Parents who smoke often open a window or turn on a fan to clear the air for their children, but experts now have identified a related threat to children's health that isn't as easy to get rid of: third-hand smoke。
That's the term being 1 to describe the invisible yet poisonous mixture of gases and particles(颗粒) clinging(依附) to smokers' hair and 2 , not to mention cushions and carpeting, that stays long after second-hand smoke has cleared from a room. The remaining 3 heavy metals, carcinogens(致癌物) and even radioactive materials that young children can get on their hands and take in, 4 if they're crawling or playing on the floor。
Doctors from MassGeneral Hospital for Children in Boston coined the term "third-hand smoke" to 5 these chemicals in a new study that 6 on the risks they pose to infants and children. The study was published in the 7 issue of the journal Pediatrics。
"Everyone knows that second-hand smoke is bad, 8 they don't know about this," said Dr. Jonathan P. Winickoff, the lead author of the study and an assistant professor of pediatrics at Harvard Medical School。
"When their kids are 9 the house, they might smoke. Or they smoke in the car. Or they strap(用带子捆扎) the kid in the car seat in the back and crack the window and 10 , and they think it's okay because the second-hand smoke isn't getting to their 11 . We needed a term to describe these tobacco toxins that aren't 12 ."
The study reported on 13 toward smoking in 1,500 households across the United States. It found that the vast majority of both smokers and nonsmokers were 14 that second-hand smoke is harmful to children. Some 95 percent of nonsmokers and 84 percent of smokers 15 with the statement that "inhaling smoke from a parent's cigarette can 16 the health of infants and children"。
But 17 fewer of those surveyed were aware of the 18 of third-hand smoke. Since the term is so new, the researchers asked people if they agreed with the statement that "breathing air in a room 19 where people smoked yesterday can harm the health of infants and children"。
Only 65 percent of nonsmokers and 43 percent of smokers agreed with that 20 , which researchers interpreted as acknowledgement of the risks of third-hand smoke。

It seems parents have long been right. Going to bed early is key to getting enough sleep and helping adolescents feel on top of the world, a new study reported.
A 1 of sleep among youngsters may 2 depression and suicidal (自杀的)thoughts, according to the study by the Columbia University Medical Center.
"Our results are 3 with the theory that inadequate sleep is a risk factor for depression, working with other 4 and protective factors through multiple possible causal pathways to the development of this 5 disorder," said lead author James Gangwisch.
" 6 quality sleep could therefore be a preventative measure against 7 and a treatment for depression," he added in the study 8 in the Friday issue of Sleep magazine.
The study followed the nightly habits of some 15,659 college and high-school students, and 9 those who consistently went to bed 10 midnight had a 24 percent higher risk of depression than those who turned in before 10:00 pm.
Night owls（夜猫子）also ran a 20 percent 11 risk of battling suicidal thoughts, the study added.
The American Academy of Sleep Medicine 12 that adolescents should sleep at least nine hours or more a night. Those who were tucked in before 10:00 pm reported they slept 13 about eight hours and 10 minutes.
But that amount of sleep 14 significantly for those in bed after midnight.
And adolescents who slept five hours or less a night were 71 percent more 15 to suffer depression and 48 percent more 16 becoming suicidal, the study said.
"It is a common perception and societal 17 that adolescents do not need as much sleep as pre-adolescents, yet studies suggest that adolescents may 18 require more sleep," said Gangwisch.
"Studies have found that adolescents do not go to bed 19 enough to make up for earlier school start times, and transitions to earlier school start times have been shown to be 20 with significant sleep deprivation（剥夺）. "

Don't blame genes for aging facial skin. A new study of twins suggests you can 1 those coarse(粗糙的) wrinkles, brown or pink spots, and dilated(膨胀的) blood vessels on too much time in the sun, smoking, and being overweight.
Because twins share genes, but may have 2 exposures to environmental factors, studying twins allows an, "opportunity to control for genetic susceptibility(敏感性)," Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and colleagues 3 in the latest issue of Archives of Dermatology.
Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is 4 more to environment and lifestyle than 5 factors.
But when it 6 skin cancer, the researchers say their findings support previous reports that 7 environment and genes affect skin cancer risk.
Baron's team 8 facial skin of 130 twins, 18 to 77 years old, who lived 9 in the northern Midwest and Eastern regions of the U.S. who were 10 the Twins Days Festival in Ohio in August 2002.
At this time, each of the twins also 11 reported how their skin burned or tanned 12 sunscreen(防晒霜), their weight, and their history of skin cancer, smoking, and alcohol drinking.
The study group 13 of 52 fraternal and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status. Identical(同卵的) twins share all of their genes and fraternal twins share only about half.
From these data, the researchers 14 strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental 15
16 contrast, sunscreen use and drinking alcohol appeared correlated with 17 skin damage.
Baron and colleagues say the current findings, which highlight ties between facial 18 and potentially avoidable 19 factors -- such as smoking, being overweight, and 20 overexposure to the sun's damaging rays -- may help motivate people to minimize these risky behaviors.

