The Contribution of natural environment related activies to reducing stress among visitors: a study related To Diyasaru Wetland Park, Sri Lanka

Abstract

Urbanization has led to a significant increase in stress and a decline in mental well-being among city residents. Urban wetland parks, such as Diyasaru Park, are increasingly recognized as vital restorative environments that can mitigate these negative effects. This research aims to evaluate the contribution of natural environment-related activities to stress reduction and emotional restoration among urban residents. The study is grounded in key environmental psychology theories, including Stress Reduction Theory (SRT), Attention Restoration Theory (ART) and Perceived Naturalness and Wilderness. Using a quantitative method, quasi-experimental design, the research will collect pre- and post-visit data using standardized questionnaires (PSS) and site observations. The findings are expected to demonstrate that exposure to and interaction with the park's features, particularly its hard landscape elements, significantly improves visitors' psychological well-being. The study's conclusion provide evidence-based recommendations for urban planners and park managers to enhance the restorative potential of urban green and blue spaces.
