45 minutes Power Nap could improve memory by five times: Research
A Power Nap of 45 to 60 minutes can improve the memory by five times, according, to a new research conducted by a team at Saarland University in Germany. The research team found that short nap increased the recall function significantly. Many students take a nap while preparing for exams and now the study has further cemented that notion.
Study lead Professor Axel Mecklinger said that a nap of just 45 minutes offered nearly five-fold improvement in the information retrieval from memory. The study included 41 individuals who were given 90 words and 120 unrelated word pairs. Half of the study subjects were asked to take a power nap while the other half watched a movie.
The research team found that the individual who had power nap, were much better in recalling the words, by as much as five times. The research team concluded that students could perform better during exams if they take short nap after learning. The napping group was tested using an EEG for "sleep spindles," which are bursts of activity in the brain during sleep.
Mecklinger added, “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.”
The research team informed, “We suspect that certain types of memory content, particularly information that was previously tagged, is preferentially consolidated during this type of brain activity.”
Detailed research findings have been published in the journal Neurobiology of Learning and Memory.
