Today we're going to discuss the impact of urban green spaces on mental health. A recent study conducted in Melbourne followed 3,000 residents over five years. Participants who lived within 300 meters of a park reported lower stress levels. Interestingly, the effect was stronger for people over 50. The study also found that having trees, not just grass, increased the benefit by 20%. However, access alone wasn't enough; regular visits, at least once a week, were crucial. The researchers suggest city planners prioritize small, nearby green areas over large distant parks.
