Sleepy athletes

Professional athletes who don’t get enough sleep could be cutting their careers short.

A study finds National Football League players who are sleepier in the daytime have only a 38% chance of staying with the team, compared to 56% of non-sleepy players.

In Major League Baseball, the level of play declines much faster for players who are sleepy during the day.

Researchers say using a questionnaire known as the “Epworth Sleepiness Scale” could help teams decide who will be their most productive players.
