Today we're discussing 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. Interestingly, the effect was strongest for those who exercised there, not just sat. However, the researchers noted that the quality of the space mattered more than its size. Small, well-maintained community gardens had a greater benefit than large, neglected parks.
