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.
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.
