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 living within 300 meters of a park reported 20% lower stress levels. Interestingly, the effect was stronger for older adults, especially those over 65. However, the study also found that simply having a balcony with plants did not produce the same benefit. The key factor was direct access to a large, open green area where people could walk or sit quietly. So, for city planners, it's not just about planting trees, but designing spaces that encourage regular use.
