Experiences in nature are now recognised as being fundamental to human health and well-being. Physical activity in nature has been posited as an important well-being facilitator because the presence of nature augments the benefits of physical activity while also enhancing motivation and adherence. This volume brings together a mix of cutting edge ideas in research, theory and practice from a wide set of disciplines with the purpose of exploring interdisciplinary or trans-disciplinary approaches to understanding the relationship between physical activity in nature and health and well-being. Nature and Health: Physical Activity in Nature is structured to facilitate ease of use for the researcher, policy maker, practitioner or theorist. Section 1 covers research on physical activity in nature for a number of important health and well-being issues. Each chapter in this section considers how policy and practice might be shaped by current research findings and knowledge. Section 2 considers contemporary theoretical and conceptual understandings that help explain how physical activity in nature enhances health and well-being and also how best to design interventions and research. Section 3 provides examples of current approaches. This book is an ideal resource for both researchers and advanced students interested in designing future-proofed research, for policy makers interested in improving community well-being and for practitioners interested in best practice applications.
