Good morning. Today we'll discuss how urban green spaces affect mental health. A recent study from the University of Melbourne followed 500 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 people who visited the space at least three times a week, regardless of the size of the green area. The lead researcher, Dr. Emily Chen, noted that even small community gardens can provide significant psychological benefits if used regularly. However, she emphasized that access alone is not enough; active engagement with nature is key.
