Today we're discussing the impact of urban green spaces on mental health. A recent study from the University of Melbourne followed 500 office workers over two years. Participants who had a view of trees or parks from their windows reported 15% lower stress levels compared to those facing other buildings. Interestingly, the benefit was strongest for people who spent less than 30 minutes outdoors daily. The researchers suggest that even brief visual contact with nature can trigger a relaxation response. However, they note that the effect diminishes if the green area is poorly maintained or lacks biodiversity. So, the quality of the green space matters more than its size.
