People in very cold temperatures protect themselves from the cold. No one lives in a sauna. Few live where it gets much over 40°C, those who do typically protect themselves from the heat as much as they can.
It’s probably more true that humans live between 0 and (low humidity) 40° without protection, but neither of those close in time, it takes adaptation to tolerate either end of those extremes
That wasn’t the point though… -40 to 80 is the APPROXIMATE range a person would want to describe in terms of “oh it’s twice as hot/cold as yesterday”, which is the whole point of the exercise, not to determine at what temperatures humans use protection against the weather, because guess fucking what, we protect our bodies even in optimal temperatures and weather conditions! Or do you walk around fully naked when the weather’s just right?
