Good morning, everyone. Today we're going to discuss the impact of urban green spaces on mental health. A recent study conducted in Melbourne followed over 2,000 adults for five years. The researchers found that people living within 300 meters of a park or garden reported significantly lower levels of stress and anxiety. Interestingly, the size of the green space mattered less than its accessibility. Even small community gardens had a positive effect, provided they were well-maintained and had seating areas. The study also noted that the benefits were stronger for older participants, especially those over 65, who used the spaces daily for walking or socializing.
