This article analyzes the effectiveness of psychological and physiological approaches in preventing autonomic nervous system (ANS) dysfunction in primary school-aged children. The study involved 120 children aged 6–10 years, who were divided into experimental and control groups. The experimental group received stress management exercises, emotional intelligence development activities, physical exercises, and breathing techniques. The results showed that the integrated approach significantly improved heart rate, blood pressure, stress index, and sleep quality in children. The study indicates that psychological and physiological prevention programs are effective tools for enhancing autonomic nervous system stability and improving school adaptation in primary school-aged children.
