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 1,200 adults over five years. Participants who visited parks or gardens at least twice a week reported 20% lower stress levels and improved sleep quality. Interestingly, the benefits were stronger for those who engaged in activities like gardening or walking, rather than just sitting. The study also found that the positive effect was most noticeable in people aged 40 to 60, not in younger adults. However, researchers noted that access to green spaces in densely populated areas remains limited, so they recommend designing more rooftop gardens and community plots.
