What are the effects of smoking on the lungs?

We all know that smoking is harmful to health. This is just an abstract description in language. So what effects does smoking have on the lungs?

Let’s look at a picture first

From this picture, we can clearly see that the lungs of non-smokers are red and spotless, while the lungs of smokers are like ink and dry like black carbon.

The smoke produced by burning cigarettes contains at least thousands of harmful components. The tar and other compounds in it work together on the lungs, eventually causing the smoker’s lungs to turn black.

It can be said that smoking is “a hundred harms without any benefit” to human beings. Tobacco has caused all kinds of negative effects on our bodies. Let me summarize the eight major harms:

1. Affects bone health

Studies have pointed out that if you smoke for a long time, bone density will decrease, and the longer you smoke, the more bone density will decrease, which will increase the chance of osteoporosis.

2. Affect skin health

If you smoke every day, your skin health will be greatly damaged, and the incidence of psoriasis will be much higher. Especially people who smoke more than one pack a day are more likely to suffer from psoriasis .

3. Affect sleep quality

During sleep, the brains of smokers are also more active than other people. They have difficulty falling asleep deeply and have poor sleep quality. Some smokers will get up until midnight to smoke a cigarette. This will undoubtedly affect their sleep and cause damage to their health. .

4. Affect lung health

Smoking will damage the capillaries in the lungs and weaken the immune function of the lungs. This makes smokers prone to lung diseases such as chronic bronchitis . People who smoke for a long time may also develop lung cancer.

5. Impact on sexual function

Smoking will have adverse effects on human blood circulation. As a result, the blood supply to male sexual organs will be reduced, which will easily affect sexual desire. Some men’s impotence is closely related to smoking.

6. Affect fertility

Sperm will react to the nicotine contained in cigarettes to a certain extent, and the fertilization ability of sperm will be weakened because men smoke. In this way, male reproductive function will be damaged.

7. Affect family harmony

Because smoking will cause family members to smoke second-hand and third-hand smoke, even if the family does not smoke, they will be harmed, especially if there are children at home. Smoking can easily cause family conflicts and affect family harmony.

8. Affect personal image

Having straight and whitened teeth can obviously improve your personal image. People who smoke often have their teeth turn yellow and black, and their personal image will be greatly damaged.

Tobacco smoke contains 69 known carcinogens. These carcinogens can cause key gene mutations in the body, disorder the normal growth control mechanism, and ultimately lead to cell canceration and malignant tumors. On this basis, smoking can cause respiratory diseases, damage vascular endothelial function, lead to cardiovascular disease, type 2 diabetes , and increase the risk of macrovascular and microvascular complications in diabetic patients.

It is worth noting that the above hazards are not only for smokers, non-smokers who have been polluted by second-hand and third-hand smoke for a long time will also have the same health risks.

However, once a smoker chooses to quit smoking, the damage caused to the blood, respiratory system, sense of smell, etc. will gradually be alleviated or even begin to recover within three months of quitting smoking. The longer the smoking cessation lasts, the higher the risk of previous heart disease and stroke. Risks are also significantly reduced.

Therefore, no matter from which perspective, quitting smoking will do “a hundred harms but no good” to yourself and the people around you.

So, the question is, after quitting smoking, can the lungs be clean again? If smokers quit smoking early, can the lungs be clean again and be healthy again?

First of all, unfortunately, although the lungs can recover their functions after quitting smoking, they cannot completely return to their original state.

However, after quitting smoking, the inflammation in the lungs will be reduced, and the lung cilia will start to work again, resume their cleaning function, and begin to repair themselves.

Seven days after quitting smoking, the cilia in the lungs can regenerate. Three months after quitting smoking, the cilia return to their normal state and can clean up necrotic cells and repair damaged tissues. One year after quitting smoking, lung function will gradually increase

Research from the American Lung Health Association shows that 10 years after quitting smoking, the risk of lung cancer for ex-smokers is 50% lower than for people who still smoke. So it is certain that quitting smoking can indeed restore normal lung function.

I will also publish an article in the future, specifically talking about the harm of smoking to our cardiovascular system, tips for quitting smoking, and how to save it. I am

Nonsense way of health, for the health of ourselves and those around us, please stay away from cigarettes from now on.
