How does sweat cool us down?

560 viewsBiologyOther

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.

The air will slowly cool the skin but moisture helps cool it faster because the phase change from liquid to gas requires energy that the molecules absorb and carry away when they evaporate
