Smoking is harmful to health, and smoking less is not good for the body. While smoking can make the smoker feel relaxed and happy. However, the inhalation of nicotine and hundreds of harmful substances in tobacco will also be inhaled into the human body, which will bring great harm.

Smoking is harmful to health, with one out of every two smokers dying from tobacco-related diseases in the future. The average life expectancy of smokers is 10 years shorter than that of non-smokers. However, due to the lag in the harm of smoking to the body, it generally takes several years to decades of incubation before the occurrence of diseases.

The nicotine in tobacco has pharmacological effects and can make people feel relaxed and happy, because when nicotine binds to nicotine acetylcholine receptors in the brain, it produces neurotransmitters such as dopamine, which will make smokers feel happy, excited, and refreshed. Hundreds of harmful substances in tobacco can also be inhaled into the human body, bringing a series of harms.

Smoking is not beneficial, smoking may damage the respiratory system, and it will also increase the incidence of cancer, so it is recommended that smokers quit smoking as soon as possible and go to the hospital for a medical examination to clarify their physical condition.

1. Damage to the respiratory system: tobacco contains a large number of harmful substances, such as nicotine, tar, carbon monoxide, etc., which can damage the respiratory system, lead to damage to the cilia of the respiratory tract, reduce the ability of the airway to clear, and can also affect the local defense function of the respiratory system and increase the incidence of respiratory tract infections. In particular, long-term smoking can lead to chronic inflammation of the small airways, narrowing of the small airways, obstructive ventilatory dysfunction, and even chronic respiratory failure and chronic cor pulmonale in severe cases.

2. Increase the incidence of cancer: the harmful substances in tobacco have the possibility of causing cancer, which can lead to an increase in the incidence of malignant tumors, especially the incidence of lung cancer is significantly higher than that of normal people, so it is recommended that people who smoke for a long time regularly review chest CT to check whether there is lung cancer and deal with it in time;

3. Other disadvantages: such as it may increase the incidence of cardiovascular and cerebrovascular diseases and other related diseases, and have a certain impact on reproductive function, especially for pregnant women, smoking may also affect the growth and development of the fetus.

Studies have shown that children from smoking families are much more deficient in vitamin C than children from non-smoking families. In addition, the more severe the passive smoking, the more likely the child is to develop tooth decay. Although the word "no smoking" is written in many public places, there are still many people who smoke.

Smoking is not only harmful to oneself, but also to passive smokers. Especially in families with children, if adults smoke regularly, passive smokers are often more susceptible to respiratory diseases and even delay the development of lung function. In addition, passive smoking can also lead to vitamin C deficiency, which can adversely affect growth.

What are the adverse effects of passive smoking on children? 1. It is easy to cause respiratory diseases. Children with one or both parents who smoke are more likely to develop chronic respiratory diseases than children whose parents do not smoke.

Long-term passive smoking, which begins at an early age, can have a very bad impact on the health of the respiratory system. 2 Pneumonia and tracheitis are more likely. Studies have shown that children who grow up in smoking households have twice the risk of tracheitis and pneumonia compared to children who grow up in non-smoking households.

Passive smoking from an early age increases the burden on your child's lungs and increases the likelihood of pneumonia and tracheitis. 3. It is easy to develop the habit of smoking. Children who have watched their parents smoke from an early age can easily accept smoking as part of their daily life.

From learning to smoke occasionally, slowly, you may well become a new smoker yourself.
