The amount of water you should drink daily varies by individual factors such as sex, activity level, climate, and health status. General guidelines from reputable sources are:

• For healthy adult men, about 15.5 cups (3.7 liters) of fluids per day is recommended.
• For healthy adult women, about 11.5 cups (2.7 liters) of fluids per day is recommended.

These amounts include all fluids consumed, including water, other beverages, and moisture from food

. Other considerations affecting water needs include:

• Living in hot, humid, or high-altitude environments increases water requirements.
• Higher physical activity levels or exercise increase fluid loss and thus water needs.
• Diets high in salt, sugar, or caffeine may increase water requirements.
• Health conditions like fever, infections, or diabetes can increase water needs.
• Pregnant or breastfeeding women need additional fluids

The traditional "eight 8-ounce glasses" (about 2 liters) rule is a simple guideline but may underestimate needs for many people, especially men and active individuals

. A practical tip is to drink enough water so that your urine is pale yellow, indicating proper hydration

. In summary, aiming for about 3.7 liters (men) or 2.7 liters (women) of total daily fluids, adjusted for personal factors, is a sound approach to staying well hydrated
