When I'm in a hot place, my ears get hot. How is this and what do I do?

Answer 1

It is a mechanism for your body to lose heat, the ears act like little radiators, ( which is why they get cold in the winter) so the body dilates the blood vessels to send more heat to the skin and it is lost in sweat, convection of air, and radiates away from the body as well. Don't worry about it.
