Aging & Healthy Rhythms Research Lab

The Aging & Healthy Rhythms Research Lab focuses on understanding changes in the “daily rhythms” of routine health behaviors in the wake of stressful life events common in later life like spousal/partner death. Our goal is to identify risk factors for rhythm disruptions, and to develop and test interventions to help older adults to stabilize daily patterns of activities and thereby avoid common complications of major life stressors (e.g., decrements in health and well-being; increased depression).

We explore exactly how the 24-hour rhythm of daytime activity and nighttime sleep – also known as the circadian rest-activity rhythm – becomes disrupted during major life events. Understanding the rest-activity rhythm in bereaved individuals is essential for targeting when their behavioral activities should be scheduled in order strengthen their biological clock and prevent adverse health effects of bereavement.
