22 Heat
What Is Heat Stress?
It's a signal that says the body is having difficulty maintaining its narrow temperature range. The heart pumps faster, blood is diverted from internal organs to
the skin, breathing rate increases, sweating 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 effects ranging from heat cramps to heat exhaustion, and finally to heat stroke.
