Day Sleeping: Your Nap Patterns May Send Worrisome Signs About Dementia

Lucky you if you don’t experience daytime drowsiness on a sporadic basis. For many, sliding into a nap is not only an occasional luxury but a rite of passage when you hit your later years. While there may be nothing wrong with taking the odd nap when the mood strikes you, there may be trouble brewing if those naps become more frequent, as they may signal other health problems in your body, including a higher risk for dementia and a higher mortality risk.

Brand new research published by the Johns Hopkins Bloomberg School of Public Health and published in The Journals of Gerontology Series A explains what health consequences more frequent napping may signal. According to this research, frequent and unintended daytime napping is associated with a higher risk for dementia in older adults. The study tracked almost 1000 older participants for up to 10 years, and at the start of the research, all participants were free of dementia. What researchers found was that those participants who napped frequently, i.e., most days or even every day, had a 48% higher risk of developing dementia compared to those participants who rarely or never napped. Napping for brief periods- under 30 minutes- was also associated with a significantly higher risk of dementia. What’s not clear is whether these naps are a cause of elevated dementia risk or a signal of brain changes that are leading to dementia. There is likely a bidirectional relationship between napping and dementia- it may be a risk factor as well as a sign that regions of the brain that help regulate wakefulness are degenerating due to dementia.

What this research then suggests is that napping behaviors among older adults should be tracked and monitored. It’s not that you should never nap. Rather, changes in napping patterns may precede clinical signs of dementia by many years, and could be an early indicator that cognitive impairment is ahead.

Earlier research in 2026 also found an association between napping and underlying health concerns. In an important long-term study in JAMA Network Open, patterns of increased napping, for longer periods of time and earlier in the day, were associated with a higher risk of death. Again, researchers hypothesized that changes in daytime napping behaviors might serve as an “early warning” to older adults about underlying health conditions that might put them at risk of death. In this study, researchers followed over 1300 participants for up to 19 years. Compared to those whose napping patterns remained stable over time, those who napped more frequently or for longer periods, especially in the morning, were at higher risk of death. In essence, this study suggests that napping may reveal much more about our overall health than merely feelings of sleepiness. It may reflect such biological changes as circadian rhythm disruption, cardiovascular strain, or even early neurological changes. The occasional nap is not harmful, and no one is suggesting that when the mood strikes, you cannot close your eyes. But the more you nap, the more your new pattern may reflect underlying physiological changes that are important to note. So jot down your downtime and track your patterns, as there may be more at play than merely feeling tired.
