Chapter 1. How smoking affects the health of smokers and others
1.4. How smoking affects the respiratory system

Оглавление

Do not underestimate the influence of smoking on your respiratory system. Chronic lung diseases, bronchitis, and pharynx diseases are frequent companions of smokers. Tobacco smoke, as it passes through the upper respiratory tract, adversely affects the mucous membrane of nasopharynx, bronchi, and trachea, which causes increased salivation and mucus production. The presence of accumulated mucus in the bronchi causes frequent coughing.

Pyridine (a toxic substance found in tobacco smoke) also provokes morning coughing and irritates the mucous membranes of the eyes, tongue, and throat. In combination with other harmful substances, it causes bronchial spasms and increases in the volume and mass of the mucous membranes of the glands that secrete excess sputum. It significantly reduces airway resistance to infections. And since tobacco is not clean-burning, combustion products (soot and tar) enter the respiratory tract. Laryngitis may develop, making your voice hoarse. Chronic bronchitis, pulmonary emphysema, and tracheitis are among the other gruesome diseases caused by smoking. Secondary infection of the respiratory tract due to excess mucus production is more common in smokers.

Last but not least, smoking may cause cancer of the respiratory system. Most deaths from cancer of the larynx and lungs, chronic bronchitis, and emphysema are associated with smoking. I guess everybody knows what the human lungs of a smoker look like. There are a lot of pictures and scary images on this subject on the Internet.

Smoking also decreases the protective function of the ciliated bronchial epithelium, which can lead to the occurrence and development of pulmonary infections. Smokers are more likely than non-smokers to develop tuberculosis disease since harmful substances contained in tobacco smoke change (and not for the better) deteriorated respiratory function. Besides, smoking hinders medical treatment of the disease. Therefore, it might be evident that the lung function of a smoker is impaired, which results in the narrowing of the airways. The respiratory metabolism deteriorates too, which leads to oxygen deficiency. The good news is that if you quit smoking, the impairment of bronchi ceases. If you quit smoking at a young age, you can achieve a complete restoration of lung function. A great bonus of giving up long-term smoking is decreasing of cough and shortness of breath.

Sergey, 40

I do not have a short breath anymore. It disappeared as soon as I quit smoking. Besides, I also got rid of bad breath. My wife is glad that all the money now goes to the family.

Any smoker can quit smoking! FUCK TOBACCO!

☺ Paphnutiy saw “No smoking!” sign in the plane and asked a stewardess for a smokeless cigarette.

F*ck tobacco!
