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 significantly reduce stress levels. However, the benefits are not just limited to relaxation. Researchers found that people living within 300 meters of a green area reported better sleep quality. Interestingly, the type of vegetation also matters. Dense tree cover was linked to lower noise pollution, while open lawns encouraged social interaction. The speaker emphasizes that city planners should prioritize maintenance over creation, as neglected green spaces can have negative effects.
