So how much water does the average, healthy adult living in a temperate climate need? In general, doctors recommend 8 or 9 cups. Here are the most common ways of calculating that amount:
Replacement approach. The average urine output for adults is about 1.5 liters (6.3 cups) a day. You lose close to an additional liter (about 4 cups) of water a day through breathing, sweating and bowel movements. Food usually accounts for 20 percent of your total fluid intake, so if you consume 2 liters of water or other beverages a day (a little more than 8 cups) along with your normal diet, you will typically replace your lost fluids.
Eight 8-ounce glasses of water a day. Another approach to water intake is the "8 x 8 rule" drink eight 8-ounce glasses of water a day (about 1.9 liters ...more
Until recently, about the only definitive research regarding fluid intake and health was a study of Seventh Day Adventists that was published in 2002. Researchers at Loma Linda University in California reported that people who drank at least 5 glasses of water per day had a lower risk of a heart attack during the 6-year period than people who drank 2 or fewer glasses per day (Chan J, et al. 2002).
But even this information is not very precise: how much water is "5 glasses" anyway? To establish better guidelines on fluid intake, a panel of experts from the US and Canada was convened on behalf of the Institute of Medicine. Their report was made public in February 2004
