Heat illness or heat-related illness is a spectrum of disorders due to environmental exposure to heat. It includes minor conditions such as heat cramps, heat syncope, and heat exhaustion as well as the more severe condition known as heat stroke.

Classification

A number of heat illnesses exist including:

• Heat stroke - Defined by a body temperature of greater than 40 °C (104 °F) due to environmental heat exposure with lack of thermoregulation. Symptoms include dry skin, rapid, strong pulse and dizziness.
• Heat exhaustion - Can be a precursor of heatstroke; the symptoms include heavy sweating, rapid breathing and a fast, weak pulse.
• Heat syncope - Fainting or dizziness as a result of overheating.
• Heat edema
• Heat cramps - Muscle pains that happen during heavy exercise in hot weather.
• Heat rash - Skin irritation from excessive sweating.
• Heat tetany - Usually results from short periods of stress in intense heat. Symptoms may include hyperventilation, respiratory problems, numbness or tingling, or muscle spasms.

Prevention

Prevention includes avoiding medications that can increase the risk of heat illness (e.g. antihypertensives, diuretics, and anticholinergics), gradual adjustment to heat, and sufficient fluids and electrolytes.

Treatment

Mild disease can be treated with fluids by mouth. In more significant disease spraying with mist and using a fan is useful. For those with severe disease putting them in lukewarm water is recommended if possible with transport to a hospital.

Epidemiology

Heat stroke is relatively common in sports and is the cause of about 2 percent of deaths. Football in the United States has the highest rates.

Between 1999 and 2003, the US had a total of 3442 deaths from heat illness. Those who work outdoors are at particular risk for heat illness, though those who work in poorly-cooled spaces indoors are also at risk. Between 1992 and 2006, 423 workers died from heat illness in the US.

History

Heat illness used to be blamed on a tropical fever named calenture.

The changes due to time-related ageing, thinner, withered skin are similar to those caused by the menopause, which also induces some signs of hyperandrogeny. Sun-related changes, which occur mainly on uncovered areas, vary so widely that some authorities prefer the terms "dermato-heliosis" or "helio-dermatitis" to that of solar ageing. Solar elastosis is the most typical change and is visible on the face as a yellowish skin criss-crossed by deep wrinkles. On the neck and extended surfaces of the limbs, the skin is atrophied and often dyschromic. Excessive exposure to the sun is also responsible for most skin cancers, which are known to occur mainly on exposed parts.
