The dangers of smoking among teenagers

Many teenagers nowadays mature early, and some of them start to smoke like adults for the sake of so-called face. They only know that smoking can make them look like bosses, but they ignore the fact that smoking is harmful to health. By the time parents discover their young children are smoking, it is too late to stop them. Therefore, anti-smoking education for teenagers should start in advance, and we should not wait until something happens before trying to make up for it.

The harm of smoking to teenagers:

Smoking is very harmful to the health of growing adolescents, and has a certain degree of impact on bone development, nervous system, respiratory system and reproductive system. Because the systems and organs of adolescents are not fully developed, their functions are not yet sound, and their resistance is weak, the harm of smoking is greater than that of adults. In addition, because the respiratory tract of adolescents is narrower than that of adults and the cilia of the respiratory mucosa are not fully developed, smoking can damage the respiratory tract and cause inflammation, increase breathing resistance, reduce lung capacity, affect the development of the adolescent chest, and thus affect their overall development.

The large amount of nicotine contained in tobacco is also toxic to the brain nerves. It can cause students to suffer from memory loss, lack of energy, and poor academic performance. The survey found that students who smoke have lower academic performance than those who do not smoke. In addition, adolescents are in a critical period of sexual development. Smoking can reduce testosterone secretion by 20%-30%, reduce sperm count and cause sperm deformity, and delay menarche in girls and cause menstrual disorders. Smoking among teenagers will also reduce the age of onset of coronary heart disease, hypertension and cancer. Relevant data show that the younger the age of smoking, the more serious the harm to health. The mortality rate of those who start smoking at the age of 15 is 55% higher than that of those who start smoking after the age of 25, and more than 1 times that of non-smokers.

Smoking damages the brain and affects intelligence. Tobacco smoke contains high levels of carbon monoxide. After carbon monoxide is inhaled into the human body, it combines with hemoglobin in the blood to form carboxyhemoglobin, which prevents hemoglobin from combining with oxygen normally to form oxyhemoglobin, and thus loses its oxygen-carrying function. Because the human brain has a large demand for oxygen and is very sensitive to hypoxia, smoking too much will make you feel unfocused, and even cause headaches and dizziness. Over time, the brain will be damaged and thinking will become slow. This will inevitably affect study and work, and cause students' academic performance to decline.

Amblyopia in adolescents caused by smoking is called "tobacco toxic amblyopia". The main symptom is visual impairment: blurred vision, which is difficult to correct with glasses and gradually worsens with decreased vision.

Having seen so many effects of smoking on our health, do you still dare to try it? If you don't smoke, you act like an adult, which is behavior only bad kids have. The demeanor of an adult comes from the heart. Don’t do anything that would harm your body just for the sake of momentary pleasure. Parents’ advice is also for our healthy growth. We should not be disgusted by them just because of it. They are all for our own good.
