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 once a week reported 20% lower stress levels compared to those who didn't. Interestingly, the size of the green space mattered more than the frequency of visits. Small pocket parks had minimal effect, while large tree-covered areas showed significant benefits. The researchers also noted that even brief exposure, like 10 minutes, could improve mood, but the effect lasted longer when people engaged in activities like walking or gardening.
