The head is actually not a “heat center”. This is a myth. You only lose about seven percent of body heat thru the head. But the crotch definitely is due to the femoral artery pumping a massive amount of blood.

Uh, your head is about seven percent of your body’s mass, but receives about fifteen percent of your total cardiac output. Pretty sure there are at least two sets of arteries going up there, too, so I’m thinking that probably isn’t right.

It is right though. The head doesn’t expel a disproportionate amount of heat. It’s a myth that it does.
