The general recommendation for daily water intake for healthy adults is about 13 cups (104 ounces or approximately 3.7 liters) for men and about 9 cups (72 ounces or approximately 2.7 liters) for women. These amounts include all fluids consumed throughout the day, including water, other beverages, and water content in foods. The exact amount needed can vary depending on factors such as physical activity, climate, age, health, and pregnancy or breastfeeding status. For example, pregnant women may need around 10 cups (80 ounces) daily, and breastfeeding women may need up to 13 cups (104 ounces). This guidance reflects fluid intake recommendations from the National Academy of Medicine and similar health authorities.
