Questions
How much water should a 180-pound person drink?
A popular rule of thumb is half your body weight in ounces: about 90 oz (2.7 liters, or 11 cups) a day for 180 lbs. Add roughly 12 oz for every 30 minutes of exercise, and more on hot days.
Is "half your body weight in ounces" an official guideline?
No. It is a popular starting point. The U.S. National Academies set an adequate total water intake, from all drinks and food, of about 3.7 liters (125 oz) a day for men and 2.7 liters (91 oz) for women, with roughly 20% usually coming from food.
Does coffee or tea count?
Yes. Most drinks count toward your fluids, including tea and coffee. Water-rich foods like fruit, vegetables and soup count too.
How can I tell if I am drinking enough?
Pale yellow urine and rarely feeling thirsty are good everyday signs. Needs vary with size, activity, climate and health.
