Good morning. Today we're going to discuss the impact of urban green spaces on mental health. A recent study from the University of Melbourne followed 1,200 residents over a five-year period. Participants who lived within 500 meters of a park or garden reported 15% lower levels of stress hormones. Interestingly, the effect was stronger for people who visited the green space at least twice a week, regardless of the size of the area. The study also found that community gardens were more beneficial than ornamental parks, possibly because they encourage social interaction and physical activity.

A. A. People living near large ornamental parks
B. B. People who visited green spaces twice a week or more
C. C. People who lived more than 500 meters from a park
D. D. People who only exercised indoors
✅ 正确答案
