From Susan Davis on WebMD: The head only represents about 10% of the body’s total surface area. So if the head were to lose even 75% of the body’s heat, it would have to lose about 40 times as much heat per square inch as every other part of your body. That’s unlikely — which has been borne out by tests of college students who lost the same amount of heat whatever the exposed area.
“The real reason we lose heat through our head is because most of the time when we’re outside in the cold, we’re clothed,” says Richard Ingebretsen, MD, PhD, an adjunct instructor in the department of internal medicine at the University of Utah School of Medicine. “If you don’t have a hat on, you lose heat through your head, just as you would lose heat through your legs if you were wearing shorts.”
