Tag: Hydration by age

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.
