Good morning, everyone. Today we're discussing the impact of urban green spaces on mental health. A recent study followed 1,000 city dwellers over five years. Participants who visited parks at least once a week reported 22% lower levels of stress hormones. Interestingly, the size of the park mattered less than the frequency of visits. Even small community gardens showed benefits. However, the study noted that passive viewing of green spaces, like from a window, had no significant effect. So, it's not just seeing nature, but actively being in it that counts. Now, let's consider how city planners can apply these findings.
