"You lose most of your body heat through your head"
FALSE 96% confidence
This myth originated from a flawed 1950s military study where subjects wore Arctic survival suits but no hats. You lose heat proportionally from any uncovered body part. The head represents about 10% of body surface area, so it loses about 10% of body heat when uncovered.
