Effects of School-led Greenspace Interventions on Mental, Physical and Social Wellbeing in Children and Adolescents: A Systematic Review

Promoting children’s and adolescents’ mental, physical, and social wellbeing is highly important to help them learn, create social connections, and stay healthy. Nature has the potential to restore cognition, reduce stress and mental fatigue, and improve wellbeing, all factors that are conducive to learning. There is growing interest in understanding the effects of nature on the wellbeing of children and adolescents, particularly in the school context. This paper presents a PRISMA-guided systematic review of the literature examining the effects of school-led nature interventions on the mental, physical, and social wellbeing of school children and adolescents aged 5 to 19 years. Examples of school-led nature interventions include outdoor learning, walks in nature and green schoolyards. Experimental and quasi-experimental studies employing quantitative measures were selected, yielding 19 studies from 17 papers. Included studies were rated as being of high (n = 6) and moderate quality (n = 13). The results provide some evidence that nature exposure in the school context can improve the wellbeing of children and adolescents, particularly their positive affect, physical activity, and social relationships/interactions. The wellbeing effects of school-led nature interventions were also examined according to age and gender, with results indicating a gender effect, but inconclusive findings for age. Findings from this review support the integration of nature in schools to enhance the mental, physical and social wellbeing of children and adolescents.
