In today's lecture, we'll discuss the impact of urban green spaces on mental health. A recent study followed 1,000 residents over three years. Participants who visited parks at least once a week reported 20% lower stress levels compared to those who didn't. Interestingly, the size of the park mattered less than the frequency of visits. Even small community gardens showed significant benefits. However, the study noted that access alone wasn't enough; people needed to feel safe and have social connections in these spaces to gain full advantages. So, urban planners should focus on creating accessible, safe, and socially engaging green areas.
