Daytime Napping Habits Linked to Mortality Risk in Older Adults: New Research

New research indicates that daytime napping habits,specifically longer naps and inconsistent timing,may be associated with increased mortality risk,particularly among older adults. The findings, presented in the journal Sleep, highlight the importance of considering napping behaviors in assessing health risks. The study followed over 86,000 participants in the United Kingdom, aged 43 to 79, to evaluate the connection between daytime naps and mortality rates.

Key Findings on Napping and Longevity

Researchers analyzed self-reported napping habits alongside data from activity trackers. They considered factors such as chronotype, body mass index (BMI), demographics, existing health conditions, nighttime sleep patterns, smoking, and alcohol consumption. The analysis revealed that longer naps, increased variability in nap length, and napping around noon or in the early afternoon were associated with a greater risk of mortality.

The study suggests that incorporating nap assessments into clinical and public health practices could be valuable in promoting longevity. However, more research is needed to fully understand the underlying mechanisms.

Expert Insights on Napping Patterns

Ashley Curtis, Ph.D., assistant professor and director of the Cognition, Aging, Sleep, and health (CASH) Lab at the University of South Florida, offers additional perspective on the research. She cites research showing that the mortality risk associated with longer daytime napping in older adults might potentially be lowered by certain lifestyle factors such as physical activity. Meeting the recommended weekly dosage of moderate-to-vigorous physical activity (150 minutes of moderate intensity or 75 minutes of vigorous activity) can weaken the association between napping and mortality risk. Physical activities for older adults could include fast walking or jogging, dancing, swimming, or hiking.

Nuances in the Napping-Mortality Relationship

Curtis adds that the relationship between napping and mortality might potentially be more nuanced in older adults and depend on sex differences in the prevalence of sleep disorders. At least one study has shown that in older men, those who slept less than six hours and napped more than 30 minutes during the day had a higher risk of mortality. The same pattern wasn’t found in women.

Compared to older women,older men have higher rates of frequent nighttime urination and obstructive sleep apnea,both of which are linked to greater daytime sleepiness.

pro tip: Consider consulting a sleep specialist if you experience excessive daytime sleepiness or have concerns about your sleep patterns.

The Complexities of Napping and Mortality

The longer napping and increased mortality relationship findings in older adults are largely consistent. However, the exact mechanisms underlying this relationship have not been fully determined. The napping and mortality relationship is complex and may be influenced by adverse or protective lifestyle factors (e.g.,nutrition,physical activity,substance use),nighttime sleep patterns,and underlying sleep disorders,medical comorbidities,age,as well as sex and gender-related factors.

While more research is needed in this area, this study offers hope in identifying some early predictors of increased mortality and new clinical approaches for promoting longevity.
