                                According to the U.S. National Academies of Sciences, Engineering, and Medicine, the average healthy adult woman needs about 2.7 liters of total fluid daily, while men need 3.7 liters. This means that for many people, 2l of water a day is not too much, but a perfectly safe and reasonable amount.
