Kidney experts looking into the alleged health benefits of drinking lots of water have found the evidence to be far from watertight, Reuters reports. Claims that increased water intake improves skin tone, flushes toxins from the body, reduces appetite, and prevents headaches have little solid research behind them, according to a study to be published in the Journal of American Phrenology.
"Our bottom line was that there was no real science behind these claims and that they probably represent folklore," a researcher said. The findings pour cold water on claims that eight glasses a day boosts health, but the doctors emphasized they also found no reasons not to drink water. "Drink when you're thirsty," one said. "That's the way your body is designed."
