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.

According to the World Health Organization, 81% of teenagers are lacked in exercise. The result of the survey sounds reasonable. They may seem surprising, though.
Some of us think exercising is a waste of time when having many homework in high school. Others prefer phones to sports. Apart from these reasons, there is even some students who complain that they can’t afford sports facilities.
However, doing regular exercises can strengthen our body but make us energetic. It is also beneficial as it helped to remove pressure once in while. Therefore, my fellow friends, remember to stretch out ourselves every day at intervals of studies. More important, do stick with the workout.
As teenagers, we all expect for healthy bodies and a high quality of life. Let’s exercise together from then on!
4 . Pilates (普拉提), yoga and the running machine get all the attention when it comes to popular ways to keep fit. There is, however, a more humble exercise that might not be so attractive, but has all the benefits—walking.
Certified fitness professional Jolynn Jaekel explains, "What I love about walking is that anyone can do it at any age and any fitness level. Plus it is good for your heart, your head and your wallet.”
A recent report detailed the health benefits of walking. The report found that walking regularly to fulfill (执行,履行) the 150 minutes of moderate (适度的) physical exercise every week, recommended by the UK's chief medical officer, could save 37, 000 lives each year.
Scientists at Lawrence Berkeley National Laboratory in California found that quick walking reduced the risk of heart disease more effectively than running. They observed participants aged between 18 and 80 over a six-year period and found that walking reduced the risk of heart disease by 9.3%, while running reduced it by 4. 5%. And there is even more good news: 30 minutes of quick walking over five days could help you sleep easily, according to research by Oregon State University. The study by the university showed that walking helped participants sleep better and feel more alert during the day.
The sooner you get started, the sooner you'll notice the differences in your mind and body. So, go out for your 30-minute walk in a nearby park or green space.
