CHICAGO (Reuters) - Smoking not only can wrinkle(起皱纹) the face and turn it yellow -- it can do the same to the whole body, researchers reported on Monday.
The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body -- even skin protected from the sun.
"We examined non-facial skin that was protected from the sun, and found that the total number of packs of cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr. Yolanda Helfrich of the University of Michigan, who led the study, said in a statement.
"In participants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers. Similar findings were seen in participants aged 45 to 65 years," Helfrich's team added in their report.
The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged in age from 22 to 91 and half were smokers Independent judges decided how wrinkled each person's skin was.
When skin is exposed to sunlight, notably the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich's team wrote.
Several previous studies have found that cigarette smoking contributes to premature（过早的）skin aging as measured by facial wrinkles, the study said, but little has been done to measure the aging of skin not exposed to light.
The report did not discuss the mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels（血管）beneath the skin to constrict（紧缩）, reducing blood supply to the skin.
Smoking can also damage the connective tissue that supports both the skin and the internal organs.

When people in the U.S. have company or when they're invited to (formal or informal)get-together, they usually make a point of trying to make others feel comfortable and relaxed.On the whole, they tend to be informal. Men shake hands, but usually only when they're introduced. Male friends and business associate who haven't seen each other in a while may shake hands when they say hello. Women usually don't shake hands when being introduced to each other. When a woman and man are introduced, shaking hands is up to the woman. Americans rarely shake hands to say goodbye, except on business occasions. American women are used to being independent. They are used to going to places by themselves, making their own money, and often living alone. Sometimes they will ask men for help, but they usually don't want to be protected. Since the women's movement started, it's not always clear whether women expect men to open doors or help them into their coats. American women may start conversations with men or even ask them to dance.
There are a lot of Americans who don't smoke or drink, and many who don't want people to do those things in their houses. It's always best to ask for permission before you,bring alcohol to a dinner or before you light up a cigarette, if you are with people you don't ,know very well. Non-smokers have become more militant (好战的) about smoking in public places. Many restaurants, for example, have set up special areas for smokers.
House guests may bring gifts when they come to visit, and they often offer to help in some way. As a guest, you may want to ask your host or hostess if there's anything you can do to help in the kitchen. In many cases, the gesture is more important than actually helping.
