PDHPE (Personal Development, Health and Physical Education) is important in primary school for several reasons. It addresses issues like childhood obesity and inactivity by encouraging physical activity. Regular physical activity through PDHPE provides health benefits like improved bone and heart health and obesity control. PDHPE also helps students develop self-confidence by providing guidance on personal health choices and understanding life changes and personal development. It teaches students to value themselves and others by forming positive relationships and communicating cooperatively.
