Your body is constantly generating heat. If that heat has nowhere to go, your temperature goes up and up.
You need to be in an environment that sucks heat away as fast as you create it - and if the external air temp isn’t cold enough to do that on its own, then you have to rely on evaporation of sweat to help shed the heat.
It’s the feature that let us become the dominant predator. We could track large game that is wounded until the collapsed from heat exhaustion. Yay sweaty humans!
It also seems like this is part of why there were so many powerhouses around the mediterranean, the climate there is just right that you can work a lot without melting, and warm enough that it’s comfortable to walk basically naked.
And it makes sense when you consider that humans evolved for a comparatively sedate lifestyle (even hunting isn’t going to involve sprinting that much) in subsaharan africa.
