The research teams draws a clear conclusion from its study: ‘A short nap at the office or in school is enough to significantly improve learning success. Wherever people are in a learning environment, we should think seriously about the positive effects of sleep,’ says Axel Mecklinger. Enhancing information recall through sleeping doesn’t require us to stuff bulky tomes under our pillow. A concentrated period of learning followed by a short relaxing sleep is all that’s needed.

Generations of school students have gone to bed the night before a maths exam or a vocabulary test with their algebra book or vocabulary notes tucked under their pillow in the hope that the knowledge would somehow be magically transferred into their brains while they slept. That they were not completely taken in by a superstitious belief has now been demonstrated by a team of neuropsychologists at Saarland University, who have shown that even a brief sleep can significantly improve retention of learned material in memory.
Sara Studte, a graduate biologist specializing in neuropsychology, working with her PhD supervisor Axel Mecklinger and co-researcher Emma Bridger, is examining how power naps influence memory performance. The results are clear: ‘Even a short sleep lasting 45 to 60 minutes produces a five-fold improvement in information retrieval from memory,’ explains Axel Mecklinger.
Strictly speaking, memory performance did not improve in the nap group relative…
