Excessive Daytime Napping in Older Adults Could Signal Serious Health Risks, Study Warns
Do you often feel the urge to take a nap during the day? That irresistible pull towards the pillow in the afternoon might seem harmless, but new research suggests it could be a red flag for your health, particularly as you age. A groundbreaking study indicates that a 20-minute snooze or longer may be your body's way of signaling underlying issues that warrant attention.
Excessive Napping as a Health Indicator
Investigators from Mass General Brigham and Rush University Medical Center have uncovered that frequent daytime sleepiness in older adults is more than just a result of a restless night. Their findings, published in the journal JAMA Network Open, reveal that excessive napping in this demographic may serve as a warning sign for serious health concerns.
The study followed 1,338 older adults for up to 19 years, meticulously tracking their napping habits and associated mortality rates. The results showed that longer, more frequent, and morning naps were linked to higher mortality rates. Lead author Chenlu Gao, PhD, an investigator in the Department of Anesthesiology at Mass General Brigham, emphasized the clinical value of this discovery.
"Excessive napping later in life has been associated with neurodegeneration, cardiovascular diseases, and increased morbidity," Gao stated in a release. "Our study is among the first to demonstrate a connection between objectively measured nap patterns and mortality, highlighting the potential for early detection of health conditions through napping assessments."
Napping Patterns and Their Health Implications
Researchers observed that between 20% and 60% of older adults engage in napping. While occasional naps can be restorative, an increase in frequency with age is correlated with a wide range of health issues. Despite these associations, the relationship between napping and health in older individuals has not been thoroughly explored, with previous studies lacking objective data on nap timing and daily variability.
To address this gap, the team utilized data from the Rush Memory and Aging Project, a cohort study initiated in 1997 focusing on cognition and neurodegeneration in older, predominantly white individuals in northern Illinois. Starting in 2005, participants wore wrist activity monitors for 10 days to collect rest-activity data, enabling analysis of nap length, frequency, time of day, and day-to-day changes.
By 2025, the researchers had amassed 19 years of data from the 1,338 participants. Their analysis revealed that longer, more frequent, and morning naps were all associated with higher all-cause mortality during the follow-up period. Specifically, each additional hour of daytime napping per day correlated with approximately a 13% higher mortality risk, while each extra nap per day was linked to around a 7% increased risk. Morning nappers faced a 30% higher mortality risk compared to those who napped in the afternoon. However, irregular napping patterns did not show any significant association with increased mortality.
Correlation, Not Causation: Understanding the Link
Gao clarified that the study establishes a correlation, not causation. "Excessive napping likely indicates underlying disease, chronic conditions, sleep disturbances, or circadian dysregulation," she explained. "Now that we have identified a strong correlation between napping patterns and mortality rates, we can advocate for the implementation of wearable daytime nap assessments to predict health conditions and prevent further decline."
That innocent morning nap might feel refreshing, but if it becomes frequent and extends in duration, it could be your body conveying a crucial message about your health.
