Professor: Today we're discussing the impact of urban green spaces on mental health. A recent study followed 1,000 residents over five years. Those who lived within 300 meters of a park reported 20% lower stress levels. Interestingly, the size of the park mattered less than the frequency of visits. Even small gardens, if visited daily, had significant benefits. However, the study also found that residents who only viewed greenery from their windows, without direct access, showed no improvement. So, it's not just seeing nature, but interacting with it that counts.
