What is the relationship between temperature and heat loss in the human body?

The human body loses heat through several mechanisms, including conduction, convection, radiation, and evaporation.
The contribution of the human body's temperature to the total heat decreases in dry air, but increases when submerged in water.
When the temperature of the air or water is higher than the body's temperature, the body increases its temperature through conduction and convection.
In resting conditions, radiation is the main method of heat loss from the body.
