A recent study has revealed that a short nap or a power nap of just 45 minutes can boost memory by five times.
It will help retain information you have read and it improves retrieving learnt information so naps are very necessary before the exams it could help revising.
The participants were split into two groups one group is the control group and other is the nap group.
The control group is the group who watched DVD’s and the other group is the group who took a nap.
During the performance test it was noted that the nap group performed better in remembering the word pairs than the other group.
Hippocampus is the region of the brain in which memories are consolidated and it is the process by which previously learned information is transferred into long term memory storage.
The researchers examined ‘sleep spindles’ a particular brain activity which plays an important role in memory consolidation during sleep.
A sleep spindle is a short burst of rapid oscillations in the electrocenphalogram(EEG).
Dr. Axel Mecklinger, who supervised the study, said, “We suspect that certain types of memory content, particularly information that was previously tagged, is preferentially consolidated during this type of brain activity.”
The greater the number of sleep spindles appearing in EEG, the stronger is the memory of the person.
