How does the human body stay warm?

Answer 1

Heat is generated in the body as a byproduct of metabolism. No process is 100% efficient, and heat is generated as a waste product. Muscle contraction uses ATP, and a portion of the energy is wasted as heat. All biochemical reactions in the body generate heat as a byproduct. Some people have a higher metabolic rate, because they have a futile cycle. One reaction synthesizes a product, and another reaction breaks it down. And so energy is wasted without accomplishing anything. The wasted energy is released as heat.

Answer 2

The warmblooded species have more mitochondria; in response to low ambient temperature, these mitochondria are used to burn fats and sugars, which in turn release photons of infra-red energy into the body

Answer 3

When you are too cold your body has several ways to heat itself up, one of these is by shivering. When you shiver you muscles are working quickly to try and generate heat. Another way is, when the temperatures are extremely low the blood moves to your body's core, supplying blood to your vital organs. As a reaction to the cold you body curls up/hunches over to try and prevent heat loss. Also, to keep heat loss to a minimum you blood vessels keep away from the top of your skin, this is called vasoconstriction.

Answer 4

Your body tries to cool itself down by sweating and possibly turn red and your heart beats faster.

Answer 5

The body loses excess heat by perspiration or sweating through the epidermis layer (skin).
