Sauna Benefits for Longevity and Performance Doctor's Experiment and Scientific
00:0030 minutes 30 days one doctor and strength coach in search of optimal longevity what if sitting in a hot room for 30 minutes a day could improve your heart health improve your exercise recovery and maybe even add years to your life well we're putting that to the test I'm measuring my heart rate heart rate variability blood pressure blood work and so much more before and after sauna and steam room exposure to see if those markers improve but we're not just relying on my results does the science actually back up sauna and steam room exposure for for health Improvement and if it does how do we optimize our sauna and steam room use to get the most for our health let's find out what made me want to do this experiment in the first place is finding some insane studies looking at the effects of frequent Sona use there's a series of studies that was done on 2,000 Finnish men and in Finland almost everybody sa us at least once a week but up to four to seven times a week and what these studies found was that the men who sounded four to seven times a week compared to those that only sounded once a week had much much better health outcomes one study looked at
01:00heart disease and all causes of death what they found was that the men who Saed four to seven times a week had a 50% lower risk of death from cardiovascular disease compared to those that only Saed once a week and those men who Saed more frequently also had a 40% lower risk of all causes of death compared to the men who only soned once a week that same study also demonstrated that if you sat in a sauna for greater than 19 minutes compared to if you sat in it for less than 11 minutes you're also going to reap health benefits those that sat in the sauna longer had a 52% lower risk of cardiovascular disease and a 24% lower risk of all causes of death and the benefits just keep coming when you look at further studies on these men they also demonstrated that those who sounded more frequently had a 66% lower risk of dementia and Alzheimer's disease and finally a different study on the same men also demonstrated that those who soned more frequently had a 77% lower risk of psychotic diseases
02:00compared to those that SAA less frequently here kind of demonstrating the potential mental health benefits of SAA and these are remarkable results so I wanted to test them on myself and see in 30 days could I reap any health benefits from sitting in a hot room every day and to set up that experiment I had to First decide what was my routine for son use going to be I looked back in time and kind of found that for thousands and thousands of years people have been using heat exposure to improve their health different cultures in different countries and different people have done it differently but the core value stays the same and that is being exposed to heat on a regular basis improves mostly cardiovascular health which leads to Better Health outcomes and better recovery and a better sense of well-being the most studied type of heat exposure is the dry SAA use in Finland the studies that we just talked about and these finnished SAA baths are generally about 176 to 194° F at only about 10 to 20% humidity however for
03:00ease of use convenience and cost efficacy I decided to go with something called a Sona box which is basically an atome more of a steam room compared to a sauna the sauna box basically gets up to 130° F but is 100% humidity so this is definitely more of a steam room versus the finished studies that we just looked at which used a dry SAA of only 10 to 20% humidity however there are reasons to believe in the studies that a steam room could provide just as good of benefits as SAA one study in particular looked at dry saas compared to steam rooms or the finished sauna compared to something that was closer to a sauna box with 100% humidity but lower temperatures what they found was that the steam room actually provided even more of a cardiovascular stress than did the dry sauna and because much of the benefits from heat exposure come from giving your body a heat stress and then adapting to it to provide Better Health outcomes it would stand to reason that a steam room then which provides a greater stressor could even provide Better Health outcomes so with that being said did feel comfortable using the sauna box
04:00or more of a steam room to get my regular heat exposure and hopefully provide me with Better Health outcomes however I still had to decide based on the studies how long should I be in the sauna and how frequently well what I ended up doing was using the Finish way of SAA bathing which is actually what they used in the study comparing the dry SAA and the steam room basically what you do is you get in the sauna for about 15 minutes then you get out and have some type of cold exposure for maybe about 5 minutes then you go back into the heat exposure for another 15 minutes and there you go 30 minutes per day so with this protocol in place I then had to decide which health markers was I going to measure over the next 30 days to see if I had any positive Health outcomes from regular SAA use well in the literature most of the proven effects of SAA are in regards to cardiovascular health first off is cholesterol there have been multiple studies that look at sana's benefits towards lowering LDL or that bad cholesterol so I went ahead and had my
