Water is a fundamental component of all cells in the body. 45 to 65% of total body weight is made up of water. On a regular day, the body loses two to three quarts of water from urinating, eliminating fecal waste, sweating and through water vapor exhaled during respiration. At that rate of loss, it is important to replenish water every day and more important when it is hot outside, while exercising, sweating, when taking medications and during times of stress. Drinking water helps maintain the balance of body fluids. It energizes the muscles, keeps skin supple, assists the kidneys in transporting waste and maintains bowel function. Drinking water is essential to health!
But how much water should we drink? We have all heard that we should drink eight 8 ounce glasses of water a day. But is this fact or fiction? There are no good scientific studies to support the eight by eight rule. The origins of this recommendation date back to 1945. Now, the Institute of Medicine sets general guidelines for total water intake. It recommends that women consume a total of 91 ounces (that’s about 2.7 liters) per day from all food and beverages combined. For men, it’s about 125 ounces a day (or 3.7 liters). Depending on your diet, about 25% of the water you consume comes from your food. See the chart below for water intake recommendations for various stages of life. Then grab a glass. Cheers!
