How much heat do you typically lose through your head.?

Question

Ok, how much heat do you lose through your head? I always heard it was 80 percent, or in that neighborhood.

Answer 1

40 to 60 percent. depending on the weather, how sick you are, and how much you are exercising.

Answer 2

Here is an excerpt from an article about exercising in the cold It says 50% at the freezing mark.

Environmental factors, including temperature, wind and whether you're exercising in the air or in the water. Each of these factors plays a role in the body's ability to maintain a comfortable temperature during exercise.
Insulation

Although many people aspire to have a lean figure, people with a little more body fat are better insulated and will lose less heat. Clothing adds to the insulation barrier and is clearly the most important element in performance and comfort while exercising in the cold. One study showed that heat loss from the head alone was about 50 percent at the freezing mark, and by simply wearing a helmet, subjects were able to stay outside indefinitely.

Answer 3

I think it's true, and demonstrable, that large amts of heat
are lost from the body through the head, in cold climate.
A hat or cap, is greatly helpful in preventing that.

Answer 4

Alot...Like in the high 80% tile. When I run in the cold I wear shorts and shortsleeves, but where a beanie and it keeps me warm.

Answer 5

I remember that it was a lot, it was more than half though, I think.
