CET-4 Listening Practice: Why a Walk in Nature Helps

For many university students, a typical day is spent almost entirely indoors. They move from the dormitory to the classroom, and then on to the library. In the evening, most of their free time is spent looking at screens. At the same time, a growing number of students say they feel anxious and under pressure. Many of them go over the same worries again and again, especially before exams. So, can a simple walk in nature really make a difference? A study carried out at Stanford University in twenty fifteen suggests that it can. Researchers asked thirty-eight healthy adults from the city to go for a ninety-minute walk. Half of the participants walked through a quiet green area near the campus. The other half walked along a busy road with heavy traffic. Before and after the walk, each person answered questions about their negative thinking. They also had their brains scanned. According to the results, the nature group spent less time on negative thoughts. In addition, an area of the brain linked to this kind of thinking became less active. However, the people who walked beside the traffic showed no such change. In other words, time in nature seems to give a busy mind a rest. The researchers pointed out that people living in cities face a higher risk of mental health problems. For this reason, green spaces may play an important role in protecting our mental health. Worrying too much makes it hard to concentrate, and as a result, our studies suffer. The good news is that you don't need to climb a mountain to benefit. Even a short walk in a park or along a river can help. Try to leave your phone in your bag and cut down on screen time. Some students feel that a walk before an exam is a waste of time. In fact, a break outdoors may help you return to your books with a clearer mind. So why not make a habit of walking outside two or three times a week? In the long run, your mind and your grades may thank you for it.
