Feasibility Trial of Functional Clothing, Moderate Exercise, and Health Information for Stress Reduction and Behavior Change in Okinawa
Sponsor: Shinyu Kise
Summary
This study is a pilot randomized trial conducted in Yomitan Village, Okinawa, Japan. The purpose is to evaluate whether three simple, low-cost interventions can help reduce stress and support healthy behavior change in community-dwelling adults. The interventions are: (1) providing health information through educational leaflets, (2) wearing functional clothing designed to support physical comfort, and (3) practicing moderate exercise using a simple manual. A total of 45 adults, aged 20 to 65 years, with overweight or pre-metabolic syndrome will be recruited. Participants will be assigned randomly into one of the three groups. The study duration is eight weeks. Outcomes include fatigue scores, mood states, sleep quality, and heart rate variability measured by a smart ring. Data will be collected at baseline and after eight weeks of intervention. This study aims to test whether these approaches are feasible, safe, and acceptable for residents. The results will help design larger studies in the future and provide evidence for community-based prevention programs that are easy to adopt in daily life.
