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 22% lower levels of stress and anxiety. Interestingly, the benefit was stronger for those who visited the space at least twice a week, regardless of the duration. However, the effect diminished for people living near busy roads, possibly due to noise and air pollution. The researchers concluded that proximity alone isn't enough; regular active use is key.
