Today we're going to discuss 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 or garden reported 20% lower stress levels. Interestingly, the effect was stronger for people who visited these spaces at least twice a week, even for short periods. However, the study found no significant difference between small pocket parks and larger recreational areas. The key factor seemed to be the presence of trees and natural vegetation, not the overall size. So, for city planners, it's more about quality than quantity.
