Healthy Habits, Healthy Body
Feel tired lately? Has a doctor said he can’t find anything wrong with you? Perhaps he sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong with you.
Then, consider this: you might be in a state of subhealth(亚健康).
Subhealth, also called the third state or gray state, is explained as a borderline state between health and disease.
According to the investigation by the National Health Organization, over 45 percent of subhealthy people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam-weeks.
Symptoms include a lack of energy, depression, slow reactions, insomnia(失眠), agitation(兴奋), and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs.
The key to preventing and recovering from subhealth, according to some medical experts, is to form good living habits, alternate work and rest, exercise regularly, and take part in open air activities.
As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables, fruit and fish because they are rich in nutritional elements — vitamins and trace elements that are important to the body.
Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract(消化系统). They also say that a balanced diet is very helpful in avoiding subhealth.

【推荐1】Is there any such thing as a salt tooth? We are familiar with a sweet tooth, along with the negative effects of sugar. We are broadly aware of the disadvantages of too much salt, including high blood pressure, which puts pressure on the blood vessels (血管), the heart and the kidneys. It can also lead to water retention (水肿). But we don’t tend to police how much salt we eat — at least, not as rigorously as with sugar — or question whether we are just paying attention to our bodies, which require some salt for muscles to work properly, or we are being controlled by a strong urge.
A salt tooth is quite unlike a sweet tooth. It doesn’t create an appetite for itself at the hormone level. But salt does make our taste buds (味蕾) get used to it, so that the more you eat, the more you need to get the same salty hit. This is why chefs can get heavy-handed with it.
As Sam Bloom, a nutritional therapist, explains, “What is generally more concerning is the fat that is used together with salt, like salty crisps, fries and fast food. Ready meals are often the worst for hidden salts. Anything that adds flavor that isn’t a spice or herb will probably have salt added to it and can make you want to eat more because it tastes good. The salt and fat combination in these foods is what causes problems with cholesterol (胆固醇). The salt that people add to a meal is much less concerning.”
Nutritionists’ suggestion is convincing: When the desire for salt hits, avoid going straight for salty snack foods such as crisps and instead ensure you are well hydrated. Seek out whole foods, such as olives and leafy greens. These foods will help you alleviate the desire for salt, which may often be due to a desire for nutrient-rich food.

【推荐2】Many adults rely on caffeine to get them through the day. But that’s the last thing kids need, according to the governments of England and South Korea.
England woke up to the news that the government is preparing to ban the sale of energy drinks like Red Bull to children.
The ban only applies to England, but Scotland, Wales and Northern Ireland can all follow suit if their administrations wish. In March, several major supermarket chains announced they would ban the sale of energy drinks to children under 16. Meanwhile, South Korea announced plans to ban the sale of coffee in schools by September 14.
The first reason for the ban is the high level of caffeine in the energy drinks, which has been linked to health problems for children, including head and stomach aches, as well as sleep problems.
A 250ml can of Red Bull contains about 80mg of caffeine, roughly the same as a similarly sized cup of coffee, but three times the level of CocaCola.Monster Energy, which is often sold in larger cans of 500ml, contains 160mg of caffeine.
Energy drinks often also have higher levels of sugar than soft drinks.Sugared energy drinks have 60% more calories and 65% more sugar than normal soft drinks and sugar is one of the largest causes of obesity.
British national official for education, Darren Northcott, described the drinks as “legal highs” that helped to fuel bad behavior in schools.
In addition to limiting kids’ access to caffeine and energy drinks, the South Korean government has also banned TV commercials for fast food, sugary snacks and highcaffeine beverages during times when most children’ s programs air.
South Koreans drink an average of 181 cups of coffee a year, by far the most in Asia.That is more than the 151 consumed per person in the UK but less than the average of 266 cups in the US.

