for two weeks out of the month. And then for the other two weeks, The excitement and the sensuality, and the sexuality is very heightened. And then they go back to this kind of distancing. Now, I don't think that's feasible for most people, but if you look statistically, those relationships tend to last a very long time with at least reported mutual feelings of intense attraction for many, many, many decades. So human beings need to learn how to at least understand and control these dynamics. And there's a lot of divorce, there's a lot of cheating, there's a lot of stuff out there. It'd be great if people could resolve some of this stuff inside of the relationship, in my opinion.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  13. Ultimately, I mean, right, there's the dopamine phase of a relationship, and then there's the serotonin phase, the kind of more mutuality, coziness, and sweetness. There's a great book about how to make sure that the dopamine component and the serotonin component, so to speak, go on forever. And it has to do with, you know, when you first meet someone or you're attracted to them, you're essentially objectifying them, meaning not in the way people might think, you are not dependent on them for emotional stability or survival. As you get close to somebody, you really come to depend on them and then you tend to objectify them less. And so this book, the book, the name is kind of corny, but it's written by an analyst again. It's called Can Love Last. And it's a book about how really good, strong relationships are the consequence of people constantly moving through this dependency objectification dynamic. And I use those words in the true.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  14. There is a power dynamic in relationships, sometimes, not all, but in some relationships, it works much better if one person leads and the other person follows. In other relationships, it's more mutuality works best. People need to know what they need. And so knowing what you need and what you crave is really important. And then once you do that, you can create the relationship you want. I've seen that over and over again. And people are different. But I think that

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  15. If your main focus is on you want to have good boundaries, et cetera, but on tending to the relationship, doing a little bit more than you think you ought to do. If everyone does that, it goes great. I mean, I'm sometimes so positively struck by how supported I feel because for many years I was just kind of doing everything on my own. So any little thing, I'm like, oh my goodness, this feels huge. And also I think the dynamics have to be right. Let's be really honest. This is a little bit of a tricky topic.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  16. Isn't just one, but at least in the top five is Master or at least be good at Autonomic self regulation. Know how to calm yourself down. Don't expect the, like looking to anything external to soothe yourself is it puts you in a terrible position to be a caretaker of yourself and other people, right? So learn how to self-soothe, right? Learn how to calm your mind, steady your actions, steady your voice. There are tools to do that. We talk about in the podcast, but elsewhere, have that in place. I also think that if

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  17. No, it wasn't always obvious to me. I've really enjoyed wonderful relationships. And some have been hard, and there's been certainly been a lot of growth. I'm on good terms with almost all my former girlfriends and close with some enough that I know their spouses and I'm close with their families. But no, it wasn't. And I think that when people say relationship is hard, the only really hard part about a good relationship is just dealing with oneself and making sure that you're staying in that. Mode of caretaking because I do believe that if one is mainly focused on taking good care of the other person provided they're also focused on taking good care of you, to some extent and we're good at taking care of ourselves, everybody flourishes. Everything gets better. But no, I don't think I experienced that until fairly recently.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  18. Reacting, it's not just a two arrow system, it's at least this four arrow thing. But there's also the element of nurturing, right? I mean, I think that going through life with somebody is so much better than going through it alone. And I'd never thought I'd make that statement.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  19. Which is how you feel about how they feel. And then they have an era of how they feel about how you feel, right? This is why if someone else is moody or somebody else is upset, there's one version of ourselves where we respond to that or they respond to us. But there's another version where we respond to that, but it's also a processing of what it means for us that they're behaving that way or feeling that way. And this, again, leads us back to that early attachment circuitry because of a parent was stressed the child's role is not to soothe the parent. In fact, healthy models of parenting say that children shouldn't actually know how their parents feel for like the first eight years of their life. They're not supposed to be in that mindset of empathizing for the parent. This is often not the case. But maybe the cutoff isn't exactly eight, but you get the idea. So the dynamics of a relationship are where the learning is because we learn how we react to other people.

