What is the 8x8 drinking water rule?

The 8x8 drinking water rule is a popular guideline that suggests you should drink eight 8-ounce glasses of water a day, which equals about 64 ounces or roughly 1.9 liters.

Here's a quick breakdown:

• 8 glasses

• 8 ounces per glass

• Total = 64 ounces (1.9 liters)

But is it scientifically accurate?

Not exactly. While it’s a simple and easy-to-remember rule, hydration needs can vary widely depending on:

• Body size and weight

• Activity level

• Climate and temperature

• Diet (e.g., eating water-rich foods)

• Health conditions

What do experts recommend?

Health authorities like the U.S. National Academies of Sciences suggest a more individualized approach:

• About 3.7 liters (125 oz) per day for men

• About 2.7 liters (91 oz) per day for women
  

  These totals include all fluids — not just plain water — and water from food.
