The First Lady is encouraging Americans to drink water as part of her Drink Up campaign, but some in the medical community are pushing back against the idea of uniform hydration advice. Douglas J. Casa, chief operating officer of The Korey Stringer Institute, and a professor of kinesiology at the Neag School of Education at University of Connecticut, explains what is known about how much water is the right amount to drink and what listeners can do to stay hydrated.

Peter Moore, editor of Men's Health magazine, and Douglas Casa, director of Athletic Training Education at the University of Conneticut, discusses what to watch out for when exercising in extreme heat following the collapse of a racer in yesterday's New York City Triathlon.