  20. Some iterative. You know, the dynamics, right? I mean, you're merging two nervous systems. This was once described to me very well by an ex-girlfriend who's truly brilliant. She's really brilliant. She said, you know, there's four arrows. This is maybe to an engineer or like a, so it makes sense. There's how you feel towards the other person. How they feel towards you. But then there's an arrow that comes back to you.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  21. But I can answer it in part, right? Because partially because you're very busy, partially because you've decided that until it's time, you're going to wait until it's time it's time, right? I mean, until it's time you're waiting. And then, I mean, you're not saving yourself from marriage, I don't think. But in some sense, yeah, your wife, your future wife is out there.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  22. And no one knows what other people are doing or what's normal. We kind of know deviancy, we know perversion, we know the extremes. We know the rules. Hopefully, people know the rules. But let's just be, there are a lot of people in the academic community, in particular at certain East Coast schools not to be named that are in open relationships. This is more common now. It's not very common, but it's more common. And, you know, obviously that's a way of bypassing some of these more primitive emotions about jealousy, et cetera, and leveraging them towards maybe even ongoing relationships. I'm not passing judgment one way or the other. I always say four conditions have to be met for any discussion about sex and sexuality or sexual health. Age appropriate, context appropriate, consensual, and species appropriate.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  23. And the dynamic is exactly the same as the dynamic she had with her mother. That's actually a common occurrence, even though in this context she's heterosexual. She's romantically attracted to men. What is seen over and over again is that the dynamic with one parent can be transferred onto a romantic dynamic, but it doesn't have to be that if it was with the mother, then it only has to do with relationships to women. So gender is interchangeable because these circuitries are presexual. They're laid down in our brain before the brain has any concept of sexual interactions. It's pre-pubertal, excuse me. And so there are a lot of interesting examples in data to support this. The book attached is a pretty interesting book by two psychologists. One, I think is at Columbia University that talks about how childhood dynamics carry over to adult romantic attachment. So as you can tell, I get pretty...

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  24. Without question. And of course, early experiences too, and traumatic or positive or neutral. The thing that's really important to remember, though, in this transfer of circuitry from one role to another is that And it certainly consistent with psychoanalysis that gender is interchangeable, sex is interchangeable. So, for instance, let's say you had a wonderful relationship, let's say this, let's take a hypothetical person. I'm truly not referring to myself. Let's take a young woman who has a wonderful relationship to her father and a just absolutely terrible abusive relationship to her mother just for sake of example. She then goes into adulthood and she is drawn to very abusive men, not always, but let's just use in this example.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  25. There's a book called The Erotic Imagination. It's a very psychoanalytic book written by a psychoanalyst that talks about how, well, here's the uncomfortable reality. Freud was at least right about one thing, which is that the brain circuitry that you used to develop attachments to your caregivers, mother and father or other caregivers. Do not disappear when you hit puberty. They are repurposed for romantic and sexual relations. And so this is why the whole notion of anxious attached and secure attached stems from childhood attachment patterns, but it carries over to romantic relationships.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  26. Well, maybe nothing, you know, what are you specifically concerned about? And then over time, if you pull on those threads a little bit, you know, you get your answer. Sometimes I'll just get a direct question. But I think that the psychology of all this and in terms of jealousy and the terms of notions of roles and relationships is very dynamic right now. And I'm fascinated by this. So we're going to do a four-episode series.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  27. Whether or not people have kids or not, and what impacts that. But we're going to do an episode on menopause andropause. What's very surprising is I get a lot of questions about sexual health from the young male audience. Which tells me that, well, here's what I think it reflects. I think that women because of their menstrual cycles early on start to talk to one another about changes in physiology and psychology as a function of this 28-day cycle that they all experience sooner or later. Males, there's less of a conversation and it usually arrives in code. People will say, hey, what should I take to increase my testosterone? And I'll say,

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  28. Counterintuitive and it kind of works like a seesaw. I mean, there's arousal, then there's relaxation, then there's arousal. But then immediately after orgasm and in males ejaculation, what ends up happening is there's a rebounding of the parasympathetic nervous system, which it leads to oftentimes people feeling very relaxed or falling asleep. So I'm going to do a short series on sexual health that will be that will include stuff about sexual performance, but also I'm working on getting an expert guest who can talk about some of the neurologic changes that happen as a consequence of sexual activity. And we did an episode with a guy from UT Austin here, David Buss, who's an evolutionary psychologist, talking about went pretty deep into some of the typical and unusual dynamics of mating relation

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  29. Early development mainly, and the effects of hormones later on that template. We will be doing a, I'm actually putting together a series on sexual health, everything from The menstrual cycle, which both men and women should understand, of course, understanding arousal, understanding, for instance, a lot of people don't realize this, but that orgasm is actually the consequence of activity in the sympathetic, meaning the stress arm of the autonomic nervous system. Whereas arousal is the consequence of the activity of the parasympathetic, the calming aspect of...

