how much water are you supposed to drink a day

The recommended daily water intake varies based on factors like age, sex, activity level, and climate. Generally, healthy adult men should aim for about 13 cups (104 ounces or approximately 3.7 liters) of fluids daily, and healthy adult women should aim for about 9 cups (72 ounces or approximately 2.7 liters) of fluids daily. These amounts include all fluids consumed, not just water. Pregnant women are advised to consume about 10 cups (80 ounces), and breastfeeding women about 13 cups (104 ounces). Children have lower recommended amounts based on age, for example, 5 cups (40 ounces) for 4-8 years old and 8-11 cups (64-88 ounces) for 14-18 years old. Factors such as physical activity, hot climates, diet, and health conditions can increase individual water needs. The familiar “8 glasses a day” rule is a simplified guideline but may not fit everyone's needs precisely.
