Very high body temperatures may damage the brain or other vital
organs. Our bodies are normally cooled by sweating, however, in
some conditions sweating isn’t enough.
Conditions that limit the ability to regulate temperature include
old age, obesity, fever, dehydration, heart disease, poor
circulation, sunburn, and drug and alcohol use.
Summertime activity, whether on the playing field or the
construction site, must be done in a way to aid the body’s
cooling mechanisms and prevent heat-related illness.
