Today we're discussing the impact of urban green spaces on mental health. A recent study followed 1,000 residents over five years. Participants who visited parks at least three times a week reported a 22% lower risk of depression. Interestingly, the size of the green space mattered less than the frequency of visits. Even small community gardens had positive effects. However, the study noted that access alone wasn't enough; social interaction in these spaces, like group gardening, amplified the benefits. So, while planting more trees is helpful, designing spaces that encourage community engagement is crucial.
