The exact temperature that's tolerable depends on the sauna, but can exceed 100 degrees C for dry saunas. Air has comparatively little heat capacity, so even at those temperatures, sweat can cool your body fairly efficiently (feels pretty toasty, though). If you add moisture to the air (steam sauna), that temperature becomes unbearable quickly, so those are at lower temperature.
- lmilcin 5y agoIt becomes unbearable not because of heat capacity but because of inability of the body to expel heat. When outside temperature is equal or higher than body temperature the only way to expel heat is through sweating. For this the air must by dry enough (wet bulb temperature less than body temperature). https://en.wikipedia.org/wiki/Wet-bulb_temperature https://en.wikipedia.org/wiki/Wet-bulb_temperature If body can't expel enough heat it results in eventual death.