05:00blood work taken before and after my 30 days of regular sauna use and here is my first Baseline lipid panel the next cardiovascular health marker that SAA has benefit on is blood pressure specifically there are studies that demonstrate you can have an 8 point lowering of your systolic blood pressure from regular son use so I went ahead again and measured my Baseline blood pressure with the intent of measuring it after to see how they compare the next thing I wanted to track with an aura ring is my Baseline resting heart rate as well as my heart rate variability or a measure of how well you shift into that rest and digest State compared to the fight ORF flight State well there's not a lot of studies on how regular Sona use affects this long term although there are a couple studies demonstrating how you do increase heart rate variability directly after Sona use so it'll be very interesting to see how these initial Baseline results are altered in the long term over that 30day period next also with the aura ring I wanted to measure how SAA could affect my sleep and there are definitely studies that demonstrate that SAA improves people's subjective sleep
06:00experience and there are some other studies that even prove that regular sauna use can improve measures of deep sleep so I went ahead and averaged my sleep score from Aura as well as my deep sleep and REM sleep markers to see how those would be affected by regular sauna use and finally I just wanted to subjectively measure how sauna would affect my post exercise recovery my performance in the gym Etc there are definitely some studies that demonstrate improved athletic performance as well as recovery post exercise so I wanted to see if this would also play out for me with all my initial data taken we jumped into the experiment and doing this experiment myself really taught me how heat exposure actually leads to positive Health outcomes the actual mechanisms as to how it does so the first thing I noticed when getting in the sauna was how difficult it was to stay in there those last 5 to 10 minutes especially near the beginning of the 30 days truthfully it feels a lot like you're ending a long run and this makes sense because a lot of the mechanisms as to how heat exposure causes long-term health benefit are similar to The
07:00mechanisms as to how aerobic exercise causes long-term health benefits basically this is due to a principle known as hormesis or basically your body responding to stressors and building you back up stronger than it was before so that if you arrive at that stressor again your body is able to defeat it how this works with heat exposure or with heat as the stressor is basically your core temperature starts to raise and your body doesn't like that so it tries to dissipate that heat how does it dissipate that heat well what it does is sends all the blood to the periphery it vasodilates or opens up the blood vessels near your skin so that all the blood can be sent there so that you can essentially then sweat it off and because it wants to get the blood out to the skin faster the heart also starts to beat faster so this is why when you're sitting in the sauna your heart is beating faster you're sweating your skin is flushed because you're trying to dissipate that heat your body is essentially trying to lower its Corb temperature so over time your heart then adapts to be able to pump more
08:00efficiently so that next time it can pump blood faster out to the skin also your blood vessels become more elastic more stretchy which is great for preventing plaque formation and heart disease in the future and these mechanisms are really why sauna steam room or any heat exposure has such great benefit on long-term Health outcomes an additional mechanism as to how heat exposure can improve long-term Health outcomes is through something called heat shock proteins in response to heat or other environmental stressors your body releases more of these heat shock proteins and these proteins are great at a few things which really help long-term Health one is preventing protein aggregation or essentially the clumping of proteins which is found in a lot of long-term disease processes specifically neurodegenerative diseases such as Dementia or aliners two these proteins also prevent muscle atrophy so you can imagine it could really help to do sauna post exercise or when you're unable to exercise to prevent muscle loss and finally these heat shock proteins are also directly linked with longevity the
09:00higher expression of heat shock proteins the longer the lifespan and what's super cool is as you are continually exposed to heat in SAA or steam room your body will continually increase your heat shock proteins and this effect will not just drop off the moment you leave the son or leave the steam room your body will actually continue to express more heat shock proteins than it did prior to when you had ever been in the sauna so that principle of adapting to stressors and also the increase in heat shock protein are probably the one in two mechanisms as to how heat exposure can improve your health outcomes and if you get in a sauna or a steam room for any amount of time you'll quickly notice the next mechanism as to how it improves health and that is through sweating I was shocked at just how much I sweat sitting in that steam room and I know because it's a steam room a lot of it will feel like sweat but it's actually just condensing water but you are still sweating a lot in the studies proed that for a dry sauna you're losing up to about 1.6 PBS in a 45 minute period and for a wet sauna or a steam room you're