There aren’t many believable numbers, but we do know the number of people who eat while sitting in front of some type of screen is growing. A recent study found that 33 percent of families always have the TV on during meal times and another 27 percent people have it on at least half the time. Another 10 percent may be texting, emailing or talking on a cell phone while eating.
Any type of these behaviors is bad, considering the following evidence:
A Canadian study found that children who watch more than three hours of cartoons a day are 50 percent more likely to be fat than children who watch fewer than two hours. The researchers concluded that more than 60 percent of overweight incidents can be connected with screen watching too much.
A three-week study found that adults who usually play with smartphones less burned 119 more calories per day.
One Chicago researcher found that people eat more potato chips while reading online than when they have the laptop turned off.
There has been very little investigation(调查) into eating with your eyes staring at a screen or reading a book, but it is likely that his mindless eating is related to weight gain. Simply speaking, your brain has no idea what is going on with your mouth because it is occupied by other things. You don’t notice how full your stomach is, and you often don’t even notice the taste or the act of chewing and swallowing, as a result of which, developing an adapted dietary habit is a must.

【推荐1】When temperatures rise, many people swim to beat the heat. But swimming does a lot more than that. It is a great workout for the whole body. Health experts at the University of California, Berkeley state that swimming is a great way to stay in shape.
Swimming is a very good high-intensity cardio exercise (高度有氧运动). Cardio involves the heart, lungs, and circulatory(血液循环的) system. The Berkeley experts say swimming can increase your heart rate and exercise your lungs. Some high-intensity cardio exercises, such as running, can improve your health but can also be likely to hurt your body. Swimming, on the other hand, is beneficial to the body and people often use it to recover from injuries.
Paul Waas, a coach and former competitive swimmer, says that swimming is more beneficial to the body than other sports because it is low-impact. A mother called Paloma with two daughters says that for her girls, swimming has been more beneficial to the body than some other sports. She said, “So far, I think it’s been good for their bodies. It’s a high-intensity cardio exercise, as you know. But it spares their knees, their joints, and so on. So it’s rare to get injured in swimming.”
The coach adds that swimming is a great exercise for kids who grow a lot in a short amount of time. Coach Waas said, “Swimming is really good for kids who are growing fast. Their bones might be hurting and they’re suffering from serious pain all the time. And then they get in the pool and, you know, they can float and stretch out a little bit and it reduces that as well.”
People who are overweight can also find relief through swimming. Their weightlessness in the water can help them to avoid injury as they exercise.

【推荐2】The latest sports craze is not even a sport. According to a recent article, “e-sports” are attracting a large number of audience.
In e-sports, players and teams compete in popular video computer games such as Dota 2 and Ovenvatch. Fans fill arenas to watch the action live on huge television screens.
The games have gone way past kids playing against each other while sitting on a sofa at home. The International, a major competition for players of Dota 2, awarded $24 million in prizes, with the winner taking home almost $11 million. A recent e-sports competition attracted more than 80,000 fans to the Olympic Stadium in Beijing, China.
I have to admit that I am not a big fan of computer games. I know that some games can be educational, but I think too many kids spend too much time sitting in front of a screen shooting space aliens. I think it would be better if kids spent more time reading or playing real sports such as basketball, baseball and soccer.
And please don’t tell me that competitive gaming is real sport because it requires hand-eye coordination. According to my American Heritage Dictionary, a sport is “an activity involving physical exertion and skill.” I don’t think anyone works up much of a sweat playing video games.
Too often, regular sports send kids a kind of message. Competition starts early, when lots of kids are not ready for the ups and downs of games. Tryouts and travel teams come next, giving too many kids the message they are “not good” at sports. So lots of kids quit sports and start playing more video games.
Maybe everyone in youth sports, including coaches, parents and kids, should think more about the advantages of real sports.

【推荐3】Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-km race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact（接触）with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories（卡路里）per hour, which is about twice as many as they would burn walking although fewer than running, which would probably burn about 1, 000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should Probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

