According to the U.S. National Academies of Sciences, Engineering, and Medicine, the average daily fluid intake for men is about 15.5 cups and for women about 11.5 cups. But this varies, and understanding how many glasses of water should you drink a day by age is key to optimal health.

Water is your body's principal chemical component, constituting 50% to 70% of your body weight, with every cell, tissue, and organ depending on it to function properly. However, daily hydration needs are not one-size-fits-all, as they change significantly throughout a person's life.

Mature human milk is composed of approximately 87% water, making it a highly effective and water-based fluid for infant nutrition. This remarkable composition ensures that babies receive all the necessary hydration without needing additional water, even in hot climates, as recommended by health organizations like the World Health Organization (WHO).

Mature human breast milk is approximately 87% water, making it the most abundant component. This high water content ensures that breastfeeding infants receive optimal hydration, even in hot weather, without needing additional fluids.

According to the National Academies of Sciences, Engineering, and Medicine, daily fluid intake recommendations vary widely by age, gender, and other factors, affirming that the question 'Does water intake depend on age?' has a definitive 'yes' as its answer. While the average adult needs about 11.5 to 15.5 cups of fluid daily, an infant's requirements are vastly different, highlighting how hydration needs change throughout the lifespan. This guide will explain why this is the case and what you should know for each life stage.
