@_bryan_johnson_: here's the science explained 👇 Inside every cell in your body are tiny machines called proteins. They make energy, fight germs, build muscle, send signals. For a protein to work, it has to be folded into a very specific shape, like origami. When proteins get crumpled or broken, the cell has a clean-up crew that fixes them. The crew is called heat shock proteins. They refold the messed-up ones and throw out the ones that are too far gone. Here is the catch. The crew is lazy. They only wake up when the cell gets hot enough to scare them. The trigger is your core body temperature crossing 102.4°F (39°C). That is fever-level heat. If you sit in a sauna and barely break a sweat, your clean-up crew never wakes up. When the crew does wake up, it does a lot at once. . Damaged proteins get fixed . Your cells handle stress better . Your mitochondria (the tiny batteries inside every cell) work better . Your body uses energy better . Possibly some protection against the brain diseases that come with age . Your body gets tougher at handling heat in general Here is the part most people miss. The sauna being hot is not the same as you being hot inside. The thermometer on the wall does not matter. Your body has to actually heat up. For me, it takes 31 minutes in a 200°F (93°C) sauna to cross the line. Your number will be different, especially if you have not spent much time in heat yet. If you sit in the sauna for 10 minutes and leave, you had a nice spa day but you probably didn’t hit the cellular repair threshold.

A Finn here ✋🏻 You’re still doing sauna wrong ❌ The sauna is to be done without any measurement systems and goals. You go with your buddies, you have a banter, maybe drink a few beers, dip into a lake, and just chill.

matthew3062 :

I have a built in rectal probe for my sauna chair so I can make sure I'm hitting the right temperatures each session 👍

ALFREDO :

how old is UNC btw🥀🥀

BigChungus_42069 :

Kortsu ✝️ :

The point of a sauna is to chill and relax

Janne :

if there is no water trowing on rocks its no a sauna

mark :

39°C btw

That one bro :

His eye 👁️

Ignacio :

dude baking himself for science and sharing tips. thank you!

akseli🇫🇮 :

as a finn with 5x his experience i can say its for relaxation 😭

Tjiosse :

The sauna isn't a performance. It's mostly for relaxation and such. Just go by feel

CRSDR :

as a finnish person (we invented sauna), i think it’s very racist to tell me how to do sauna… Sad to see world still so devided and hating on other cultures. Sauna needs to be around 200°F when entering. You old man still think racism is okay…

Barsan Andrei265 :

...no .. Finland sauna is the best

"ℑ"🤙 :

why not give that in Celsius? like why gatekeep it behind math 😭🙏

panupajari :

U are wrong. If u dont use sauna the finnish way ur doing it wrong. Suomi perkele ja torille

princeofgoteborg :

Remember me in 600 years unc

Veeti :

"200 sessions" rookie numbers

Repennakki :

He is still doing everything wrong.

kingaddelito :

Go out in the sun bro

ulmarr :

Finn here.. sauna is a temple or a sanctuary. also its not heat its the humidity. 60-80celsius and constant water to the rocks

ßàñdér🇪🇪 :

the point is to literally sweat✌🫩✌️

Steffeponken :

I will not have a vampire tell me how to use my Sauna

userpikey :

Why his eyes so red

Jermulaani :

You are supposed to throw water on the sauna stove to increase the air moisture because dry air is terrible at conducting heat. Hope this helps 😌
