The problem here is that the original statistic is not being stated properly. The original statistic made many years ago was that 50% to 70% of body heat is lost thru the head, neck and shoulder areas of the body. The solution to prevent this was and is to put on a good hat, close up your coat and/or wear a scarf. The heat-loss doesn't come from the head only; but from the overall collection of heated air trapped in the clothing layers rising from the "chimney effect" caused by an open neck,head and shoulder area allowing all this heated air to escape thus chilling the body. Don't forget, however, that when engaging in strenuous activities the body will produce greater amounts of heat, requiring you to open these areas for proper ventilation and then re-closing them when activity ceases.

This is useful info. Thanks for finding it. I remember hearing the 90% thing and laughing my ass off, but I still imagined that you lost more heat though your head. This is useful info.
