Snoozers Are, in Fact, Losers | The New Yorker
If we could just synchronize our sleep more closely with natural light patterns, it would become far easier to wake up. It wouldn’t be unprecedented. In the early nineteenth century, the United States had a hundred and forty-four separate time zones. Cities set their own local time, typically so that noon would correspond to the moment the sun reached its apex in the sky; when it was noon in Manhattan, it was five till in Philadelphia. But on November 18, 1883, the country settled on four standard time zones; railroads and interstate commerce had made the prior arrangement impractical. By 1884, the entire globe would be divided into twenty-four time zones. Reverting to hyperlocal time zones might seem like it could lead to a terrible loss of productivity.
