Today we're discussing the impact of urban green spaces on mental health. A recent study followed 500 adults over two years, measuring their stress levels and time spent in parks. The results showed that people who visited green spaces at least three times a week reported 20% lower cortisol levels. Interestingly, the duration of each visit mattered less than the frequency. Even short visits of 10 minutes were effective. However, the study noted that the quality of the green space, such as presence of trees and quiet areas, played a significant role. Poorly maintained parks had no measurable benefit.
