How harmful is smoking to the human body? How harmful smoking is to the human body

Smoking is a real health hazard.

Because tobacco contains nicotine (nicotine), it is highly toxic. It has been reported that nicotine in one cigarette can poison 10 mice, nicotine in 25 cigarettes can poison a cow, and 40 60 milligrams of nicotine can kill people. Nicotine damages brain cells, causing central nervous system symptoms in smokers; It causes increased blood pressure, rapid heartbeat, and even arrhythmia and heart disease; Causes stomach pain and other stomach problems; Damage to the bronchial mucosa, causing chronic bronchitis.

More seriously, tobacco dramatically increases the risk of cancer in the lungs, mouth, pharynx, larynx, esophagus, pancreas, bladder and renal pelvis, as well as cancers and leukemia in the nasal cavity, sinuses, stomach, liver, kidneys, cervix. Their danger is determined by how long and how much smokers smoke. For some smokers, alcoholic beverages can also exacerbate the health effects.

However, there is also evidence that smoking does not cause breast cancer and can reduce the frequency of cancer of the uterine wall.

There are no clear results showing the association between smoking and the risk of rectal, colon and prostate cancer.

Some of these types of cancer are more likely to be affected by objects in the smoker's field, smoker drinking, and smoker infection.

Milk can reduce the harm of smoking to the human body.

Smoking is harmful to the body, and this is something that everyone knows. The harm of smoking is: the smoke produced when tobacco is burned contains nicotine, carbon monoxide, tar and other harmful substances, which will harm various organs of the body after inhaling the human body.

In particular, the trachea, lungs, and larynx are more harmed, so many smokers suffer from tracheitis, which is also one of the causes of lung cancer. Some people calculate that each cigarette smoked shortens a person's life by an average of 5 and a half minutes. Of the 7,735 people surveyed by cardiologists in the UK, only 42% of men who smoked at a young age and did not quit lived to the age of 73.

And 78% of men who never smoked lived to be 73 years old.

Drinking milk can reduce the harm of smoking to the human body, because the vitamin A contained in milk has the effect of protecting the wall of the trachea and making it less inflammatory. Vitamin A can maintain the normal development and function of epithelial tissues and mucous membranes. Milk is rich in vitamin B2 is an indispensable substance in the process of respiration and redox in human tissues, tar and benzopyrene in tobacco are one of the most carcinogenic substances, and vitamin B2 can decompose benzopyrene compounds and alleviate the toxicity of tobacco.

Vitamin B12 and vitamin C in milk are beneficial to smokers, so drinking milk has the effect of reducing the harm of smoking.

Experiments by American scientists have proved that smokers who insist on drinking milk every day have a 20% lower proportion of tracheitis than those who smoke and do not drink milk. Therefore, drinking milk can reduce the risk of bronchitis in smokers.

1.Passive smoking in the family has a serious impact on physical health.

2.Over time, there will be many physical problems, such as: chronic laryngitis leads to snoring, which affects the sleep effect and is prone to sudden death caused by cardiovascular and cerebrovascular diseases.

At the same time, it also affects the normal rest of the family and the body is prone to disease. In short, the consequences are very serious, and I have experienced it firsthand. I implore smokers to quit smoking as soon as possible and benefit themselves and others!
