What are the hazards of inhaling second-hand smoke

What are the hazards of inhaling second-hand smoke is the face of a second-hand smoker swollen into a pig's head? Is the harm of second-hand smoke so great? Recently, Mr. Zhang in Wuhan has experienced this horrible scene. It is reported that when he was on a business trip with his colleagues, his colleagues in the car smoked to refresh their minds. Unexpectedly, Mr. Zhang of his classmates' face swelled into a pig's head the next day and almost died. What's the matter? What's the harm of second-hand smoke? Let's go together Come and have a look!

When I wake up, my whole face is swollen to "pig head"!

More than ten days ago, Mr. Zhang, 54, and several colleagues drove to Qiandongnan, Guizhou Province for business. The road was very busy.

Because of the long time spent on the road, the colleagues in the car began to smoke and refresh themselves, and the smoke in the car filled up. Mr. Zhang's throat became more and more uncomfortable. When he arrived at the destination, his throat was still swollen and painful. But he didn't pay attention to it. Unexpectedly, when he woke up the next morning, Mr. Zhang suddenly found that his left face was swollen to the height of an adult's fist. He still didn't pay attention to it. He just bought some anti-inflammatory drugs and went on with his work.

But on the third day, Mr. Zhang's condition suddenly worsened. His whole face was swollen like a pig's head. He couldn't eat anything. After simple treatment in the local area, he didn't get better. He also suffered from respiratory obstruction. Mr. Zhang was in a hurry and immediately bought a train ticket to go back to Wuhan.

The culprit is second-hand smoke!

In the hospital, the otolaryngologist Jiang found that Mr. Zhang's chin was swollen to the size of two adult fists. According to preliminary judgment, it was peritonsillitis secondary to peritonsillar abscess, which caused parapharyngeal space infection.

The doctor said that Mr. Zhang's illness is so rapid and huge in scope, which is extremely rare. Because his throat and neck have been seriously infected, a large range of purulent cavity has been formed, which oppresses the airway. If he doesn't deal with it again, it may cause suffocation, etc., which will endanger his life!

Emergency! The doctor's team immediately drained all the pus from Mr. Zhang's pharyngeal abscess through operation, and the drained pus reached 300-400ml! At present, under the careful treatment of medical staff, Mr. Zhang recovered well.

Sore throat should be treated as soon as possible!

He just had a bad throat. Why did it turn out to be so serious? Mr. Zhang was puzzled.

According to the doctor's conjecture, this may be due to the decline of the body's immunity due to the tiredness of the journey, coupled with the lack of air circulation and the strong smell of smoke, which continuously stimulate the pharyngeal cavity and cause the infection.

Yuan Kun, director of the otolaryngology department of the hospital, reminded that: some common life problems such as pharyngitis, acute tonsillitis, peritonsillitis, post tooth extraction infection, etc., such as careless treatment or continuous attack, may cause infection not to affect adjacent tissues and organs, cause cellulitis, dyspnea in compressed airway, asphyxia, neck vascular injury, and other complications, such as massive bleeding Serious or even life-threatening. If you have sore throat, you'd better see a doctor as soon as possible, so as not to endanger your health.

What are the hazards of long-term second-hand smoke?

1. Lung cancer

Second hand smoke often contains more harmful substances than mainstream cigarettes, such as twice the amount of nicotine, three times the amount of tar, five times the amount of carbon monoxide and about 50 times the amount of carcinogens, according to China's eating website. According to the calculation, in a place with poor ventilation, the average amount of smoke inhaled by non-smokers within one hour is equivalent to the dose of a cigarette inhaled. According to the survey, smokers have a significantly higher chance of developing lung cancer than non-smokers. Through the analysis of smoke inhaled by smokers, dozens of carcinogens were found in the smoke. The risk of lung cancer is related to the time of smoking. The earlier the age of smoking, the greater the risk. The longer the smoking time, the higher the incidence and mortality of lung cancer.

Women are more vulnerable to tobacco than men. Some women who live with smokers are six times more likely to develop lung cancer. It should be noted that the risk of lung cancer in female smokers is also more serious, 1 or 9 times higher than that in male smokers. Second hand smoke is no less harmful to passive smokers than active smokers, especially to pregnant women and children. Studies have shown that people who smoke 'second-hand smoke' are at the same risk as smokers when they spend more than 15 minutes with them every day. 75% of lung cancer patients were investigated for smoking.

2. Harm to memory

Nicotine and other harmful substances in the smoke stimulate the brain, which can cause cerebrovascular sclerosis and affect brain function. The intelligence development of children who smoke passively for a long time is significantly worse than that of children who grow up in non smoke environment.

