STUDY: 45 minute power nap boosts memory five-fold... -
A power nap of just 45 minutes can boost memory by five times, research has found.
A short doze helps you to retain information you have learned and 'significantly' improves recall, scientists said – meaning naps really could help students revising for exams.
Participants in the study learned 90 single words and 120 unconnected word pairs such as 'milk taxi'.
Happy napping: A 45-minute nap helps you to retain information you have learned and 'significantly' improves recall, scientists said – meaning naps really could help students revising for exams
Sleep study: The scientists at Saarland University found that a nap 'produces a five-fold improvement in information retrieval from memory'
Some then watched a DVD while others slept.
When they were then retested, those who had slept remembered more word pairs, the journal Neurobiology of Learning and Memory reports.
The scientists, from Saarland University in Germany, said that during sleep, bursts of brain activity known as sleep spindles play an important role in consolidating newly learned information.
Professor Axel Mecklinger said a nap of just 45 minutes to an hour 'produces a five-fold improvement in information retrieval from memory'
'The memory performance of the participants who had a power nap was just as good as it was before sleeping, that is, immediately after completing the learning phase.
'Strictly speaking, memory performance did not improve in the nap group relative to the levels measured immediately after the learning phase, but they did remain constant.'
'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.'
