Recent research suggests that habitual daytime napping may contribute to better brain health and cognitive function as we age.
A study conducted by University College London found a causal link between regular napping and larger total brain volume, a marker associated with a reduced risk of neurodegenerative diseases.
The researchers concluded that, for some individuals, short daytime naps could be a valuable component in preserving brain health over time.
The study found that people genetically predisposed to nap had, on average, a larger total brain volume equivalent to a brain 2.6 to 6.5 years younger.
However, it’s important to note that the benefits of napping are influenced by factors such as duration and frequency.
A systematic review highlighted that short to moderate naps, typically less than 90 minutes, were associated with improved cognitive health in older adults. In contrast, longer or more frequent naps were linked to poorer cognitive outcomes. Therefore, while incorporating brief naps into daily routines may support brain health, excessive daytime sleepiness or extended napping could indicate underlying health issues and should be discussed with a healthcare provider.
