Now quit smoking, everything is still too late! 1, addicted to smoking, can not control. What is the addiction to smoking? Smoking addiction is the dependence on cigarettes, mainly as a result of the long-term effects of nicotine. Generally when people first start smoking may cause chest tightness, nausea, dizziness and other discomfort, but if you smoke for a long time, the nicotine in the blood reaches a certain concentration, will repeatedly stimulate the brain and make the organs produce dependence on nicotine. Is it really impossible to control the addiction to smoking? So many people have succeeded in quitting smoking, why you can’t quit it? Ultimately, it is not strong enough willpower, or not deeply aware of the dangers of smoking. Now many hospitals have smoking cessation clinics in the respiratory department, really can’t quit smoking old smokers can move to consult a doctor and seek medical advice. 2, fluke psychology, some people have been smoking and drinking for their whole life body times great. On this point, the medical respiratory channel has published an article “Why do some people smoke for a lifetime but do not get lung cancer? (click to jump), the article says very clearly that long-term smokers, in fact, face the risk of genetic mutation leading to lung cancer at any time, and the risk is getting higher and higher. At this point you may still be holding on to your luck, but if you are found to have lung nodules and lung cancer, can you still take it lightly? Even if you don’t have lung cancer, do you think you can escape from chronic obstructive pulmonary disease, emphysema and breathing difficulties? It’s not too late to quit smoking. Studies have shown that quitting smoking at any time will have health benefits, and the sooner you quit, the better. When smokers choose to quit at different stages of their lives, their cancer risk is reduced to varying degrees. What exactly are the benefits of quitting smoking? When you quit smoking, your lungs repair the damage and heal to some extent. When you quit smoking, some short-term inflammation in the lungs is reversed, the lung and airway surfaces become swollen, and lung cell mucus production is reduced. At the same time new cilia are recreated to better remove mucus secretions. Shortness of breath occurs with exercise in ex-smokers a few days after quitting, and it is not clear why the shortness of breath occurs. After quitting, the airways are no longer exposed to the harmful chemicals produced by cigarettes, so airway inflammation improves. When the airway surface is swollen, the exhaled air can pass through the airway more smoothly. Paradoxically, however, smokers tend to cough more severely in the first few weeks after quitting than they did when they smoked. This is actually a good thing, because it means that the lung cilia are active again, and these cilia can expel excess mucus secretions from the lungs into the airways and throat, and then out of the body. This means that coughing will help with better mucus clearance from the lungs. Quitting smoking may also reduce the risk of lung cancer. As mentioned earlier, although the risk of lung cancer has not completely disappeared, the sooner smokers quit, the lower their risk of developing lung cancer. According to the Centers for Disease Control and Prevention, those who quit smoking for 10 years were half as likely to develop lung cancer as smokers. It is also worth noting that quitters are still more likely to die from lung cancer than nonsmokers. Although the lungs are able to heal to some extent after quitting smoking, not all damage is reversible. Lung damage and the degree of deterioration in lung function are closely related to the total number of cigarettes smoked. The longer you smoke and the more you smoke, the more irreversible the damage becomes. Although the lungs have some self-defense mechanisms, prolonged exposure to the harmful chemicals contained in cigarettes causes inflammation and scarring of the lung tissues, making them inelastic and unable to exchange oxygen effectively. The alveoli, where oxygen and carbon dioxide are exchanged, can be damaged by long-term smoking, which in turn can lead to emphysema. In turn, people with emphysema experience difficulty breathing. Emphysema is one of the processes of slow obstructive pulmonary disease, which can easily develop into pulmonary heart disease if treatment is not intervened. And the most common symptoms of patients with slow-onset lung are shortness of breath and dyspnea. Once a smoker has emphysema, the walls of the airways lose their shape and elasticity, making it difficult to get all the air out of the lungs, and emphysema caused by smoking is permanent and irreversible. Recent scientific studies have shown that respiratory and emphysema-related damage occurs within a few years of a person smoking, although symptoms of emphysema may not appear until 20 or 30 years after smoking.
