Abstract
Prior to this study, we digitized the counseling technique SAT (Structured Association Technique) method used in industrial clinics and developed a self-mental care course (SAT-VR method) for smartphones and VR, and confirmed its efficacy and safety. The SAT-VR method uses images such as light, color, and shape to change the physical discomfort of the stressful scene to a sensation of good physical comfort, and to relax body tension. In this study, female managers who were more likely to have somatic complaints and fatigue as stress reactions were examined for stress reduction using subjective indices and heart rate variability before and after the implementation of the SAT-VR method. After implementation, anxiety, depression, self-esteem, need for counseling, and emotional support network significantly improved, and immediately after implementation, significant instantaneous heart rate decline, increased parasympathetic activity (HF) and total power (LF+HF), and a tendency to relax were confirmed. Ethics. Entire experimental protocols were approved by the ethics committee
