What are the dangers of long-term secondhand smoke?
-
Smoking causes heart disease, and this applies not only to people who actually smoke but also to non-smokers who are exposed to secondhand smoke. Exposure to secondhand smoke can lead to acute coronary heart disease, and even short-term exposure to secondhand smoke can increase the risk of coronary heart disease. The harmful substances in secondhand smoke can cause severe cardiovascular toxicity, impair the normal function of the heart, blood and vascular systems, and increase the risk of cardiovascular events.
Exposure to secondhand smoke can also worsen the severity of heart attacks, increasing the risk of death and death.
Dr Neal L. Benowitz, Ph.D., Director of the Brandland Center for Excellence in Secondhand Smoke at the UC Old Hill Pilot Medical InstituteBenowitz says exposure to secondhand smoke allows you to inhale the same chemical composition as active smoking, and for a longer period of time than active smoking. Studies have shown that non-smokers exposed to secondhand smoke can find that platelets in the blood are activated within minutes, and the function of the blood fibrillator is impaired, with some effects lasting for several hours.
2. The harm of second-hand smoke to memory.
Terrence O'Neill and Tom Hefernam, members of the Drug and Alcohol Research Group at the University of Semibria, compared the memories of 27 smokers and two groups of non-smokers.
The first group of 27 non-smokers regularly inhaled secondhand smoke. They either live with smokers or spend a lot of time with smokers. For about four and a half years, an average of 25 hours per week were exposed to secondhand smoke.
The second group of 29 non-smokers was infrequent in second-hand smoke. The researchers tested three groups of volunteers with two methods, namely memories of future events and activities. One of the tests is to ask volunteers to remember a specific time before participating in an activity, and the other is to ask them to remember a future event or activity.
Nonsmokers who were regularly exposed to secondhand smoke scored 20% lower on memory tests than the other group of nonsmokers. In a second-degree smoke environment, smokers scored 30% lower than non-smokers who were less violent.

Second-hand smoke can not only damage children's respiratory system but also cause secretory otitis media, if you are in the environment of second-hand smoke for a long time, a large amount of nicotine contained in the smoke can enter the lungs with breathing, affecting the respiratory system, and at the same time flow to all parts of the body through blood exchange, causing secretory otitis media. In addition, long-term exposure to secondhand smoke can also easily affect heart function.
Second-hand smoke is the smoke released from the combustion end of tobacco products, also known as passive smoking, tobacco combustion will release tar, nitrogen, nicotine and other harmful chemicals, including carcinogens, long-term inhalation of second-hand smoke will also cause certain damage to the body. Because it mainly enters the body through breathing, the damage to the respiratory system is greater, and children can have symptoms such as cough and sputum production. At the same time, after nicotine enters the blood, it spasms small blood vessels, resulting in the hardening of the micro-return arteries that supply blood to the inner ear, resulting in insufficient blood supply to the inner ear, causing venous dilation and congestion of the mucosa of the middle ear, enhanced permeability of the blood vessel wall, and leakage in the tympanic chamber, which is easy to cause secretory otitis media due to long-term accumulation, and children may have symptoms such as hearing loss, earache, tinnitus, and ear tightness.
In addition, due to the smoking of the surrounding population, exposure to second-hand smoke in childhood, nicotine metabolites will be detected in the blood samples, and harmful components in the body can cause changes in blood flow, blood vessels, blood pressure and heart rate, and then cause arterial vascular damage and affect heart function. Second-hand smoke is more harmful, in addition to causing certain harm to children, long-term second-hand smoke inhalation by adults may also affect the cardiovascular system, increase the incidence of coronary heart disease, hypertension and other diseases, as well as infertility, infertility and other reproductive system diseases. At the same time, smoking also has a greater impact on oneself, so it is recommended to quit smoking as soon as possible, which is beneficial to one's own health and the health of one's family.

1. Cause lung cancer.
Studies have found that women whose husbands smoke regularly are more likely to develop lung cancer than others. In general, the longer the husband smokes, the greater the addiction to smoking, the deeper the degree of victimization of the wife, and the higher the risk of lung cancer.
2. Induce coronary heart disease.
Frequent passive inhalation of secondhand smoke often affects blood lipids, which may lead to thickening of blood lipids, slower blood circulation, and affect the blood supply and oxygen supply to the myocardium.
3. Suffering from respiratory diseases.
Prolonged exposure to secondhand smoke can also lead to respiratory diseases, especially in children. The harmful substances in the smoke affect the respiratory system and often induce bronchitis, pneumonia, asthma, etc.
4. Cause fetal malformations.
Pregnant women should stay away from second-hand smoke, if pregnant women passively inhale second-hand smoke for a long time, the harmful substances in the smoke are inhaled into the body, often through the placenta to harm the baby, resulting in fetal hypoxia, developmental malformations, etc.
Reducing or not smoking is the most important way to prevent and control second-hand smoke, but restricted by many objective factors, special occasions can not be satisfied, keep indoor air clean, choose to buy indoor air purification products, become another main way to prevent and control second-hand smoke, but in the choice of indoor air purification products need to consider several factors: high safety, fast smoke removal time, wide use area, long action time, authoritative certification, etc., in short, it is very important to choose the air purification products suitable for yourself.

