The concept of Green Exercise (GE) has now been widely adopted and implies a synergistic health benefit of being active in the presence of nature. This book aims to provide a balanced overview and synthesis text on all aspects of GE and integrate evidence from many different disciplines including physiology, psychology, sociology and the environmental sciences. "Physical activity promotes health. Nature contact promotes health. This wonderful book explores the intersection of the two, providing both theory and evidence, across cultures, on the benefits of green exercise. It's timely, thorough, and readable - the definitive source on green exercise.Highly recommended." - Howard Frumkin, School of Public Health, University of Washington, USA. "Green Exercise provides an antidote for much of what ails modern society. This book will help both to protect the natural world and to enhance public health. Evidence presented in this book- regarding beneficial effects of green exercise on myriad outcomes including physical activity, obesity, attention, mental health, and immune function- can be leveraged in support of policies to protect woodlands, programs to facilitate active engagement with the natural environment, interventions to reduce health disparities, and to inspire each of us to be active outdoors." - Nancy M. Wells, Designand Environmental Analysis, Cornell University, USA.
