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 key factor isn't just the size of the green area, but its accessibility. For instance, a small community garden within a five-minute walk from home is more beneficial than a large park that requires a long commute. Additionally, the presence of water features, like ponds or fountains, enhances the calming effect. Interestingly, the study also found that people who engage in gardening activities report higher life satisfaction than those who merely visit parks.
