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.

Being alone isn't necessarily harmful, but feeling lonely may be. According to a new study, older adults who experience persistent loneliness may face a faster decline in both cognitive and physical health. The researchers found that loneliness remained strongly linked to poorer brain health and an increased risk of early death, regardless of how socially isolated a person was.
Imagine being able to preserve your healthiest blood stem cells while you're young, then using them decades later to help rejuvenate your body. New research in mice suggests it may one day be possible to restore a more youthful blood-forming system and immune system by transplanting young stem cells later in life.
The gut microbiome is the community of trillions of bacteria, fungi and viruses that primarily live in the colon. These tiny organisms help digest food while producing compounds that can influence many aspects of both physical and mental health. Researchers have uncovered a link between specific gut bacteria and biological aging, adding to growing evidence that the gut microbiome may affect how we age.
