Can taking naps enhance brain health?

Jun 25, 2023

A recent study has explored the causal relationship between habitual daytime napping and brain health. Using Mendelian randomisation, it revealed a modest causal link between regular napping and larger total brain volume, providing insights into the potential cognitive benefits of daytime napping.

 

Key takeaways: Is there an association between daytime napping, cognitive function, and brain volume? A Mendelian randomization study in the UK Biobank

 

  • Causal link to brain volume: The study suggests a modest causal association between habitual daytime napping and a larger total brain volume, which is a critical aspect considering that brain volume often decreases with age
  • Potential Protective Role: The findings hint at the potential protective role of daytime napping in preserving brain volume, albeit the associations are modest and further research is needed to explore this in-depth
  • Genetic Factors: The study utilised genetic variants to explore these associations, providing a nuanced perspective that considers the genetic predispositions related to daytime napping and brain health
