An occasional nap can be normal, but changes in daytime sleep may signal more than simple fatigue. As we age, lighter nighttime sleep and earlier mornings can make afternoon rest feel increasingly natural. However, a steady increase in daytime sleep may be worth paying attention to, as it could reflect underlying changes in health.
According to new research, regularly taking long daytime naps, especially in the morning, may be linked to a higher risk of death from any cause. Short afternoon naps can still be healthy and refreshing, but frequent or lengthy daytime sleep may signal that something deeper is going on. The research suggests that when napping becomes too frequent or prolonged, it may reflect underlying health conditions rather than simply a need for extra rest.
Scientists gathered objective sleep data from a group of older adults by monitoring 1,338 retired participants over a 10-day period that wore wrist trackers. They measured not only how frequently people napped, but also the timing, duration, and day-to-day variability of those naps. Most volunteers were women, and the average participant was 81 years old.
Longer, more frequent, and earlier naps were all tied to higher mortality risk. Each extra hour of daytime sleep increased risk by 13%, each added daily nap by 7%, and morning napping was linked to a roughly 30% greater risk than afternoon napping.
Researchers emphasize that naps themselves are not harmful. However, longer, more frequent, or earlier naps may be a sign that something else is going on. Rather than just a habit, daytime sleep may sometimes act as a warning signal.

Objectively Measured Daytime Napping Patterns and All-Cause Mortality in Older Adults
Our daily routines and body rhythms tend to shift with age. Although chronological age is fixed by time, biological age reflects how well the body is functioning. A new study suggests that aging may affect circadian rest-activity rhythms, the body’s natural daily cycle that helps regulate wakefulness, activity, rest, and sleep.
Exercise may be one of the most powerful anti-aging tools we have. New research suggests it can switch aging muscles back into repair mode, helping them recover, rebuild, and stay stronger as we grow older.
An extensive review of American Heart Association health records showed that reduced strength and mobility were linked to increased stroke risk. The study identified a clear relationship between worsening physical performance and the chances of experiencing a stroke.
