Harm of tobacco leaves to human body
Effect of tobacco on brain: Nicotine spreads to the whole body through lung mucosa and oral mucosa. After nicotine enters the brain, it can imitate the role of neurotransmitter acetylcholine and combine with nicotine receptors on many neurons. Nicotine can stimulate the central nervous system, especially in the reward circuit. It can release more dopamine by activating related nerves. The harmine and norepinephrine contained in tobacco can keep dopamine, serotonin and norepinephrine in synapses at a high concentration by decomposing the activity of enzymes. With the strengthening of dopamine, serotonin and norepinephrine, people will be more awake and more focused, thus alleviating anxiety and enduring hunger. Tobacco can cause nausea, dizziness and headache.

Tolerance and dependence: Regular smoking can keep the nicotine content in the brain at a high level. Neuron receptors are less and less sensitive to nicotine, and their stimulating effect on dopamine release is also weakened. The original cigarette consumption can no longer satisfy the pleasure of smokers, and smokers are tolerant of nicotine. When smokers stop smoking for a few hours (sleep time), the nicotine content in the body drops and the neuron receptors become extremely sensitive. At this time, the activity of acetylcholine exceeds the normal level, which makes smokers become irritable and want to smoke. At this time, smoking will over-stimulate neuronal receptors and promote the release of dopamine in large quantities. Through this phenomenon, we can understand why the first cigarette every day can bring great pleasure to "old smokers", and smokers are therefore caught in a vicious circle of more and more addiction.

The first ambassador who used tobacco as medicine-1560 When tobacco was not popular, Jean Nico, the French ambassador to Portugal, sent tobacco back to China as a medicine for treating many diseases. Hundreds of years later, chemists finally revealed that the misused drug in tobacco was harmful and named it nicotine.

For centuries, under the influence of "smoke culture" and with the development of modern civilization, "smoke" seems to be one of the symbols of men's charm. With the advancement of industrial civilization, the pressure of material civilization is increasing. Many women are also eager to "smoke". People seem to find a little relief in "smoke" When they realize that "smoke" is very harmful, they also know that it is devouring our health step by step, but they can't get rid of its temptation. The number of smokers in China is 350 million, ranking first in the world.

At present, the smoking cessation products on the market can't really solve the problem of smoking cessation. People always quit smoking and relapse. There are more than 2540 kinds of components in cigarettes, and complex physical and chemical changes will occur after burning. There are more than 400 carcinogens and 65,438+00 substances that can promote the development of cancer, among which nicotine, tar, carbon monoxide, cyanide and polonium -38 are the most harmful to human body.

The concept of smoke

Terms such as "cigarette" and "tobacco" existed in ancient China, but they are quite different from "tobacco" in the modern sense. China's earliest dictionary, Shuowen, has "smoke, internal heat" in the first ten volumes. The original meaning of smoke is internal heat, which is the gas produced when an article burns. From this, many related words are produced, such as smoke, haze, fireworks, smoke waves, smoke willows, smoke clouds and so on. After tobacco was introduced into China, China people gradually called it tobacco. In modern times, opium is often called smoke, and there are words such as opium and smoky soil.

Ignorance is the greatest harm of smoking.

No matter the president or the people, aristocrats or civilians, generals or soldiers, as long as you have this hobby of smoking, you are one of the 654.38+03 billion smokers in the world.

There are/kloc-0.3 billion smokers in the world. They all have the same hobbies in living habits, but they have different results in health and life. Some people smoke all their lives, live to be old and smoke all their lives. Some people died of cancer caused by smoking in middle age; Some people have smoked 100 years, and finally they have no chance to get rid of cancer.

When we are smoking and enjoying ourselves, do you know whether the way you smoke is right or wrong?

China is a big producer of flue-cured tobacco, and 80% of smokers smoke flue-cured tobacco. Compared with blended cigarettes, flue-cured cigarettes have higher tar content and more harmful substances. Especially some high-grade flue-cured cigarettes have higher tar content and greater toxicity than ordinary flue-cured cigarettes.

Many smokers have a habit of picking up a cigarette and observing the color of cut tobacco to see if it is golden yellow, so as to judge the quality of cigarette products. In fact, the color of cut tobacco has little to do with the intrinsic quality of cigarettes. On the contrary, the color of cut tobacco is directly related to tar content and toxicity.

Smokers' chronic tracheitis, emphysema, cor pulmonale and even cancer are all directly related to long-term smoking in the state of water imbalance! Water is the source of life and the foundation of human body, and water is the natural nemesis of tar. Water can excrete most harmful substances produced during smoking through urethra. When the water in the human body is out of balance, many organs such as heart, lung, spleen, liver and kidney can't function normally. After getting up in the morning, sweating, exercising or thirsty, the body's water has lost its balance. At this time, the first demand of the body is hydration! Not smoking!

Therefore, healthy smoking requires smokers to smoke while maintaining the water balance of human body, and develop the habit of drinking water before smoking.

