Sleep regularity and mortality: a prospective analysis in the UK Biobank

This study explored how irregular sleep-wake patterns influence mortality in 88,975 adults using data from the UK Biobank. Participants wore accelerometers for seven days to assess sleep regularity. Results revealed that those with more irregular sleep schedules had a 53% higher risk of death from any cause compared to those with average regularity. The findings suggest that consistent sleep patterns may help reduce risks for cardiovascular disease, cancer, and overall mortality. The study highlights the importance of circadian rhythm in maintaining long-term health and brain function.

To enhance health and longevity, prioritize a consistent sleep schedule by sleeping and waking at similar times daily. While this recommendation is backed by large-scale observational data, it is important to note that causation has not been firmly established. Individual needs and other health factors should also guide sleep practices.
