Too much heat can be harmful to your health. It can lead to weakness, disorientation, exhaustion, and in severe cases, it can lead to heat stroke. To learn more about heat-related illnesses, see HealthLinkBC File #35 Heat-related Illness.
Make good clothing choices in hot environments to help prevent heat-related illnesses. Clothing should be light-coloured, lightweight and draw sweat from the skin. The evaporation of sweat will decrease the body's temperature.
The upper body sweats more than the lower half, so wearing clothing that is loose-fitting and allows for more air circulation from the waist up is a good way to transfer heat away from the body.
We lose 50% of our body heat from our scalp and our face. Wide brimmed hats used for sun protection should be designed to allow for good ventilation of the body's heat from the head.
