Water fiction

In another example of science meets received wisdom, the New York Times is reporting no basis for the belief that drinking 8 glasses of water a day is good for you. For that matter, the scientists could find little evidence to support the belief that drinking "extra water" is of benefit to pretty much anyone.

Numerous claims have been made about water — that it prevents headaches, removes dangerous “poisons,” improves the function of various organs and is associated with reduced risk for various diseases. But none of these is supported by scientific evidence. The authors were not even able to find a study leading to the “eight glasses a day” rule, whose origin remains unknown.
