It's a myth.

And that link has made drinking 8 glasses of water per day, or more, to stay healthy, lose weight, and avoid dehydration, a myth? Perhaps you should read it again....

75% of Americans are chronically dehydrated.

Because they don't drink enough water....8 glasses would be perfect....considering your urine becomes clear around 8-10 glasses, which would be a very viable sign that you are properly hydrated. Its not a myth.
