Today's lecture focuses on the impact of urban green spaces on mental health. Research conducted in Melbourne followed 1,000 adults over five years. The study found that people living within 300 meters of a park reported 20% lower stress levels. However, the benefit was only significant for parks with trees and water features, not grassy areas alone. Interestingly, the effect was stronger for older participants, especially those over 65, who showed a 30% reduction in anxiety. The lecturer suggests that city planners should prioritize tree planting near residential zones.
