Secondhand smoke kills Chinese women who don't smoke

ICA

A new American study by the Vanderbilt University School of Medicine in Nashville, Texas, found a link between passive smoking and mortality among Chinese women who do not smoke. The study examined 72,829 women who had never smoked and found that about 65,000 of them were exposed to passive smoking by their husbands. Also, about 66,000 were exposed to passive smoking at their workplace or were exposed at a young age to the smoking of one or two family members. During the study, all causes of death were examined, especially heart disease, blood vessels and cancer. Analysis of the results of the study shows that exposure to forced smoking by the husband increases by 15% the risk of death from any cause and even by 37% the risk of death from cardiovascular diseases. It also emerged that exposure to secondhand smoke at work increases the risk of death from cancer by 19%, especially lung cancer, with a 79% higher risk, while exposure to secondhand smoke at a young age increases the risk of death from cardiovascular disease by 26%. The study's conclusions are that exposure to forced smoking, by the husband, at home or at work, increases the risk of death from various diseases, especially from cardiovascular diseases and lung cancer. The study was published in the latest issue of the British Medical Journal (BMJ).

Miri Ziv, CEO of the Association to Fight Cancer said in response that: "The results of this study reinforce the knowledge that has been accumulating by scientists in recent decades, which proves that passive smoking has a direct impact on the development of various cancers and heart diseases. It is important to know that passive smoking is forced smoking, which occurs when children or family members who do not smoke inhale smoke from cigarettes smoked by their parents or family members, who are near them. The smoke emitted into the air space from the cigarette's combustion area and from the smoker's mouth or nose contains a similar amount of toxins to the composition of the smoke that the smoker himself inhales into his lungs, despite the fact that the smoke dissipates in the air of the home space. The study also proves unequivocally that passive smoking kills. Every year, approximately 1,500 women and men die in Israel from second-hand smoke, to which they are exposed at home, in the workplace and in public places of recreation. I call on the public who smoke, stop smoking, and if you are unable to do so, at least avoid smoking around people who do not smoke."

What are the harms of passive smoking?
Cigarette smoke with its green color contains about 4,000 different chemicals, including about 350 toxic substances whose effects are evident in different body systems. About 43 of them have been proven to be carcinogenic. All of these are inhaled into the lungs of the passive smoker, thus passive smoking causes health damages similar to the damages of active smoking. Studies conducted around the world have proven that carcinogenic substances are absorbed in the passive smoker's body, similar to those absorbed in the body of smokers. Passive smoking in the short term causes eye irritation, headache, nausea and dizziness. The morbidity rate from lung cancer and heart disease among non-smokers living with smoking partners is about 25% higher than among people whose partners do not smoke. From the data of the World Health Organization, it appears that there is an increase of about 25% in the risk of lung cancer and myocardial infarction, among passive smokers. A new study conducted in hospitals in London and the results of which were announced in June 2004 states that the risk of suffering from heart and artery diseases as a result of passive smoking is even doubled and is estimated at about 60% - 50%. Additional and long-term studies are required to determine the exact percentage.

The relationship between smoking damage and the development of diseases
Exposure to smoking damages the oxygen absorption mechanism in the human body. About 90% of the particles found in smoke remain in the respiratory tract and lung tissue. These substances first destroy the cilia, coating cells with fine hairs found on the inner wall of the bronchi in the lungs. The cilia move at a rate of 1,000 movements per minute in the opposite direction to the air entering the lungs. In their movement, which is likened to the movement of a conveyor belt, they remove particles that enter the respiratory tract and even mucus upwards. As mentioned, the smoke damages the cilia and they are no longer able to fulfill their role and eliminate the increased amounts of mucus and the mucus remains trapped in the bronchi and accumulates in them.

The chemicals in secondhand smoke with the harmful particles further irritate and destroy the cells in the bronchial walls. This creates wounds through which bacteria and other pests penetrate into the cells. This is how bronchitis develops, which develops over time into chronic inflammation and may get complicated and gradually develop into lung cancer and other types of cancer and even cause other serious diseases such as heart disease, diseases of the blood vessels, and more. The longer you are exposed to secondhand smoke, the more you risk.

Facts about passive smoking

• Every year, approximately 1,500 people die in Israel as a result of exposure to passive smoking, which causes diseases such as lung cancer, throat cancer, throat cancer, colon cancer, bladder cancer, kidney cancer, pancreatic cancer, cervical cancer, as well as heart disease, stroke, Sudden death and more. According to the American Environmental Protection Agency EPA (US Environmental Protection Agency), this is the largest preventable environmental cause of death.
• Every year in the USA about 40,000 people die as a result of heart diseases caused by passive smoking.

The harm of passive smoking in domestic animals

A study recently published at the University of Massachusetts and published in The American Journal of Epidemiology found a clear correlation between passive smoking next to cats and the development of cancer in the lymph nodes in cats. According to the study, the chances of cats exposed to cigarette smoke to develop lymphoma are on average 2.4 times greater than the chance that the disease will develop in cats not exposed to smoke. The researchers believe that some of the ingredients released into the air when smoking tobacco products have a cancer-inducing effect on the tissues of the lymph nodes in cats.
