Study Overview and Findings
A recent study published in *JAMA Network Open* on April 20, 2026, has established a significant correlation between excessive daytime napping and increased mortality rates among older adults. Conducted by researchers from Mass General Brigham and Rush University Medical Center, the study analyzed data from 1,338 participants aged 56 and older over a period of nearly 19 years. The findings indicate that longer and more frequent naps, particularly those taken in the morning, are associated with higher all-cause mortality rates.
The study utilized wearable devices to objectively measure napping patterns, marking a departure from previous research that relied on self-reported data. Key findings include that each additional hour of daytime napping is linked to a 13% increase in mortality risk, while each extra nap per day raises the risk by approximately 7%. Notably, morning nappers face a 30% higher mortality risk compared to those who nap in the afternoon.
Implications of Napping Patterns
The researchers suggest that excessive napping may serve as a warning sign of underlying health issues, including neurodegeneration and cardiovascular diseases. Lead author Chenlu Gao emphasized the clinical value of tracking napping patterns to identify high-risk individuals early. The study posits that excessive napping could indicate chronic conditions, sleep disturbances, or circadian dysregulation.
Criticism and Nuanced Perspectives
While the study presents compelling data, some experts caution against interpreting the findings as evidence of causation. Dr. F. Perry Wilson noted that the correlation between napping and mortality could reflect underlying health problems rather than napping itself being a direct cause of increased mortality. He pointed out that the study's observational design does not establish a causal link, and further research is needed to explore the relationship between napping and health outcomes.
Additionally, the study's limitations include its focus on a predominantly older, White population in northern Illinois, which may affect the generalizability of the results to more diverse groups. Critics also highlight that the study did not account for the quality of naps or the potential impact of irregular napping patterns.
Official Statements and Recommendations
The findings have prompted calls for the implementation of wearable daytime nap assessments in clinical settings. Researchers advocate for these assessments to help identify individuals at risk of health decline. Dr. Gao stated, “Now that we know there is a strong correlation between napping patterns and mortality rates, we can make the case to implement wearable daytime nap assessments to predict health conditions and prevent further decline.”
Experts recommend that while short, infrequent naps can be restorative, older adults should be cautious about excessive napping, particularly in the morning. Dr. Suzanne Salamon from Beth Israel Deaconess Medical Center advises limiting naps to 15-30 minutes and suggests that the best time to nap is early afternoon.
Conclusion
The study highlights the potential health risks associated with excessive daytime napping in older adults, suggesting that it may be an indicator of serious underlying health issues. As researchers continue to explore this relationship, the findings underscore the importance of monitoring napping patterns as a means of early health risk identification.
