Xiao Sun learned to smoke at a very early age, and like many people, he was just curious to try it at first, and then he got out of control.
He tried to quit smoking several times, but the process was too uncomfortable for him, and in the end, it didn't work.
A few days ago, Xiao Sun's girlfriend mentioned this matter to him again, and he was a little impatient.
It's not that I haven't tried it, the process of quitting smoking is indeed a little painful, and I suddenly remembered a message I accidentally swiped before, so I said to his girlfriend:
"Don't talk about quitting smoking, I saw an article before, which said that nicotine can delay aging in a study published by the Chinese Academy of Sciences, that doesn't mean that smoking is not harmful to health, but it will be beneficial."
His girlfriend looked at him with shocked eyes and said, "You also believe this kind of thing!" ”
What is the research of the Chinese Academy of Sciences that Xiao Sun said? Is our perception that smoking is harmful to our health false? Has smoking become a good thing to prolong life?
1. The harm of smoking to the body cannot be ignored
The main substances of cigarettes are nicotine, tar, carbon dioxide, etc., which we know to be the main toxic substances.
In fact, there are dozens of harmful chemicals in cigarettes, and this small cigarette has a "large amount".
Most people feel that they don't feel anything at all when they first start smoking, and they may just feel a little uncomfortable in their respiratory tract and choke on the smoke.
After a long time, obvious symptoms such as insomnia and cough will appear, because the degree of erosion of the harmful substances in cigarettes to the body is gradually revealed.
If we talk about the specific injuries, we are most familiar with lung diseases. Because the lungs play the role of filtration and ventilation.
The harmful substances in cigarettes can cause fibrosis in the lungs for a long time, which can affect lung function, and the most serious is lung cancer.
The average smoker may also have a bad heart, and this heart problem will manifest itself as the smoking age increases.
The main reason is that the harmful substances in cigarettes will enter the blood and participate in blood circulation, and the heart, as a blood pumping organ, is very vulnerable to harmful substances.
There are many middle-aged and elderly friends who smoke all year round will feel that they have obvious breathlessness, chest tightness, and shortness of breath, which is likely to be a heart problem caused by smoking.

Compared with non-smokers and smokers, non-smokers have better skin condition and are younger, and it can be said that long-term smoking will also lead to faster aging.
It has been said that the substances in cigarettes will be added to the blood circulation, and these harmful substances will destroy the cells under the skin, so that people are prone to wrinkles, pigmentation, etc., and we will look much older than non-smokers with the naked eye.
Of course, this kind of aging is not only on the skin, but also on the body function, mainly because of the damage to tissues and organs caused by harmful substances.
There is also a more obvious problem of cardiovascular and cerebrovascular diseases.
The effect of a variety of harmful substances in cigarettes on blood vessels is to cause inflammation, damage, and accelerated hardening, which will cause problems such as blockage and rupture of blood vessels, and it is not far from the problems of centrifugal infarction and cerebral infarction in blood vessels.
Generally, the stomach of long-term smokers is not very good, because cigarettes are also harmful to the gastric mucosa. If left unmanaged, it can lead to serious stomach problems, such as gastritis, gastric ulcers, etc.
There is a saying called "tobacco and alcohol are not separated", almost everyone who loves to smoke also likes to drink, which leads to greater damage to the stomach, so the stomach is still in the minority among the people who smoke.
The dangers of cigarettes we know are much more than that. But there is such a study in the Chinese Academy of Sciences, some substances in cigarettes can delay aging, what is going on?
2. The Chinese Academy of Sciences publishes subversive research! Can nicotine slow down aging, is it true or false?
Whenever we talk about cigarettes, we will equate them with nicotine, so we will unconsciously bring in cigarettes when there is research on nicotine.
The conclusion of this study, published in March 2023, was proposed by Li Xiang's team from the Shenzhen Advanced Institute of the Chinese Academy of Sciences, and the conclusion is that "an appropriate amount of nicotine can increase the lifespan of mice." ”
From this conclusion, we can see that the samples used in this experiment are mice, as follows:
The 48 mice were divided into two groups, one group put nicotine in a low dose (2 micrograms) in water, and the other group drank ordinary water, and then underwent observation for 6~12 months.
In this observation, it was found that after the mice entered the old age stage, only half of the mice did not drink water with nicotine, and more than half of the mice that drank low-dose nicotine water were alive.
