The top of your head is where the heat ends up. The body cools itself by sweating, but also by redistributing the heated blood elsewhere. That's why, when I go out for walks, my feet end up overheating too. It will move the blood away from the core, and maybe also the head, where a lot of heat accumulates. Maybe if our drainage is too slow, we can't remove head heat fast enough by letting it drain out to be replaced by cooler blood from elsewhere. We're talking small fractions of a degree here, because the control is usually quite good.