【推荐1】The American space agency's Mars explorer, Perseverance, landed successfully on the Red Planet Thursday after a seven-month trip. The six-wheeled explorer, or rover, is on a NASA mission to collect Martian soil and rocks as part of the search for signs of ancient life. It took 11-and - one -half minutes for the confirmation signal to reach Earth. Moments later, controllers received the rover's first pictures of Mars.
Perseverance landed in an area of Mars called Jezero Crater, which contains a large ancient lakebed. NASA considers the area a promising place to find possible signs of microbial life (微生物). Scientists believe if life ever existed on Mars, it would have been present 3 to 4 billion years ago, when water flowed on the planet. However, rough ground around Jezero Crater presented possible landing dangers for the Perseverance spacecraft.
Perseverance is NASA's fifth rover to explore Mars. The first, named Sojourner, was sent in 1997. Then came Spirit and Opportunity, which landed in 2004. The fourth rover, Curiosity, has been exploring the planet since 2012. Those missions all resulted in valuable information about the Red Planet. NASA says Perseverance “aims to take the next step” in searching for signs of ancient microbial life.
It is NASA's largest, heaviest and most technology - loaded vehicle ever sent to Mars. It has 19 cameras, two microphones and a two- meter- long robotic arm. A machine connected to the arm will dig into the ground to gather rock and soil. The rover is equipped with X-ray and imaging systems to study Martian chemistry and to identify possible organic compounds (化合物). Perseverance is also carrying a small experimental flyer called Ingenuity. NASA says the 1. 8 kilogram vehicle will attempt its first flight in the coming months. NASA officials hope it will be the first vehicle to fly on a planet other than Earth.

【推荐2】The computer keyboard helped kill shorthand—a system of rapid handwriting, and now it’s threatening to finish off handwriting as a whole. When handwritten essays were introduced on the SAT exams for the class of 2012, just 15% of the most1.5 million students wrote their answers in cursive(手写体). The rest? Block letters.
And those college hopefuls are just the first edge of a wave of US students who no longer get much handwriting instructions in the primary grades, frequently 10 minutes a day or less. As a result, more and more students struggle to read and write cursive.
There are those who say the culture is at a crossing, turning from the written word to the typed one. If handwriting becomes a lost form of communication, does it matter?
It was at University Virginia that researchers recently discovered a previously unknown poem by Robert, written in his unique script. Handwritten documents are more valuable to researchers, historians say, because their authenticity can be confirmed. Students also find them more fascinating.
The loss of handwriting also may be a cognitive(认知的) opportunity missed. Several academic studies have found that good handwriting skills at a young age can help children express their thoughts better—a lifelong benefit.
It doesn’t take much to teach better handwriting skills. At some schools in Prince George’s County, elementary school students use a program called Handwriting Without Tears for 15 minutes a day. They learn the correct formation of manuscript (手写的)letters through second grade, and cursive letters in third grade.
1. A poem by Robert mentioned in the passage is used to ____________.| A．prove how valuable handwriting is | B．explain what a famous poet he is |
| C．show how unique his poem is | D．stress how fascinating the documents are |

【推荐3】The beauty of the outdoors naturally encourages people to go outside. The drive toward the natural world is present in normal times. Now, as many people are locked indoors, spending hours in front of screens, the pull of watching wind blow branches of neighboring trees is hardly matched. Forest therapy is one way to satisfy the demand while improving personal health and well-being.
Inspired by the Japanese practice of shinrin-yoku, or "forest bathing", forest therapy is a guided outdoor practice, which encourages people to experience the pleasures of nature through all of their senses and be present in the body.
Research on shinrin-yoku began in Japan in the 1980s when leaders there noticed a sharp rise in stress-related illnesses in the country, resulting from people spending more time working in technology and other industrial work. Specific settings were created to guide people in outdoor experiences. Research showed forest bathing may help reduce stress, improve attention, and lift moods.
Stress raises levels of cortisol, which plays a role in high blood pressure, heart disease and headaches. In test subjects, levels of cortisol decreased after a walk in the forest. Trees give off oils called phytoncides that have special properties and may influence immunity(免疫力). Exposure to natural tree oils helps lift depression, lower blood pressure. One study showed a rise in the number and activity of immune cells, which fight viruses and cancer, among people who spent three days and two nights in a forest compared with people taking an urban trip. This benefit lasted for more than a month after the forest trip!
Don't worry if you don't have three days to spend in the forest. A recent study showed spending at least 120 minutes a week in nature improved self-reported health and well-being. It doesn't matter whether the 120 minutes represents one long trip, or several shorter visits to nature. So, even as we are honoring physical distancing, it's possible and essential to get outside for 20 minutes every day and enhance our well-being.
