Lasd02, thanks for the post & interesting discussion you have generated.
4. "If your feet are cold, put on a hat." Fact: We do not lose more heat from our heads than from any other portion of the body with the same surface area.
Based on what I've read so far during this thread the jury is still out on this one, but I do know one thing for sure...the few times in my life that I've needed to take a cold shower the part where I had to wash my torso & head was by far the most brutal. The hands, feet, arms & legs sure do not seem to affect our response to the cold water the same way that the torso, neck & head do. My gut feel on this would be this is a built in survival instinct that makes us greatly desire to get those more vulnerable parts out of the contact with life draning cold more quickly BECAUSE THEY ARE LOSING HEAT FASTER. But I have no scientific proof.
I think the study you have quoted screams for more research.
