The Short Answer
you make air hotter and wetter. Yes you, you stinky human. You're sweating. you're producing heat. These things move from you to the air. But they move slower, the closer you are to the heat and moisture of the air. Heat and moisture transmit more readily to the air the greater the difference.

And so your body can move heat and wetness to it faster. Thus cooling you.
