Drinking too much water, drinking too much can be dangerous, especially for people with heart disease.
Almost everyone’s heard of the 8×8 rule. Specifically, it states that one needs to drink eight 8-ounce glasses of water every day in order to take in the necessary amount of water to stay healthy. While this advice seems to be universally understood, although almost no one follows it, it’s important to consider where it actually came from and whether or not it’s really accurate.
Who started the 8 x 8 rule?
The 8×8 rule seems to have come from one of two places. A 1945 report published by the National Research Council’s Food and Nutrition Board stated that to stay hydrated, people need to take in one milliliter of water for every calorie they consume. Since the advised daily intake of calories is around 2,000 each day, this would mean the same individual would need to drink 2,000 milliliters of water to match it. This roughly translates to about eight 8-ounce glasses of water. A book written by Dr. Frederick Stare in 1974 also offers the advice that people should take in 6 to 8 glasses of water per day.
However, both of these publications mentioned that water can be found in other places than just its purest, drinkable form. They both mentioned that one can eat fruits and other foods high in water content to get their daily water intake. In addition, they mentioned almost every beverage you can drink—from tea to coffee to soda to beer—contains some form of water.

The best way to gauge how much water you should drink is to pay attention to your body and notice when you feel thirsty.
