Anonymous users2024-02-05The reasons are as follows: 1. There is no safety line definition for second-hand smoke. Inhalation of tobacco smoke is harmful to health, and second-hand smoke, although the concentration of smoke is lower than that of direct inhalation of airway smoke, it also reaches the injury domain value.
2. The harmful components of second-hand smoke can exist in the air and dust and the surface of articles for a long time, and are not easy to dissipate. Non-smokers tend to "enjoy" multiple smokers in turn, with long exposures and significant injuries.
3. One person smoking will cause passive smoking by many people in a room. It is important to note that there is no safe level of exposure to secondhand smoke, and even a small amount of exposure for a short period of time can still lead to diseases such as heart attack and asthma attack. Only a total ban on indoor smoking can protect non-smokers from secondhand smoke.

Anonymous users2024-02-04In daily life, smokers are everywhere, and once we inhale second-hand smoke, it is much more harmful than smokers.
Secondhand smoke contains more than 7,000 chemicals, hundreds of which are toxic substances, and about 70 are carcinogenic. There is no minimum harmful dose in secondhand smoke, and once inhaled, it can cause great health effects. In addition to lung cancer in non-smokers, secondhand smoke can also significantly increase the risk of heart attack
Among non-smokers, secondhand smoke causes nearly 34,000 heart disease deaths each year.
Surrounded by second-hand smoke, the most pitiful are children with poor ability to avoid and discourage smoking, according to statistics40% of children between the ages of three and eleven are exposed to secondhand smoke.
How many of them are caused by their own parents, I think many parents should reflect on it。Of course, in daily life, in addition to the second-hand smoke created by parents, you will also get the harm of second-hand smoke from others, and as long as you go out, you will have the opportunity to inhale second-hand smoke. Although many cities have issued local regulations prohibiting smoking in public places, there are still many people who ignore the "ban on smoking" and many people still ignore it.
Even in public places, light a cigarette.
Anyway, others can't persuade their family members to be kind to persuade them, and you can let them smoke less cigarettes first. The main thing is to distract them from the quarrel, which can be replaced by exercise. Just find something else to have fun with.

Anonymous users2024-02-02Exposure to secondhand smoke (passive smoking) is the same as the harm to a person who smokes. The harmful gases in the respiratory tract are similar in the same room. Why is secondhand smoke more harmful?
First, mentally, the smoker is enjoying it, and the person you don't like to smoke hates the smell, forcing you to breathe in disgusting smoke is a harm, and you may feel suffocated, want to vomit and other adverse reactions.
Second, physiologically speaking, people who smoke for a long time have a certain amount of resistance, while you don't, so you belong to a sensitive group, and your reaction to the smell of smoke is more obvious and you are vulnerable.
Thirdly, from the perspective of harming many people, first-hand smoke hurts himself, and spit out second-hand smoke hurts a group of people, especially pregnant women, the elderly, children or people with heart and lung problems.

Anonymous users2024-02-011.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.
<> pet dogs Dog owners who like to smoke should note that smoking is not only harmful to the health of others, but also harmful to the dogs in the family. A number of recent veterinary studies in the United States have confirmed that secondhand smoke can greatly increase the risk of cancer in domestic pets such as cats and dogs. Veterinarians explain that it is because they have a habit of licking their hair, which licks the tobacco carcinogens that accumulate on their hair from the air into their mouths. >>>More
Secondhand smoke is harmful, but not more harmful than smokers. The reason is very simple, the smoker will smoke such as the abdominal cavity after passing through the mouth, trachea, lung lobes and then in turn through the lung lobes, trachea, oral and nasal cavity exhalation, there are some tobacco substances, including harmful substances have been retained by the smoker, that is to say, the harmful substances of a puff of smoke have been stored in the smoker's body, the harmful substances in the smoke exhaled by the smoker are relatively reduced, because the smoker and the second-hand smoker are in this environment, the second-hand smoker is breathing, the smoker also has to breathe, Therefore, smokers themselves are both active smokers and second-hand smokers, and the poison they suffer can only be greater than that of second-hand smokers, and it is not scientific to say that second-hand smokers are more harmful than active smokers. Second-hand smokers are innocent victims, but never more than active smokers. >>>More
