Not getting 8 glasses of water? It's ok

We've all heard we're supposed to drink eight glasses of water a day to stay healthy, but new research suggests that may be just a myth.

Kim White never exercises without a bottle of water on hand.

Reporter asks: "How much water do you think you're supposed to drink a day?"

"According to my trainer, about, I think, eight 16-ounce glasses," she responds.

But that's too much according to new research that suggests drinking glass after glass of water to stay healthy is just unnecessary.

Nephrologist Dr. Stanley Goldfarb says, "Avoiding certain foods, not smoking, getting your exercise, those are the things that benefit your health. And water drinking really doesn't.

The findings from the journal of the American Society of Nephrology finds that too much water hinders your kidneys ability to excrete. The body loses a quart to quart and a half of water each day, and, doctors say, drinking enough water to replace that wouldn't hurt.

So, what it comes down to is how much water works for you. People we talked with definitely know what their needs are.

Charles Bennett says he feels great and only drinks when he is thirsty. "I've been on the water craze for a while and found it was restricting my movements too much."

About 60 percent of his body's weight is already water, and, doctors agree, when exercising in hot climates, we need to drink more to stay hydrated.

Overall, there isn't any evidence out there proving real water is better for us.
