Good morning. 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 residents for five years. The researchers measured the amount of green space within one kilometer of each participant's home. They found that people living near parks or gardens reported significantly lower levels of stress and anxiety. Interestingly, the beneficial effect was strongest for middle-aged adults, not the elderly or young people. The study also noted that the quality of the green space mattered more than its size. A small well-maintained garden had a greater positive impact than a large neglected park.
