PDHPE (Personal Development, Health and Physical Education) in schools is important for three main reasons: 1) It helps students develop self-esteem, positive attitudes, and good relationships by teaching them to make healthy lifestyle choices. 2) It allows students to be physically active and learn skills for different sports and fitness in a safe environment with peers. 3) The personal health and development component teaches students how to live safely and healthily by covering topics like nutrition, bullying prevention, and sexual education.
