Today's lecture focuses on the impact of urban green spaces on mental health. Recent studies have shown that access to parks and community gardens can significantly reduce stress levels. However, the research also highlights that the size of the green area matters less than its accessibility and quality. For instance, a small, well-maintained garden near residential buildings often has greater benefits than a large, distant park. Additionally, the presence of water features, such as ponds or fountains, appears to enhance the calming effect. Interestingly, the study found that even viewing green spaces from a window can improve mood, but direct interaction is most effective.
