Good morning, everyone. Today we're going to discuss the impact of urban green spaces on mental health. A recent study from the University of Melbourne followed 2,000 adults over five years. Participants who lived within 300 meters of a park reported 15% lower levels of stress hormones. Interestingly, the size of the green space mattered less than its accessibility. Even small pocket parks with benches and trees had positive effects if they were easy to reach on foot. However, the study also found that simply having a view of trees from a window did not significantly reduce stress, suggesting that physical interaction with nature is key.
