Scientists have this week revealed that the old adage that most of your body heat is lost through your head is just a myth.
According to a paper by the British Medical Journal published this week, many common beliefs, including the usual winter advice about wearing a hat in cold wear, are just myths.
Apparently the evidence that this myth is based on was printed by the US Army some 30-years-ago in a survival manual, which recommended hats because “40 to 45 per cent of body heat” is lost through the head.
The scientists claim that there is no reason to suspect that a large amount of heat is lost through the head and that, in fact, body heat is lost according to exposed surface area. It finds that the face, head and chest are sensitive to temperature change.
