The amount of water you should drink per day depends on various factors such as your sex, age, activity level, climate, and overall health. General recommendations are as follows:

• For men, about 15.5 cups (3.7 liters) of fluids daily is advised.
• For women, about 11.5 cups (2.7 liters) of fluids daily is recommended

These amounts include all fluids consumed, not just plain water, as beverages like tea, coffee, and water-rich foods also contribute to hydration

. Other guidelines suggest aiming for 6 to 8 cups of fluid per day, but this can vary widely based on individual needs

. Factors that may increase your water needs include:

• Physical activity: More water is needed to replace fluids lost through sweat.
• Hot or humid weather: You may feel thirstier and require more fluids.
• Health conditions or medications that affect hydration

It is possible to drink too much water, which can overwhelm the kidneys and cause a dangerous condition called water intoxication, but this usually requires consuming excessive amounts (e.g., 8 to 10 liters in a short time)

. In summary, a good general target is around 3.7 liters (about 13 cups) for men and 2.7 liters (about 9 cups) for women daily from all fluids combined, adjusting for personal factors and thirst cues
