Good morning, class. Today we're going to discuss the impact of urban green spaces on mental health. A recent study conducted in Melbourne followed over 1,000 adults for five years. Researchers found that people living within 300 meters of a park or garden reported significantly lower levels of stress and anxiety. Interestingly, the effect was stronger for older participants, especially those over 65. However, the study also noted that simply having a balcony with plants did not produce the same benefit. The key factor seemed to be actual access to ground-level green areas where people could walk or sit. So, in future city planning, it's crucial to prioritize these accessible spaces.
