About heat illness

How does heat illness happen?

Heat illness risk is affected by the following variables including the environmental condition, body, and activity.
The relevant environmental conditions are high temperature, high humidity and a lack of wind.
Lack of heat acclimatization and metabolic heat production from overexertion or exercise are risk factors associated with the body and activity.
These variables may cause heat illness.

The body normally cools itself via evaporative and radiative heat loss to the environment by sweating and increasing the skin temperature.
