The Sauna Might Actually BOOST Muscle Growth and Health
00:00there's some recovery data like on it where in general subjective recovery scores soreness those sorts of things seems that just be better if you use the sauna if heat exposure and saunas turn out to magnify the growth response Scott we're turning the gym up to 90 you already do man shut up what is the effect of the sauna and heat exposure on muscle growth because cold exposure we already know fucks that shit up maybe I'm wrong but cold exposure not pretty clear for like hypertrophy man at this point like it especially after training right right proximal to the resistance training session it's just doesn't look good yeah so do not cold plunge after you weight train at the same like gym or whatever if you want to yeah grow muscle what fuck are you training anyway right EX you list every
01:00benefit of resistance training like unless you're resistance training for your soul only um what about the sauna bro what about heat yeah it is an it's an interesting well first off I I'm surprised by the lack of evidence there's not there's barely any evidence so not a ton of people are doing the studies on like if we put people in saunas after training versus not how much more jacked or less jacked we get yeah so I that's the first disclaimer is like we don't have good like longitudinal well-powered sure good research on it what about from what we do have what can we surmise and I think this is important where it's like well let's look at uh established phenomena and one it's like in particularly in Finland uh they love the saas they do and when you compare sauna users more than you know four times a week seems to be you know three or four times a week 20 minutes-ish hot though like 170 uncomfortable yeah to like maybe as high as like 90 what the fuck all right hot
02:00uh those individuals to individuals who don't use the sauna in terms of like all cause mortality risk Ian it's like 40 50% different I don't like that um a glomeration of studies in the inference at all because I don't because it's very difficult to parse yeah health health uh practices aside you could just be screening for conscientiousness at that point we already know a sh and in uh some cultures the sauna attendance is a thing that people do when they're very health conscious and so is it really the SAA or it 100% um and so like you know people who when they're in the second grade have all their colored pencils lined up by color on their desk orderly make more money when they grow up but it's it because of the colored pencils no it's just cuz they were that person that organized Sy arounds they're nice I hated them and I can never organized shit that's why I'm
03:00dirt poor um so I okay so but but but as a scientifically minded person I have to say the research is very interesting and it could very well be that something about the sauna enhances longevity but we also know that things that enhance longevity like caloric restriction and like endurance training or dog shit for muscle growth so do we have to be suspicious now that the sauna is bad for muscle growth and mechanistic grounds then again I saw a recent one study that Illustrated that exposure to heat did trigger some hypertrophic mechanisms what do you make of that we're working with a like I say that was the first disclosure right is like already in a limited body of evidence there's limitations of I mean any like all cause mortality research we there's so many potential confounders I think there are there's some really well controlled things that we've learned though like smoking is not going to be Health promoting
04:00yeah the yeah the all cause mortality risk data on that I feel pretty confident pretty confident yeah um not so much with the sauna right um okay let's let's and just to be really clear if you compare the the research on cold plunging after a resistance training session I mean it's consistent right from acute measures of muscle protein synthesis to like using MRI to look at muscle volume after weeks of doing it you know we're talking like 40 50 degree water for like as little as 10 minutes after a session can really knock that hypertrophy response down down substantially not out but down down down maybe 30% 20 30% oh fuck really that's a lot Scott did you hear that shit you give up 30% of your growth cuz you dipped your balls in a fucking icicle fuck that oh it's that's interesting right okay and so it's like well why and I think that's informative we start thinking about the sauna okaye
05:00continue because one reason at least one reason at least and this has been measured there's some research out of Leon Roberts Australia um where they've looked at like temperature skin temperature changes perfusion arterial flow there's some vasil constriction there right like when we're really cold the uh vascular response is to shunt flow to other regions of the body to direct it to keep our temperature regul yes your body thinks it's dying of the cold and so it pulls everything into your heart liver kidneys Etc and your fingers and your biceps to be honest or just like whatever yeah and some people think that that's one of the reasons why it's Health promoting we we'll just leave that there for a second but okay so if it's blood flow mediated again go back to capillary densities with response uh variation for hypertrophy so if we're if we're blunting blood flow to the muscle right after the training session and that seems to really decrease the muscle
06:00protein synthetic response the growth response over the course of weeks well what if we what if we enhanced it mhm right what if we increased blood flow by putting you into the sauna yeah right because it's the opposite vasil dilation um and I think then you get into like well what is it brownie in motion right heat it's movement it's movement of stuff all all the molecule and it's like well are we perhaps encouraging uh the interaction of um ribosomes and some of those the molecular machines that are involved in instigating the initiation right of translation of those mrnas sure from heat it justes make some assumptions though I will say your body's pretty good at keeping your temperature well I guess the core temperature stays about the same yeah the core temperature but the peripheral temperature even in large groups of muscles can change pretty pretty
07:00decently okay so okay never mind I I you and I together refuted my stupid idea I had in my head where I was trying to be a bit cynical and saying like look like your muscles are still not fucking ice cubes when you're done training and like how much more heat can we heat them up to by getting into a sauna I will see the huge benefit of a sauna now I'm thinking about this I'm thinking maybe maybe we'll Scott we got to install a sauna right in the gym because bro with our gym lighting and the fucking getting out of the sauna bro if you get get out of s a fucking chest and tricep pump you got veins up every fucking it's I know for no other reason just pictures bro exactly man um so yeah I think those are some reasons uh but then there's an interesting class of proteins man and there is there's at least one study uh that and to be clear there's no study that I'm aware of that shows that if you do the sauna after you resistance strain for a period of weeks that you grow more muscle so of folks watch this Channel
