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.

BOB DOUGHTY: Experts say water is important for many reasons. Between fifty-five and seventy-five percent of the body is water. Water in blood carries hormones and antibodies through 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.
Health experts say adults should drink about two liters of water a day to replace all the water lost in liquid wastes and perspiration. They say people should drink more than that in hot weather.
Experts say it is important to drink before, during and after exercise. They say we should drink water even before we start to feel like we need something to drink. During hot weather, cool liquids are best. Also, avoid sweet drinks and alcohol.
FAITH LAPIDUS: We need to add that doctors also say it is possible to drink too much water. Some people, for example, do this if they exercise hard during a heat wave. Experts with the Mayo Clinic say drinking too much water can cause hyponatremia. In this condition, the level of sodium in the blood falls too low.
The result is that the amount of water in the body increases. This causes cells to become larger. Mayo Clinic experts say the enlarged cells can cause a person to become sick or restless. They also can interfere with mental ability, make muscles weak and cause pain in the head. In a mild case, simply reducing fluids may be all that the person needs. But medical help is necessary if the condition is more severe.
