Good morning, class. Today we'll discuss the impact of urban green spaces on mental health. A recent study followed 1,000 adults over five years. Participants who visited parks at least once a week reported 22% lower stress levels. Interestingly, the size of the park mattered less than the frequency of visits. Also, those who engaged in group activities, like community gardening, showed even greater improvements in mood. However, the study noted that access alone wasn't enough; the quality of the green space, including safety and maintenance, played a crucial role. So, for city planners, it's not just about adding more parks but ensuring they are inviting and well-kept.
