A study of 93,249 adults has identified associations between specific sleep patterns and biological markers of aging, according to researchers who analyzed data from the UK Biobank. The findings, reported in August 2026, suggest that both the duration and consistency of sleep correlate with measures reflecting how the body’s cells maintain health over time. The analysis drew on participants who wore wrist-based activity trackers for seven consecutive days.
