Daytime Nap linked to Brain Health? Study reveals

daytime nap

A recent study conducted by researchers from the University College London (UCL) and the University of the Republic of Uruguay has some interesting findings. The study revealed that taking daytime naps may have a positive impact on maintaining brain health during the aging process.

However, it is important to note that excessive napping can potentially have detrimental effects. The study found that individuals who engaged in habitual napping had larger total brain volume. Which is associated with a reduced risk of dementia and other age-related diseases.

Take a Daytime Nap for better brain health

On average, individuals who regularly took daytime naps had a difference in brain volume equivalent to a decrease in aging effects by 2.5 to 6.5 years. This suggests that napping might contribute to the preservation of brain health. And potentially help in mitigating cognitive decline as people grow older.

“Our findings suggest that, for some people, short daytime naps may be a part of the puzzle that could help preserve the health of the brain as we get older”. Senior author Victoria Garfield, a senior research fellow at UCL, said in a statement.

These findings highlight the potential benefits of incorporating daytime naps into our daily routines, especially for older adults. However, it is crucial to strike a balance, as excessive or prolonged napping may lead to negative outcomes. Further research is needed to understand the optimal duration and frequency of napping for maintaining brain health.

Self-Reported Study

Tara Spires-Jones, the president of the British Neuroscience Association and deputy director of the Centre for Discovery Brain Sciences at the University of Edinburgh, who was not involved in the study, acknowledged that the study was “well-conducted.” However, she also pointed out that it was “self-reported”.

Self-reported data can be subject to recall bias. And may not always accurately reflect the actual napping habits of individuals. In this case, relying solely on self-reported information about napping frequency. And also duration could introduce some degree of inaccuracy into the study’s findings.

In short, Sleep is Good!

The results show “a small but significant increase in brain volume in people who have a genetic signature associated with taking daytime naps”. She told the Science Media Centre.

“Even with those limitations, this study is interesting because it adds to the data indicating that sleep is important for brain health,” she said.
