The effects of green space on college students’ mood

Abstract Objective: Less attention has been given to how green space can impact college students’ moods. This study aimed to examine whether university students exposed to outdoor and indoor green space-natural and artificial would experience a change in moods compared to students not exposed to green space. Method: Seventy-nine participants were randomly assigned to four different conditions: office without greenery, office with posters of nature, office with green plants, and outside in a garden. The Brunel Mood Scale was used to assess participants’ moods before and after spending time in their assigned setting. Results: Results indicated that all participants experienced a decline in tension and fatigue regardless of their assigned setting, yet the decline was less pronounced among participants in the office without greenery. Conclusion: Study findings highlight indoor green space is also conducive to positive moods. Thus, in addition to protecting outside greenery, universities may invest in indoor greenery (e.g., indoor plants, posters/artwork featuring nature) that can be placed in classrooms, libraries, dormitories, and other spaces frequented by students.Keywords: College studentsexperimentgreen spacemood AcknowledgmentsWe want to thank Dr. Josh Witten from the South Carolina Governor’s School for Science and Mathematics and Melissa Hawkins from the Clemson University Honors College for their support in this project.Conflict of interest disclosureThe authors have no conflicts of interest to report.
