Hot weather
Periods of extremely hot weather -- heat waves -- can cause serious health problems for everyone. In fact, among weather-related events, heat waves are a leading cause of death.
Normally, the body cools itself by sweating. If temperatures and humidity are extremely high, however, sweating is not effective in maintaining the body's normal temperature. When this happens, blood chemistry can change and internal organs -- including the brain and kidneys -_ can be damaged. Heat also can be stressful if the temperature changes suddenly, since it usually takes several days for the body to adjust to heat.
The most common heat-related conditions are heatstroke, heat exhaustion, heat cramps, sunburn and heat rash. Heatstroke and heat exhaustion are the most serious conditions.
