Good morning, everyone. Today we're going to discuss the impact of urban green spaces on mental health. A recent study followed 2,000 adults over five years. Participants who lived within 300 meters of a park or garden reported 20% lower stress levels. Interestingly, the effect was stronger for those who visited the green space at least twice a week, regardless of its size. However, the study noted that noisy parks, near busy roads, had less benefit. So, it's not just about having green areas, but about their quality and accessibility.
❓ According to the lecture, what condition made urban green spaces less beneficial for mental health?
