In today's lecture, we will 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 benefits are not uniform across all age groups. For instance, children tend to benefit more from active play areas, while older adults report greater improvements in mood from quiet, shaded walking paths. Interestingly, the research also indicates that the proximity of green spaces to residential areas matters more than their total size. A small park within a five-minute walk can have a stronger positive effect than a large park located far away. Therefore, city planners should prioritize creating accessible, small green pockets in densely populated neighborhoods.
