Good morning, everyone. Today we'll discuss the impact of urban green spaces on mental health. Recent studies show that access to parks and gardens can reduce stress levels significantly. For example, a study in Tokyo found that people who spent at least 30 minutes in a park three times a week reported lower cortisol levels. However, the benefits depend on the quality of the space, not just its size. A well-maintained garden with diverse plants and seating areas tends to have a stronger positive effect than a large but barren lawn. Interestingly, even viewing nature through windows can improve mood, though not as effectively as direct contact.
