In other words, what’s the average daily water requirement for the average adult?
Since this question is so controversial, let’s quote directly from a well-regarded academic textbook. (The abbreviation ca. means circa, academic speak for “approximately.”) Hold on to your toilet seat:
A person weighing 70 kg [155 lbs] requires at least ca. 1,750 ml [59 oz] water per day. Of this amount ca. 650 ml is obtained by drinking, ca. 750 ml is the water contained in solid food, and ca. 350 ml is oxidation water. If more than this amount is consumed by a healthy person it is excreted by the kidneys, but in people with heart and kidney disease it may be retained (edema; pp 505, 771f).

650 ml water is dus maar nodig om te drinken per dag (2,5 glas) in plaats van de vaak genoemde 8 glazen water per dag. Lees hier verder wat de consequenties kunnen zijn als je teveel water drinkt:
