Good morning. Today we're going to discuss the impact of urban green spaces on mental health. A recent study from the University of Melbourne followed 2,000 adults over five years. Participants who moved to neighborhoods with more parks and trees reported a 15% reduction in stress levels. Interestingly, the effect was stronger for people over 50. However, the study also found that simply having a balcony with plants had no significant benefit. The researchers suggest that the key factor is direct interaction with nature, such as walking or gardening, rather than just visual access. So, for city planners, it's not enough to add green areas; they must be designed to encourage active use.
