It may be hard to believe, but most cases of hypothermia reported in the U.S. each year are not reported in the frosty North and Northeast but in the warm stretch of the Sun Belt.

Discover magazine says Florida has more hypothermia victims each year than Minnesota, where winter often means temperatures of 40 below. Researchers think the high rate of hypothermia cases in the Sun Belt is the result of Southern sun worshipers not having the experience to cope with a sudden chill.
