In today's lecture, we're discussing the impact of urban green spaces on mental health. A recent study followed 1,000 adults over five years. Participants who visited parks or gardens at least three times a week reported 30% lower stress levels compared to those who rarely went outdoors. Interestingly, the size of the green space mattered less than the frequency of visits. Even small community gardens showed significant benefits. However, the study noted that access alone wasn't enough; people needed to feel safe and comfortable in these areas. So, city planners should focus not only on creating more parks but also on improving lighting and pathways to encourage regular use.
