How much water is commonly recommended per day?

• A. 32 ounces
• B. 64 ounces
• C. 96 ounces
• D. 128 ounces

Answer: (B)

Staying hydrated supports nearly every body function, from energy levels to digestion and kidney function. A practical baseline many health guidelines teach is eight cups of water per day, roughly two liters. This amount is easy to remember and works for many healthy adults, with water from foods and other beverages counting toward the total. Individual needs vary with climate, activity, health, and body size, so you might drink more in hot weather or during exercise and less if you’re very inactive. The smaller amount would often be insufficient for most people, while the larger amounts are not typically necessary unless there are special circumstances.
