Why You Sweat — and What It Really Does

Sweat cools you down through evaporation — not through the liquid itself.
You have up to 3 million sweat glands working like miniature sprinklers.
Eccrine glands produce watery sweat for cooling; apocrine glands release thicker, odor-prone sweat.
Sweat is 99% water with a dash of salt and minerals.
It’s odorless until bacteria on the skin break it down.
Stress and emotion can trigger sweating even in cool rooms.
Sweating helps remove trace toxins, though your liver does most detoxing.
Dehydration limits your ability to sweat and regulate heat.
Athletes can lose several liters of sweat per hour in extreme conditions.
Every drop represents your body’s natural cooling technology at work.
