There are many people who smoke in life, but it is also known that smoking is harmful to health. It’s just that people don’t know much about the harm of smoking and don’t pay attention to it. Today I will tell you specifically about the harms of smoking. I believe that after understanding it, everyone will stay away from cigarettes.

What are the dangers of smoking?

1. Smoking can easily lead to cardiovascular disease

Smoking can easily lead to cardiovascular diseases. The carbon monoxide in cigarettes will reduce the oxygen in the human blood, which will increase the incidence of related diseases such as high blood pressure. In addition, smoking will also cause the coronary arteries of the human body to constrict, which will cause myocardial infarction when the blood supply is reduced or the blockage is serious. Smoking will also increase the body's adrenaline, which will lead to many common diseases such as diabetes, cardiovascular and cerebrovascular diseases, and stroke.

2. Smoking is harmful to the lungs

When cigarettes burn, they release 38 toxic chemicals, among which carbon monoxide, tar and nicotine are the largest. These substances can cause obvious damage to the human oral cavity, trachea and lungs. The tar it contains will also adsorb on the villi in the human lungs, destroying the function of the villi and increasing the sputum in the human body. Over time, it will turn into a chronic disease, which will significantly increase the incidence of emphysema, tracheitis and cor pulmonale.

3. Smoking can cause cancer

Smoking can also increase the incidence of cancer in humans, because smoking is the fastest way to produce the most free radicals. It is said that every puff of cigarette will produce at least 100,000 free radicals, and free radicals are an important component that causes human cell cancer. Many scientists have confirmed that smokers are more likely to suffer from lung cancer, liver cancer, oral cancer and other malignant diseases. In other words, only by staying away from cigarettes can you stay away from cancer.
