“Learn a new language while you sleep!” may sound like the start of a bad 3 a.m. infomercial, but new research has found some evidence for sleep learning. Of course, listening to French on tape while you sleep is unlikely to instantly give you the ability to order a vanilla latte and an omelet in a foreign tongue the next morning. But it may enhance your ability to learn new vocabulary, according to a study published in Current Biology.
Researchers have long known that sleeping plays an important role in the learning process. While we catch Z’s, our brains are busy organizing and consolidating the information and events we encountered that day. Important stuff gets filed away, while unimportant stuff gets deleted to make room for new learning. Yet scientists didn’t think it was possible to actually learn new things while we sleep. They thought our brains were too focused on the nightly housekeeping. But a new study from the Decoding Sleep Interfaculty Research Cooperation at the University of Bern, Switzerland, has shown that the brain’s channels for learning are also open during sleep.
