Clinical hydration guidelines

Clinical hydration guidelines recommend that adults generally drink about 8 cups (about 2 liters) of water daily, but this varies based on individual needs, activity levels, and climate. Proper hydration helps maintain body functions like temperature regulation, digestion, and joint lubrication. To stay well-hydrated, listen to your body’s signals—drink when you're thirsty—and monitor urine color; pale urine usually indicates good hydration. In clinical settings, hydration may be adjusted for specific health conditions, activity levels, or during illness, to prevent dehydration or overhydration.