Cutting meat production and consumption by 30 percent would help to reduce carbon emissions(排放) and improve health in the most meat-loving nations, scientists said on Wednesday.
Using prediction models, British and Australian researchers 1 that improving efficiency, increasing carbon capture and 2 fossil fuel dependence in farming would not be enough to 3 emissions targets.
But combining these steps 4 a 30 percent reduction in livestock（家畜） 5 in major meat-producing nations and a similar 6 in meat-eating, would lead to "substantial population health benefits" and cut emissions, they said.
The study found that in Britain, a 30 percent 7 intake of animal-source saturated（饱和的） fat by adults would reduce the 8 of premature（过早的） deaths from heart disease by some 17 percent -- equivalent to 18,000 premature deaths reduced in one year.
In Sao Paulo, Brazil, it could mean as 9 as 1,000 premature deaths reduced in a year, they said.
10 the United Nations Food and Agricultural Organization, 18 percent of all greenhouse gas emissions are from meat production and experts say rising 11 for meat, particularly in countries with growing economies, could 12 livestock production up by 85 percent from 2000 levels 13 2030.
The scientists said global action was needed to maximize the benefits of cutting meat production and 14 , and that the environmental 15 "may apply only in those countries that currently have high production levels."
The study was 16 in The Lancet medical journal as part of a series in climate change and health 17 the Copenhagen global climate summit scheduled next month.
In a second study, British scientists found that increased walking and cycling, and 18 cars, would have a much greater impact on health 19 low-emission vehicles in rich and middle-income countries.
Andrew Haines, director of the London School of Hygiene and Tropical Medicine and head of the research series, said delegates at Copenhagen needed "to understand the potential 20 impacts of their plans."

Elderly people who drink several cups of green tea a day are less likely to suffer from depression, probably due to a "feel good" chemical found in this type of tea, Japanese researchers said.
Several studies have 1 drinking green tea to lessening psychological problems and Kaijun Niu, of Tohoku University Graduate School, and colleagues found people 2 70 and older who drank four or more cups of green tea daily were 44 percent 3 likely to experience depression.
Green tea is widely 4 in many Asian countries, 5 China and Japan.
Niu's team 6 1,058 relatively healthy elderly men and women. About 34 percent of the men and 39 percent of the women had symptoms of 7 , according to the study that was 8 in the American Journal of Clinical Nutrition.
A total of 488 participants said they 9 four or more cups of green tea a day, 284 said they downed two to three cups 10 and the rest reported having one or fewer cups daily.
According to the researchers, the 11 effect of drinking more 12 tea on alleviating symptoms of depression did not 13 after they factored in social and economic status, gender, diet, history of medical problems and 14 of antidepressants.
There was no 15 between consumption of black or oolong tea, or coffee, and 16 symptoms of depression.

Seasonal influenza is characterized by a sudden fever, cough, headache, muscle and joint pain, sore throat and runny nose. Most people recover from fever and 1 symptoms within a week without requiring medical attention. But influenza can 2 severe illness or death in people at high risk. The time from infection to illness is about two days.
Yearly influenza epidemics can 3 affect all age groups, but the highest risk of complications occur among children younger than age two, adults age 65 or older, and people of 4 age with certain medical conditions, such as chronic heart, lung, kidney, liver, blood or metabolic diseases, or weakened immune systems.
Seasonal influenza 5 easily and can sweep through schools, nursing homes or businesses and towns. When an 6 person coughs, infected droplets get into the air and another person can breathe them 7 and be exposed. The virus can also be spread by hands infected with the virus. 8 transmission, people should cover their mouth and nose with a tissue when coughing, and 9 their hands regularly.
Drugs for influenza are 10 in some countries and effectively prevent and treat the illness. Some influenza viruses develop 11 to the antiviral medicines, limiting the effectiveness of treatment.
Influenza epidemics occur 12 during autumn and winter in temperate regions. Illnesses result in hospitalizations and deaths mainly among high-risk groups. Worldwide, these annual epidemics result in about three to five million 13 of severe illness, and about 250 000 to 500 000 deaths.
Influenza can cause serious public health and economic problems. In 14 countries, epidemics can result in high levels of worker absenteeism and productivity 15 . 16 most people recover from a bout(轮) of influenza, there are large numbers of people who need hospital treatment and many 17 die from the disease every year. 18 is known about the effects of influenza epidemics in developing countries.
The most 19 way to prevent the disease or severe outcomes from the illness is vaccination. Vaccination is especially important for people at higher risk of serious influenza complications, and for people who live with or care 20 high risk individuals.
