For many, cigarettes are what the day begins with and what you cannot live without. From school, they inspire us,
that smoking and its effects on human health are extremely negative. However, for some reason, few people listen to these words. But in vain! Almost all organs and systems suffer from nicotine.
What harm does smoking do?
Let us consider in detail smoking and its effect on human health. It is immediately worth noting that the negative impact affects many systems and organs. Let us dwell on each case.
1. Respiratory organs. The resins contained in cigarette smoke enter the bronchi and cause their spasm. In addition, hypertrophy of the mucous membranes occurs, due to which sputum begins to form. As a result, the resistance of the respiratory system to infections is reduced, respiratory diseases occur more often. And also some decay products settle in the lungs, so the functioning of this organ is disrupted, chronic diseases develop.
2. The digestive system. Yes, the effect of smoking on human health extends to it. Nicotine and tar enter the esophagus and stomach. When smoke is in the mouth, the salivary glands become irritated and begin to work intensely, releasing saliva, which a person is forced to constantly spit. Nicotine is able to affect the contractile activity of the stomach and increase the acidity of gastric juice. Because of this, appetite is reduced, nausea occurs, gastritis or an ulcer develops.
3. The effect of smoking on health negatively affects the cardiovascular system. In particular, vessels under the influence of certain substances contract and begin to gradually narrow. Blood circulation worsens, the heart works almost for wear. The pulse quickens, and the pressure often rises. There is a risk of a blood clot, which can come off and rush into the lungs or heart. It is life threatening!
4. Consider smoking and its effect on human health using the example of the musculoskeletal system. The fact is that the substances contained in cigarettes affect bone tissue, making it weak and prone to degenerative processes. Because of this, the risk of fractures increases, and the process of bone fusion is slowed down.
5. The teeth. Smoke is located in the oral cavity, its components settle on the gums and teeth. A plaque forms, a yellowish tint appears. Gums weaken, teeth decay. Caries is inevitable.
6. The process of exchange of carbon dioxide is disrupted, which makes it difficult to access oxygen to almost all organs and tissues. As a result, all important systems of the body cease to function normally, health and general condition deteriorate.
7. Nicotine has a direct effect on the nervous system and brain. Neurons are annoyed, which makes a person nervous and anxious. Brain activity is impaired: memory worsens, concentration suffers.
8. Smoking and its effect on human health is reflected in the condition of the eyes. Vision is deteriorating, the world around is losing its clarity.
9. The genital area also suffers. Libido is greatly reduced. Male potency is also affected.
10. Nicotine and tar affect hormones and metabolic processes.
Stop smoking until your health has completely deteriorated!
