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 pocket parks had a positive effect if they were easy to reach on foot. The study also noted that the benefits were stronger for individuals over 50 years old, possibly due to their increased use of these areas for walking and socializing.
