How harmful is secondhand smoke? Explain it with data! Thank you!!!

Second-hand smoke is really too harmful, even more harmful than people who directly smoke banquet smoke, because second-hand smoke is not only easy to damage children's respiratory system but also may 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 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, it is more damaging to the respiratory system, and children can have symptoms such as cough and sputum. At the same time, after nicotine enters the blood, it spasms small blood vessels, resulting in hardening of the arterioles supplying 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, and enhanced permeability of the blood vessel wall.

In addition, due to the smoking of the surrounding population, exposure to second-hand smoke in childhood, nicotine metabolites will be detected in their 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.

Secondhand smoke, also known as ambient tobacco smoke, includes both mainstream smoke exhaled by smokers and sidestream smoke coming straight out of 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.

If inhaled by other non-smokers, it may also mix with the decay products of radon and cause greater harm to human health. Because your room is not ventilated, the air is not flowing, and it is not fresh, so it is basically smoke, and there are so many of them, the impact must be great, and the harm is also great; It is better to keep air circulation indoors, and place more plants, which have vacuuming, absorb some toxic gases, and discharge fresh air;

Preamble: If you live in a smoky environment, you are a victim of secondhand smoke. Therefore, it is recommended that you must pay attention to your living environment, if the people around you are always smoking, we can also choose to refuse, or you can go outside to breathe.

For us, second-hand smoke is very harmful to our body, even more harmful than direct smoking, so we must take care of our body. If someone is smoking, we can cover our mouth and nose and stay away from them, so as to effectively avoid the harm caused by second-hand smoke to our body.

For many girls, who especially hate men smoking, the same is true. For us, if your partner smokes, we must advise them to quit smoking. We can show them the ** of the lungs after a few years of smoking, and I believe that such a ** will bring them a very big shock.

Then when they smoke, we can also show boredom, we can make them chew gum, which effectively diverts attention. If you don't pay attention to your living environment, then you are vulnerable to second-hand smoke, and you can buy an air purifier, if the air at home is not good, it will also cause great harm to the growth of children.

In daily life, there are many people who like to smoke very much, so I think everyone must learn to stay away. No matter what kind of occasion, as long as you smell smoke, then you must walk away or go to other places as soon as possible, so as to reduce the number of second-hand smoke. So in our daily life, we can choose some foods that have the effect of clearing the lungs, and we must protect our health.

Smoking in public is strictly prohibited, and if it is someone we all know, then we should be able to admonish them. I believe that many people will stop smoking after hearing such words.

Open the window first thing in the morning, wipe the table, and mop the floor to remove tobacco residue from the daily dust. If someone in the house smokes, douse it with water after smoking, or put it in a paper cup with still water, don't go out directly in the ashtray, so that the dust will be sucked into the nasal cavity. Because vitamins have antioxidant functions, they can fight cancer and eliminate smoke from the body as much as possible.

For example, kiwi, oranges, apples, etc. are all good.

A more effective way to avoid secondhand smoke is to avoid people who smoke, and when someone smokes, it is advisable to run to other sides of the fresh air. When there are people smoking indoors, it is recommended to open more windows for ventilation, eat more fresh vegetables and fruits, drink more water, and place plants in the house.

Don't go to places where there are many smokers, open windows for ventilation, and you can also advise others not to smoke, wearing a mask can effectively avoid secondhand smoke.

Don't stay in the same environment as smokers, wear a mask and pay attention to the ventilation of the room to avoid secondhand smoke.

Stay away from smoking places and people, and remind them not to smoke in crowded places when they see smoking in public places.

1.Secondhand smoke can cause severe cardiovascular toxicity: Smoking causes heart disease, not only for those who do smoke, but also for non-smokers who are exposed to secondhand smoke.

It is biologically believed that exposure to secondhand smoke can cause acute coronary heart disease, and that even short-term exposure to secondhand smoke increases the risk of coronary heart disease dramatically. Several components of secondhand smoke can cause severe cardiovascular toxicity, disrupt the normal function of the heart, blood and vascular system, 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 for Excellence in Secondhand Smoke, Pilots Medical Institute, University of California, San FranciscoAccording to Dr. Benowitz, exposure to secondhand smoke inhales the same chemicals as active smoking, and the exposure lasts longer than active smoking. If you smoke a cigarette, you are only exposed to the smoke for 10 minutes; If you sit in a smoky bar, you can be exposed to smoke for hours. Experimental studies have shown that:

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

2.The Dangers of Secondhand Smoke on Memory: Terrence O'Neill and Tom Hefernam, members of the Drug and Alcohol Research Group at Northumbria University, compared the memory of 27 smokers with two groups of nonsmokers.

The first group of non-smokers, consisting of 27 people, regularly inhaled second-hand smoke. They either live under the same roof as the smoker or spend long periods of time with the smoker, such as in designated smoking areas, and are exposed to secondhand smoke for an average of 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 is to ask volunteers to participate in an activity after remembering a specific time, and the other is 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 performed worse, scoring 30% lower than non-smokers who were not regularly exposed to secondhand smoke.

3.The harm of secondhand smoke to pregnant women: 90% of pregnant women who passively smoke secondhand smoke can detect nicotine and other harmful substances in the uterine amniotic fluid, 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, exposure to secondhand smoke has a serious impact on physical health in many ways from the fetal stage. Secondhand smoke exposure also affects the proliferation and differentiation of embryonic cells, resulting in abnormal embryonic development, manifested in developmental disorders of the nervous system and intrauterine growth retardation.
