小溪的潺潺水聲，樹葉被風(fēng)吹動(dòng)的沙沙響聲，這些大自然的聲音給予我們的感官體驗(yàn)完全不同于城市里人潮、車流的嘈雜聲。 親近自然能夠使大腦得到放松，改善人們的精神狀態(tài)。

When you go to the desert with David Strayer, don't be surprised if he sticks electrodes(電極) to your head. As a cognitive psychologist at the University of Utah, Strayer studies the mind's ability to think clearly.

On the third day of a camping trip in Utah,Strayer is explaining the “three-day effect” to 22 psychology students. Our brains, he says, aren't tireless three-pound machines; they are easily exhausted by our fast-paced and increasingly digital lives. But when we slow down, stop the busywork, and seek out natural surroundings, we not only feel restored but also improve our mental performance. Strayer has proved with a group of participants, who scored 50 percent higher on creative problem-solving tasks after three days of wilderness backpacking.

Researchers from the University of Exeter Medical School analyzed data from 10,000 urban citizens and found that those living near more green space reported less mental disease.Richard Mitchell, a geographer at the University of Glasgow, found fewer deaths and less disease in people who lived near green space, even if they didn't use them. People who have window views of trees and grass have been shown to recover faster in hospitals, perform better in school, and show less violent behavior.

In some countries, nature is involved in the government's official mental health policy. At the Natural Resources Institute Finland, the nation's high rates of alcoholism and suicide led a research team to recommend that citizens spend at least five hours per month being close to nature in an effort to improve the nation's mental health. “A 40-50 minutes walk seems to be enough for physiological changes and mood changes,” says Kalevi Korpela, a professor of psychology.
