How Many Water Bottles Should I Drink A Day?

If you are physically active, in hot climates, pregnant, or breastfeeding, your fluid needs increase, sometimes up to about 13 cups or more. The familiar advice of "8 glasses a day" (each glass 8 ounces) is a reasonable goal but can vary depending on individual factors such as body size, exercise, and health conditions.

A simple personalized guideline is to drink half your body weight in ounces of water daily—for example, a 150-pound person would drink about 75 ounces. Always listen to your thirst and adjust intake for sweat loss or illness.
