Sweat is your body's way of staying cool. It plays an important role in regulating your body temperature when you are in certain situations including participating in strenuous activities or out in the sun for an extended amount of time.

Unfortunately, sometimes your body does not sweat enough to stay cool or when you do sweat, you may not be drinking enough fluids to replenish your body. In both cases, you may experience heat exhaustion.
