Using the extremes of temperature that occur in a day’s skiing, this program shows the range of mechanisms through which the human body maintains a steady internal temperature and protects its vital organs: shivering, hair erection, and rerouting of blood supplies to conserve heat; increased blood flow to the body surface, sweating, and panting to lose heat.
