科学60秒:摇啊摇,摇到美梦乡
They [--2--] 12 healthy males, all good sleepers. Each volunteer twice took an afternoon nap in a dark room on a [--3--] bed that could rock. For one nap, the bed was still. For the other, it rocked gently.
All the men fell asleep faster when they swayed. And the scientists monitored the men’s brain activity during all the naps. They found that rocking increased the [--4--] of what’s called N2, a non-REM stage that accounts for about half of a good night’s sleep.
Rocking also increased deep-sleep-associated brain activity—so-called slow oscillations as well as bursts of action called sleep spindles. The research was published in the journal Current Biology. [Laurence Bayer et al, Rocking synchronizes brain waves during a short nap]
The next step is to find out whether rocking can help treat [--5--]. Meanwhile, insomniacs can always try a hammock.
