Today's lecture focuses on the impact of urban green spaces on mental health. Recent studies have shown that access to parks and gardens can reduce stress levels by up to 20%. However, the key factor is not just the presence of greenery, but its quality and accessibility. For instance, well-maintained parks with seating areas and walking paths encourage more frequent visits. Interestingly, the research also found that even small rooftop gardens in dense city centers can provide significant benefits, especially for office workers who lack ground-level access. The lecturer emphasizes that city planners should prioritize creating interconnected green networks rather than isolated pockets of nature.
