What are the harms of smoking among teenagers? It will affect these four aspects

The physiological systems and organs of adolescents have not yet fully developed. If they have the habit of smoking during this period, it will have a great impact on their cardiovascular, respiratory and intellectual development, which is not conducive to their healthy growth. In addition, the harmful substances in cigarettes will enter the lungs during the smoking process. As the smoking age increases, the chance of developing lung cancer will increase.

Most teenagers smoke out of curiosity, and over time they will become dependent on cigarettes. Teenagers are in the stage of growth and development, and smoking is very harmful to the body. If they smoke during adolescence, the harm will be even greater. However, many teenagers do not know much about the harm of smoking, so they will blindly follow the trend and smoke. So, what are the harms of smoking among teenagers?
1. Impact on cardiovascular and cerebrovascular diseases <br/>Smoking directly affects cardiovascular and cerebrovascular diseases, and is also an important cause of diseases such as hypertension and coronary heart disease. Most patients with hypertension and coronary heart disease have a history of smoking. During smoking, harmful substances such as nicotine and carbon monoxide in smoke can damage vascular endothelial cells, which not only causes elevated cholesterol, but also may cause peripheral blood vessels and coronary arteries to contract, resulting in myocardial hypoxia, which is not conducive to the healthy growth of adolescents.
2. Impact on the respiratory tract <br/>If teenagers have the habit of smoking, it will affect their respiratory tract, and they will suffer from diseases such as emphysema, chronic bronchitis, and airway obstruction. According to surveys, smokers are 2 to 4 times more likely to suffer from respiratory diseases than non-smokers. Therefore, many young patients often experience symptoms such as coughing, sputum, and difficulty breathing after smoking, and may even have mild lung function impairment.
3. Impact on intelligence <br/>Smoking produces a lot of smoke, and the content of nitric oxide in the smoke is very high. After teenagers inhale these substances into their bodies, they combine with hemoglobin in the blood to form carboxyhemoglobin, which will cause the patient to lose the oxygen-carrying function. Because the human brain has a great demand for oxygen, once hypoxia occurs, they will feel distracted and have headaches. Over time, the brain will be damaged, and it will also affect intelligence and reduce students' learning ability.
4. Leading to lung cancer <br/>Teenagers are in the stage of growth and development. Their physiological systems and organs are not fully mature. They are also less resistant to harmful factors in the external environment and are prone to absorbing toxic substances, which damages their normal growth. If you have the habit of smoking during your teenage years, it will have a great impact on your lungs over time, eventually leading to lung disease and even lung cancer. In addition, the earlier you start smoking, the higher the chance and mortality of lung cancer.
