Normally average people can stay fine drinking 2 liter of water daily.Because almost that much water our body drains a day. But you have to drink much more than that if you do hard works because a hard working person drains more than that. At the end of the day, no one can tell you exactly how much water you need. This depends on the individual.

What if you drink too much water.

Some people think drinking too much water is also good. But it is not. Overhydration is an imbalance of fluids. It happens when your body takes in or holds on to more fluid than your kidneys can remove. Drinking too much water or not having a way to remove it can cause water levels to build up. This dilutes important substances in your blood. And most importantly it will make you go to toilet more and more and more. So just trust your thirst. Drink water when you feel the need of it.
