Daytime Naps Make Your Brain Healthy, Study Reveals!

Who doesn’t love a good nap? But did you know that daytime naps can actually benefit your brain health? For years, napping during the day has been seen as a sign of laziness or unproductivity. However, research has started to uncover the positive effects that a well-timed nap can have on our brain function and overall well-being. These are some surprising benefits of sneaking in a quick snooze during the day.

Daytime Naps Could Be Beneficial

New research led by UCL and the University of the Republic in Uruguay suggests that regular daytime naps may be beneficial for brain health. The study indicates that daytime napping could potentially slow the rate at which the brain shrinks with age. The researchers aim to diminish any existing stigma around daytime napping by highlighting its potential health benefits.

What Does the Study Suggest?

The study indicates that habitual nappers have a significant difference in brain volume compared to non-habitual nappers, equivalent to 2.6 to 6.5 years of aging. The research suggests that a daily 30-minute nap may contribute to slowing down the process of brain shrinkage. Dr. Victoria Garfield, the senior author, notes that short daytime naps could be a potential factor in preserving brain health as individuals age.

What Did the Daytime Naps Study Consider?

The study, published in Sleep Health, examined data from individuals aged 40 to 69 to explore a potential causal relationship between daytime napping and brain health. Previous research has indicated that those who take short naps perform better in cognitive tests in the hours following the nap.

In a study examining 97 DNA segments associated with habitual napping, researchers analyzed data from 378,932 individuals in the UK Biobank study. Those genetically predisposed to napping showed a larger total brain volume. The genetic variants influencing the likelihood of habitual napping were previously identified in a study involving 452,633 UK Biobank participants.

What the Study Has Yet to Reveal

The study revealed a larger total brain volume in those genetically predisposed to habitual napping. However, there was no observed difference in performance on three other measures of brain health and cognitive function. Lead author Valentina Paz, a PhD candidate, emphasized that this study is the first to explore the causal relationship between habitual daytime napping and cognitive and structural brain outcomes. The use of Mendelian randomization, based on genes set at birth, helps mitigate confounding factors. These may influence associations between napping and health outcomes throughout one’s life.

The study suggests a causal connection between habitual napping and a larger total brain volume. While the impact of napping on preventing diseases like Alzheimer’s remains uncertain, maintaining overall brain health is considered important for safeguarding against dementia.
