This circular focuses on the importance of physical activity and healthy eating. It is acknowledged that mental and psychological well-being are a key part of healthy lifestyles. Schools support these through their work on anti-bullying and the SPHE curriculum. Schools and the wider education sector have a vital role to play in contributing to the ‘Healthy Ireland’ agenda that is being led by the Department of Health and is supported by the Department of Education and Skills and other Government Departments. Schools are contributing to the overall physical, mental health and well-being of our young people. But there are many challenges for our young people if they are to adopt a healthy lifestyle and enjoy positive health and wellbeing to their full potential. We can, in collaboration with parents and families, all do more to address these challenges. This circular aims to support and strengthen primary schools’ efforts in this regard.
