1. Smoking will do great harm to teenagers' health.
1, affecting respiratory tract. If teenagers have the habit of smoking, it will affect the respiratory tract, thus suffering from emphysema, chronic bronchitis and other diseases. It leads to symptoms such as cough, expectoration, dyspnea, and even mild pulmonary dysfunction.
2, affecting cardiovascular and cerebrovascular diseases. Smoking will directly affect cardiovascular and cerebrovascular diseases, because in the process of smoking, harmful substances such as nicotine and carbon monoxide in smoke will damage vascular endothelial cells, which will lead to contraction of peripheral blood vessels and coronary arteries of teenagers, thus causing myocardial hypoxia, which is not conducive to the healthy growth of teenagers.
3, affecting lung development. Smoking will seriously affect the development of the lungs. Because there is a lot of dust in the smoke, and it also contains nicotine, all these substances will remain in the lungs, and it is difficult for the lungs to clean themselves. These harmful substances will be metabolized for many years before they can be completely clean. Smoking among teenagers will affect lung development, and even lead to lung development disorder and asthma.
4. Affect intelligence. A lot of smoke will be produced during smoking, and the content of nitric oxide in the smoke is very high. When teenagers inhale these chemicals, they will form carboxyhemoglobin, which will affect their intelligence.
5. Affect cognitive ability. Because nicotine in tobacco can paralyze nerves, if teenagers' nerves are paralyzed by these substances for a long time, their cognitive ability will be obviously reduced and their learning ability will be weakened.
6. Destroy immunity. Smoking will also affect the whole physical fitness, thus destroying the physical immunity of teenagers and causing them to get sick frequently.
7, affecting vision. Smoking tends to increase the source of fibrin, increase platelet agglutination, decrease high density lipoprotein and increase vasoconstriction, which reduces the blood supply to the optic nerve and leads to vision loss.
Second, smoking is not only harmful to the body, but also has a great influence on the psychology.
1, affecting the state of daily life. Under the influence of nicotine, smokers will gradually become dependent on tobacco. Once they don't smoke, they will have anxiety, anxiety and other emotions, and even affect their sleep, which will lead to poor daily life.
2, affect the learning state. Teenagers' learning is a process of establishing a good network connection between two nerves. Learning is to remember things in the process of constantly solidifying this connection. Teenagers' smoking will affect the solidification process of memory and make their memory decline, which will lead to the decline of learning ability.
