Anonymous users2024-02-06The harm of smoking a cigarette is to damage lung function, obstruct the cardiovascular system, and cause harm to **.
1.Impaired lung function.
There are often many germs in the air that are invisible to the naked eye, and they enter the nasal cavity with our breath and fall on the mucous membranes of the trachea and bronchi. In order to prevent these "foreign substances" from entering the alveoli, the cilia on the mucous membranes of our respiratory tract have to swing to produce phlegm and cough.
and other actions to expel the invading germs from the body.
However, long-term smoking or secondhand smoke.
The oscillation speed of these cilia will be reduced from 12-15 times per second to less than 10 times per second, and once the germs cannot be expelled in time, they will cause various inflammations and emphysema in the lungs.
and other respiratory diseases.
Smoke contains inflammatory substances that can also damage the alveoli and cause lung damage. Harmful substances such as nitrosamines and benzene in fumes can also directly or indirectly cause cancer.
2.Obstruction of the cardiovascular system.
Studies have shown that smoking a cigarette may increase systolic blood pressure by 10-30 mm Hg. Long-term high blood pressure, other cardiovascular and cerebrovascular diseases.
will wait for an opportunity to do evil.
After 12 years of research, American cardiovascular doctor Flemingham found that smokers have a more than 4 times higher chance of sudden death from coronary heart disease than non-smokers, and the incidence is proportional to the number of cigarettes smoked per day.
3.**Harm.
The biggest damage to smoking is "disfigurement". It can accelerate aging, atrophy, radial wrinkles at the corners of the eyes and upper and lower lips, and deepening wrinkles on the cheeks. Studies have shown that smoking more than 10 cigarettes a week for more than 10 years will result in a pale orange appearance and bone contours.
Smoking in men accelerates baldness, and female smokers are prone to acne.
Moreover, smokers suffer from acne.
will also increase the chance of developing rosacea.

Anonymous users2024-02-05Let's take a look at a report first, according to reports, a new study published by the University of London in the United Kingdom found that for non-smokers, occasionally trying to smoke a cigarette is not so "harmless", the "sleeper effect" of this cigarette can last for years, and the likelihood of trying to smoke will be greatly increased in the future.
Researchers at the University College London in the United Kingdom followed 2,000 young people between the ages of 11 and 16 for five years. The study found that after 260 children aged 11 tried smoking a cigarette, 18 percent of them became addicted smokers when they reached the age of 14. And only 7 percent of 11-year-olds who didn't try smoking became addicts after three years.
Researchers have not fully figured out why trying to smoke a cigarette would have such a strong impact.
Jen River Fidel, a researcher at the University of London, said that the results have shown that those who have smoked a cigarette are more likely to become addicted and become smokers in the future, and that there is often a "dormant period" of several years in between, which may be the so-called "sleeper effect", and they are more susceptible to nicotine in the future.
Fidel further explained that the nicotine produced by adolescents when they try to smoke may change parts of the brain's "pathways," which in turn makes them more likely to experience feelings of stress or frustration, and therefore more likely to try smoking again and become smokers. After trying to smoke a cigarette, teens may become more familiar with how to smoke and how to evade family control, which can also help them develop the habit of smoking later in life.
The so-called "sleeper effect" mainly refers to the fact that people are prone to forgetting the transmission due to the time interval, and only retain a vague memory of the content. The "sleeper effect" is an interesting and abnormal phenomenon in the study of attitude change, which refers to a phenomenon in which the persuasion effect does not decrease but increases over time in the process of attitude change. Since Hovland's first naming in 1949, the scope of research on the "sleeper effect" has continued to expand, and the number has continued to increase.

Anonymous users2024-02-01A British study found that smoking only one cigarette a day also increased the risk of heart disease by three times, and the greater the amount of smoking, the longer the smoking age, the greater the risk of cardiovascular disease. Tobacco contains a lot of nicotine, which causes the body's secretion of adrenaline and norepinephrine to increase, causing the heart to beat faster and blood pressure higher; Smoking will lead to vasoconstriction and spasm, increase blood flow resistance, increase blood viscosity, and lead to atherosclerosis of arteries in the heart, brain, kidneys and other organs of the body; Smoking can induce sudden death; Smoking can cause cerebral arteriosclerosis, which can lead to damage to brain cells, affect memory and mental disorders.
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

In addition to releasing a large amount of heat energy, the combustible substances can also produce a large number of toxic and harmful smoke and dust, which carry suspended particles and vapors, and there will be carbon monoxide, carbon dioxide, sulfur dioxide, ammonia, hydrogen sulfide, nitrogen oxides, cyanide and other complex toxic gases according to the different combustibles, which will cause poisoning manifestations ranging from mild to severe after acting on the human body, accompanied by oxygen deficiency. In recent years, the application of a large number of new composite materials has also increased the complexity of smoke composition, which can quickly kill people in serious cases. The smoke formed by the fire is a mixture of a variety of toxic substances, and its harm to the human body is much greater than that of a single toxic gas. >>>More
