The body can live for several weeks without food, but would die after a few days without water. About 64 to 80 ounces of water a day is lost through perspiration, urine, bowel movements, and normal exhalation. Water is lost more rapidly during exercise, in a dry climate, at a high altitude, when lots of caffeine or alcohol are consumed, when a meal is skipped, or when ill. To assure adequate water intake, drink enough to prevent the urine from being dark in color. Early symptoms of dehydration are fatigue, weakness, lethargy, dizziness, and headache.
