What is the recommended daily water intake listed?

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

Answer: (A)

Hydration supports maintaining blood volume, regulating body temperature, and removing wastes, so a daily baseline for fluids is a practical target. For most adults, about two liters of water per day (roughly eight cups) is the standard amount suggested in many SEHS materials. This baseline helps cover fluid losses through urine, breathing, and skin under typical conditions, while allowing for variations due to climate, activity level, and individual needs. One liter is generally too low to meet daily needs for most people, four liters is more than the typical baseline and can be excessive for many, and three liters can be appropriate only for higher demands in some individuals. Thus, two liters is the commonly listed daily recommendation.
