Is secondhand smoke bad for your health? Please, thank you

China Tobacco**According to Science & Technology** Secondhand smoke is also known as environmental tobacco smoke (ETS). Secondhand smoke includes both mainstream smoke exhaled by smokers and sidestream smoke coming straight from paper cigarettes, cigars, or pipes. Secondhand smoke contains more than 4,000 substances, including more than 40 cancer-related toxins.

In secondhand smoke, the release rate of many compounds in sidestream smoke tends to be higher than in mainstream smoke. The World Health Organization's report shows that smoking is harmful to human beings in many ways, mainly causing asthma, pneumonia, lung cancer, high blood pressure, heart disease and reproductive development. Among them, second-hand smoke is no less harmful to passive smokers than active smokers, especially to children and adolescents.

How can we reduce the damage caused to our bodies by inhaled secondhand smoke? Eat more fresh fruits and vegetables (especially those rich in carotene and vitamin C), because vitamins have antioxidant functions and can fight cancer (such as papaya, tomatoes, carrots, pumpkins and other vegetables and fruits). Drink plenty of water and urinate more.

Exercising more and perspiring more can accelerate the elimination of nicotine from the body.

Medical researchers recently published research suggesting that passive smoking, commonly known as "secondhand smoke," is more dangerous than previously known, and that some women who live with smokers are six times more likely to develop lung cancer. The study, which examined the tissues of 106 women living with smokers in Missouri, found that women with mutations or deficiencies in the gene known as "GSTMI," which is now thought to inactivate tobacco carcinogens, were 2,600 to 6 times more likely to develop lung cancer. "Secondhand smoke" is more harmful than expected, and the researchers say that this study is currently a small-scale experiment and needs to be further confirmed and expanded.

However, if this study is correct, the problem of environmental smoking is far more dangerous than previously known. Lung cancer is considered by the medical community to be a civilized disease, because its seriousness is constantly manifested with the progress of society. Since the beginning of the 20th century, the incidence of lung cancer has increased dramatically, outpacing other cancers.

In the twenties, there were only about 370 reported cases of lung cancer in the world, but by the twenties, the number of lung cancer cases in the United States alone was as high as 1.83 million.

Secondhand smoke is much more harmful to the body than firsthand smoke.

<> first we need to figure out what is"Secondhand smoke"，"Secondhand smoke"Also known as passive smoking, it refers to the mixed smoke released from the burning end of the tobacco product and exhaled by the smoker. Each piece of second-hand smoke contains thousands of chemicals, tar, nicotine and other hundreds of harmful substances, carcinogens are as high as sixty-nine, when the human body inhales second-hand smoke, these harmful substances produced by tobacco combustion will enter the lungs of the human body with human breathing, and then combine with the blood through the capillaries of the lungs, acting on various organ systems of the human body, causing many related diseases.

The diseases that may be caused are roughly divided into two categories: the first type is cancer, the second type is chronic disease, cancer is the cancer of multiple organ systems of the whole body led by lung cancer, in the process of second-hand smoke inhalation, it will pass through multiple tissues and organs of the human body, including oral cancer, laryngeal cancer, including in the process of tobacco excretion, and even the bladder is not spared, and chronic disease, mainly refers to common chronic obstructive pulmonary disease, especially in winter, including coronary heart disease including stroke, after research has found, Tobacco can damage almost all organs and systems of the human body, not everyone will get sick if they inhale second-hand smoke, but one out of every two people will get sick because of inhaling second-hand smoke, because in various organs of the human body, there are always weak parts, then some people may be reflected in the lungs, some people may be reflected in the heart, different people suffer from related diseases are also different, in terms of lifespan, people who often inhale second-hand smoke live an average of ten years less than people who are not exposed to second-hand smoke.

If you get sick because of inhaling other people's second-hand smoke, think about how unworthy it is, so if you have a friend who smokes, if you really can't control your craving, you must advise him to smoke outdoors, in an uncovered place, so that it will not affect the health of others.

Second-hand smoke is more harmful to the body, because second-hand smoke will breathe directly into the stomach, second-hand smoke contains burned carbon monoxide, nicotine, tar, which will cause serious damage to the body.

First of all, it will affect the health of the lungs, which is likely to cause pneumonia or cancer, which will affect the health of the respiratory system, and will lead to a decrease in resistance and immunity.

It affects the human respiratory system, trachea, and lungs, causing people to cough all the time, affecting the cardiovascular and cerebrovascular systems, as well as the blood circulation of the brain, which are all harmful effects of secondhand smoke.

It will lead to lung problems, which can easily lead to damage to one's lungs, easily affect physical health, affect the health of the lungs, and affect normal life.

What are the dangers of secondhand smoke to the human body?

Secondhand smoke contains tar, nicotine and carbon monoxide, which are harmful substances that can easily cause lung cancer. It will affect memory, often absorb second-hand smoke, and can also cause pneumonia and asthma in children, and it is not good for the heart, and second-hand smoke is also very harmful to pregnant women and fetuses.

For lung cancer, the content of harmful substances in cigarettes is very high, with higher levels of nicotine, tar, and carbon monoxide than those ingested by direct smokers. Smoking increases the risk of lung cancer, and secondhand smoke is no exception, and people who live with smokers are often about 6 times more likely to develop lung cancer than normal people.

Secondhand smoke contains more than 40 carcinogens, which can increase the risk of diseases such as lung cancer if inhaled. Studies have shown that if a husband smokes, his wife is more than 200% more likely to get lung cancer than the general population. It also affects fetal growth and development.

% of lung cancers are linked to secondhand smoke.

Studies have found that secondhand smoke has a much shorter lifespan than smokers. Similarly, 25% of people who get lung cancer are caused by regular exposure to secondhand smoke.

2. "Second-hand smoke" directly damages children's lungs and brains.

If the smoker smokes around a pregnant woman or child, it will directly affect the development of the fetus in the womb, and will also affect the child's intelligence and lungs.

3. Women who smoke second-hand smoke are prone to stroke.

Women whose husbands smoke are the first to bear the brunt of "secondhand smoke". A survey has shown that if the husband smokes less than 10 cigarettes a day, the wife's chance of stroke increases by 28%, the husband smokes 10 to 20 cigarettes a day, the wife's chance of stroke increases by 32%, and if the husband smokes more than 20 cigarettes a day, the wife's stroke rate increases by as much as 62%.

4. Smoking causes other cancers.

The latest research has found that in addition to the well-known lung cancer, which is most closely related to smoking, smoking can also affect the occurrence of laryngeal cancer, nasopharyngeal cancer, oral cancer, tongue cancer, esophageal cancer, gastric cancer, pancreatic cancer, bladder cancer, kidney cancer and cervical cancer.

This harm is quite big, because of the second-hand smoke you inhale, this person is a non-smoker, so he is more sensitive to this smoke.
