Today we're going to discuss 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 lived within 300 meters of a park reported 20% lower stress levels. Interestingly, the type of vegetation mattered: areas with diverse tree species had a stronger positive effect than those with only grass. The study also found that simply viewing green spaces from a window improved mood, but physical activity in these spaces gave the greatest benefit. So, city planners should prioritize not just adding parks, but ensuring biodiversity.
