Long Naps at Irregular Times Linked to Higher Death Risk

A new study from Harvard Medical School and Massachusetts General Hospital reveals that long naps at irregular times may increase the risk of death. The research, which analyzed data from over 86,000 adults, suggests that napping habits can be significant indicators of health risks. According to the New York Post, napping for longer durations and at inconsistent times, particularly between 11 a.m. and 3 p.m., is associated with a higher mortality risk.

The study, presented at the SLEEP 2025 conference, found that long naps might reflect underlying health issues such as cardiovascular disease, metabolic disorders, or early neurodegenerative changes. The Daily Mail reported that those who nap irregularly or for extended periods may also have a higher body mass index, elevated blood pressure, and a greater prevalence of metabolic syndromes, which can lead to obesity, diabetes, and heart disease.

Lead researcher Professor Chenlu Gao emphasized that while napping is part of the sleep-wake cycle, its patterns can indicate future health risks. The findings suggest that daytime sleepiness might be a warning sign of poor-quality nighttime sleep or underlying health problems. Experts recommend that doctors inquire about patients' napping habits to better assess health risks.

While the study highlights associations, it does not establish a direct cause-and-effect relationship. The research underscores the importance of considering napping behaviors when assessing health risks, especially in middle- to older-aged adults.
