Chris Winter

William Christopher Winter is an American sleep researcher, neurologist, author, and authority regarding sleep and athletic performance. A 2010 article in Trail Runner Magazine described Winter as "the leading expert in the field of sleep disruption, in athletes and issues related to travel." He is credited with coining the term circadian advantage after studying the effects of travel on Major League Baseball teams. He studied the effect of sleep timing preference on Major League Baseball pitcher performance, and hitting performance. In 2013, his research linked the sleepiness of Major League Baseball players to a reduced career longevity. This work led to research into sleepiness as a predictor of NFL Draft value in which the sleep of 560 Atlantic Coast Conference (ACC) football players and their eventual draft success was studied.
