Heat exhaustion can lead to heat stroke if it is not treated. Heat stroke is the most serious disorder linked to hot weather. It results when the body is not able to control its temperature. The body temperature increases and perspiration fails.
Generally, the body temperature rises to more than 40 degrees Celsius. The body stops perspiring. The skin becomes dry and very hot. A person may become unconscious, not knowing what is happening.
Doctors say tissues and organs begin to cook when the body's temperature is higher than 42 degrees Celsius. Permanent brain damage and death may result. Someone suffering heat stroke requires immediate medical attention. Doctors say such treatment is necessary or the person could die before help arrives.
The purpose of immediate treatment is to cool the victim as quickly as possible to stop the temperature from increasing. Begin by moving the victim out of the sun. Raise the person’s feet up about thirty centimeters. Take off the victim’s clothing. Put cool water on the body. Place pieces of ice in areas where blood passageways are close to the skin. These include the back of the neck and under the arms.
Experts say it is important to know the danger signs of the medical disorders linked to hot weather. It is also important to know what to do if the signs appear in yourself or in someone else.
Experts say water is important for many reasons. Between 55 and 75 percent of the body is water. Water in blood carries hormones and antibodies throughout the body. Water in urine carries away waste materials. Water is needed for cooling the body on hot days, and when we are working or exercising. Water carries body heat to the surface of the skin. There, the heat is lost through perspiration.
