Elderly people who are used to taking naps during the day would thus preserve their brain. Indeed, a recent study published in Sleep Health studied the link between napping and brain volume. With aging, the latter tends to decrease in volume, to atrophy but the nap helps to slow down this process. By analyzing the brains of more than 300,000 people between the ages of 40 and 69, some of whom carry the genetic traces of their napping habit, scientists have shown that napping followers gain between 2.8 and 6, 5 years of ageing.
What are the benefits of a nap?
“Our results suggest that, for some people, short naps may be one of the factors that could help preserve brain health as we age,” explains Victoria Garfield, scientist who participated in the study. While naps seem to have a positive impact on brain volume, the study did not show the same benefits on hippocampal volume, reaction time or the brain’s processing of visual information. The beneficial or negative effects of napping on health are still widely debated in the scientific community.
