Why does smoking affect lung capacity? Does smoking affect lung capacity?

It's because smoking damages the cells in the lungs and makes them shrink, while tar and some toxic substances attach to the lungs, making it relatively difficult for them to work.

But reducing lung capacity is a certainty.

The dangers of smoking.

1.Cardiovascular disease: Smoking is associated with coronary heart disease, hypertension, sudden death, and the onset of thromboangiitis obliterans.

2.Respiratory diseases: chronic bronchitis, emphysema, COPD and lung cancer.

3.Diseases of the digestive system: peptic ulcer, gastritis, esophageal cancer, colon lesions, pancreatic cancer and gastric cancer.

4.Cerebrovascular diseases: smoking increases the risk of cerebral hemorrhage, cerebral infarction, subarachnoid hemorrhage. In addition, smoking can damage brain cells, damage memory, affect thinking and cause mental disorders.

5.Endocrine diseases: Smoking for 20 cigarettes a day can double the risk of diabetes. Smoking also contributes to thyroid disease.

6.Oral diseases: such as lip cancer, oral cancer, oral leukoplakia, Candida albicans infection, oral mucosal pigmentation, oral odor, etc.

7.Ophthalmic diseases mainly include: toxic optic neuropathy, visual adaptability, macular degeneration, cataract, etc.

Contains a large amount of nicotine, tar and other harmful substances.

Generally, smoking does not affect lung capacity, and if it causes emphysema, it will seriously affect lung capacity. Three months after heavy smoking stopped, the average lung capacity increased by 39%, the shortness of breath decreased, and the skin tone improved.

Cigarette smoking is the main cause of chronic obstructive tracheal disease. Because smoking can cause shortening and irregularity of the cilia of bronchial epithelial cells and impaired motility, reduce local resistance, and susceptibility to infection.

Smoking can also cause emphysema, in which toxic substances accumulate in the bronchial tubes of the lungs, which can hinder the normal exhalation of inhaled air, causing lung cells to swell or burst, making it difficult for people to breathe.

Tips to improve lung capacity:

1. Exercise can increase the lung capacity of Zhixiao.

When a person is in good health, the sound will also be the best. Even simple walking exercises can improve physical fitness, and the effects can extend to the respiratory system and even the vocal domain.

2. Sing loudly.

The health benefits of singing aloud should not be underestimated, and it is recommended to sing along to the radio, join a choir, or sing karaoke.

3. Practice storytelling.

Aaron Johnson, an assistant professor of phonetic science at the University of Illinois in the United States, believes that reading aloud is essential for exercising lung capacity. It is advisable to read aloud an article from the newspaper every day after waking up.

4. Use a straw to do fun vocal exercises.

Like the muscles in other parts of the body, the respiratory system needs exercise to stay healthy. There's an easy way to exercise your vocal cords and respiratory socks at the same time. Put a straw in your mouth and hum vigorously.

Factors affecting lung capacity include: age, gender, stature, strength of respiratory muscles, and elasticity of the lungs and thoracic cage.

Generally speaking, the stronger the body, the greater the lung capacity, which is often used as an indicator to evaluate human fitness.

The lung capacity of an adult male is about 3500 ml and that of a woman is about 2500 ml. Lung capacity is greatest in the prime of life, and smaller in young and older people. The better the health of the person, the greater the lung capacity, and the damage to the lung tissue can reduce the lung capacity.

Thus, a marked decrease in vital capacity is a sign of restrictive ventilation disorder.

What is lost, and the person will die immediately? People die faster without oxygen than with water or food, leaving them for 1 minute and going into shock, leaving them for 5 minutes and damaging their brains, and 10 minutes away and most people dying. Therefore, keeping the body full of oxygen is a way to reduce the aging and death of cells, and lung capacity is very important.

What exactly is lung capacity?

Lung capacity refers to the total amount of gas that is exhaled after a full inhalation, and the lung capacity of an adult man is about 3400 ml, and the lung capacity of a woman is 3100 ml. The amount of normal breathing we normally take is only about 1,000 ml.

Although in ordinary life, ordinary people do not breathe hard and deeply all the time, so the lung capacity used is only about 2 3 percent, but the lung capacity represents the body's reserve gas exchange capacity; When encountering rapid consumption of oxygen such as exercise, people with good lung capacity can also inhale enough oxygen to meet the needs of the whole body, and at the same time discharge the carbon dioxide produced to avoid hypoxia or lactic acid poison caused by excessive carbon dioxide.

If the lung capacity is poor, the muscles that represent the lungs and the diaphragmatic muscles that assist in breathing are also deteriorating, just like the arms and thighs will begin to loosen and weaken after not exercising, and even daily life is very difficult, becoming sarcopenia; If you don't train enough, your breathing muscles will deteriorate, and you may even be wheezing when you climb stairs, and you may feel tired even when you turn around and put on clothes.

How to see if your lung capacity is good.

As mentioned above, the lung capacity in ordinary life is only used to 2 or 3 percent, so even if the lung capacity has degenerated, you will not notice it at first. If there is any abnormality, it is recommended to go to the Department of Thoracic Medicine to find out the real cause.

A trick of breathing is simply to detect lung capacity.

Take a full breath and then hold your breath to see how long you can hold your breath.

Because lung capacity represents the ability of the lungs to carry out gas exchange, if you take a full breath but cannot hold your breath for more than 30 seconds, it means that the amount of oxygen inhaled is too small; Normally, healthy adults should be able to hold their breath for 1 minute, if it is less than 10 seconds, it means that the lung capacity is really too poor, and there may be some lung diseases, or other disease problems.

Take a regular round balloon and exhale vigorously into it until all the air is gone. Watch how long you exhale, and how big the balloon is.
