Most people lose over 16 ounces (or 500 milliliters) of water per day through urine. That means drinking at least 16 ounces (2 cups) of fluids can help replace lost urine. If your urine is very light in color and has very little odor, it indicates that you are well hydrated. Dark urine may indicate dehydration.

Your body needs different amounts of water, depending on how much you exercise, how much you urinate, and how much you sweat. For most healthy adults, the amount of water to prevent dehydration is:
