Cold, wetness, and wind challenge the body to maintain core temperatures above 35oC (94oF). Heat loss or inadequate heat production elevates the risk of physical discomfort, hypothermia, or surface injury such as frostbite. Blood flow bears principal responsibility for maintaining peripheral temperature in cold weather and is the metabolic vehicle for the transportation of oxygen and generation of heat. The one adaptable characteristic that can contribute to …
