Drinking 8 Glasses of Water a Day Is a Myth, According to Study

Sacha Strebe

We are told time and time again to keep up our water intake, and to ensure we get the recommended eight glasses of water a day. But according to Aaron E. Carroll, professor of pediatrics at Indiana University School of Medicine, it's just not true because "there is no science behind it." Wait, what? Say it ain't so. 

In an article for The New York Times, Carroll details his attempts at trying to convince us. In 2007, he co-authored a paper on medical myths that explained why eight 8-ounce glasses of water a day isn't necessary. He said this "paper got more media attention (even in The Times) than pretty much any other research I’ve ever done." But apparently it didn't make any difference. Not even his published book on medical myths could make us change our water-drinking habits.

So where did the myth originate, then? And why do we still believe eight glasses is the minimum daily water requirement? Aaron explains: "Many people believe that the source of this myth was a 1945 Food and Nutrition Board recommendation that said people need about 2.5 liters of water a day. But they ignored the sentence that followed closely behind. It read, “Most of this quantity is contained in prepared foods.” Carroll says water is in pretty much everything we consume, from fruits and vegetables to juice, beer... even tea and coffee. Yes, that's right, coffee. That's another myth the professer debunks. If you think it's going to dehydrate you, "research shows that’s not true, either."
