Connecting through nature: A systematic review of the effectiveness of nature-based social prescribing practices to combat loneliness

We reviewed 38 articles on how nature-based group interventions affect loneliness. Quantitative studies had small sample sizes and small or moderate effects. Qualitative studies showed more clearly how these interventions reduce loneliness. Group-based activities including natural elements cultivate connectedness and belonging. Longer interventions showed greater promise in reducing loneliness. Linking landscape with public health promotes and amplifies the value of urban nature.
