What is the recommended daily water intake for men?

• A. 2.0 L (68 oz) per day
• B. 3.0 L (102 oz) per day
• C. 3.5 L (118 oz) per day
• D. 3.7 L (125 oz) per day

Answer: (D)

Staying adequately hydrated means aiming for the total daily water intake recommended for adults. For men, that total is about 3.7 liters (roughly 125 ounces) each day from all beverages and moisture in food. This amount helps replace water lost through breathing, urination, sweating, and bowel movements, and it takes into account body size and typical activity. If you’re exercising, in hot weather, or sweat more, you may need more than this baseline. The other options fall short of the established guideline: 2.0 L is far below the recommendation, and 3.0 L or 3.5 L do not meet the 3.7 L target.