Exposure to secondhand smoke has many dangers to the body. First, secondhand smoke can lead to air pollution, which can lead to respiratory diseases such as asthma, bronchitis, and pneumonia. Second-hand smoke can lead to cardiovascular diseases such as heart disease, stroke, and arteriosclerosis.
In addition, secondhand smoke can cause tumors such as lung, mouth, and stomach cancers. Finally, secondhand smoke can lead to weakened immunity, making people more susceptible to infectious diseases. In conclusion, secondhand smoke has many harms on the body, and you should try to avoid secondhand smoke.

First, people who often inhale second-hand smoke, the chance of developing lung cancer is greater than that of people who are not often exposed to second-hand smoke, the nicotine content in second-hand smoke is higher than the nicotine content in mobile smoke, and the harm to people is greater, and you also contain more than a dozen strong carcinogens in the smoke of second-hand smoke, which is very harmful to people's bodies. If a person is exposed to secondhand smoke for an hour, that is, inhales secondhand smoke for more than an hour, it is equivalent to smoking a cigarette. Passive smoking is very harmful to people's bodies, so if there are people around you who smoke, you should strongly discourage these people or stay away from them.
2. Affect intellectual development. If children are regularly exposed to secondhand smoke, their mental development may be slower, because the nicotine in smoke can harm children's intelligence, and children who are regularly exposed to secondhand smoke may have poor memory. Studies have shown that children who are often exposed to second-hand smoke develop much more intellectually than children who are not regularly exposed to second-hand smoke, so if some parents like to smoke, they can no longer continue to smoke for the sake of their children.
3. Risk of asthma. Children who often inhale second-hand smoke may suffer from asthma and other respiratory diseases, because children who often inhale second-hand smoke have relatively low immunity, and children do not know how to protect themselves, nor do they deliberately avoid the environment with second-hand smoke. If a pregnant woman is exposed to second-hand smoke for a long time, it may have a greater impact on the fetus, and in severe cases, it may also affect the intelligence of the fetus.
I hope everyone can stay away from those who smoke, because smoking also brings harm to yourself. After all, second-hand smoke is also very harmful, and second-hand smoke also makes people feel very frightened. If everyone can avoid it well, then they also have a certain amount of protection for their health, which is also a very good phenomenon.
After all, second-hand smoke is worse than smokers, and second-hand smoke can make people feel very uncomfortable.
It seems that the popular science knowledge about smoking and health needs to be further popularized We generally say that second-hand smoke is more harmful than first-hand smoke refers to the harm of tobacco smoke itself, not that active smokers are harmed more or less than non-active smokers Generally, the duration of each first-hand cigarette will not exceed 20 minutes, but the second-hand smoke or even third-hand smoke produced by it may exist in the room for hours or even months, and the harm to the human body is long-term and long-lasting. What's more, secondhand smoke generally contains more harmful substances than first-hand smoke, because it is composed of smoke that comes out directly from the burning end of tobacco and smoke that enters the smoker's respiratory tract from the filter and then exhales - the smoker does not inhale the smoke emitted from the burning end unless he can stay in the house for a while after smoking But because first-hand smoke and second-hand smoke are produced at the same time, smokers are still exposed to secondhand smoke. When he finished smoking, he became a second-hand smoker just like us, maybe mine can't meet your requirements, but the truth is so cruel, for more information about the dangers of secondhand smoke, please consult the U.S. Surgeon General or the World Health Organization's Tobacco Free Initiative, and there are some relevant content in my personal NetEase blog and Voice of Tobacco Control forum.
Traditional Chinese medicine has always paid attention to the homology of medicine and food, and attaches great importance to improving the body's ability to resist diseases by regulating diet. However, people should first understand the medicinal effects of food when eating, such as eating white radish, which is more suitable for those with phlegm and cough; Edible lilies are better to boil porridge and boil water; Eating mung beans is suitable for people with strong internal fire; Water chestnuts can clear away heat and generate water, and can be eaten raw or boiled in water. At the same time, due to the large differences in people's individual qualities, it is necessary to choose food according to their own conditions when taking it, and pay attention to avoid eating too spicy, salty, greasy and other foods at the same time. >>>More
Another study published showed that cat owners who smoked had three times the risk of lymphoma in their cats compared to other cats. Lymphoma is the most common cancer in cats, with a rate of only 50%. >>>More
Passive smoking refers to the reluctance of a person who does not want to smoke to inhale the smoke from others and the smoke emitted in the environment when a cigarette is burned. Passive smoking is also known as "forced smoking", "indirect smoking" and "secondhand smoke". Because passive smoking inhales several to 50 times more toxic substances than active smokers, they can invade the lungs and damage the cells lining the arteries, promoting atherosclerosis. >>>More
