Drink 8 glasses of water each day! Everyone knows that now - it is conventional wisdom. Apparently for most of us it really is not that necessary. Is Drinking Lots Of Water All Wet? The comments come from a very well respected researcher.

The journal asked him to review all the scientific studies he could find and he concluded that someone misinformed has been telling people to drink large amounts of water when most do not need to.

“I am referring to healthy adults in a temperate climate leading a largely sedentary existence,” Valtin said. “Persons with certain diseases must have large volumes of water — kidney stones are probably the most common example.”

The rest can just drink enough to slake thirst — and this includes coffee, tea, and even beer — despite their diuretic effects, Valtin said.

He hopes people will be relieved of the guilt of not getting enough water, and of the expense of buying bottled water to drink throughout the day.

“There is also the possibility that if you drink a lot of water that happens to be polluted then of course you get more pollutants,” Valtin said.

“Then there is the inconvenience of constant urination, the embarrassment of having to go to the bathroom all the time,” he added.
