What's Perspiration?

Perspiration

Say: pur-spuh-RAY-shun

Perspiration is another name for sweat, the stuff that comes out of your skin through tiny holes called pores. Perspiration — which is mostly water — is how your body keeps you cool when you get hot from exercise or hot weather. So next time you sweat, don't sweat it! It's just your body's way of chillin' you out.
