Also more complex models e.g. Stolwyck & Hardy's 25 node mode. Shell - skin temperature varies over a greater range than core temperature. Skin temperature depends primarily on environmental conditions. jessica montalbano

"WebbThe thermoregulatory balance is altered to favor heat gain mechanisms, such as shivering and reduced cutaneous blood flow, complemented by behavioral changes such as curling up in a fetal position and getting under blankets. These mechanisms persist even though body core temperature is higher than “normal.” " - Thermoregulation radiation cooling or heating

WebbRadiation is the emission of electromagnetic “heat” waves. Heat comes from the sun in this manner and radiates from dry skin the same way. Heat can be removed with liquid from a surface during evaporation. This occurs when a mammal sweats. Convection currents of air remove heat from the surface of dry skin as the air passes over it.
