In today's lecture, we'll discuss the impact of urban green spaces on mental health. Recent studies have shown that access to parks and gardens can significantly reduce stress levels. However, the size of the green area matters less than its accessibility. For example, small community gardens within walking distance of homes are more beneficial than large distant parks. Additionally, the presence of water features, like ponds or fountains, seems to enhance the calming effect. Interestingly, the study also found that people who visit green spaces at least three times per week report better emotional well-being, regardless of the duration of each visit.
