Heatstroke, also known as sunstroke or hyperthermia, occurs when normal mechanism's for cooling the body off are insufficient to keep the body at a safe temperature. It can be caused by prolonged exposure to high temperatures, inadequate fluid intake, or an impaired ability to sweet. The young, elderly, and chronically ill are more prone to develop hyperthermia, but anyone can develop heatstroke.

Heatstroke is a medical emergency. Heatstroke, or hyperthermia, is the most severe form of heat related illness that can lead to organ failure if emergency medical treatment is not received quickly. Heat stroke can be prevented by staying hydrated, staying indoors, and minimizing outdoor activity on hot days.

Staying well hydrated can help to prevent heatstroke.

1. Don’t wait until you are thirsty to drink. You should be drinking more fluids when it's hot out than you normally consume.
2. Avoid alcoholic beverages and drinks with lots of sugar. These drinks can have a diuretic effect, causing your body to lose fluid.
3. Very cold drinks can produce cramping.

People who are more susceptible to heatstroke, such as infants, the elderly, and those with chronic illnesses should stay indoors on very hot days.

1. An air conditioned location is best; fans will not prevent heat related illness when the temperature is above 90 degrees.http://www.bt.cdc.gov/disasters/extremeheat/heattips.asp
2. If you don't have air conditioning at home, considering visiting the public library or a shopping mall.
3. Cool baths and showers can help reduce body temperature as well.

Avoid strenuous activity outdoors in high temperatures. If you must participate in a physically demanding activity, follow these tips to minimize the risk of heatstroke:

1. Try to exercise early in the morning or later in the evening, when temperatures are lower.
2. Take frequent breaks.
3. Drink 16-32 ounces of water per hour.
4. Wear a wide brimmed hat.
