You know what the harms of secondhand smoke are

What I understand is that long-term inhalation of second-hand smoke will increase the risk of lung cancer, and if it is inhaled by pregnant women, it will also affect the development of the fetus, and if it is inhaled by children, it is easy to cause children to suffer from asthma.

It may affect your digestive system, your lungs, and you may experience some congestion or edema. There is also the possibility of affecting your digestive system. There is also the possibility of cardiovascular and cerebrovascular diseases, and secondly, it may affect their future life.

The chance of cancer also increases.

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.

The content of harmful substances in second-hand smoke is much higher than that of first-hand smoke, so frequent passive secondhand smoke is very harmful. It may cause lung cancer, coronary heart disease, respiratory diseases, etc.; Pregnant women are exposed to secondhand smoke, which can cause fetal malformations.

Some people don't smoke themselves, but they smoke a lot at home or at work, and they passively inhale secondhand smoke every day. The content of harmful substances in second-hand smoke is much higher than that of first-hand smoke, so how harmful is it to smoke secondhand smoke regularly?

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 the circulation speed of blood stains, affecting the blood supply and oxygen supply to the myocardium, and the risk of coronary heart disease is often significantly increased.

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 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 major 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 effect, authoritative certification, etc., in short, it is very important to choose the air purification products that are suitable for you.

Secondhand smoke can have a great impact on the health of the respiratory system, and regular exposure to secondhand smoke is likely to induce lung cancer.

Secondhand smoke can also cause diseases of the cardiovascular system, and even induce myocardial infarction in severe cases.

Secondhand smoke can have a big impact on respiratory health, and regular exposure to secondhand smoke is likely to induce lung cancer. Secondhand smoke can also cause diseases of the cardiovascular system, and in severe cases, it can even induce myocardial infarction. In addition, secondhand smoke can cause hearing impairment and increase the risk of diabetes, and if women regularly inhale secondhand smoke, it can also lead to cervical cancer.

Many people in life have the habit of smoking, and the addiction to smoking is still very big, as long as they are free, they will take cigarettes to smoke, and even no matter what the occasion. Smoking not only harms one's own health, but also exhales those around you to second-hand smoke, which is no less harmful than direct smoking. So, what are the specific hazards of secondhand smoke?

1. Induce lung cancer.

One of the dangers of secondhand smoke is that it can induce lung cancer. Secondhand smoke contains a variety of harmful substances such as tar and nicotine, which will inhibit the activity of human respiratory tract cilia, and also affect the function of macrophages, so that the bronchial mucosa appears edema and congestion, leading to various respiratory diseases, and may induce lung cancer for a long time.

2. Cause cardiovascular system diseases.

The dangers of secondhand smoke also include the fact that pure faith causes various cardiovascular diseases. Secondhand smoke contains a large amount of carbon monoxide, and if people stay in the environment of secondhand smoke for a long time, they will inevitably inhale a large amount of carbon monoxide, resulting in a lack of oxygen in the human body. In addition, nicotine in second-hand smoke will cause abnormalities in blood vessels, long-term hypoxia and vascular abnormalities will greatly increase the incidence of cardiovascular diseases, and in severe cases, it will induce myocardial infarction.

3. Cause hearing impairment.

Secondhand smoke can also cause hearing impairment. Secondhand smoke contains a lot of toxic and harmful substances, and these substances often have a negative effect on the blood activity of the small blood vessels of the ear, so that the organs are deprived of oxygen, and a large number of toxic substances are accumulated, and eventually cause hearing damage.

4. Increase the risk of diabetes.

Regular exposure to secondhand smoke also increases the risk of diabetes. Secondhand smoke can affect the body's tolerance to glucose, which will increase the body's blood sugar and greatly increase the risk of diabetes.

5. Cause cervical cancer in women.

Secondhand smoke contains polycyclic aromatic compounds, which can cause cervical lesions once they enter the human body, and in severe cases, they can lead to cervical cancer and pose a threat to women's life and health. In addition, a variety of harmful substances in secondhand smoke can affect women's reproductive health, leading to irregular menstruation and early menopause, and even infertility.

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. Secondly, secondhand 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, exposure to secondhand smoke can lead to weakened immunity, which is known to make people more susceptible to contracting state diseases. In conclusion, secondhand smoke has many harms on the body, and you should try to avoid 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 cause 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 serious cardiovascular toxicity, damage the normal function of the heart, blood and vascular systems, and increase the risk of cardiovascular events.

Secondhand smoke exposure can also worsen heart attacks and increase the risk of death.

Neal L., Director of the Brandland Center of Excellence for Secondhand Smoke at the University of California, California Pilot Medical Institute, Old MeetinghillDr. Benowitz says exposure to secondhand smoke allows you to inhale the same chemical composition as active smoking, and the exposure time is longer than active smoking. Experimental studies have shown that:

Non-smokers exposed to secondhand smoke can detect platelet activation and impaired blood vessel function within a few minutes, some of which can last for hours.

2. The harm of second-hand smoke to memory.

Terrance O'Neill and Tom Hefernand, members of the Drug and Alcohol Research Group at Northumbria University, compared the memory of 27 smokers with two groups of non-smokers.

The first group consisted of 27 non-smokers who regularly inhaled secondhand smoke. They either live with the smoker or spend a lot of time with the smoker. Exposure to secondhand smoke averages 25 hours a week over about four and a half years.

The second group of 29 non-smokers was infrequently exposed to second-hand smoke. The researchers tested the prospective memories of three groups of volunteers in two ways, namely memories of future events and activities. One of the tests was to ask volunteers to participate in an activity after remembering a specific time, and the other was to ask them to remember an event or activity in the future.

Non-smokers who were regularly exposed to secondhand smoke scored 20% lower on memory tests than the other group of non-smokers. Smokers scored 30% lower than non-smokers who were less likely to be violent in a two-to-smoke environment.

3. The harm of secondhand smoke to pregnant women.

Nicotine and other harmful substances can be detected in the uterine amniotic fluid of 90% of pregnant women who passively inhale secondhand smoke, indicating that tobacco smoke directly pollutes the uterine environment of fetal growth. Secondhand smoke exposure is an important risk factor for pregnancy-induced hypertension and pregnancy complications in pregnant women. At the same time, tobacco exposure has a serious impact on the health of the fetus from the fetal period. Secondhand smoke exposure also affects the proliferation and differentiation of embryonic cells, resulting in abnormal postembryonic development, manifested in developmental disorders of the nervous system and intrauterine growth retardation.

Persuasion is the best. When we see smoking in public, we should try to discourage it, and everyone should be an advocate of a smoke-free environment, so as to protect both themselves and everyone's health.
