Regular naps are good for the long-term health of our brain, research shows.
Habitual napping may help keep our brains bigger for longer and boost its overall health, according to a 2023 study by researchers at University College London (UCL) and the University of the Republic in Uruguay.
The researchers analysed data from 35,000 people, aged 40 to 69, who had taken part in a study by UK Biobank, a biomedical database ad research resource. They looked at previously identified DNA snippets associated with people who are habitual nappers.
Napping has been shown to be critical for the cognitive development of babies, with trials showing that they were unable to remember new tasks if they did not have a long nap soon afterwards.
But the benefits of napping for adults are less well understood. The participants in Garfield's study were aged between 40 and 69. "We tried to focus on that midlife point when people start to get diseases and [conditions] like diabetes and high blood pressure," she says.
The long-term benefits are only seen in people who regularly nap, stresses Garfield. "It has to be cumulative."
Studies show that napping between 1 pm and 4 pm can benefit physical and cognitive performance as well as mood. "You consolidate memories, for sure. Your reaction times might improve and there may be some improvement in terms of coordinated performance," says Morgan.
"Napping is usually a sign that you're not getting sufficient sleep," says Colin Espie, professor of sleep medicine at the University of Oxford. If you feel that you frequently need a daytime nap, it's important to ask yourself whether you are compensating for a sleep problem or a lifestyle choice preventing you from getting enough sleep at night, says Espie. "The main thing we should be trying to do is to protect nighttime sleep. We can't just graze on sleep like some animals do.
