Today's lecture focuses on the impact of urban green spaces on mental health. Recent studies show that access to parks and gardens can reduce stress levels by up to 20%. However, the key factor is not just the presence of green areas, but their accessibility within a 10-minute walk from home. Surprisingly, the quality of the space matters more than its size. For instance, small but well-maintained community gardens with seating and shade have a greater positive effect than large, empty lawns. Additionally, residents who actively participate in gardening report higher life satisfaction compared to those who merely visit parks.
