It turns out that there are 5 types of harm caused by smoking

I believe that everyone is familiar with the saying that smoking is harmful to health, even children know it, but few people know what harm smoking does to human health, which has led to the emergence of many smokers. In fact, the harm of smoking to the human body is very huge. It can be summarized in the following 5 points. Let's take a closer look!

1. Lung Disease

When cigarettes burn, they release 38 toxic chemicals, among which the main harmful ingredients are tar, carbon monoxide, nicotine, dioxins and irritating smoke. Tar is harmful to the mouth, throat, trachea and lungs.

The tar in tobacco smoke is deposited on the villi of the lungs, destroying their function, increasing sputum, and causing chronic bronchial lesions, leading to tracheitis, emphysema, cor pulmonale, and lung cancer.

According to statistics, 74% of smokers suffer from lung diseases after the age of 60, while only 4% of non-smokers suffer from lung diseases after the age of 60.

2. Cardiovascular Disease

The carbon monoxide in cigarettes reduces the oxygen content in the blood, causing related diseases such as high blood pressure. Smoking causes coronary artery vasoconstriction, reducing or blocking the supply and causing myocardial infarction.

Smoking can increase adrenaline, causing the heart rate to accelerate, increase the heart load, affect blood circulation and lead to more than 20 diseases such as cardiovascular and cerebrovascular diseases, diabetes, sudden death syndrome, decreased respiratory function and stroke.

3. Smoking causes cancer

Studies have found that smoking is the fastest and most abundant way to produce free radicals. Each puff of cigarette produces at least 100,000 free radicals, which can lead to cancer and many chronic diseases.

Why are many smokers prone to catching colds? This is mainly because the activity of human lymphocytes is reduced, which causes cancer.

4. Smoking can also lead to osteoporosis and early menopause

Smoking can cause men to lose their reproductive and fertility functions. Smoking during pregnancy can lead to premature birth and low birth weight of the fetus, and increase the chance of miscarriage. Smoking yellows teeth and causes bad breath.

Smoking can cause male reproductive and fertility loss

Smoking harms both yourself and others, and people who are exposed to passive smoking suffer five times more harm than smokers. For the health of you and your family, do not let yourself become a slave to smoking and quit smoking as soon as possible.

5. The harm of smoking to intelligence

Smoking can affect a person's concentration. Some people believe that smoking can refresh people, eliminate fatigue and trigger inspiration, which is completely unscientific. Experiments have shown that smoking seriously affects people's intelligence and memory, thereby reducing work and study efficiency.
