How Many Oz of Water Should I Drink Daily?

Hydration is important to health.

Recommended Daily Water Intake

The National Institutes of Health recommends that adult men drink 13 cups, or 104 ounces, of water daily, with women advised to drink 9 cups, or 72 ounces. If you are feeling thirsty, chances are high you are beginning to become dehydrated already and should definitely reach for a drink. Some of your necessary water intake can come from other beverages, but avoid excessive caffeine.

Special Cases

Pregnant and nursing women are advised to drink more water than average women. If you are going to be doing some heavy exercising, you need to replace the additional water that will be lost from sweating. Similarly, in very hot times of the year, your body loses more water. Modify your water intake accordingly.

Bottom Line

Lots of us don't drink as much water as experts from the Mayo Clinic and the National Institutes of Health recommend. The common "8 ounces, eight times per day" is enough water to keep you going. To maintain the best health, however, consider increased water drinking as a part of your daily routine.