08:00people get on it you you want some money hit up RP just kidding please don't do that that's not my problem really I don't do customer service no but seriously it would be fascinating to see and it's not a hard study to do to be honest one group like is told to just chill in the sauna and one group is told to chill in the sauna except they never fucking turn it on or two different temperature conditions that way you obviate any psychological stuff mhm right yeah so we need to do that yeah uh study what about the the pro pro what is it heat shock prot the shock part really makes it shocking I know the protein are like ah yeah it never like C say too amaz me some of the names of like molecules they're so funny there's one called son of sevenless that's so sweet people who discover shit just have cart blanch to name it if I discovered a molecule instantly dildo molecule next like Mike it's not even shaped like a dildo I'm like you just don't have any imagination anything's a dildo if you try hard enough yeah Scott says it's
09:00true you guys man oh man um okay but we promise your microphone that you're close to right now has never ever been used for that function this several past hours for sure good to know um yeah dude so those things seem to be like molecular chaperon they seem to help proteins go where they're supposed to go now why uh God knows I mean it's it's a little I would say misunderstood um but that seems to be their role yeah um to we have this synthesized protein and heat shock proteins seem to kind of Usher it to the cellular compartment that it's supposed to go to um and so that's interesting very and we have evidence that people who use the sauna like if you take tissue they seem to have more of those heat shock proteins Heat
10:00so like I think there's at least a couple good reasons why the sonuna could be an adant uh to help with promoting muscle growth alongside a potential and I use this word carefully detoxification um there's I know I know I use it very carefully Q hipsters I know um but there is evidence that in Sweat Right you find things that are probably not great for us us to be present in our bodies now of course toxic load makes a difference right exposure and so but clearance can be a cool thing right and it's you're chilling it's not like we're talking about that's so important right the RP hypertrophy app comes with dozens of pre-made programs from two days of training per week all the way up to 6 days of training with specialized programs included for shoulders arms chest back legs abs and glutes each one with male and female options you get them all and can use them as often as you like even building off of them to
11:00make your own customized versions for only about a dollar a day click on the link in the description of this video to get started so as long as you're psychologically comfortable in a sauna what my personal recommendation if you want to try this out at home let me know if you think this is decent if you have access to a sauna like you know a lot of people have sauna access in their gym after you finish a hard session get your carb protein fluid and electrolyte Shake bring it in with you sip on your shake and chill in there for 10 20 maybe minutes or something like that and really make sure you're in a posture that's relaxed and if you just hate being exposed to heat probably not good for the stress response but if you can just chill maybe get some headphones going or something like that it might be worth a try to see if it has some kind of beneficial effects because the um kind of peripheral reasonings is starting to
12:00get interesting mhm what do you think yeah well and there's some recovery data like on it where in general subjective recovery scores um soreness those sorts of things um sense of you know perceived recovery seems to just be better if you use the sauna interesting and like when you compare the the potential negative effects from cold plunging from the body of literature on that to the uh po negative effects of sauna it's kind of polarized polarized opposite my only reservation well it's twofold one no direct data and like you know don't put your faith into this just yet I'm not installing a sauna in my gym just yet but it was like three or four well-controlled studies and making more jacked I'm putting a fucking SAA in the ASAP um my only reservation is um your body absolutely Ador comfort and homeostasis and after massive homeostatic disruption that is training I have good reason to believe that the
13:00next thing you want to do is be as comfortable as possible and maybe accessions into both low heat High cold and high heat environments are maybe both different versions of the wrong answer it's kind of like asking a person like do you want to spend the next 12 hours in total fucking Silence with no one talks to you or is even around or do you want people yelling at you like can I get just people like coffee shop ambiance like no but that's what most people like best MH that's my only reservation I will say like if heat exposure and saunas turn we're turning the gym up to fucking 90 up and I mean that's you know even like doing a few minutes before a session sometimes I like to do that dude just to warm up that's a great warm up it accomplishes the warming for you um I will say for folks who get carried
14:00away by my 90° gym comment don't do that there is compelling reason not to train in a high heat environment your performance will go down like crazy uh Jared feather and I travel around the world doing seminars and stuff a little bit and um him and I have had some sessions in Australia and in Thailand where we both look at each other and we're like we have 30 minutes to crush quads until we can't do anything anymore because there's just not that many fluids in the world to put back into your body just excessively high heat does not work from a performance perspective but if you can do the high heat just before for warming up or the high heat just after for uh that extra boost for growth maybe then there's something to it another thing really quick what do you think about this the internal temperature of your working muscles while you train is way higher than Baseline is that part of the hypertrophic signaling Cascade
15:00H my biceps get hotter when I train them is that part of what makes them grow or do we just not know enough cuz heat shock proteins I don't know yeah I mean and I would say that's one of the and um Dr quindry who's at the University of Montana has I remember he he had some done some work on on this um at least taught us an advanced exercise physiology too at Auburn I remember we had a whole section on this um and my understanding is that exercise in general tends to increase the abundance of heat shock proteins and like if you if we had a group of 100 sedentary individuals and 100 people who you know had exercised for years and we pulled muscle tissue and we just looked at how many heat shock proteins were present even a baseline yeah just cross-sectional analysis on that yeah wow mhm that's trippy all right so tldr give the SAA look but the cold plun you got
16:00to Drake that shit because it's not going to help you out [Music]
