Today we're going to discuss the impact of urban green spaces on mental health. A recent study followed 1,000 residents over two years, measuring their stress levels and mood. Interestingly, the participants who visited parks at least three times a week reported a 20% reduction in anxiety symptoms, compared to those who rarely went outdoors. However, the benefit was only significant when the green space was within a 10-minute walk from home. Also, the study found that community gardens had a stronger effect than passive parks, because they encouraged social interaction and physical activity. So, it's not just about having trees, but how people engage with the space.
