Excessive napping may be a sign of more serious metabolic health issues.

Daytime naps, or “power-sleeps,” have long been embraced across cultures as a means to refresh and restore energy. However, recent research suggests that the details surrounding napping are crucial. A prospective cohort study published this week in JAMA Network, which examined over 1,300 patients, revealed that longer and more frequent naps during the day are linked to higher rates of all-cause mortality. The researchers observed a dose-response relationship: short naps (less than an hour) did not significantly raise mortality risk, while longer naps (one hour or more) were connected to a greater risk.
The researchers suggest that increased mortality risk might be tied to cardiovascular health issues; disruptions in sleep, circadian rhythm problems, and poor metabolic health may lead to frequent fatigue and a tendency to nap more often. This connection indicates that poorer metabolic health and cardiovascular risk factors could be driving excessive napping. Additionally, sleep apnea, a common cause of disrupted nighttime sleep, often results in daytime fatigue and a need to nap. The Mayo Clinic warns that untreated sleep apnea can lead to severe risk factors for mortality, such as type 2 diabetes, high blood pressure, heart failure, and metabolic syndrome, all of which pose significant health risks.
Despite these concerns, napping is not without its benefits. Numerous studies highlight the positive aspects of napping. The National Sleep Foundation explains that a 20-minute nap can help reduce daytime sleepiness and enhance learning and performance. For shift workers, naps can boost alertness and reaction times. Other advantages may include improved focus, better memory, enhanced mood, and stronger logical reasoning skills. However, the specifics of napping—such as duration and timing—are crucial. Quick naps of 15-30 minutes, as recommended by the Cleveland Clinic, are preferable to longer naps, which can leave individuals feeling disoriented and more tired. The timing of naps also matters; early morning naps may not be as beneficial as those taken later, while late-day naps can disrupt nighttime sleep patterns. Individuals should experiment to find the optimal timing, duration, and frequency that works for them. When done correctly, napping can offer numerous benefits such as enhanced cognitive function and restoration of the brain and body.
Ultimately, maintaining good metabolic health is crucial in assessing mortality risk. Adopting healthy diets, establishing consistent sleeping patterns, engaging in regular exercise, and having routine check-ups with healthcare professionals are essential strategies for improving overall health and longevity.
