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. Interestingly, participants living within 300 meters of a park reported 15% lower stress levels. However, the benefit was only significant for those who visited the space at least once a week. The study also found that the type of vegetation mattered: areas with diverse tree species had a stronger positive effect than simple grass lawns. So, it's not just about having a green area, but its quality and accessibility.
