Good morning, class. Today we're discussing the impact of urban green spaces on mental health. A recent study from the University of Melbourne followed 1,000 residents over five years. Participants who visited parks at least twice a week reported 30% lower stress levels. Interestingly, the size of the park mattered less than the presence of water features, such as ponds or fountains. The researchers also noted that community gardens had a stronger social benefit than large lawns. However, the study's limitation was that it relied on self-reported data, not clinical measures.
