Today we're going to discuss the impact of urban green spaces on mental health. A recent study followed 1,000 residents over five years. Those who lived within 300 meters of a park reported 20% lower stress levels. Interestingly, the benefit was stronger for people who visited the park at least twice a week. However, the study found no significant difference between small gardens and large parks. The researchers suggest that even a small green area, if used regularly, can improve well-being. So, the key is not size, but frequency of use.
