Lecturer: Today we're discussing the impact of urban green spaces on mental health. A recent study followed 1,000 adults over five years. Participants who lived within 300 meters of a park or garden reported 20% lower stress levels. Interestingly, the benefit was stronger for those who visited the space at least twice a week, regardless of its size. However, the study found no significant effect on physical health outcomes like blood pressure. Instead, the main gains were in mood improvement and reduced anxiety. The researchers suggest that even small, well-maintained green areas can be effective, but they emphasize that accessibility, not just proximity, matters most.
