A short afternoon nap not only regenerates but may even improve our cognitive abilities and ward off Alzheimer's. This is what a new study claims.

If after lunch you feel a certain tiredness, you should more often give in to the temptation to indulge in a "nap". A short afternoon nap, in fact, especially if you are over 60, could have several benefits for your mind.

A recent study, published in General Psychiatry, argues that resting in the afternoon 4 times a week for up to 30 minutes could improve cognitive skills and in particular help to have a sharper memory, better language skills and a higher level. of space awareness.

The research was conducted on the sleeping habits of 2.214 Chinese seniors whose cognitive abilities were assessed using different tests for memory, language and other mental skills. Participants were divided into two groups: those who took regular naps and those who didn't.

By "rest" the study means a period of sleep after lunch lasting between five minutes and two hours.

The results showed that the afternoon rest positively influenced the mental abilities of the elderly but this had to be short, lasting less than 30 minutes.

“Longer and more frequent naps have been associated with poor cognitive function. In contrast, short (less than 30 minutes) and frequent (four times a week) naps were associated with an 84% reduced risk of developing Alzheimer's disease, ”the study reads.

The authors are keen to underline that it is necessary to deepen the topic better and understand how the afternoon rest can affect cognitive function. Among other things, the study was conducted on over 60s and in China, so it is necessary to understand if the results obtained are also valid elsewhere and for other age groups.

In the meantime, we can take a siesta when necessary (and if possible) but without exaggerating, to avoid waking up groggy and then having a hard time falling asleep in the evening.
