Advances and conclusions on the harmof smoking.

Smoking in China now exceeds 300 million, accounting for one-third of the world's total smokers.
, although tobacco control measures have been introduced everywhere, and constantly promote the dangers of smoking, but China's tobacco industry market sales are slow growth.
Although smokers know that smoking is harmful to health, it is not clear that smoking will cause damage to the lungs, but also damage to the skin, vision, cardiovascular and so on.
below, through the latest research progress, together to understand the harm of smoking under what? Smoking Harm One: Significantly reduced color difference recognition ability in the United States Rutgers University conducted a study on the impact of smoking vision, in these more than 130 adult (25-45 years old) volunteers, 63 people are smokers, these people smoke more than 20 cigarettes a day, the other 70 people are basically non-smoking, the number of smoking in the lifetime less than 15.
tested, these people have normal or corrected vision.
the researchers tested the volunteers' ability to distinguish contrast (the nuances of shadows) and color, and found that the smoking volunteers showed more or less color blindness or weakness, especially red-green and blue-yellow.
this suggests that long-term smoking can lead to loss of overall color perception or the risk of associated macular degeneration.
The dangers of smoking: The ability to fight melanoma has declined The University of Leeds analysed more than 700 melanoma patients in the UK and found that they had a 60 per cent increased chance of survival within 10 years of not smoking.
Why is this? The researchers believe that smoking affects the body's immunity and leads to a decline in the ability to fight melanoma.
therefore recommends that melanoma patients with smoking habits should quit smoking as soon as possible.
the harm of smoking three: Induced rheumatoid arthritis Karolinska Medical School in the Karolinska School of Medicine, more than 34,000 participants aged 54-89 years of age, compared to smoking for more than 20 years, smoking for more than 20 years of participants, the risk of rheumatoid arthritis increased by 1.6 times;
the study found that a special human gene combined with substances in tobacco, will cause autoimmune response in the joint site, induced inflammation.
rheumatoid arthritis will become chronic as smoking periods extend.
people with chronic rheumatoid arthritis, in the changing weather or winter, that taste is really sore.
the harm of smoking four: affect the synergy of brain regions What is the synergy of brain regions, in short, the various functions of the human brain are coordinated by the cooperation between different brain regions.
an international team of researchers from Fudan University, the University of Warwick, Oxford University and the University of Cambridge in China, which spent two years finding that the brain function connectivity of smokers showed a general decline in brain function connectivity, and that smoking was less sensitive to brain punishment function.
The Harm of Smoking 5: Smoking Leads to Semen Abnormality November 20, 2018 China's Male Reproductive Health Survey found that 51.37 percent of men who smoked, of whom 39.3 percent smoked more than 10 cigarettes a day, and 60.3 percent smoked for more than five years.
, 54.86 percent of men who were infertile smoked and 32.34 percent of men who smoked abnormally.
Note: The survey covered 25 medical units in 16 provinces (districts and municipalities) and received 4,364 valid questionnaires.
the dangers of smoking: Fathers smoke, sonsperm halved Sweden Lund University researchers in Sweden researchers surveyed 104 Swedish men between the ages of 17 and 20 found that male offspring had 41 percent lower sperm concentration and 51 percent lower sperm count than non-smoking men's sons.
In the past, studies have shown that father smoking can also lead to impaired sperm DNA and deformities in offspring.
the volunteers and investigators above are mostly men, and here's a special group - pregnant women.
what harm does it do to the fetus if a pregnant woman smokes? Researchers from the Department of Public Health at The University of Auhus in Denmark found that children of pregnant smokers reached puberty on average six months earlier than nonsmokers.
team recently reported in the journal Toxicology That the chemicals produced by smoking have been shown in experiments to have harmful effects on liver cells in the fetus, and that the effects can have different effects on both male and female fetuses.
children born to mothers with a long history of smoking were more inherited into 3,000 harmful genetic material than those born to mothers with no history of smoking, which would lead to abnormalities in the child's acquired characteristics.
surveyed 6,000 mothers and newborns.
researchers have come to the conclusion that although the fetus cannot breathe in the mother, it may receive harmful genetic material through the blood.
these will change the chemical characteristics of the fetus's genes.
, Chen Baiyan, an assistant researcher at the Institute of Plant and Microbiology at the Chinese Academy of Sciences in Taiwan, has worked with researchers at the University of California, USA, to study reproductive cells in human embryos and found that if pregnant women smoke in the early stages, they can harm the reproductive cells in the embryo and lead to infertility in the next generation.
these are the latest research on the dangers of smoking, in fact, smoking is particularly harmful, even in the next generation will have an impact, the University of Bristol in the United Kingdom, Professor Marcus Pambre's research found that grandmother smoking during pregnancy, the grandmother's social skills, the risk of autism is 67 percent higher.
the above study is only a part, the harm of smoking is very large, infinite, such as smoking will increase the possibility of lung cancer, diabetes, cardiovascular and other diseases, after reading these, do you dare to smoke?
