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 “löyly” 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.
Huh why do they have 105C saunas in spas then?
Because they’re crazy I guess? Over 90°C the risk of lung damage gets pretty high I think.
