A recent study has found that certain daytime napping habits among older adults may be linked to a higher risk of mortality. While naps are often considered refreshing and beneficial, researchers suggest that longer, frequent, or poorly timed naps could indicate underlying health concerns rather than being harmful on their own.
The study, published in JAMA Network Open, tracked 1,338 adults aged 56 and above over several years using wearable devices to monitor their sleep patterns. Unlike earlier research that relied on self-reported data, this study used objective measurements, making its findings more reliable.
Key findings
Researchers observed that three main napping patterns were associated with increased mortality risk:
- Longer naps were linked to higher risk
- Frequent naps during the day also raised the risk
- Morning naps showed a stronger association with mortality compared to afternoon naps
Interestingly, irregular nap duration (varying nap lengths) did not show a clear connection to mortality, suggesting that consistency alone is not the main issue.
Why morning naps may be concerning
One of the most notable findings was the higher risk associated with morning napping. Experts believe this could be related to disruptions in the body’s internal clock, or circadian rhythm. Morning naps may signal:
- Poor quality sleep at night
- Excessive daytime fatigue
- Possible neurological or metabolic disorders
In contrast, short naps taken in the early afternoon may align more naturally with the body’s daily rhythm and are generally considered less concerning.
Naps are not necessarily harmful
Despite these findings, researchers emphasize that napping itself is not dangerous. Short and occasional naps can improve alertness and reduce fatigue. The concern arises when naps become too long, too frequent, or occur at unusual times, as these patterns may reflect deeper health problems.
Previous studies have also linked excessive daytime sleepiness to conditions such as:
- Cardiovascular disease
- Neurodegenerative disorders
- Poor overall health
This suggests that napping may act more as a warning sign rather than a direct cause of increased mortality.
What older adults should watch for
Experts advise paying attention to certain sleep habits, especially in later life. Potential warning signs include:
- Naps lasting longer than an hour
- Multiple naps throughout the day
- Regular morning sleep episodes
If these patterns are observed, it may be useful to consult a doctor to assess sleep quality and overall health.
Conclusion
The study highlights that daytime napping patterns—particularly long, frequent, and morning naps—may be associated with a higher risk of death in older adults. However, the findings do not prove that naps cause health problems. Instead, they suggest that such sleep habits could reflect underlying medical issues that need attention. Monitoring sleep behavior, especially with modern wearable devices, could help detect potential health risks early and improve long-term well-being.
