How does sweat cool us down?

Question

I always assumed the way sweat cooled us was how the water on the outside of our skin cools off and in turn cools the skin down however I don’t get why the air that cools the sweat cant cool our bodies especially if our skin can heat that sweat just as fast or faster than the air can cool it.

Answer 1

You are hot.

You sweat.

That sweat is full of your heat.

The hot sweat evaporates.

You just lost some heat because the heat was in the sweat. And the sweat just left you.
