mild in what way? Do you live in death valley??? Have you ever experienced 100f? You can literally get heat exhaustion, and heat stroke from temperatures of 110f pretty easily if you aren't watching yourself, we remind ourselves of this constantly anytime it gets hot.
It’s slightly above my core body temperature. So yes, literally I experience it all the time.
to be clear, it's not slightly above, it's high enough that you're getting into fever range, a few degrees over that and it starts to become deadly. 105f internal temp is potentially fatal so.
the average body temperature ranges about 2 degree fahrenheit. 97f to 99f that's about the entire extent of that. 100F specifically is slightly over that in terms of general temperature experience.
Sauna. It’s literally boiled water. And it’s pretty safe for average human.
thank god, i was about to do hard labor in a sauna. Not to mention this is also a sauna, not direct infrared and UV exposure to direct sunlight. Not to mention the literal temperature of the environment around it, and the indirect reflected heating that you'll receive.
guess i should now argue that cold temperatures aren't dangerous because people do ice baths regularly.
