Good morning, everyone. 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. Surprisingly, the researchers found that the presence of trees, rather than parks or lawns, had the strongest positive effect on reducing stress levels. They also noted that the benefits were more pronounced for people who lived within 300 meters of green areas, and that the effect was stronger in women than in men. However, the study did not find a significant link between green spaces and improved physical health, such as lower blood pressure.
❓ According to the lecture, which factor had the most significant positive impact on reducing stress?
