Today we're going to discuss the impact of urban green spaces on mental health. A recent study followed 1,000 adults over five years. Participants who visited parks at least once a week reported 20% lower stress levels. Interestingly, the size of the park didn't matter, but the presence of water features did. Those near ponds or fountains showed the greatest improvement. The study also found that even brief visits of 10 minutes were beneficial. So, city planners should prioritize small, accessible green areas with water, rather than large distant parks.
