Prevention of Dehydration
Prevention of dehydration is better than cure. Adults should drink at least 6 glasses of fluids daily (including fluid from eating foods high in water content, such as fruits and vegetables). Fluid intake should be increased on hot days, when working or exercising in hot weather, during or after prolonged exercise, and, if possible, when people have vomiting and/or diarrhea. Exercise, a high body temperature, and hot weather increase the body’s need for water. Flavored sports drinks have been formulated to replace electrolytes lost during vigorous exercise. These drinks can be used to prevent dehydration. People should drink fluids with electrolytes before and during vigorous exercise as well as afterward. Before exercising, people with heart or kidney disorders should consult their doctors about how to safely replace fluids. People should make sure that older family members have access to plenty of water when they are alone in a hot building or place.
