The inevitable problem of aging has always been the focus of global attention, and the latest research by the Chinese Academy of Sciences shows that nicotine may become an effective means of preventing aging!
Although people have always associated nicotine intake patterns such as smoking with negative health events in their daily lives, studies have shown that nicotine can fight aging in certain doses and ranges, and it can have a positive effect on physical health.
If people can better understand the positive effects of nicotine and gradually apply it to the field of health and longevity, then this will have a significant impact on human health! Next, we will introduce the research results related to nicotine anti-aging and look forward to its future application in the field of health.
Studies have found that nicotine can be anti-aging, long-term intake or anti-aging, how will it be applied in the future?
I believe that everyone has heard the propaganda since childhood that smoking is harmful to health, and the culprit that causes the harm of smoking is nicotine! However, recently, many people have said that smoking can help delay aging, so is there a scientific basis for this statement?
In this regard, some experts have made a special study, the results show that long-term intake of nicotine can significantly extend the life span of mice, and can slow down the aging phenomena such as lung failure and muscle atrophy in mice due to aging; This suggests that nicotine may have potential anti-aging effects and is expected to become a new anti-aging drug.
Nicotine can inhibit the production of free radicals in a variety of ways, slow down the oxidative damage of cells, and thus achieve the purpose of anti-aging.
In addition, nicotine can also activate human protein kinases, such as SIRT1 and AMPK, which can promote the normal functioning of human metabolites, thereby slowing down the aging of the human body.

Since nicotine has been associated with smoking, lung diseases and other factors in the past, when people think of nicotine, cigarettes may first come to mind.
However, the study group of this experiment is mice, not humans, and the ingredients contained in cigarettes are far from nicotine, and there are many toxic and harmful substances! Smoking and nicotine intake alone to achieve the "anti-aging" mentioned in the study is tantamount to a fantasy.
The benefits of nicotine are less than the sum of the harmful substances in cigarettes! causing the consequences of "living beyond one's means"; Therefore, nicotine is harmful and cannot be a reason for smokers and ex-smokers to indulge themselves.
How much does nicotine hurt people?
Nicotine is mainly found in the vacuoles of tobacco cells, belongs to plants, and is harmful to the human body!
Nicotine is a colorless oily liquid at room temperature, soluble in water, soluble in ethanol, ether, acetone and other organic solvents; The boiling point of nicotine at normal pressure is 248 °C, and the specific gravity is 1.01 at 20 °C, which can escape with water vapor, and its content can be determined by spectrophotometer.
1. Neurological damage
After nicotine enters the human body, it will quickly reach various tissues and organs with blood circulation, and it only takes 7 seconds to penetrate the blood-brain barrier and enter the brain, causing great damage to the central nervous system.
Nicotine is addictive, and after inhalation, it will paralyze the nerves and make people produce short-term pleasure; In addition, after long-term inhalation of cigarettes, it will create physical and psychological dependence, and in severe cases, it can even lead to the appearance of symptoms of memory loss and nervous system disorders.
2. Damage to the digestive system
When the nicotine in cigarettes is burned at high temperature, it will produce a large number of chemical components such as alkaloids, which are toxic to the digestive system of the human body and may cause nausea, vomiting, heartburn, acid reflux and other long-term discomfort symptoms; In addition, relevant studies have shown that the incidence of stomach cancer in perennial smokers has increased significantly!
3. Affect growth and development
Nicotine can induce sympathetic and parasympathetic palsies, which can have many adverse effects on the hormonal system and heart function!
4. Carcinogenicity
Some compounds in cigarettes, such as nicotine, have strong surface adhesion and will chemically react with nitrite in the air to produce highly carcinogenic nitrosamines, so you should pay attention to quitting smoking.
