- The human body loses heat through several mechanisms1234:
- Evaporation: Water evaporating from the skin when sweating.
- Radiation: Heat leaving the body similar to heat leaving a woodstove.
- Conduction: Heat loss from contact with cold surfaces (e.g., sleeping on the cold ground).
- Convection: Heat loss due to air movement (e.g., sitting in front of a fan or wind blowing on you).

www.columbiadoctors.org/health-library/article/col…There are four avenues of heat loss: convection, conduction, radiation, and evaporation. If skin temperature is greater than that of the surroundings, the body can lose heat by radiation and conduction. But, if the temperature of the surroundings is greater than that of the skin, the body actually gains heat by radiation and conduction.en.wikipedia.org/wiki/Human_thermoregulationFour channels by which heat is lost from the body include:
- Lungs: Heat loss occurs as a result of warm air that is blown out, which may be felt by softly blowing on the back of your hand with your mouth open. ...
www.medicinenet.com/where_do_we_lose_most_o…When the water temperature is lower than the body’s temperature, the body loses heat by warming the water closest to the skin, which moves away to be replaced by cooler water. The convection currents created by the temperature changes continue to draw heat away from the body more quickly than the body can replace it, resulting in hypothermia.open.oregonstate.education/aandp/chapter/24-6-e… Do You Lose Heat Through Your Head? - Cleveland …

Human thermoregulation - Wikipedia
As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid. High temperatures pose serious stress for the human body, placing it in great danger of injury or even death. For humans, adaptation to var…
