how many glass of water you should drink a day
The old adage of 8 glasses a day is no longer true. Instead, think about how much you weigh and divide that number in half. That's how many ounces of water you should drink per day. For instance, a person who is 200 pounds, should drink 100 oz. of water per day to be adequately hydrated. (That's 12.5 glasses of water!) An athlete with a high level of muscle mass should drink even more, about two-thirds of their body weight in ounces per day.
