Body heat escapes from all of your body. It escapes more in places where we sweat more often, such as the armpits and forehead. It escapes when we blush as the blood is closer to the surface of the skin so heat can escape easier.
The human body is usually hotter than its surroundings. As a result, heat is transferred to the surroundings. All three methods to transfer heat (conduction, convection, radiation) can be involved here.
Heat leaves your body by increasing blood flow to the skin. From that point, sweat droplets are created where heat loss is greater than dry skin. The convective (wind) and evaporative (the energy of water vapor evaporating from the skin) causes the blood and body to be cooled. That is a basic way to lose heat in a dry environment with skin showing in healthy individuals.
We lose body heat from every part of our bodies, but we lose the most from the head, typically.
In hot climate the human can have perspiration at the rate of one litre/hour. Lot of heat is released from human body by the evaporation of this much fluid.
by exhaling
Humans produce heat in order to keep warm. This is done by the body using its caloric reserves such as glucose and glycogen to make energy for the integumentary system to burn and thus heat up the body. If the body doesn't do this, it could undergo hypothermia and freeze to death.
All of your body heat would escape and you would die of hyperthermea. Heat escapes the most through your head and feet. <><><><> Too hot, you have hyperthermia, commonly called a fever. Too low, and you have hypothermia. If the internal body temp is too low or too high, organs in your body cannot function, and you die.
If your talking about YOU changing body temperature, then that's impossible because your warm-blooded; meaning that you produce your own heat. But other animals: such as fish, reptiles, and amphibians are unable to produce their own heat, so they rely on the outside temperature to regulate their body temperature. This is why snakes usually lay on rocks in the sun during morning, they are warming their bodies. Then during the heat of the day, they escape to a shady area to cool off.
Heavier humans have more body fat therefore produce heat to keep themselves warm.
In cold waters, assume the HELP position (Heat Escape Lessening Position). This is where you roll up into a ball with your chest against your thighs, while gripping your ankles. This will allow your body to retain heat longer, and could save your life if it gives more time for a ship to come by.
Alcohol helps heat escape the body.

Humans are considered heat engines by some. Others do not believe that the human body can be considered a heat engine. However, most do on account of the heat production that comes from the human body, as well as, the amount of work the body is constantly doing.
