introduction
Everyone must have heard the saying that "smoking is bad for your health".
This slogan can be seen almost everywhere, and it is even printed on cigarette packs, which is really deeply rooted in the hearts of the people, and has instilled in us the impression that smoking is not good since childhood.
However, some experts have found that nicotine, the so-called "most toxic" substance in cigarettes, can reduce the mortality rate by 40%? It really shocked everyone's jaws.
So is nicotine a good medicine for slowing down mortality or a health killer, and does this finding mean that smoking is actually not as dangerous as everyone thinks?
Can nicotine reduce mortality by 30%? Really fake
In the public's impression, nicotine is the most toxic substance in cigarettes, in fact, most of the harm brought by cigarettes to the human body does come from the toxicity of nicotine, and even smokers are addicted to cigarettes because of its existence.
In this way, nicotine is indeed the main culprit of endangering public health, and in fact, it is also true.
Nicotine invades the human body faster than we think, it can enter the human body very quickly and take action, and then directly act on the smoker's brain, so that the smoker is in a "fluttering" feeling, and the feeling is more sensitive, many people will feel very relaxed or refreshed after smoking.
In addition, nicotine can also affect the constriction of blood vessels, when people smoke, blood pressure will be higher than usual, and the heartbeat will continue to increase, and the health of blood vessels will be greatly affected in the long run, and even myocardial infarction can be induced in severe cases, which is really very dangerous.
So why does nicotine, which seems so toxic, reduce mortality by 40%?
As we all know, the research of the Chinese Academy of Sciences involves all aspects, and the achievements made every year are also jaw-dropping, and the Chinese Academy of Sciences has also made major discoveries when it studies nicotine in cigarettes, and this discovery is also shocking!
After a systematic analysis of the data from the nicotine study, the results were very surprising, because the results of the study found that nicotine seems to have a certain protective effect on neurons, it slows down the aging process of neurons, so that the incidence of certain diseases may be greatly reduced!
This result is very surprising, after all, this is a big gap with the nicotine we usually know, but after careful research by researchers from the Chinese Academy of Sciences, it is indeed no problem, and it has also come to the astonishing conclusion that nicotine can reduce the mortality rate by about 40%.
However, after careful review of the data, it will be found that in fact, the Chinese Academy of Sciences has studied nicotine, and it is not the first time to come to such a conclusion, as early as a few years ago, foreign scholars have found that low-dose nicotine can delay the aging of mice by enhancing the activity of a certain substance, and has played a certain positive role in the health of mice.
However, the Chinese Academy of Sciences has also discussed the results of such a study, and has also triggered the active participation of many people, after all, this discovery is still very significant, although nicotine can inhibit a protein complex called mTORC1, thereby delaying aging and oxidation, but the harm of nicotine is still unavoidable.
And this characteristic of nicotine is still based on small animals as experimental objects when we study, this study is still further researched, and needs to be analyzed according to various data of the human body, and this reason can not be used to wash cigarettes, smoking to health is undoubted.
In fact, although nicotine, the main ingredient in cigarettes, has a certain positive effect on certain diseases, it cannot be ignored to bring more serious negative effects, such as addiction, affecting the cardiovascular system, and so on......
No matter from any point of view, smoking is the main culprit of health hazards, even if nicotine is not as toxic as we think, but the harm of cigarettes and other harmful substances cannot be ignored, which is not washed.
The health killer in cigarettes
What we don't know is that a small cigarette can contain hundreds of toxic substances, which can be said to be a "poisonous smoke".
So what about those substances that pose a great danger to our health in addition to nicotine?
Tar must not be unfamiliar to everyone, he is the black smoke after the cigarette is lit, in the form of fine particles in the smoke.
Don't look at it as not aggressive, and even disappear quickly, but it is the main cause of lung cancer and laryngeal cancer, and the degree of toxicity can be imagined, it is simply more terrifying than nicotine.
When smoking, a large amount of carbon monoxide will also be released, carbon monoxide gas is colorless and odorless, is the product of incomplete combustion of carbon, the same, but do not underestimate its toxicity, because carbon monoxide will kill if it smells for a long time, although it is colorless and odorless, but after inhalation, it can greatly stimulate the mucous membrane, damage the respiratory tract, and even poison people in serious cases, causing casualties.
In recent years, there have been many stories about carbon monoxide poisoning causing the death of a family, but the protagonist of the story is hiding in the cigarette cigarette, which has to be guarded against.
Aromatic amines are a very special chemical, and the aromatic amines in tobacco smoke are even common carcinogens, which pose a fatal risk to the lives of smokers.
There are more aromatic amines in tobacco smoke than we think, such as 2-naphthylamine, 4-aminobiphenyls, etc., which are very scary carcinogens, and you can imagine how much impact it has on our health if we smoke for a long time.
In addition to the harmful substances mentioned above, tobacco also contains a lot of substances that pose a threat to our health, such as arsenic, mercury, cadmium, etc., which are very common toxic substances and can even be life-threatening if inhaled for a long time, which is very fatal.
Finally, remind everyone that smoking is harmful to health, especially minors, and smoking must be prohibited.
