Drinking water is important, and many people do not drink the recommended 2L per day. Why, then, do we have to constantly remind ourselves to drink enough to meet those requirements?

Answer 1

We don’t need to constantly remind ourselves to drink enough. Most people will get the 2L of water a day without problems. Keep in mind that you don’t need to drink 2L a day, there is a lot of water if your food and thirst exist, it’s just that we usually get the water we need before we feel the thirst.
