TIL You don't lose more heat from your head than anywhere else on your body. The myth came from a 50's army field manual with some suspect experimental procedures.

Despite the myth that people lose up to half their body heat through their heads, we actually lose far less than that.
You're viewing a single thread.
To be fair this article isn't accurate either.
If you click the British Medical Journal link, it states that you'll lose about 50% through the head when clothed in -4C weather. This article would only be accurate if you qualify it by saying "nude in -4C weather, you'll only lose 7-10% of body heat through the head"
The article also mentions another experiment done about 20 years ago with swimmers and the same body heat measurements, with results showing that heat loss was correlated with area exposed. It's a poppish article but the background behind the myth was the big TIL for me
