Long naps may be more than a harmless habit—they could signal a higher risk of mortality in older adults, according to a new study. The research, which tracked over 1,300 adults aged 56 and older for nearly two decades, found that longer and more frequent naps were associated with an increased risk of death. But before you swear off your afternoon siesta, experts caution that the link doesn't prove naps cause harm; rather, they may be an early warning sign of underlying health issues.
Study Details: How Researchers Measured Nap Habits
The study, published this year, analyzed 1,338 adults with an average age of 56 or older. Participants wore actigraphy bracelets for 14 consecutive days, allowing researchers to objectively track sleep patterns. Naps were defined as any sleep period detected between 9:00 AM and 7:00 PM. The team then followed participants for 19 years, monitoring health outcomes.
This long follow-up period and objective measurement set the study apart from earlier research that relied on self-reported nap habits. By using actigraphy, researchers could capture nap duration, frequency, and timing without relying on participants' memory or awareness.
Key Findings: Duration, Frequency, and Timing Matter
The results showed a clear dose-response relationship: the more time spent napping, the higher the mortality risk. Specifically, each additional hour of daily napping was linked to a 13% increase in the probability of death. When it came to frequency, each additional daily nap was associated with a 7% higher mortality risk.
Timing also played a role. People who napped primarily in the morning had a 30% higher mortality rate compared to those who napped in the early afternoon—the traditional post-lunch siesta. This suggests that morning naps may be a red flag for disrupted nighttime sleep or other health problems.
- Each extra hour of daily napping was linked to a 13% higher mortality risk.
- Each additional daily nap was associated with a 7% increased risk.
- Morning nappers had a 30% higher mortality rate than early-afternoon nappers.
- The study followed participants for 19 years, providing robust long-term data.
- Actigraphy bracelets objectively measured nap duration and timing.
What the Numbers Really Mean: Association, Not Causation
It's easy to panic at these percentages, but the study does not show that napping causes death. Instead, it highlights an association: people who nap longer or more frequently are more likely to die over the follow-up period. This could be because excessive napping is a symptom of underlying health conditions, such as sleep disorders, cardiovascular disease, or early signs of neurodegeneration.
In other words, long naps might be a biological signal that something is wrong, rather than the cause itself. The researchers emphasize that napping is not inherently harmful—in fact, short naps can be beneficial for alertness and mood. The key is to pay attention to changes in nap habits, especially if they become longer or more frequent over time.
Why This Matters for Older Adults
For older adults, sleep patterns naturally change, and napping can become more common. However, this study suggests that monitoring nap habits could serve as a simple screening tool for health risks. If you or a loved one suddenly start napping much longer or more often, it may be worth mentioning to a doctor.

The findings also challenge the cultural acceptance of long siestas, particularly in countries like Spain where napping is a tradition. While a short post-lunch nap may be fine, prolonged or morning naps could warrant closer attention.

Comparison of Nap Patterns and Associated Risks
| Nap Characteristic | Associated Risk Increase | Notes |
|---|---|---|
| Each additional hour of daily napping | 13% higher mortality risk | Dose-response relationship observed |
| Each additional daily nap | 7% higher mortality risk | Frequency matters independently |
| Morning napping vs. early afternoon napping | 30% higher mortality risk | Timing may indicate disrupted circadian rhythm |
| Short, occasional afternoon naps | Not associated with increased risk in this study | Traditional siesta pattern |
What to Watch For and Next Steps
If you're an older adult or caring for one, keep an eye on nap patterns. A sudden increase in nap duration or frequency, especially in the morning, could be a sign to consult a healthcare provider. It's also important to maintain good sleep hygiene and address any underlying sleep issues. Earlier coverage in Adults Are More Creative Than Preschoolers, Study Finds shows how the argument developed.

Future research may explore whether interventions to reduce excessive napping can improve health outcomes. For now, the takeaway is not to fear naps but to view them as a potential window into overall health.

FAQ
Does this mean I should stop taking naps?
Not necessarily. The study shows an association, not causation. Short afternoon naps may still be beneficial. However, if your naps are long or frequent, it's worth discussing with a doctor.
Why were morning naps riskier than afternoon naps?
Morning naps may indicate poor nighttime sleep or a disrupted circadian rhythm, which can be linked to health problems. Afternoon naps, especially after lunch, are more in line with natural energy dips.
How was nap duration measured in the study?
Participants wore actigraphy bracelets for 14 days. These devices detect sleep periods between 9 AM and 7 PM, providing objective data on nap duration, frequency, and timing.
Should I be worried if I nap every day?
Daily napping itself isn't necessarily a problem, but the study found that each additional daily nap was linked to a 7% higher mortality risk. If you nap daily and feel unrefreshed or have other symptoms, consult a healthcare provider.
