Today we're going to discuss the impact of urban green spaces on mental health. A recent study conducted in London followed over 1,000 residents for five years. Participants who lived within 300 meters of a park or garden reported 20% lower levels of stress and anxiety. Interestingly, the effect was stronger for older adults and those who visited the space at least twice a week. The study also noted that simply having a view of greenery from home had a small but measurable benefit. However, the researchers emphasized that the quality of the green space mattered more than its size, with well-maintained areas having a greater positive impact than larger, neglected ones.
