I am an exercise physiologist, and my research focuses on overhydration and how drinking too much water affects the body.
How much water each person needs to drink mainly depends on three factors:
This is why when we drink more water than our body needs -- above thirst -- we immediately have to pee out any excess water.
Data suggests that drinking about two liters of water per day reduces kidney stone formation in people with a history of kidney stones and decreases the number of bladder infections in people with a history of bladder infections.
Drinking extra water alone does not help kids lose weight unless water intake replaces the ingestion of higher-caloric beverages, such as soda, or makes people feel "full" before meals.
Drinking water can affect some people's mental state.
So, do you need to drink eight glasses of water per day?
