Study links frequent daytime napping to higher mortality in older adults
A recent study presented at SLEEP 2025, the 39th annual meeting of the Associated Professional Sleep Societies, has shed light on the potential risks associated with daytime napping in older adults. The study, conducted by lead author Chenlu Gao and his team at Massachusetts General Hospital, found that frequent, longer, and irregular daytime naps, particularly in the early afternoon, were linked to an increased risk of mortality over an eight-year period.
The study included 86,565 participants with an average age of 63, all of whom worked regular daytime schedules. Using actigraphy to monitor movement during sleep, researchers found that those who took longer naps and napped between 11 a.m. and 3 p.m. had a higher mortality rate. These results were adjusted for factors such as demographics, weight, smoking, alcohol consumption, and nighttime sleep duration.
While the study provides valuable insights into the potential risks of excessive daytime napping, it is important to note that the findings do not establish a direct causal relationship between napping and mortality. As Dr. Chelsie Rohrscheib, a neuroscientist and sleep specialist, pointed out, napping may not be problematic unless it is used to compensate for poor nighttime sleep.
It is also worth considering the limitations of the study, such as the reliance on movement detection rather than brain activity to determine sleep patterns. Additionally, excessive napping could be a sign of underlying health issues that may contribute to an increased risk of mortality.
Moving forward, more research is needed to fully understand the impact of napping on health outcomes. In the meantime, the American Academy of Sleep Medicine recommends limiting naps to 20-30 minutes in the early afternoon to avoid feeling groggy after waking up.
Overall, the study highlights the importance of moderation when it comes to daytime napping and suggests that napping patterns could serve as a valuable indicator of broader health concerns. By discussing napping habits with a medical provider, individuals can take proactive steps to address potential health issues and improve overall well-being.
In conclusion, while a midday snooze may seem appealing, it is essential to approach napping with caution and mindfulness of its potential impact on health. By staying informed and seeking guidance from healthcare professionals, individuals can make informed decisions about their sleep habits and overall health.
