But as early as the 1950s, researchers started debunking the idea of sleep learning. They recorded brain waves of sleeping subjects and showed that our brains don’t store information we hear while we sleep.
While scientists agree that we can hear information while we’re unconscious, modern studies show that we can’t process and learn it while we sleep (2). And for the last few decades, the verdict on hypnopedia in the scientific community has been unanimous: sleep learning doesn’t work.
So why are we still talking about hypnopedia today?
Despite the scientific evidence, people are fascinated by the idea of sleep learning — and some scientists still actively study it, hoping to discover a breakthrough.
Unfortunately, you can’t learn a language or skill while you sleep. But that doesn’t mean sleep can’t help you learn.
