In a Sauna it can be 98ΒΊC, not the same extern temperature and body temperature. You'll die when your body temperature is over 42ΒΊC, but you can support way higher extern temperatures (for a certain time)

The hottest you should have a Sauna is 90Β°C.

I was in one the other day that was 118. My first time being in one so hot, and it was... surprising.

Just never been in that kind of heat before. It was oppressively hot, breathing felt heavy, and sweat was pouring out like a dripping faucet. Interesting sensations

Sounds like a sweat lodge. I don't know how hot they get those normally.

Did that at summer camp as a kid, but memories are distant so it's hard to compare. Prob similar, I vaguely remember sweating like crazy

[–] Zerush@lemmy.ml 7 points 1 month ago

Most also less, but it also can get higher. Always important the preparation before and after the session a cold bath, apart of an strict time control to avoid accidents, sometimes deadly.

Huh why do they have 105C saunas in spas then?

[–] princessnorah@lemmy.blahaj.zone 9 points 1 month ago (1 children)

Because they're crazy I guess? Over 90Β°C the risk of lung damage gets pretty high I think.

[–] boonhet@sopuli.xyz 10 points 1 month ago

To be clear, do you stay in the sauna the entire time? Because around these parts it's common to get in, splash some water every now and then ("leil" in Estonian or "lΓΆyly" in Finnish) and then get out after like 5 min to take an ice bath. At 100+ you probably skip the water.

I bet if you stay like 15+ minutes at once it's way worse for you because your internals have more time to heat up.

The term is "warm-blooded" but if the outside temp is above 37C then it'd technically be more accurate to say "cool-bloods" or something.

Endotherms vs ectotherms!

Holy fuck I did not know they were so hot, how does a human body even survive that for any amount of time.

[–] Revan343@lemmy.ca 13 points 1 month ago

Dry air doesn't conduct heat as well as humid air, and allows evaporative cooling through sweat
