Winter Myths debunked

I remember when I was a school student, about the TV programs and even some of our teachers telling us why wearing a cap in the winter is a necessity. The argument was that, most heat from the body is lost through the head. Of course, it was plausible since the scalp has the surface area to lose body heat.
But I learned today that this is actually a myth. Researchers have now found that any part of the body that has been left uncovered will lose heat. (BBC Report)

Scrutiny of the literature shows this myth probably originated with an old military study in which scientists put individuals in arctic survival suits (but with no hat) and measured their body temperature in extreme conditions.

If the experiment had been done with the participants wearing only swimsuits they would not have lost more than 10% of their body heat through their heads, the researchers said.

Hangover cures
Scientists have also found that there is no cure for hangovers except to "not consume alchohol".
Now, that must be something most households in Kerala have already found out, even if unscientifically documented.
