Hypothermia: Nature's Cold Killer

Examines the human response to cold, symptoms of hypothermia, and various emergency treatments. Highlights experiments conducted by Dr. Keith Cooper at Foot Hills Hospital in Calgary, Alberta, Canada, that demonstrate physiological responses to decreasing temperature. Explains how the body shunts blood from the outer to inner core (the heart, liver, lungs, and brain) in order to protect the most vital functions. Identifies the symptoms of hypothermia as loss of muscle control, irrational thoughts, and increased rate of breathing. Demonstrates different techniques for delaying a decrease in body temperature when immersed in water. Suggests various first aid treatments for individuals subjected to poor weather conditions on land.
