Today we're going to discuss the impact of urban green spaces on mental health. A recent study conducted in Melbourne followed 1,000 residents over five years. The researchers found that people living within 300 meters of a park reported 20% lower stress levels. Interestingly, the type of green space mattered: tree-lined streets had a stronger effect than open lawns. The study also noted that even small gardens or balcony plants contributed to improved mood, but the effect was less significant. The lead author, Dr. Elena Rossi, emphasized that city planners should prioritize connecting existing parks with tree corridors.
