Physical Activity for Human and Planetary Health: Incorporating Green Exercise in the Management of Rheumatic Disease.

Rheumatic disease prevalence is increasing worldwide in conjunction with ever increasing detrimental effects of climate change on planetary health. Both physical inactivity and environmental exposures, such as air pollution, contribute to the development of immune dysfunction and subsequent development of rheumatic disease. Conversely, green exercise-physical activities performed in nature, including walking or cycling as active transport, and tree and garden planting-holds strong potential to improve health both for patients with inflammatory rheumatic disease and the planet.
