Good morning, everyone. Today we'll discuss the impact of urban green spaces on mental health. A recent study from the University of Melbourne followed 500 adults for five years. Participants who lived within 300 meters of a park reported 20% lower stress levels. Interestingly, the size of the park mattered less than the presence of trees. The study also found that people who visited green spaces at least three times a week showed better concentration and memory. However, the researchers noted that benefits were strongest in older adults, not young people as previously assumed.
