Best Answer

Sweating takes warm water from inside the body - to the surface - where it evaporates, taking the heat with it. Therefore we cool down.

What if you can not sweat?

When I first started exercise, I would sweat so much. After a few months, the sweat stopped, even I worked really hard. I started to drink a glass of hot milk or just hot water right before exercise, guess what, I sweat again! 2nd answer: You always sweat. It may evaporate right off, so you do not notice any drops of sweat. The exception is if you are suffering from sun stroke . . . your body cannot sweat any more, and you are on the verge of dying from being too hot.
