Good morning. Today we're going to discuss the impact of urban green spaces on mental health. A recent study conducted in Melbourne followed 2,000 residents over five years. The researchers found that people living within 300 meters of a park or garden reported 20% lower levels of stress and anxiety. Interestingly, the size of the green space mattered less than its accessibility and the presence of trees. The study also noted that even small community gardens had a significant positive effect, especially for elderly residents. However, the researchers emphasized that these benefits were only observed when the spaces were well-maintained and safe to use.
