A Kneeling Oblique Crunch How Many Bottles of Water Should You Drink in a Day?

Replacement Approach

One option for making sure you get enough fluids is to attempt to replace the fluids naturally lost through everyday activities and bodily functions. The average fluid lost for adults is around 10 cups per day.

Since food intake typically makes up about 20 percent of your daily fluid intake, a simple eight cups of water or other fluid will insure that you replace daily lost fluids.

8-by-8 Rule

It has been largely suggested (though lacking in hard scientific research) that the "8-by-8 rule," or drinking eight 8-ounce glasses of water each day will provide ample fluid intake.


If you rarely feel thirsty and your urine output isn't unusually low or high, your daily fluid intake is probably adequate. You always have the option of contacting your physician if you're concerned about the amount of water/fluid that you are consuming on a daily basis.
