How much water should you drink a day? It depends on several factors.
Geography, age, environment and habits all contribute to how much water your body uses daily
Are you drinking enough water?
The question seems like it should have a straightforward answer — a specific amount of water you need to drink daily to combat dehydration.
But the rate and way in which the human body takes in and excretes water is not as universal as you might expect. By studying more than 5,000 people living in 23 countries and ranging in age from 8 days to 96 years, researchers have found that the turnover of water in a person’s body varies widely depending on the individual’s physical and environmental factors.
