Clothing
Keeping warm in Antarctica is not simply a matter of piling on
more clothes. In fact, overdressing can be as hazardous as
underdressing. If you get too hot, you sweat, which can lead
to freezing, because moist skin transmits heat almost 20 times
faster than dry skin. Similarly, if your clothes get wet, your
skin can lose as much heat as if it had no covering at all.
The best way to keep properly insulated is to wear clothes
that repel wind but allow both body moisture to escape and air
spaces to form between the clothing and your skin. Finally,
you must wear a warm hat at all times, since up to 80 percent
of your body heat can escape through your head.
