How much does smoking a cigarette hurt the 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.

If you are afraid of the bad consequences of accidentally smoking a cigarette, this can be ignored, the harm of a cigarette is far less than the harm of the exhaust gas you smoke from shopping.

But every time I see a sentence, I laugh to death, that is: a day of pooping is equal to smoking three packs of cigarettes...

The harm of smoking a cigarette is to damage lung function, obstruct the cardiovascular system, and cause harm to **.

1.Impaired lung function.

There are often many germs in the air that are invisible to the naked eye, and they enter the nasal cavity with our breath and fall on the mucous membranes of the trachea and bronchi. In order to prevent these "foreign substances" from entering the alveoli, the cilia on the mucous membranes of our respiratory tract need to swing, produce sputum, and cough to expel invading germs from the body.

However, long-term smoking or second-hand smoke will reduce the swing speed of these cilia from 12-15 times per second to less than 10 times, and once the germs cannot be excreted in time, they will cause various inflammation, emphysema and other respiratory diseases.

Smoke contains inflammatory substances that can also damage the alveoli and cause lung damage. Harmful substances such as nitrosamines and benzene in fumes can also directly or indirectly cause cancer.

2.Obstruction of the cardiovascular system.

Studies have shown that smoking a cigarette may increase systolic blood pressure by 10-30 mm Hg. If blood pressure remains high for a long time, other cardiovascular and cerebrovascular diseases will wait for an opportunity to do evil.

After 12 years of research, American cardiovascular doctor Flemingham found that smokers have a more than 4 times higher chance of sudden death from coronary heart disease than non-smokers, and the incidence is proportional to the number of cigarettes smoked per day.

3.**Harm.

The biggest damage to smoking is "disfigurement". It can accelerate aging, atrophy, radial wrinkles at the corners of the eyes and upper and lower lips, and deepening wrinkles on the cheeks. Studies have shown that smoking more than 10 cigarettes a week for more than 10 years will result in a pale orange appearance and bone contours.

Smoking in men accelerates baldness, and female smokers are prone to acne. In addition, smokers also have an increased chance of developing acne and rosacea.
