Heat Stroke Risks. With summer here and the temperatures rising, it is important to understand the health risks that excessive heat can bring and know the signs of heat-related illnesses.

Older adults and people with chronic medical conditions are particularly susceptible to hyperthermia and other heat-related illnesses. The National Institute on Aging (NIA), part of the National Institutes of Health, offers advice to help combat the dangers of hot weather.

Heat stress, heat fatigue, heat syncope (sudden dizziness after exercising in the heat), heat cramps and heat exhaustion are all forms of hyperthermia. Hyperthermia is caused by a failure of the body’s heat-regulating mechanisms. The risk of hyperthermia can increase with the combination of higher temperatures, underlying general health, and individual lifestyle.
