Today we're discussing the impact of urban green spaces on mental health. A recent study conducted in Melbourne followed 500 residents over five years. Participants who lived within 300 meters of a park or garden reported significantly lower stress levels. 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 found that people who visited these spaces at least once a week showed better emotional resilience. However, the researchers noted that simply having a view of greenery from a window did not produce the same benefits as physical presence. So, the key factor is regular, direct exposure.
