A nap in the middle of the day is a good idea? In fact, not that very much

We constantly remember the kindergarten when daytime sleep was an obligatory part of the schedule, as the most beautiful time in life. And, just because of the opportunity to take a nap, which is so lacking today. However, if you are working on freelancing, you can brag of a free schedule or work in a company where all conditions are created for a day’s sleep, it is likely that you are still using this method of restoring your energy. Is it reasonable? Scientists have found out that not quite (in any case, if we talk about the function of memory).

Researchers from the University of Lancaster (Lancaster University) came to the conclusion that short periods of sleep during the day can create false memories. In a small experiment, the results of which were published in the journal Neuropsychologia, the authors of the study John Shaw and Padraic Monaghan found that healthy adults who slept for about 90 minutes in the middle of the day did worse tests for word recognition in compared with those who did not sleep during the day.

By monitoring the brain activity of participants with a polysomnograph, scientists were able to identify the potential cause of memory impairment after a nap – the type of brain wave known as the sleep spindle. The spindle is a burst of neuronal activity that happens during shallow sleep (the second phase of sleep), and is most likely associated with the formation of memories and the consolidation of memory.

Previous studies, IFL Science recalls, showed that when people are first given a list of thematically related words (bed, rest, sleep, pillow) and then they go to take a nap, then upon awakening they often falsely identify the given words. Being thus absolutely sure that all or almost all remember well. Studies have also shown that the right hemisphere of the brain , associated with abstract associations of words and concepts, is more inclined to create these false memories. Just in the hope of finding out what kind of brain mechanism is causing this curious phenomenon, Shaw and Monaghan conceived their experiment.

 As expected, those of the 32 participants who managed to take a nap were more often mistaken, calling the words demonstrated a few hours before. But the researchers noticed that the frequency of the spindles of sleep correlated with the number of false memories, which, in their opinion, should have been blamed for what was happening.

At the same time, scientists recognize that for the final conclusions they need more research, much more ambitious than this. In the meantime, they advise people to be wary of the habit of taking a nap in the middle of the day. At least those of us whose work requires utmost concentration and attention to detail.
