WebConduction (such as heat loss from sleeping on the cold ground). Heat is lost in air temperatures lower than 20°C (68°F). The body loses about 2% of its heat through air conduction. However, water causes more heat loss from the body than air does, so heat can be lost from the body very quickly when it is placed in cold water. WebThermoregulation is the body 's ability to balance between heat gain and heat loss. This is possible by four mechanisms, called neural and vascular control; heat production; heat loss; and behavioral control. Disrupted thermoregulation …
