Research debunks health value of guzzling water: "The notion that guzzling glasses of water to flood yourself with good health is all wet, researchers said on Wednesday.Dr. Stanley Goldfarb and Dr. Dan Negoianu of the University of Pennsylvania in Philadelphia reviewed the scientific literature on the health effects of drinking lots of water.People in hot, dry climates and athletes have an increased need for water, and people with certain diseases do better with increased fluid intake, they found. But for average healthy people, more water does not seem to mean better health"
"Our bottom line was that there was no real good science -- or much science at all -- behind these claims, that they represent probably folklore"
