100C° is not death, it is Finnish sauna temp. Really, Sauna competitions start with 110C°. Famously in 2010 one Russian competitor died, and the Finn who won had to be sent to ER.
Edit: didn't know that they actually haven't held any competitions after that.
Haha, sure, but there isn't much to know.
Sauna competition is that they go inside hot sauna and last one who comes out wins. They increase the temperature and throw water to the sauna stones. That humidity makes the temperature feel quite a lot harder (air is quite good insulator, which is why you don't boil).
In the competition quite often people got first degree burn injuries, which is quite crazy.
