Hi there!
There is a way that the human body cools itself, but it sounds so weird!
Did you know that when you sweat after doing something constantly, the sweat tries to cool the body down? It's true!
I learned this is physical science class, and we tested it for ourselves. We ran around a bunch of times around my old school and then we started sweating. Not too long afterwards, we started cooling down because of the sweat.
Weird, right?
Hope this helps!
Message me if you need anything else! :D
