Today we're going to discuss the impact of urban green spaces on mental health. A recent study followed 1,000 adults over two years. Participants who visited parks at least once a week reported 20% lower stress levels. Interestingly, the size of the park mattered less than the frequency of visits. Also, those who engaged in group activities, like gardening clubs, showed even greater benefits. However, the study noted that access to green spaces in low-income areas remains limited, which is a key concern for policymakers.
