I wait for you in the distant plance.Even if can not become

Nowadays, it is possible to travel to distant parts of the globe in several hours. This can result in the traveler ending up in a part of the world where time is different from his or her own “body clock” ,which control our sleep patterns.
If we travel east or west by more than four time zones (hours) then we will usually be affected.
In the past when people traveled by sea, there was enough time for the body to adjust to the local time, but with the advent of modern high speed aircraft the body does not have time to adjust. Therefore, there is the term “jet lag(时差反应)”. It normally takes one day per time zone (hour) for the body to adjust to its new surroundings.
The effects of jet lag are usually tiredness and insomnia (失眠) but can also include: poor concentration, nausea (恶心) ,vomiting (呕吐), constipation (便秘) and general malaise (不舒服). The effects are made worse by alcohol.
Sleeping while flying may help to reduce the symptoms (症状) of jet lag, but long periods of immobility aboard aircraft can make the traveler feel numb(麻木的) in the legs. The following are some other tips of reducing the symptoms of jet lag:
①Avoid traveling when you are already tired and rest before departure.
②Stopovers on long flights may be helpful.
③A relaxed flight is important.
④Sleeping tablets will help you to sleep and be correspondingly alert (相对警惕的) during the next day, but they do not speed up adjustment to the new time zone.
⑤Remember the actual traveling time will usually be at least twice the actual time spent in the air since it will include traveling to and from and hanging around in airports.
⑥Avoid heavy commitments on the first day after arrival.

The smell of fresh air is becoming something of a distant memory, thanks to our increasing use of fragrance (香气). From air fresheners to scented (有香味的) candles, we live in a world of scent.
Recent figures show seven in ten people use air fresheners or scented candles to keep our homes smelling sweet. Yet recent records suggest that perfumed products could affect our health, causing problems including allergies (过敏), headaches and asthma (哮喘) .
One leading expert believes nearly a third of people suffer health effects from being exposed to scents. A major problem is so-called “contact” allergy—where perfumes and scented products cause eczema (湿疹) when they come into contact with the skin. About one in 20 is thought to be affected by fragrance allergy.
“Often it may not be immediately obvious that you have developed a fragrance allergy,” says Dr. Baron. “You don’t react immediately. Gradually, as you are exposed more and more, the body increases its reaction, until it becomes noticeable to you.”
People with pre-existing eczema are particularly vulnerable (易受影响). “The eczema worsens in areas in contact with perfumes,” says Dr. Baron. “But even those without allergies can be at risk of fragrance allergy.” You can become suddenly allergic to perfumes and personal care products that you have been using for years. “Even if you know which fragrance causes a problem, it can be difficult to avoid, as most personal care products –soap, shampoo, sun cream and washing powder—contain fragrances,” says Dr. Baron.
And strong scents can also cause headaches. Fragrances activate the nose’s nerve cells, stimulating the nerve system associated with head pain. To minimize risk, sufferers are advised to minimize the contact.
“Fragrance suggest cleanliness – yet people are smelling a potentially dangerous chemical mixture,” says Anne Steinemann, professor of the University of Washington. “We often use them to mask one problem – as with air fresheners – but create a greater one – adding poisonous chemicals to the air.”
