Electronic cigarettes are actually through electronic devices to spray effective tobacco ingredients such as nicotine with atomization technology, and then simulate the effect of smoking. According to propaganda, the damage to the human body of electronic cigarettes is about 95%lower than ordinary cigarettes, which is the main reason for many people to choose electronic cigarettes. But on the other hand, many people also question the harm of electronic cigarettes. They believe that the electronic cigarettes have been absorbed more, and there will also be some lung diseases with electronic cigarettes. Is this true?

Electronic cigarettes, is it the "savior" of smokers or the "stars" of smokers?

We might as well look at it from a scientific perspective:

The main working principle of electronic cigarettes is to spray necessary substances such as nicotine through electronic devices. And 69 kinds of carcinogens such as nitrosamine, formaldehyde, and polygon arbiter (A) 芘, which are produced by normal cigarettes during the burning. Electronic cigarettes have no actual combustion effect, so they are not all.

From this comparison, electronic cigarettes are indeed much less harmful than ordinary cigarettes. According to data from the British Ministry of Public Health in 2018, only about 0.4%of ordinary tobacco users' lung cancer in the UK's Ministry of Public Health. From this point of view, compared with ordinary cigarettes, electronic cigarettes are indeed a better choice for smokers.

But some people may still not believe: "Where does the unique lung disease from the electronic cigarette come from?"

Indeed, the American Cancer Association has published a study that believes that the air -soluble and cymbal compounds in electronic cigarettes will also stimulate the lungs and cause special "electronic tobacco and lung disease". The main reason.

But in fact, as early as 2019, the US Centers for Disease Control and Prevention clarified rumors about electronic tobacco and lung disease. Wait for toxic substances, then cause diseases. And in 2020, the United States also withdrawn from "not recommended to use electronic cigarettes".

The above, compared to ordinary cigarettes. Electronic cigarettes can reduce damage and help steadily quit smoking. It is indeed a very good cigarette substitute. However, please don't be anxious to be happy first. If there is no ordinary person with a history of smoking, or friends who can quit smoking with their own ability, don't blindly use electronic cigarettes. You know, electronic cigarettes can "reduce harm", but it does not mean that it is "harmless"!

What kind of damage does electronic cigarette itself cause health?

① Still toxic the body

Compared with ordinary cigarettes, although a large amount of toxic substances such as tars in electronic cigarettes have been removed, there are still certain harmful substances. For those who do not smoke or smoke less As a result, the toxicity of the lungs increases and increases the risk of lung and respiratory diseases. This is the main reason why people other than smokers use electronic cigarettes.

② will cause increased risk of inflammation in the eye

In order to better simulate the smoke of cigarettes, the steam formed by electronic cigarettes will be larger. Long -term absorption of electronic cigarettes, eyes and other fragile positions are stimulated by smoke for a long time, which will become red, dry, and even inflammation and conjunctival damage. risks of.

③ The harm of Nicotine sucking

Nicotine is the main component of electronic cigarettes. While absorbing electronic cigarettes, it will also inhale a large number of nicotine. Although it is less harmful to ordinary cigarettes, nicotine can also cause diseases such as nausea, vomiting, dizziness, and even infertility. Symptoms appear. Please also pay attention.

In fact, another question that makes us worth thinking is why cigarettes are replaced by electronic cigarettes around the world? And electronic cigarettes have also been officially included in cigarette management.

Recently, countries have made deeper progress on the research of nicotine and electronic cigarettes. On the one hand, Li Xiang team of the Shenzhen Academy of Advanced Technology of the Chinese Academy of Sciences revealed the mechanism of nicotine to improve metabolism and delay aging through experiments. New technical direction. On the other hand, the research team of the University of Blagaminho, Portugal, adopted the chick embryo experiment, proved that the dangers of electronic flue gas -solidaries to the development of the lungs and embryos are very small, far lower than that of traditional cigarettes.

Li Xiang team of the Shenzhen Academy of Advanced Technology of the Chinese Academy of Sciences, has been studying Nicotine for a long time. It mainly analyzes the influence of NAD+NAD+(oxidation form of nicotinamide glandular dilate) in the human body. NAD+has a key role in maintaining cell vitality. The global popular anti -aging product NMN, known as the "non -old medicine", reverses aging by improving the intracellular NAD+level.

Recently, Li Xiang's team published on the Nature Communications magazine online entitled "Nicotine Rebalances NAD + Homeostasis and Improves Agging Symptoms in MILE MILE MILE MILE BY Enhancing Nampt Activity.

Li Xiang's team research found that chronic low -dose nicotine can improve energy metabolism and delay systematically aging by activating the NAD + remedy pathway. This view was confirmed in mice experiments. Researchers observe and test the long -term drinking nicotine water of mice for a long time. It is found that nicotine has a positive effect on nerve protection, and can promote the interaction of two proteases in the cells, reduce aging factor levels, and enhance NAD + activity. So as to improve the metabolic speed of aging organizations. In addition, researchers have also found that after nicotine breaks down in mice, it can alleviate mice's anxiety and improve their learning and memory function.

This study of the Chinese team provided new targets and methods for expanding the application of nicotine and anti -aging, and once again confirmed that Nicotine was not harmful. The appropriate amount of nicotine still has a certain positive effect. The current nicotine exists in tobacco, and electronic cigarettes are a new form of nicotine intake.

All in all, the positioning of electronic cigarettes is very complicated. On the one hand, it does have a good effect on reducing and smoking cessation effects on ordinary smokers. But on the other hand, if the non -smokers who are misleaded or blindly contacting electronic cigarettes will indeed cause harm to the body.

Therefore, smokers can try to use electronic cigarettes, but for ordinary people, especially young people involved in the world, do not come into contact! Any thing can really exert its advantages and value only in the right aspect. Even electronic cigarettes are the same.
