8x8 Benefits Don't Hold Water

During your annual physical, your doctor most likely asked a number of routine health questions. The amount of water that you drink on a daily basis was likely among them. For years, it's been recommended that we drink a quantity known as 8x8 (eight glasses of eight ounces) each day. While it's true that athletes and people who live in hot, dry climates require more fluids than the average Jane or Joe, there's no reason to believe that healthy normal people need to down 64 ounces of water a day. That's what scientists at the University of Pennsylvania reported in the Journal of the American Society of Nephrology.

The Bigger Picture: Their study found no scientific evidence suggesting that water clears bodily toxins, enhances organ function or improves skin tone. On the other hand, there's no evidence that drinking 8x8 glasses of water a day will do you any harm either. Of course, not getting enough fluids is another issue entirely especially for hard-training athletes. Inadequate hydration can adversely affect performance along with overall health. This fact has been very well documented in an extensive body of research.
