Tobacco smoke and damage to the functions of the lungs and bronchi


In addition to its proven carcinogenic effect, regular inhalation of tobacco smoke has a negative impact on the overall condition of the lungs and bronchi. Hot gases, tar, sulfur compounds and other chemicals in tobacco smoke not only irritate but gradually damage the bronchial epithelium, leading to Chronic Obstructive Pulmonary Disease (COPD) in the long term.

The ciliary epithelium is involved in the bronchial cleansing process, helping to remove contaminants that we draw into the lungs with the air. The cilia move in a synchronized way towards the larynx, slowly moving the mucus on them. Due to the constant irritation of the cilia by tobacco smoke, their function is gradually impaired. Contaminated mucus begins to build up in the bronchi, increasing the risk of infections and infections.

In addition, inhalation of tobacco smoke irritates the bronchi, which in turn leads to an overgrowth of the bronchial mucous glands and the secretion of more and more mucus, which irritated cilia are unable to systematically remove. This only aggravates the problem and makes you more likely to get infected. Chronic bronchitis appears, which manifests itself in a characteristic cough and sputum production reflex. Typically, an exacerbation of these symptoms occurs in the morning as soon as you wake up and is known as the smoker’s cough.
