【推荐2】Travel and illness go hand in hand. How many times have you been on the road or traveling by plane and within a three-day time the flu comes knocking?     1     Ways to prevent? Like all good things, there is a set list of ingredients to fight against getting sick while traveling is necessary.

Take your herbs(药草) with you.

By all means, you should pack some herbs.     2     This bitter fluid has been studied to show an improved immunity of a person who suffers from respiratory(呼吸道的) infections. a great herb to have on a hand (especially if you intend on trying a new restaurant) will help settle that upset digestive track.

Do not ignore symptoms.

    3     This alone can save several days spent in misery. However, sometimes we have to travel for business, so postponing is looked down upon. If, this is the case, check your insurance coverage when it comes to domestic and international traveling. This is a cautious move when it comes to needing medical assistance while traveling.

    4    

Walking around the city, running, or exercise of some sort will help fight off travel illnesses. We would all like to walk around for an entire week, but, be sure to clock in some exercises or low cardio action(有氧运动). Cardio helps our immunities to stay in shape and traveling can be a bit dangerous on that front. There’s a lot of waiting around, so take that little extra time to jog in place or run.

Pack vitamins.

This is an easy one to forget. As a last minute check, pack some vitamins you nearly take at home. Just because you’re traveling doesn’t mean you get a back seat to when it comes to the flu.     5    

【推荐1】The spiders have long, scary legs. Some spiders even bite. But Spider-Man is another story. He might help people see spiders less negatively, a new study finds.

After Menachem Ben-Ezra, a proud fan of the Marvel films and also a psychologist, saw the movie Ant-Man and the Wasp(黄蜂), he walked out with a sudden scientific idea that he should measure people before they went into the theater, and afterwards to see if the fear of ants would be reduced or changed.

Ben-Ezra and his colleagues asked 424 people questions, about one-quarter of them about spiders, such as “Did you find them scary?” “Did seeing one make your hearts race and palms sweat?” A second group received similar questions, this time about ants. The last two groups got the same questions about other insects. Afterward, everyone watched videos. Group one got a Spider-Man movie. Group two saw Ant-Man and the Wasp. Groups three and four watched unrelated video---wheat waving peacefully in the breeze.

After viewing the movie, Ben-Ezra again asked the participants how they felt about spiders, ants or other insects in general---and found the ant and spider exposures seemed to make people insensitive and less afraid. Between 3.5 and 6.1 percent of people experience such a phobia(恐惧症) of spiders. Phobias can stop people from traveling, working and enjoying their lives.

Ben-Ezra hopes that their movie research might help people with phobias. But they caution that people with phobias shouldn’t just run out and watch movies and expect their fear to go away. “What we did is only the first step in a very long road,” Ben-Ezra says. “We didn’t say you’ll be cured. We don’t have evidence for that.” But eventually, presenting people’s fears in a positive context---such as a superhero movie---might help people surmount their fear or disgust. After all, if spiders produce Spider-Man, maybe they’re not so bad.

【推荐2】A study of almost 2,700 children aged between seven and ten in 38 schools in Barceiona, Spain, first researches the impact of traffic noise on child cognitive (认知的) development over time.

The children in the study are in a critical stage for the development of memory and attention skill, which are essential to learning. The research found that children exposed to about three times more traffic in the street than other children had memory development that was 23% slower and attention ability development 5% slower over a year.

Noise is the second most damaging environmental factor to health, after air pollution, and, for example, was already known to increase heart attacks in adults. The UN said that urban noise pollution was growing into a global public health threat, leading to 12,000 early deaths a year in the EU alone and affecting many cities.

But research on the impact of road noise on children was limited until now. “We do not know that noise can actually be toxic (有害的) from a physical point of view,” said Dr. Maria Foraster, from the Barcelona Institute for Global Health, who led the study. “We think that we adapt to it, but research has shown that we don’t completely—we still have a physiological (生理的) response.

The research revealed that peaks of noise heard inside the classroom, such as the passing of loud trucks, had more impact than a higher average level of noise. It also found higher noise levels at school were more damaging than at home.

Prof. Iroise Dumontheil, at Birkbeck, University of London, UK, said, “This carefully designed study provides convincing evidence. Considering that many European children living in large cities are exposed to high road-traffic noise levels, this study has implications for public policy to reduce road-traffic noise near schools.”

The research follows previous work that showed higher levels of aircraft noise at school affected reading comprehension and cognitive development. Next, the authors said, they would like to see their findings replicated (复制) in different cities and towns, where schools may be

【推荐3】When you go to the doctor, you like to come away with a prescription(诊断). It makes you feel better to know you will get some medicine. But the doctor knows that medicine is not always needed. Sometimes all a sick person needs is some reassurance that all will be well. In such cases the doctor may prescribe a placebo.

A placebo is a sugar pill, a harmless shot, or an empty capsule. Even though they have no medicine in them, these things seem to make people well. The patient thinks it is medicine and begins to get better. How does this happen?

The study of the placebo opens up new knowledge about the way the human body can heal itself. It is as if there was a doctor in each of us. The doctor will heal the body for us if we let it. But it is not yet known just how the placebo works to heal the body. Some people say it works because the human mind fools itself. These people say that if the mind is fooled into thinking it got medicine, then it will act as if it did, and the body will feel better.

Placebos do not always work. The success of this treatment seems to rest a lot with the relationship between the patient and the doctor. If the patient has a lot of trust in the doctor and if the doctor really wants to help the patient, then the placebo is more likely to work. So in a way, the doctor is the most powerful placebo of all.

A placebo can also have bad effects. If patients expect a bad reaction to medicine, then they will also show a bad reaction to the placebo. This would seem to show that a lot of how you react to medicine is in your mind rather than in your body. Some doctors still think that if the placebo can have bad effects it should never be used. They think there is still not enough known about it.        

The strange power of the placebo does seem to suggest that the human mind is stronger than we think it is. There are people who say you can heal your body by using your mind. And the interesting thing is that even people who swear this is not possible have been healed by a placebo.

【推荐2】Unluckily, there are some rules that teenagers should be allowed to learn in school, but not. They are important to teenagers, although not all of them have to do with their subjects.

Rule 1: Life is not fair. Try to learn to get used to it. Many people won’t understand the real meaning of this rule until they’ve failed to find fairness again and again.

Rule 2: The real world won’t care about you as much as your school does. It will expect you to learn to understand the real world after you leave school. Then you’ll be sure of what to do with real world.

Rule 3: If you think your teacher is terrible, wait until you get a boss. Your boss won’t ask how you feel about your work and will never give you more care or help. He’ll only care about how much money you can help him earn.

Rule 4: TV is not real life. Your life is not a sitcom (情景喜剧). Your problems won’t be solved in 30 or 45 minutes. In real life, people usually have to leave the coffee stores to look for jobs.

Rule 5: Smoking does not make you look cool. Instead, it makes you look moronic (低能的). At the same time, purple hair and pierced body parts make you look like a silly kid. A grown-up teenager should know how to be smart.
