Summary
This completed pilot study in Yomitan Village, Okinawa tested three simple, low-cost approaches to reduce stress and encourage healthy habits in 45 adults with overweight or pre-metabolic syndrome. Participants were randomly assigned to receive health leaflets, wear functional clothing, or follow a moderate exercise manual for eight weeks. The study measured fatigue, mood, sleep, and heart rate using a smart ring. The goal was to see if these everyday strategies are practical and acceptable for community-based prevention programs.
