Good morning, everyone. Today we're going to discuss the impact of urban green spaces on mental health. Recent studies have shown that even small parks can reduce stress levels significantly. Interestingly, the research found that the presence of water features, like ponds or fountains, had a stronger calming effect than trees alone. However, the most surprising result was that people who visited these spaces for at least 30 minutes, three times a week, reported a 20% decrease in anxiety symptoms. This was regardless of whether they exercised or just sat quietly. So, it's not just about physical activity.
