Heat-Related Injury & Illness Prevention
Prevention Techniques
The best defense against heat-related injury and illness is prevention. Staying cool and making changes in your fluid intake, activities, and clothing during hot, humid weather can help the body cope with the heat. Using the cooling center can also prevent heat-related injuries and illnesses.

Remember to practice safety. Don't learn it by accident!

Hyperthermia Causes
Hyperthermia is a term for all heat-related emergencies. These emergencies are brought on by an increase in the body's heat production or by an inability to eliminate the heat produced.

Stages of Hyperthermia
There are three various stages of hyperthermia: heat cramps, heat exhaustion, and heat stroke.

Heat Cramps
Heat cramps are muscle spasms, or cramps, that are thought by some to result from the body losing too much salt during profuse sweating. The cramping is made worse when not enough salt is taken into the body.

Heat Exhaustion
Extreme physical exertion in a hot, humid environment can produce a disturbance of the body’s blood flow, resulting in a mild state of shock. This is brought on by the pooling of blood in the vessels just below the skin, which causes blood to flow away from the major organs of the body. Due to prolonged, profuse sweating, the body loses large quantities of salt and water.

Heat Stroke
If measures are not taken to remove the patient to a cool environment or to stop physical activity and replace lost fluid, conditions can deteriorate.
