If vigorous exercise makes you a better sleeper, can more and better sleep make you a better athlete? According to Haley A. Davis and James B. Maas...

As a sleep researcher who focuses on how sleep affects elite athlete, I have studied the effects of travel and disrupted sleep on athletes for many years. The combination of cross-country travel and athletic performance is not pretty. Travel and circadian timing matter.

Athletes at all levels of play have access to a powerful tool to improve their performance, one that won't break any laws or put anyone's health at risk. What's this wonder drug? Sleep.

I think the sleep revolution is one major endorsement away from exploding into popular culture. The foundation is in place. We just need one athlete to speak out about how he or she considers sleep to be a cornerstone for success.

In a new Stanford University study, athlete subjects improved their performance, and their overall sense of physical and mental well-being, when they eliminated sleep deficiencies from their routine.

What's the difference between the best athletes in the world and the next best? Fame, glory, fortune -- and inches, millimeters and milliseconds.
