Professor: Today we're discussing the impact of urban green spaces on mental health. A recent study followed 1,000 adults over five years. Participants who lived within 300 meters of a park reported 20% lower stress levels. Interestingly, the effect was stronger for those who visited the park at least twice a week, regardless of its size. However, the study found no significant difference between small gardens and large parks for daily mood improvement. The key factor seemed to be regular exposure, not the total area. So, for city planners, creating many small accessible green areas may be more effective than one large central park.
