Myth or Truth: I need 8 glasses of water a day. Myth. The Institute of Medicine says adult men actually need about 13 cups (3 liters) per day of fluid; adult women need about 9 cups (2.2 liters) of fluid. (You get about an additional 2 1/2 cups of fluid from foods.).
Do you drink 8 glasses of water or other drinks a day? This is how much some experts say that adults need each day. Small kids need less water than this â 6 or 8 smaller drinks would be good. At least make sure that you drink water in the morning, at recess time, lunch, after you are running around and in the evening.