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  30. We've done the Monoptimizing Testosterone and estrogen, and we touched a little bit on libido. And somewhat on sex performance, but not much. We did an episode on relationships, love, and desire, where we touched on libido specifically. So just as a quick mention of something, a lot of people take SSRIs or antidepressants that can disrupt sexual function. There are a few compounds like Maka root and tonga ali and things like that that at least in a few studies in humans have been shown to offset some of the sexual side effects. Now in terms of sexual and then sorry the episode on sexual development was about how the brain and body become organized in certain ways, how the brain becomes organized if you have X chromosomes or Y chromosomes or etc

  31. So, the folks from the plunge, maybe could bring Lexa a plunge. He certainly deserves one. And we can go side-by-side coffin style, or we can face one another and we can do that.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  32. I mean, if you ever waded into a cold ocean, everybody's kind of like holding themselves, if you really just, if you let yourself extend your limbs and move them around a bit so you break up that thermal layer, that's the tough way to do it. So when I see people on social media getting in and they're like really tough and trying to look hard.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  33. Because you're breaking up that thermal layer. And then when you get out, you'll notice a lot of people huddle or they'll grab the towel. In general, that's me. I'll get back. I'll get into the sauna. But if you really want to stimulate the big increases in metabolism, you stand out there and you dry off with arms extended in open air. And as that water evaporates off you, it is really cold. But your body is forced to activate a number of the warming programs related to metabolism. This is the beautiful work of a woman named Susanna Soberg, who's Scandinavian, she published this paper last year in Cell Reports Medicine. And so I call this the Soberg principle, which is if you're doing ice and heat for whatever reason, it doesn't matter if you end on heat or cold. But if you're using cold specifically to stimulate an increase in metabolism, end with cold. That's the sober principle.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  34. That you're warming yourself, the really bold way is to get in and continue to sift your arms and legs. And it ends up feeling miserably colder.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  35. There's a struggle. Heat and cold pull you down from the inside. You have to, I mean, there's a reason why the screening process for they call it seal training, but it's really screening and training involves cold water is because, you know, if you're in the heat too long, you'll die or damage tissue. In cold, you can do it quite extensively before you die or damage tissue, but it is stressful. I was going to say one thing that I sometimes enjoy seeing these social media posts where people get into the ice bath and they'll look really stoic, like they're really tough. But actually, that's the wimpy way to go through it. When you get into cold water, if you stay very still, you develop a thermal sheath around you.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  36. Has to be done. A podcast that was done from Asana continuously would be really interesting. Like you could call it like the pressure cooker or something. Oh, I mean.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  37. The moment I get into those, I have a hard time catching a full breath. It burns. They've got a cold dunk that's like a shock. And then they've got a sauna, a wet sauna steamroom that's a little mellower. So the nice thing about a banya is you can kind of find your place. And then they do the plaza where they take the eucalyptus leaves and you can pay someone and basically you cover your groin and then they beat you with the leaves and it's supposed to bring the vasculature to the surface. I've only done it once. And frankly, I found it to be a little bit unnerving. I didn't really like the experience. But I'll try and get into a sauna as often as I possibly can, which is, you know, once or three times per week. And I try and do the cold. Exposure, shower, or immersion, but early in the day because it really wakes you up.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  38. Yeah, in general. Very old special. Yeah, I mean, to me, it just seems like just be aware. But nonetheless, the banyas have very hot saunas because they're Russian-owned. And in New York, there's one on the lower east side, but the Spy 88 place, they have some saunas that...

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  39. I'll have to read up on that. I read that somewhere. I suppose it's not required, right? For childbirth, but in all seriousness, in New York, I'll go to a place called Spa 88. And actually, Khabib's picture is on the wall. He goes there. And that one, it's clothing. They require clothing. I always just say that because it can be. Sort of more old fashioned in that way, I suppose.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  40. And so on. Whenever I'm in New York, and there's also one in San Francisco, although the one in San Francisco is clothing optional, just to warn people, there's a place called Archimedes Banya.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  41. Come on when you experience them in the same way, I like to say this that when you get into a cold ice bath or cold shower, the increase in epinephrine and dopamine is two to three hundred percent. These are huge increases and they last many hours. This is shown because lately I've been getting a little bit pushed back on Twitter that which is an interesting place. People say, well, that's just in mice. No, all the studies I just referred to are all done in humans, men and women, fairly broad age ranges. So you want to be uncomfortable in the cold. You want to be uncomfortable in the heat. This is why I'm not a big fan of infrared saunas, because they only go up to about 160, 170 degrees. Infrared light and far red light of all kinds has been shown to be beneficial for wound healing, acne, skin, eyes. There are even guys now putting on their testicles because it can increase testosterone and sperm production.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  42. With the sauna, it's the same thing. How hot to make it? Well, don't kill yourself, obviously. Be smart. If you're pregnant, you shouldn't be doing this anyway. But it's very clear that what you need is the release of something called dinorphin. We have endorphin, which makes us feel good. It binds to these mu opioid receptors in the body. You have dinorphin, which is the terrible feeling that you get when you're in really hot temperatures. It's also the terrible effect that alcoholics feel when they are in withdrawal. You feel agitated. You want to get out. It's really unpleasant. It's dinorphin binding to the so-called kappa opioid receptor is that's what you're trying to trigger. When you do that, a number of things happen. You set off heat shock proteins that go repair broken proteins and misfolded proteins. It also makes it so that later endorphin binds its receptor more strongly. So when you have this uncomfortable experience in the heat, you literally feel better in real life when pleasurable events.

