In today's lecture, we'll discuss the impact of urban green spaces on mental health. A recent study from the University of Cardiff followed 1,000 adults over five years. Participants who visited parks or gardens at least twice a week reported 20% lower stress levels compared to those who didn't. Interestingly, the duration of each visit mattered less than the frequency. Even short visits of 15 minutes were beneficial. The researchers also noted that the effect was stronger for people living in densely populated areas. So, for city planners, creating small, accessible green pockets may be more effective than a few large parks.