Smoking one cigarette after another is a bad smoking habit, which is no less harmful to human health than overeating. Our investigation found that most smokers who have the habit of joint smoking smoke flue-cured tobacco. In fact, for smokers, the best way to reduce smoking is to switch to stronger tobacco products. Generally, the physiological intensity of mixed tobacco is higher than flue-cured tobacco, and cigars are higher than mixed tobacco. Smokers' smoking frequency and smoking intensity can be automatically adjusted by smoking stronger tobacco products, so as to achieve the purpose of reducing their smoking.

From the point of view of healthy smoking, smokers can change cigarette brands and adjust tobacco varieties regularly, which can greatly reduce the harm of smoking to human body. According to our investigation, up to now, none of the technicians engaged in tobacco science and technology, quality management and process formulation in the world died of cancer because of smoking! This is directly related to their long-term smoking of different tobacco products! Modern scientific research has proved that diet diversification can effectively prevent many diseases. On the contrary, people with partial eclipse have a high probability of getting sick. Smoking is the same as eating. If you smoke a brand for a long time, your ability to detoxify the brand will gradually decrease, which will eventually lead to the occurrence of diseases. Therefore, for your health and longevity, you should choose at least two cigarette brands to smoke together or change cigarette brands every six months.

The human body is a natural tobacco regulator. Reasonable diet adjustment, eat less foods with high fat, eat more fresh vegetables and fruits, and eat more iron-rich soybeans, egg yolks, milk and so on. It can supplement the loss and reduction of vitamin C and antioxidants caused by smoking, eliminate excess oxygen free radicals in the body, help coordinate the generation and elimination of free radicals in the body, and maintain good health.

As we all know, everything in nature is interrelated, and our food culture and tea culture are the essence of nature, extensive and profound. Drinking tea can reduce the harm of smoking, because tea polyphenols, vitamin C and other components in tea can degrade harmful substances in cigarettes. Smoking while drinking tea, toxins can be released continuously with drinking tea, and green tea has anti-cancer effect. If you drink 6 cups of green tea every day, you can reduce the possibility of getting cancer. Therefore, smokers drinking green tea can help reduce the incidence of cancer.

Quit smoking scientifically

The word "addiction" is interpreted as "accumulated hobby" in Ci Yuan. According to the etymological explanation, addicts emerge one after another in modern society! Besides smoking addiction, there are gambling addiction and alcohol addiction. In the past two years, there have been new addicts on the internet, which is the internet addiction that many parents hate! People often use "teetotalless" to describe people who don't drink. If abstinence is abstinence, what's the point? Because modern medicine has proved that moderate drinking is good for health! Therefore, what we want to quit is alcohol addiction, not alcohol!

We say that quitting smoking is for addiction, not for smoking, which means that people have omitted the word "addiction" behind quitting smoking for a long time, and the definition and standard of quitting smoking have become not to smoke a cigarette, not to touch a cigarette! This is the mistake of confusing tobacco with poisonous snakes for a long time! The difference between a word and a thousand miles has attracted countless "smokers" to bend over!

The difference in people's understanding has brought an insurmountable gap to people who quit smoking. Few people really skip it. How many hot-blooded men bravely walked into the misunderstanding of quitting smoking before quitting smoking, and swore to heaven that they would throw all their beloved items and the remaining cigarettes into the trash can, and finally they would smoke cigarettes. Smokers are mostly losers before quitting smoking! Quitting smoking is for health and longevity, but the method of quitting smoking is wrong, and the result will be counterproductive! . According to our investigation, people who quit smoking rarely live long! Why? This is the wrong way to quit smoking.

Some of our parents tried their best to smash the computer, disconnect the internet cable and follow them in order to get their children to quit Internet addiction, but to no avail. As a result, the child ran away from home and you have to go to the internet cafe to find him! Why? Because surfing the internet and internet addiction are two different things! What you want to quit is your child's internet addiction! But what you have done is depriving children of the right to surf the Internet.

Among smokers, we know that some people smoke, but they are not addicted. They quit smoking in the traditional way, but they quit smoking! Does this sound incredible?

Yes! This is "there is no silver here for 320". What do you quit smoking for? So we say quitting smoking is addictive, not smoking. You can't quit smoking without smoking addiction! If you want to quit smoking, you must first determine whether you are addicted to smoking, get out of the misunderstanding of quitting smoking, quit smoking first and then quit smoking. As long as you give up smoking, you are successful! It's not too late to quit smoking after three years!

The process of quitting smoking is the beginning of your smoking! In turn, recalling your smoking process is the best process for you to quit smoking! As the saying goes, "it's easier to get on a thief's boat than to get off it." Any habit is a kind of reflective behavior, and how deep the habit of behavior is, there is more reflection.

The process of quitting smoking is a great adjustment to your spirit, body and mind. How many days does it take to form a habit? It takes the same time to get rid of it! If it took you six months to start smoking and get addicted, it will take you six months to quit smoking now! When I first started smoking, I never smoked, 1 cigarette, 2 cigarettes, 3 cigarettes step by step, and bought cigarettes with others'. Finally, I was promoted to "heavy smoker".

The correct way to quit smoking is to reverse the process of starting smoking, that is, from "heavy smoker" to 3 cigarettes, 2 cigarettes, 1 cigarette, and gradually reduce until you quit smoking.

Everyone says: smoking or not, life expectancy will be long or short, but it is common to live long without smoking, and it is a special case?
