Good morning. Today we're going to discuss the impact of urban green spaces on mental health. A recent study conducted in Melbourne followed 1,000 residents over 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 pocket parks had a positive effect if they were easy to reach on foot. The study also noted that the benefits were stronger for younger adults, aged 18 to 35, than for older participants. However, the researchers cautioned that the study was observational, not experimental, so they couldn't prove causation directly.
