Indeed, humidity matters a lot. Most our saunas here are löyly (in Finnish) saunas, so you get a rollercoaster of dry - humid - dry cycles. Once you get to 100+c and throw a good amount of water on the stones, it can get quite challenging to endure :)

Everybody has their personal preference of course. For me, the sweet spot seems to be a moderately humid sauna at 93c. At that point, the löyly is not too harsh yet but is still hot enough to make you feel alive :)

I also prefer around 90-100c with swings of humidity. I think it's most exciting exactly because you can make it temporarily more intensive with the "humid wave".

It's the most popular type of sauna - "the sauna" for a reason.
