PDHPE (Personal Development, Health and Physical Education) is an important subject in primary schools for several reasons. Statistics show that many Australian children aged 5-17 are overweight or obese, so PDHPE educates students on health risks and prevention through physical activity. PDHPE promotes lifelong physical activity, teaches decision making skills, and supports student wellbeing. It also provides instruction on topics like healthy lifestyles, human sexuality, safety, and preventing issues like bullying and depression. PDHPE is considered essential as it helps students be healthy and focused, improving performance in other subjects, and teaches skills to lead productive lives.
