Harm of alcohol and tobacco to health
1. Tobacco smoke contains hundreds of harmful substances, among which 69 known carcinogens can directly cause oral and pharyngeal malignant tumors, laryngeal cancer, esophageal cancer, gastric cancer, liver cancer, pancreatic cancer, renal cancer, bladder cancer, cervical cancer and other cancers.
2. Smoking can lead to chronic obstructive pulmonary disease and cardiovascular and cerebrovascular diseases, which is one of the main causes of coronary heart disease, stroke, aortic aneurysm and peripheral vascular diseases, and also an independent risk factor for cardiovascular and cerebrovascular diseases.
Second, the harm of alcohol to the body:
1, to the brain
A small amount of wine can make people excited, make the brain active and have a certain calming effect. However, excessive drinking will reduce people's attention and judgment, even lead to slurred speech, blurred vision, loss of balance, and more seriously affect people's memory.
2. For the liver
Old people often say that drinking hurts the liver. It seems that the harm of drinking to the liver should be the most widely known.
3. Brain damage affects learning.
As a psychoactive substance, alcohol will also have a strong stimulating effect on people's heart, brain and blood vessels, and will also have a negative impact on people's nervous system. Even a small amount of drinking is easy to cause some damage to the brain, which can easily lead to mental retardation and other symptoms.
4, the influence of the nerve center
Alcohol is a small molecular substance, which can easily reach all organs of the body. When ethanol enters the body, it will soon enter our brains. It will also do great harm to our nervous system, mainly manifested as uncoordinated muscles, slow response, euphoria, decreased attention, judgment and self-control, decreased memory and decreased intelligence.
5, the influence on the stomach
Alcohol is absorbed in the gastrointestinal tract, which is easy to cause gastric ulcer. Because alcohol stimulates the gastric mucosa and causes gastric mucosal bleeding, it will lead to chronic gastritis, loss of appetite and diarrhea in the long run. Due to long-term loss of appetite, it will also lead to adverse reactions such as anemia.
6. Drinking alcohol is harmful to the heart
Long-term heavy drinking can also cause myocardial fibrosis, loss of elasticity, enlargement of heart, increase of cholesterol, and damage to cardiovascular and cerebrovascular systems. The incidence of myocarditis, arteriosclerosis and coronary heart disease is much higher than that of moderate drinkers.
7. Drinking harms the next generation
Long-term heavy drinking will also affect sperm mobility and reduce fertility. Even if the sperm damaged by alcohol makes the egg pregnant, there is a great chance of giving birth to deformed children with mental retardation or patients with "infant alcohol syndrome".