After the final comparison, it was found that a low intake of nicotine can reverse aging and prolong life by 40%. This is because nicotine improves NAMPT activity and NAD+ synthesis in male mice, further correcting glucose metabolism and cognitive function.
The conclusion of this study has been published and seen by many people, thinking that nicotine can prolong the life of mice by 40%, and the same biological human beings mean that smoking will not have an impact on the health or longevity of the body?
The answer, of course, is no, because in this conclusion it is nicotine and not cigarettes.
We need to make it clear that cigarettes are not the same as nicotine, as mentioned above, the chemical composition of cigarettes is not only nicotine, but also tar, carbon dioxide and other harmful chemicals.
Therefore, the focus is wrong, and in this experiment, it can only be proved that nicotine target mouse organisms do have a life-prolonging effect in the way of low dose ingestion, and it is not known to humans.
Of course, this is not only a problem, if you have to compare nicotine with smoking, there are too many variables.
The concentration of nicotine ingested by human smoking is much higher than that of mice directly drinking, and the concentration of nicotine in the blood is definitely different to the degree of harm to the body.
There are also differences between species and different environments, and the environment in which mice live is controlled by humans, what does this mean?
It means that humans let the mice drink as much as they want, which is completely controllable, and there is no way to do it even if they can't help it.
For self-conscious people, if there is no absolute control, it is difficult to quit after smoking addiction, which also involves the amount and addiction of smoking.
From any point of view, it is impossible to equate smoking with direct nicotine intake.
As a smoker, don't rejoice too soon.
Smoking is harmful to health, which has been proven by many teams in relevant experiments, and there is a lot of data to prove it.
Just as there are many people who have lung cancer, a large part of them have been smoking for a long time, and cigarettes have a very definite damage to the lungs, so that the rate of cancer is accelerated.
Of course, we can't choose to prolong life by ingesting nicotine directly, after all, the human body structure is still very different from that of mice.
Cross-species experiments cannot be absolutely certain that there is no harm to humans without clinical experiments on humans.
In this way, it can be concluded that nicotine only has a certain life-prolonging effect on mice, and it is unknown to humans.
At the same time, it is important to understand that cigarettes are not the same as nicotine, and it is a sure thing that smoking is harmful to health, so smoking will not be the secret of longevity.
So what should you do if you really want to live a long life? Here are the real secrets to longevity.
Third, this is the real secret of longevity
From ancient times to the present, many people have been pursuing longevity, and emperors are inevitably vulgar. For people, there is a certain fear of death, so they will find ways to prolong their lifespan.
The length of life still depends on the quality of life, and if you want to live a real life, you can do the following things.
Have a good sleep schedule. Sleep is a very important thing for people, and the human body has a clear division of labor during the day and night.
During the day, the brain and body are all functioning, and at night, they enter a state of rest and are able to complete self-repair.
Getting enough sleep is the foundation of good health, but many people nowadays, from children to the elderly, suffer from sleep problems.
Some people are reluctant to sleep, while others are unable to sleep, either of which conditions will affect the duration and quality of sleep, thus affecting the foundation of health.
Therefore, it is recommended that if you want to live a long life, you must develop the habit of going to bed early and getting up early. It is recommended to go to sleep at 10:30, even if you wake up a little earlier the next day, it is much better than staying up late.
Exercise to exercise the body. Exercising is also one of the secrets of longevity. Only in the process of continuous exercise can the body's metabolism become faster, which has the effect of preventing aging and prolonging life.
Maintain an optimistic mindset. No matter what age you are, maintaining an optimistic attitude is a good way to keep yourself healthy and healthy, and it also plays a role in maintaining your health. If you have a better mentality and fewer diseases, your body will naturally be healthy and you will be able to prolong your life.
summary
When many people see an article, especially some authoritative publications, they may only look at the conclusions, never look at the process, or the samples used in the research process, which leads people to easily fall into misunderstandings.
The thing used in this study by the Chinese Academy of Sciences is nicotine, not cigarettes. Cigarettes and nicotine are not exactly equated.
It can be said that part of cigarettes is nicotine, and it will also contain other harmful substances, so the harm to the body is greater than that of nicotine alone.
For the research done by the Chinese Academy of Sciences, most people have concluded that cigarettes not only have no harm to the body, but even have the effect of prolonging life.
