There has never been a conclusive study on exactly how much water you should drink everyday! But Doctors generally agree that you should think of 8 glasses of water a day as the bare minimum, and then keep sipping.
It’s just that there are circumstances in which water needs increase, healthy men and women generally need to consume water in such large quantities.
