Question

What is the percentage of heat loss from the skin?

Answer 1

Heat loss from the skin:

1. Convection, heat transfer, radiation, and sweat evapotranspiration lose approximately $85$ percent of body heat through the skin.
2. Heat loss can happen through heat transfer from the skin to the stack of still air surrounding the body, convection to the free air layers, radioactivity from the skin, and water evaporation.
3. Heat causes vasodilatation (enlarge), allowing significant quantities of blood to circulate close to the surface of the skin, where heat can be set to release.
