Michelle Obama Thinks You Should Drink One More Glass Of Water A Day

First Lady Michelle Obama launches a new, seemingly innocuous public health campaign encouraging people to drink more water. But some experts say she's over selling the benefits of H20.

CNN's Elizabeth Cohen reports.

In a new announcement, Mrs. Obama talks about her family's habits and says, "The more water we drank, the better we felt"

But some medical professionals say despite her experience, most Americans are sufficiently hydrated and so an extra glass of water isn't going to increase your energy or make you feel better.

Watch the video and decide if you think this argument holds water.