Non smokers who were often exposed to second-hand smoke scored 20% lower on memory tests than the other group. Smokers performed worse, scoring 30% lower than non-smokers who were not exposed to second-hand smoke.

3. Cause asthma, pneumonia and ear inflammation in children

Children are the biggest victims of environmental pollution. Generally, children will experience higher environmental exposure than adults, they will breathe more air than adults, so they will inhale more pollutants. In addition, children's hyperactivity, poor self-protection and immune function make them most vulnerable to pollutants. If the father smokes at home, the child will not do anything against him or take some measures to protect himself. He can only be forced to smoke second-hand smoke. However, the harm of secondhand smoke to children's health mainly includes: asthma, sudden death syndrome, tracheitis, pneumonia and ear inflammation.

4. Coronary heart disease

Smoking causes heart disease, not only for those who actually smoke, but also for non-smokers who are exposed to second-hand smoke. Second hand smoke exposure can cause acute coronary heart disease, even if exposure to second-hand smoke for a short time will cause a sharp rise in the risk of coronary heart disease, which is biologically certain.

Smoking increased the risk of coronary heart disease by 4 to 6 times in men and 6 to 9 times in women; exposure to environmental tobacco smoke increased the risk of death from heart disease in non-smoking women, and secondhand smoke significantly increased the incidence of coronary heart disease, ischemic stroke and peripheral vascular disease in women. The causes of coronary heart disease caused by passive smoking are: the chemicals inhaled by passive smoking can make blood fat abnormal, blood sticky, destroy myocardial tissue, reduce the ability of blood vessels to regulate blood pressure and blood flow, and then increase the risk of myocardial infarction.

5. Harm to pregnant women and infants

Nicotine and other harmful substances can be detected in amniotic fluid of 90% pregnant women who smoke secondhand smoke passively, which indicates that tobacco smoke directly pollutes the environment of the uterus where the fetus grows. Second hand smoke exposure is an important risk factor for pregnancy induced hypertension (PIH) and pregnancy complications. At the same time, second hand smoke exposure has a serious impact on the health of pregnant women from the beginning of fetal period. Second hand smoke exposure also affects the proliferation and differentiation of embryonic cells, resulting in abnormal embryonic development, which is manifested in the development of nervous system and intrauterine growth retardation.

If a mother inhales second-hand smoke for a long time during pregnancy, most of the harmful chemicals released from tobacco burning can 'harass' innocent babies through the placenta. In particular, toxic gases such as carbon monoxide will reduce the blood oxygen concentration in the mother's body, which will lead to fetal hypoxia; and nicotine, an addictive drug in tobacco, can cause vascular stenosis and slow down the blood flow, which means that the nutrition and oxygen provided to the fetus will be reduced, which will easily lead to premature birth. However, premature infants are prone to respiratory, digestive and thermoregulatory disorders, and even die shortly after birth.

6. Pharyngitis

Long term secondhand smoke is a common cause of chronic pharyngitis. Tar, nicotine, nicotine and other harmful substances in the smoke can inhibit the activity of respiratory cilia, weaken the purification ability of respiratory tract, cause congestion and edema of bronchial mucosa, so as to make external pathogens enter the bronchus and cause repeated infection of this part, thus leading to chronic pharyngitis.

Smoking second-hand smoke is more harmful than smoking, because the harmful substances contained in the smoke are more than the harmful substances inhaled into the body by smokers, and the substances such as carbon monoxide and nicotine contained in the body of people who smoke second-hand smoke for a long time will be more than smokers themselves, so the risk of chronic pharyngitis is greater than others.

7. Leading to female infertility

From the clinical point of view, smoking will have adverse effects on female reproductive function, sexual function, endocrine and other aspects, increasing the risk of infertility. According to the clinical investigation, the probability of infertility of the direct smokers and the second-hand smokers is 2.7 times higher than that of the non-smokers. At the same time, smoking will seriously damage women's reproductive function, resulting in a lower probability of pregnancy. If both men and women smoke at the same time, the pregnancy rate of women will be lower.

8. Lead to leukemia and tumor

A study in the United States shows that smoking by a husband can increase the risk of leukemia by seven times for a nonsmoking wife. The risk of breast cancer and cervical cancer in 6-45-year-old women who smoke passively at home is 3-4 times higher than that in non-smoking women.

Due to the carcinogens of tobacco, the proportion of adults and children suffering from blood diseases, especially leukemia, has greatly increased. According to statistics, the benzene inhaled by smokers is 10 times higher than that of non-smokers, so the risk of leukaemia of smokers is 6-7 times higher than that of non-smokers; the statistics of children's leukaemia factors in Xinhua Hospital show that more than 60% of children's families with leukaemia have second-hand smoke pollution. It is suggested that smoking plays an important role in the pathogenesis of leukemia.
