Are 2 liters enough water for the day?

Answer 1

The actual amount varies by climate, lifestyle, body mass and activity, health, and other factors - but the Institute of Medicine guide indicates an average adult woman should drink about 2.2 liters per day, and man about 3 liters. The old advice to drink 8 x 8-ounce glasses of water per day isn't too bad.

It's possible to survive on less - but with no water intake a human will dehydrate and die in about 3-6 days.

Answer 2

That's the minimum, I have taken to drinking about three a day though

Answer 3

Because if you don't your body will get dehydrated