10:00losing about 8 lbs in a 45-minute period and this amount of sweat is great for detoxification there are a lot of studies that demonstrate that you lose a lot of toxins that are built up in your body through sweating them out one is heavy metals there are studies that prove that there are a decent amount of heavy metals that are excreted through sweat the same goes for BPA a toxin found in a lot of plastics also the same goes for phalates or a toxin found in Plastics cosmetics and food products also the same goes for organophosphates found in a lot of pesticides which we then eat on our food and finally we also sweat out metabolic waste or Ura or ammonia so the more you sweat the more likely you're able to detoxify from all of these toxins coming in from our environment on a daily basis outside of just learning about how SAA actually works and the mechanisms as to how it improves your long-term Health doing this experiment helped me learn more strategies in regards to really optimizing the sauna experience the first thing that I really Str strugg with initially was hydration because I
11:00was sweating so much I really found that I was dehydrated initially my resting heart rate started to increase I started to perform not as well in the gym my fingers and my feet were just so dry so I really then had to focus on replacing all my water that I lost from the sauna and again with losing about 8 lbs per sauna session I had to really increase my fluid intake 16 to 24 ounces immediately after that sauna session to maintain proper hydration throughout the day and for my skin I also found it super important to to moisturize my hands as regular heat exposure can definitely damage your Skin Barrier another thing I really had to focus on was my gut health initially I had some problems with bloating or abdominal pain immediately after my SAA session which this makes sense the same can happen after aerobic exercise basically what we talked about with all those blood shifts where it will now shift to your extremities instead of to your gut now that also will help your gut become more leaky and because you are applying a stressor now you have an increased cortisol response which can also cause
12:00your gut to be leaky so if you're experiencing any gut symptoms when using the sauna I'd highly recommend before you get in the sauna having glutamine vitamin C and vitamin E all which are great at inhibiting the inflammatory response that can come with heat exposure or with exercise and then lower the risk of leaky gut causing that gut inflammation and then the symptoms and finally in regards to tips to optimize the benefits you get from SAA use I would definitely recommend including a regular exercise habit with your sauna use there's a lot of great studies on how sauna plus exercise really provides a synergistic effect on your cardiovascular health and because it can also improve your recovery like we talked about earlier I would recommend that you do your exercise first and then have your sauna session after for the most optimal effects from your sauna experience so with all those learnings and optimizing my sauna experience did it actually improve my health markers in only 30 days for cholesterol from the blood work we found that my LDL decreased from 90 to 85 and my
13:00triglycerides decreased from 53 to 38 so for cholesterol I would deem this a mild decrease but still significant and I'll count that as a win for blood pressure this is where I found the most effect my blood pressure went from average of about 133 over 75 to about 127 over 71 and I found this to be incredibly significant as someone who has borderline high blood pressure this was a great effect for me and is truly remarkable decrease for something that is not a medication after all blood pressure medications on average lower people's blood pressure by about 9 points over 6 points so to have a lowering of six points over four points from just this intervention over 30 days is a huge win in my B for my resting heart rate it actually increased from about 43 to 45 and this was a statistically significant increase although still a very small increase my hypothesis here is that it increased due to again not being hydrated initially in the experiment and this essentially leading to prolonged periods of stress
14:00throughout the day my heart rate variability on average went from about a 73 to a 72 which was no change statistically and my sleep measures also did not change measures of Deep Sleep REM sleep as well as my overall sleep score all did not change statistically before and after Sona exposure and what about my thoughts subjectively how did it affect my post exercise recovery and my performance in the gym well for me I didn't have too much of an effect truthfully I feel like I normally have pretty good energy in the gym I'm not too sore normally so I didn't notice too much of an effect here but I would love to hear how SAA or steam room exposure helps you in these categories in the comments below so overall while SAA didn't really affect my sleep heart rate or heart rate variability or really post exercise recovery or performance what it did really affect was my markers of cardiovascular health in only 30 days I noticed a huge decrease in my blood pressure and a mild decrease in my cholesterol So based on this and all the studies we talked about I am definitely a sauna believer and if you're impressed
