The amount of water you should drink daily can vary based on factors like age, activity level, climate, and overall health, but a common general guideline is:
General Recommendations
-
Women: about 2.7 liters (91 ounces) per day from all beverages and food
-
Men: about 3.7 liters (125 ounces) per day from all beverages and food
About 20% of your daily water intake typically comes from food, so that means:
-
Women should aim for about 9 cups (2.1 liters) of fluids daily
-
Men should aim for about 12.5 cups (3 liters) of fluids daily
Other Helpful Rules of Thumb
-
8x8 Rule: Drink eight 8-ounce glasses of water a day (about 2 liters) – easy to remember, but may be too low for active people.
-
Listen to your body: Thirst is a good signal, and so is the color of your urine (pale yellow = well hydrated).
-
Increase intake if:
-
You’re exercising or sweating a lot
-
You’re in hot or dry climates
-
You’re pregnant or breastfeeding
-
You’re ill or have a fever