    2022-04-17 · Lex Fridman Podcast · #277 – Andrew Huberman: Focus, Stress, Relationships, and Friendship · IDENTIFIED FROM THE TRANSCRIPT · source

  43. Okay, great question. People always ask how cold to make the ice bath or the cold water or the shower. You want it to be uncomfortably cold, meaning you want to feel like I really want to get out, but you can safely stay in. And that's going to vary by person and experience with it.

  44. Stocking cap and wrap yourself in plastics underneath all that and go for a run. But don't please nobody die of hyperthermia. I mean, you can die of warming up too much.

  45. So, 30 minutes a day is better than four times a week. Four times a week is better than two times a week, and two times a week is better than one. And the reductions in mortality are really impressive. If you get into a sauna the way I just described, not the two hours a day, but 30 minutes twice a week or three times per week, you reduce the likelihood of dying of a cardiovascular event by 27%. If you do it four or more times per week, you reduce the probability of dying by 50% of a cardiovascular event. And in these studies, they rule out other things that people are doing, smoking. They even ask them, do you live in an apartment? Are you in a happy relationship? Like they evaluate other potentially confounding variables. Now, for people that don't have access to a sauna, a hot water bath or hot tub is going to be your next best bet. And if you don't have access to that, do like the wrestlers do, which is, you know, put on two sets of sweats and a hoodie.

  46. For maximum growth hormone release, don't do sauna more than once a week, but get into the sauna for 30 minutes as hot as you can safely tolerate. So probably for you, it'll be 210 because I suspect you'll be on the high end of things. Then get out for five to ten minutes, no cold exposure, get back in the sauna for 30 minutes. Then they had them do it again, out for five minutes, back for 30 minutes, out for five minutes, back for three minutes. They had them do two hours of sauna exposure to get that growth hormone release. Now for the reduction in likelihood of dying of a cardiovascular event, stroke, or otherwise, the more often you do sauna, the better. So if you look at all cause, all cause mortality or death due to cardiovascular events, and you look at sauna use frequencies using the same parameters, 80 to 100 degrees centigrade, one to seven times per week, basically the more often you get into the sauna for 30 minutes across the week.

  47. So, there are three ways you can do sauna that I can just toss out as brief things. If you want to get a really big growth hormone release for sake of metabolism, fat loss, you're training really, really hard in jiu-jitsu and you want to recover, you don't want a sauna too often because the study that identified this massive 16-fold increase in growth hormone, they had people do this. It's crazy. They got into, okay, temperatures are 80 to 100 degrees centigrade. So that's 176 degrees Fahrenheit to 212 degrees Fahrenheit for five to 30 minutes is the typical ranges that people work in in these research studies.

  48. Didn't have a tie on, but you had all the look and seriousness that you do now. So clearly nature nurture, clearly you were born with that.

  49. Because in Russia, they actually did this for a long time. They thought that it would, and indeed it does build the immune system to expose babies to the cold.

  50. Just regular life. Yeah. And I should mention that cold showers after training don't seem to short circuit the training effect to the same extent that immersion in cold water does. And that really speaks to the fact that cold showers, even though they can provide some of the adrenaline for the mental effects of like, oh, I have a lot of adrenaline in my system from a cold shower and I can remain calm. There's utility to that. It's not going to have the same metabolic effects or other positive effects that cold water exposure has been shown to have. And that's unfortunate because most people have access to cold showers. Not everyone has access to a cold dunker and ice dunk. But here in Austin, you have this place. And no, they don't pay me to say this, but I always like going into this place whenever I'm in town, this place, Kuya. And they've got a sauna and a couple ice baths. And they even have those salt tanks that you can float on the surface.
