1 . You may be surprised to learn that one of the best steps you can take to protect your health is to step outside and spend some time in the grass, dirt and water. Our ancestors enjoyed the healing power of nature, and now scientists are starting to catch up. Researchers have documented how contact with nature can decrease mental tiredness, and enhance moods, concentration and problem-solving. Just having a view of nature has been shown to improve hospital patients’ recovery and reduce illness rates. Exposure to the open air, horseback riding, hiking, camping can be helpful for a variety of health conditions in adults and children. Much of this type of research is focusing on children, and in fact an entire movement has quickly developed to connect kids with the healing power of nature.

Obesity. Rates of childhood, adult obesity and related conditions including diabetes (糖尿病) and heart disease have grown greatly in recent years, partly because of reducing the time of outdoor activities. This problem can be partly addressed by increasing the time students spend learning about nature, both in and outside the classroom. Such lessons are often more engaging to students and often lead them to become more active outside.

Attention deficit hyperactivity disorder (ADHD) (注意力缺失症). An exposure to ordinary natural settings in the course of common after-school and weekend activities may be widely effective in reducing attention shortness symptoms (症状) in children. Participation in green activities helps ADHD patients keep focused and complete tasks.

Stress. Access to nature, even houseplants, can help children deal with stress.

Depression and seasonal emotional disorder. Major depression requires medical treatment, but physical activity, especially those done outdoors, can help ease symptoms. Staying in the sunshine for just a few minutes can also help supply bone-building vitamin D. Experts say that simply walking in a city park can enjoy nature’s benefits.

3 . The World Health Organization (WHO) says that 80% of the world’s teens don’t get enough exercise to live healthy lives. The report, published in The Lancet, was based on research done with students aged 11 to 17 in 146 different countries. The WHO has been studying teen activity levels since 2001.       1    

Doctors say 60 minutes’ daily exercise is needed for teens to build up their bone and muscle strength.       2       Regular activity can help them control their weight, too. Besides, more and more research is showing that exercise doesn’t just help the body, but also the brain, improving thinking, test scores, and school grades.

    3       They were also very different between boys and girls. In the US, for example, 64% of boys were not active enough, compared to 80% of girls. ROK (Republic of Korea) was the country with the lowest activity levels   — 91% of the boys and 97% of the girls didn’t get enough exercise.

One big reason for the lack of activity in today’s teens is technology, such as smartphones, computers and TVs.       4       The pattern of inactivity can severely affect their growth.

The WHO warns that teens need to do less playing in the digital world, and more playing in the real world. Teens should take part in sports, whether on official teams or just playing around on the playground. Exercise can also be built into a normal day’s activities.       5       Building such a habit now has positive effects on teens’ life.

C．Everyday workout also benefits them academically.

D．However, not much is reported to have changed since then.
