The body loses about 2% of its heat through air conduction. However, water causes more heat loss from the body than air does, so heat can be lost from the body very quickly when it is placed in cold water. Convection (similar to sitting in front of a fan or having the wind blow on you).
What prevents the body from losing too much heat?
Active work contributes to heat loss. To combat this, drink plenty of water and stay well hydrated. Convection – Heat loss by air or water moving across the skin surface. When exposed to cold air, cover exposed skin and take shelter from the wind.

Which parts of the body lose heat most quickly?
The armpits, fingers, and toes also lose heat more quickly than other parts of the body. This is because lots of blood is flowing around these areas and the skin in these parts is thinner which means it's easier for heat to leave the body more rapidly.

What are the 4 types of heat loss?
- 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). ...
