Today we're discussing the impact of urban green spaces on mental health. A recent study followed 1,000 residents over five years. Participants who visited parks at least twice a week reported 40% lower stress levels. Interestingly, the size of the park didn't matter, but the presence of water features, like ponds or fountains, had a significant positive effect. The study also found that people who exercised in green spaces, rather than just sitting, showed greater improvements in mood. However, the benefits diminished for those living more than a 10-minute walk from the nearest green area.
