Today we're discussing the impact of urban green spaces on mental health. A recent study in Melbourne followed 1,000 residents over five years. Those living within 300 meters of a park reported 20% lower stress levels. Interestingly, the size of the green space mattered less than its accessibility. Small pocket parks with benches and walking paths were equally effective as large botanical gardens. However, the study noted that the benefits diminished when parks were overcrowded or poorly maintained. So, city planners should prioritize quality and convenience over sheer size.
