An appropriate daily water intake generally ranges from about 2.7 liters (91 ounces) for women to 3.7 liters (125 ounces) for men, according to the National Academies of Sciences. However, individual needs may vary based on factors such as age, sex, activity level, and climate. Consuming adequate fluids is essential for maintaining hydration, regulating body temperature, and promoting proper function of vital organs.
