In today's lecture, we'll discuss the impact of urban green spaces on mental health. A recent study conducted in Melbourne followed 1,000 residents over five years. Participants who lived within 300 meters of a park reported 20% lower stress levels. Interestingly, the type of greenery mattered: tree-covered areas had a stronger effect than open grass fields. The study also found that community gardens, though smaller, promoted social interaction, which indirectly boosted well-being. However, researchers noted that access alone isn't enough; the quality and maintenance of these spaces are crucial. So, for city planners, creating safe, well-maintained parks is more effective than simply increasing their number.
