Ever heard of hamam?
[1] https://en.wikipedia.org/wiki/Sauna
Hammam's temperatures are around 40-50 degrees Celsius and humidity is close to 100%.
These are very different conditions, with very different body response.

:-D
The last time it was held, a Russian died and a Finn ended up in hospital with severe burns.
The problem is that staying as long as possible in a sauna can be fatal.
A different Finn won.
One used to read regularly (like a few times a year) about someone who came home drunk and went to (electric) sauna and passed out... and died.
Saunas in new construction now all have timers.
Which makes it absolutely unbearable. By the way, that combination of temperature + humidity will cause severe hyperthermia (which can be deadly) faster than people think.
