How does the body decrease heat loss?
How does the body decrease heat loss?
Blood vessels supplying blood to the skin can swell or dilate – vasodilation. This causes more heat to be carried by the blood to the skin, where it can be lost to the air. Blood vessels can shrink down again – vasoconstriction. This reduces heat loss through the skin once the body’s temperature has returned to normal.

What are the 4 types of heat loss?
Topic Overview
- Evaporation of water from your skin if it is wet (sweating).
- Radiation (similar to heat leaving a woodstove).
- Conduction (such as heat loss from sleeping on the cold ground).
- Convection (similar to sitting in front of a fan or having the wind blow on you).

Radiation
The correct option is A) Radiation. Radiation is the fastest mode of heat transfer while conduction is the slowest mode of heat transfer.
How is heat gained in the body?
The body can also gain or lose heat through mechanisms of heat exchange. Conduction transfers heat from one object to another through physical contact. Convection transfers heat to air or water. Radiation transfers heat via infrared radiation.
Why do you lose heat from your head?
If you are dressed in warm clothes without a hat on a freezing day, the environment cools the hot blood flowing from your warm body as it passes through the scalp. And this blood then travels back down to the warm body, cooling it as it goes. The second reason involves shivering.
