Cold Exposure: Ways the Body Loses Heat - Alberta

WebColder temperature, higher wind speed, and wetness will all increase the body’s rate of heat loss. Because water increases the efficiency of transfer of energy compared with air, exercising in cold and wet conditions ( e.g., swimming or exposure to cold rain) may be more dangerous for hypothermia than in freezing but dry conditions ( 2 ). Clothing Webof body cooling. In contrast to air, which is considered an effective thermal insulator, water is an excellent conductor. Specific heat of water is about 4,000 times that of air, and the thermal conductivity of water is approximately 25 times that of air. As a result, heat loss may be 25-30 times faster when immersed in water such as during ... jewish dating websites orthodox https://meg-auto.com
