Play benefits all children, and has protective and preventative functions. Yet there is not a single, universally agreed definition of child health, nor of children's play. This makes insights from around the globe, highlighting the under-recognized link between the two, highly valuable. Theorists and practitioners evidence the healing power of play and positive health outcomes through interventions ranging from hospital clowning in Palestine, health promotion in remote Australia, playrooms in Brazilian hospitals, palliative care in South Africa, therapeutic work with neglected and abused Romanian children, to restoring children's health following natural disasters in Japan, and changes in nomadic communities in Iran. Early years and teenage play are discussed, and both physical and mental health and well-being. This wonderful collection aims to inspire further discussion and sharing of good practices.
