In today's lecture, we'll discuss the impact of urban green spaces on mental health. Recent studies show that access to parks and gardens can reduce stress levels significantly. However, the benefits are not just limited to relaxation. Researchers found that people living near green areas tend to have better concentration and memory. Interestingly, the effect is stronger for older adults than for younger ones. Also, the size of the green space matters: small community gardens may have a greater positive influence than large, distant parks, because they encourage frequent visits. So, urban planners should prioritize creating small, accessible green pockets rather than relying solely on big parks.
