It’s safe to say that napping, even though it may seem like it isn’t, is a much talked about topic. Some need that rest period, generally after eating. There are also those who think a lazy habit.

However, others do not consider it synonymous with laziness, but warn that oversleeping can be dangerous. However, the more that is heard and the more experts say that, if the nap isn’t too long, it’s quite beneficial.

recentlyStudy published by a team of scientists from the United States, United Kingdom, and Uruguay confirms this, but also adds that genes and brain volume are linked to everyone’s perfect nap.

As we already know, adequate sleep is very important for preventing metabolic and cardiovascular diseases and even some types of cancer. In addition, it is also very useful for keep your mind fit. When we sleep, we help consolidate memories, so it’s great for memory and cognitive health.

It is for this reason that these scientists wanted to see if people who usually nap have better brain health, and actually a positive link has been found. Of course, it won’t work if you sleep all afternoon. The perfect nap takes place less than half an hourAlthough lazy to get up so early. Otherwise, the so-called “bounce effect” occurs. If you nap too long, you will usually feel more tired than when you fell asleep.

the importance of genes

The researchers analyzed role of DNA in a tendency to nap. To do this, they collected data from 378,932 people whose ages ranged from 40 to 69 years. They all underwent brain scans, genetic analysis and surveys about their sleeping habits.

Thanks to this, it was found that there are 92 sections of DNA associated with people taking regular naps. In addition, it is also seen that most of them have a larger brain volumethe equivalent of a person between 2.5 and 6.5 years younger.

Therefore, napping improves one of the parameters related to brain age.
