Abstract
Humans have developed the technical capability to protect themselves, from a thermoregulation point of view, against almost any terrestrial extreme. With respect to the extreme cold, it is understood that the best technique to ensure survival resides in enhancing one's insulation, or reducing heat losses, by using a wide variety of new high-tech clothing and equipment. Excellent examples of the use of such technologies are displayed by winter Olympians, skiers, trekkers, joggers, and, in particular, polar adventurers. However, there are situations where technologic and behavioral strategies to increase insulation are simply not available, not appropriate, have lost their effectiveness, or have already been maximized. Faced with high rates of heat losses, survival would then reside in one's physiologic ability to maintain body temperatures via vasoconstriction and an enhanced metabolic heat production. This chapter focuses on thermogenesis during cold exposure, key factors that influence one's resistance to cold, hypothermia and its treatment, and finally implications for the winter athlete.
