The study is designed to assess the relationships between sleep quality, balance capabilities, and cognitive functions in older adults. Using a longitudinal approach, participants will be monitored over six weeks with the help of wearable technology (OURA ring) and standardized assessments. Weekly in-person visits will include balance assessments using the Mini-BESTest and mobility tests such as the Timed Up and Go (TUG) test. Cognitive functions will be evaluated using the NIH Toolbox Cognitive Battery. The study aims to identify key sleep indicators that influence balance and cognition, ultimately contributing to improved strategies for maintaining the health and well-being of older adults.
