In today's lecture, we'll discuss the impact of urban green spaces on mental health. A recent study followed 500 adults over two years, tracking their daily exposure to parks and gardens. The results showed that people who spent at least 30 minutes per day in green areas reported 20% lower stress levels. However, the key factor was not the total time but the frequency of visits. Those who visited short periods five times a week benefited more than those who stayed longer once a week. Interestingly, the type of green space mattered too: tree-lined streets had a stronger effect than open lawns, likely due to the sense of enclosure and biodiversity.
