Mostly False Global

The text claims that the head is the main thermoregulator, with 80% of heat escaping from it.

Infact verdict: Mostly False (20/100).

The claim that 80% of body heat escapes through the head is a common myth. Evidence from multiple sources, including health articles and medical blogs, indicates that only about 7-10% of body heat is lost through the head. This misconception likely originated from military experiments where subjects wore full-body insulation except for the head. Therefore, the claim is false.
