According to researchers, a power nap of just 45 minutes can boost memory by five times. This has immense benefit particularly for students as a short doze helps to retain information you have learned and ‘significantly’ improves recall.
Of course it’s difficult to wake up after such a short nap when you are really tired—and that is why most people avoid it but considering the benefits, its worth the struggle.
Scientists from Saarland University in Germany who conducted the research say; 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.’
So that is it for you, especially the students. Sleep is always important but power nap is also really needed.
