Drinking too much water can damage the kidney - Strange but True

According to a new scientific review published in the Journal of the American
Society of Nephrology
, drinking too much water can actually damage the
kidneys.

Liquid H2O is the sine qua non of life. Making up about 66 percent of the human body, water runs through the blood, inhabits the cells, and lurks in the spaces between. At every moment water escapes the body through sweat, urination, defecation or exhaled breath, among other routes. Replacing these lost stores is essential but re-hydration can be overdone. There is such a thing as a fatal water overdose.

a 28-year-old California woman died after competing in a radio station's on-air water-drinking contest. After downing some six liters of water in three hours in the "Hold Your Wee for a Wii" (Nintendo game console) contest, Jennifer Strange vomited, went home with a splitting headache, and died from so-called water intoxication.

Scientists say there is no proof for the urban myth that it is beneficial for the average healthy individual to drink a lot of water.

There is a long-held idea that drinking a lot of water helps clear the body of toxins, keep organs in tip-top shape and even helps keep weight off and improve skin tone, but scientists are skeptical.

As a kidney specialist, Dr. Stanley Goldfarb of the University of Pennsylvania is interested in how the kidney handles fluids, which prompted him and a colleague, Dr. Dan Negoianu, to review the scientific literature on the benefits of drinking water. In doing so, the researchers debunked four myths.

Research results suggest that contrary to popular belief, drinking a lot of water does not suppress appetite, flush toxins from the body, reduce headaches or improve the skin.

There are circumstances under which drinking a lot of water may even be unhealthy: "In long-distance runners, for example, more harm is done by over-drinking during races than by long distance runners who under-drink"

So friends, idea that drinking eight glasses of water a day is good for your health has been dismissed now
