Good morning, everyone. 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 lived within 300 meters of a park reported 22% lower levels of stress and anxiety. Interestingly, the size of the green space mattered less than its accessibility. Even small gardens or tree-lined streets had positive effects. However, the benefits were strongest for people who visited these areas at least once a week. The researchers also noted that noise reduction and improved air quality were secondary factors, not the main cause of the mental health boost. So, what does this mean for city planning?
