Science shows that sleep is essential to memory and creativity. As the NY Times reported, “Sleep improves creative ability to generate aha! moments and to uncover novel connections among seemingly unrelated ideas.” But what if we’re going about sleep all wrong?
Most humans in the industrial world sleep in one long stretch. We go to bed, sleep for 7 or 8 hours if we’re lucky, and then get up and go to work. But, as a recent New Yorker piece by Elizabeth Kolbert explains, this isn’t the way we always slept. And it may be why nearly two thirds of Americans claim that they’re not getting enough rest during the week.
Wolf-Meyer refers to the practice of going to bed at around eleven o’clock at night and staying there until about seven in the morning as sleeping “in a consolidated fashion.” Nowadays, adults are expected to sleep in this manner; anything else–sleeping during the day, sleeping in bursts, waking up in the middle of the night–is taken to be unsound, even deviant. This didn’t use to be the case.
Until a century and a half or so ago, Wolf-Meyer observes, “Americans, like other people around the world, used to sleep in an unconsolidated fashion, that is, in two or more periods throughout the day.” They went to bed not long after the sun went down. Four or five hours later, they work from their “first sleep” and rattled around–praying, chatting, smoking, or making love.(Benjamin Franklin reportedly like to spend this time reading naked in a chair.) Eventually, they went back to bed for their “second sleep.”
Flickr founder Caterina Fake recently discussed her experiments with sleeping with shifts. And creative luminaries from Winston Churchill to Thomas Edison to Salvador Dali have been known to appreciate the art of intermittent sleep.
What’s your take? Are you looking for a better solution than “consolidated sleep”?
