What is heat stress?
It’s a signal that the body is having difficulty maintaining it’s temperature range. The heart pumps faster, blood is diverted from internal organs to the skin, breathing rate increases, all in an attempt to transfer more heat to the outside air and cool the skin by evaporation of sweat. If the body can’t keep up then the person suffers from heat cramps to heat exhaustion and finally heat stroke.
Dry Clothes & Skin does not mean you’re not sweating!
In dry climates you might not feel wet or sticky, however you are still sweating. On a very warm day, the body can lose up to two liters of fluid. Be aware of how you are feeling when you start to lose fluids – tired, listless, weak, loss of consciousness, cramps, etc.
