Good morning, class. Today we're going to 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 key factor isn't just the size of the space, but its accessibility. For example, a small community garden within a five-minute walk has a greater positive effect than a large park that requires a car trip. Additionally, the presence of water features, like ponds or fountains, appears to enhance the calming effect. Interestingly, the study also found that people who actively participate in gardening, rather than just visiting, experience even greater mental health benefits.
