    How sleep transformed professional football

 

    A few decades ago, professional footballers spent their nights partying. Now, they are much more aware of the benefits of a good night’s sleep.

    The change began in the mid-1990s, when mattress salesman Nick Littlehales contacted the manager of the Manchester United football team, Alex Ferguson, asking whether he had ever considered how sleep affected performance on the pitch. Interested, Ferguson arranged for Littlehales to give a presentation to his team.

    Gradually, club managers began to pay more attention to scientific sleep research, and for good reason. (...)

    Now, many teams and players are making an effort to improve their sleep patterns, using various means. James Milner from Manchester City found it hard to sleep after evening games, so would play computer games into the early hours. As a result, he was too tired to train the following morning. Since these interventions are cheap and effective, even the less well-known teams can benefit. (...)

    Whereas in the past, playing after a party and a few hours’ sleep was seen as a badge of honour, a good sleep is now considered an essential part of performance.
