Lifestyles are increasingly characterised by sedentary behaviour, obesity problems, stress, mental ill-health and disconnection from nature. However, contact with nature has been shown to improve psychological health by reducing stress, enhancing mood and replenishing mental fatigue. In addition to providing a range of environmental services, green spaces provide opportunities and incentives for ‘green exercise’ such as walking, cycling or horse riding. Visitor numbers indicate that many people already benefit from spending time in green spaces, but little is known about the immediate impact of acute exposure on their health and wellbeing. This study focuses on evaluating changes in self-esteem and mood after walking in four different National Trust sites of natural and heritage value in the East of England. The standardised measures of both self-esteem and mood were administered immediately pre- and post-activity. Self-esteem scores for visitors leaving the sites were significantly higher than those just arriving and overall mood also significantly improved. Feelings of anger, depression, tension and confusion all significantly reduced and vigour increased. Thus, the environment plays an important role in facilitating physical activities and helping to address sedentary behaviours. Walking, in particular, can serve many purposes including exercise, recreation, travel, companionship, relaxation and restoration. However, walking in greenspaces may offer a more sustainable option, as the primary reward is enhanced emotional wellbeing through both exposures to nature and participation in exercise.
