Daytime sleep Is there any benefit from daytime sleep? An interesting article was published in Sleep Health magazine in 2023: "Is there an association between daytime napping, cognitive function, and brain volume? A Mendelian randomization study in the UK Biobank Valentina Paz et al. Sleep Health. 2023 Oct." Sample: 378,932 participants Method: Genetic analysis of daytime sleep habits and neuroimaging data Results People who regularly sleep during the day have a larger total brain volume. Such sleep promotes cognitive resistance to age-related decline in function. Regular daytime sleep is associated with a slowdown in brain aging by 2.6–6.5 years. Genetic analysis has shown that daytime sleep habits correlate with a 15.8 cm3 increase in total brain volume, which is associated with a lower age-related decrease in brain volume and neuroprotection.

Duration and cognitive benefits ⏳ 10-20 minutes → Ideal for a quick burst of energy ⏳ 30-60 minutes → Provides some cognitive benefits, but may cause temporary drowsiness ⏳ 90 minutes → Supports brain recovery, learning and memory
