Good morning, everyone. Today we're going to discuss the impact of urban green spaces on mental health. A recent study conducted in Melbourne followed over 2,000 adults for five years. Researchers found that people living within 300 meters of a park or garden reported significantly lower levels of stress and anxiety. Interestingly, the size of the green space mattered less than its accessibility. Even small community gardens had a positive effect if they were within a five-minute walk. However, the study also noted that the benefits were stronger for older participants, particularly those over 65, who showed a 22% reduction in symptoms of depression. Now, let's consider how these findings could influence city planning.
