Other myths about water include the idea that lots of water equals healthier skin. Since the body is already 60-70 per cent water, a few extra glasses each day has a limited effect, according to Dr. Stanley Goldfarb, a kidney expert at the University of Pennsylvania.

Madeline Fernstrom of the University of Pittsburgh also said that drinking water is a helpful tool for dieters but doesn’t necessarily lead to weight loss. Consuming foods with high water content-like watermelon, lettuce or grapefruit- results in more weight loss than swapping them for more glasses of water.

Scientist have also busted the myths that drinking lots of water helps clear out toxins and the idea that if you’re thirsty, you’re already dehydrated.

Drinking too much water can actually be dangerous by causing low blood sodium levels and exposing people to pollutants in the water, according to Margaret McCartney, a general practitioner.

The reports aren’t saying you should simply stop drinking water but you no longer have to count out your daily water intake, simply drink when you’re thirsty and you should be fine.
