Longitudinal digital phenotyping of activity rhythms and biological aging using commercial wearables.
Nature communications·August 22, 2026·PMID 42778576
Why it mattersConsumer wearables now provide longitudinal, free-living circadian data at scale, offering a practical window into biological aging trajectories. For clinicians focused on longevity and preventive care, these findings suggest that easily captured rest-activity rhythm metrics may help identify patients at risk for accelerated aging and guide personalized lifestyle interventions.
