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 residents for five years. Interestingly, the researchers found that people living within 300 meters of a park or garden reported significantly lower levels of stress and anxiety. However, the effect was only noticeable for green areas with trees, not just grass lawns. The study also noted that the benefits were stronger for older adults and those who visited the space at least once a week.
