2 . Obesity (肥胖) has become a serious problem now. According to a recent survey, teenage obesity has increased at an alarming rate across America. Teenage obesity is mainly due to the increased consumption (消耗) of junk food which contains large amounts of fat. This has exposed the teens to a 14% greater risk of having a heart attack as well as seriously high blood pressure.

Various causes of teen obesity have been claimed, the most important of which is being insufficient (不足) physical exercise on the teen’s part. It is argued that teens nowadays who lack (缺少) sufficient physical exercise topped with their unhealthy eating habits are more likely to be obese. Nowadays, a main part of the teenagers spend their spare time on the computer, television or perhaps simply playing games. This greatly limits any kind of physical activity of the teenager. According to a recent survey, around 43% of teenagers spend more than 2 hours watching television every single day.

Long time inactivity in addition to the ill eating habits has increased the incidence (发生率) of obesity in teenagers even more, However, this does not mean that teens do not do enough exercise, but the amount which they do, is certainly not sufficient as compared to their intake of fatty foods. Besides this, parents need to change the whole lifestyle of the family in order to develop a healthier lifestyle of their children.

The teenagers must also be encouraged to take part in other physical activities which require more effort; such as playing basketball, tennis, badminton, volleyball and swimming. Meanwhile, the teenagers also need to be educated on the ill effects of junk food and must be asked to avoid them as much as possible. Their diet must also be made healthier and more balanced, which will help them in losing more weight quickly. For better guidance on reducing the teen’s weight quickly, parents can always turn to a doctor.

8 . Much of our thinking about health is based on wishful thinking. But science provides clear and simple advice for a healthy life. Graham Lawton explores the evidence. Graham proves that you don’t have to be a health and fitness extremist to be reasonably healthy. He has rounded up the latest and strictest health research and changed it into useful advice on all the big health questions: diet, weight loss, exercise, sleep, ageing and so on.

Graham, New Scientist feature writer, is not the common health expert. He sometimes eats fast food. He has a gym membership but rarely uses it. And he takes medicine to keep his blood pressure under control. He neither has a diet plan nor a 6-week program to keep fit and thin.

But he does have a much better weapon: science. In a talk, Graham explains the basic science, tells people some of the secrets of science, teaches people to use the ability of judgement to tell the good from the bad, and helps them to see beyond the headlines. The talk allows people to eat healthily, lose weight, and sort the truth out from science facts.

But he loves outdoor sports. Last year Graham cycled over 1,200 miles and ran the same distance of 15marathons. He often goes swimming outdoors and walks up eight flights of stairs to his desk instead of taking the lift. He eats his five copies of fruit and vegetables a day, keeps enough water in his body, and doesn’t eat much meat. Despite all the bad habits, his good ones seem to be winning. Graham is 50, but his “biological age” was recently measured as 45.

9 . Most people think that regular (有规律的) exercise does health wonders for people, but what exactly are its health benefits (益处)?

To start with, research suggests regular exercise can help make people’s body strong. It helps cut down on the number of different diseases people face each year. Regular exercise throughout the year helps the working quality of people’s heart become better and lower blood pressure. During exercise, people’s heart must work harder so that it can make blood go throughout the body. This extra effort makes it grow stronger over the long term. At the same time, as little as 30 minutes per day can help to lower blood pressure. It helps move away things that are all linked to having high blood pressure.

Exercise has a good effect on people’s mind and spirit too. If you are suffering from stress and sadness, regular gentle exercise is one way to improve your full sense of happiness. The way that exercise improves people’s mental state is by moving away the bad effect of stress that swims into their bodies, helping them find deep calm.

Some studies even show that exercise keeps people’s skin fit. Exercise helps keep skin cells alive and healthy by increasing blood flow. Blood carries oxygen and nutrients to working cells throughout the body, including the skin. In addition to providing oxygen, blood flow also helps carry away waste products. You can think of it just like cleaning your skin from the inside.

However, we should know that when suffering from an illness, try not to finish all your plan for exercise. The body needs time to recover. Strong exercise can be harmful to the immune system (免疫系统) when it is already under pressure. Instead, take a gentle walk when falling ill to help recovery.
