The human body requires approximately _________ of fluid each day.

• A. 3 liters
• B. 2 liters
• C. 4 liters
• D. 1 liter

Answer: (B)

Maintaining hydration comes from balancing what you drink with what you lose daily. The body loses water mainly through urine, sweat, breathing, and a bit through feces, so your intake should roughly replace those losses. For a typical adult, about two liters of fluid per day is a common guideline. This total includes fluids from beverages as well as the water content in foods. Real-world needs vary with climate, activity, health, and age: hot or humid conditions and exercise increase losses and raise needs, while sedentary, cooler conditions can lower them. So two liters serves as a solid baseline for everyday hydration.
