What are the hazards of air quality to human body

With the rapid expansion of the economy and the acceleration of urbanization, the air quality is getting worse and worse. In recent years, our hope of seeing the sun every day has become increasingly slim. Sometimes there is smog for half a month. And the number of people suffering from respiratory diseases is increasing. So people began to pay more attention to the problem of air pollution. So what are the hazards of air quality to the human body? Let us learn about it together.

There are three ways for the human body to be harmed, namely, inhaling polluted air, surface skin contact with polluted air and ingesting food containing atmospheric pollutants. In addition to causing respiratory and lung diseases, it can also cause harm to the cardiovascular system, liver, etc., and in severe cases can take a person's life.

Once inhaled, pollutants enter the bronchi directly and interfere with gas exchange in the lungs. Air pollution can have adverse effects on people who already suffer from chronic cardiovascular and respiratory diseases, and accelerate the occurrence of these chronic diseases in healthy people. Even though the air quality has improved in some areas, air pollution will still have significant adverse effects on public health, and this impact is likely to increase with the aging of the population, the increase in the incidence of chronic diseases, the rapid expansion of the economic scale and the acceleration of urbanization. Air pollution causes great harm to the human body.

Some chronic respiratory diseases or the causes of their aggravation are closely related to air pollution. Lower concentrations of pollutants can also irritate the respiratory tract and cause bronchial constriction, increasing respiratory resistance and weakening respiratory function.

The harm of air pollution to human body can be divided into the following three categories:

1. Acute hazards: When the concentration of pollutants is very high in a short period of time, or when several pollutants enter the human body together, they can cause acute hazards to the human body.

2. Chronic hazards: Chronic hazards mainly refer to the harm caused by the continuous effects of small doses of pollutants on the human body. Such as the impact of air pollution on the incidence of chronic respiratory inflammation.

3. Long-term harm: The harm of environmental pollution to the human body usually manifests itself after a long latent period, such as the carcinogenic effect of environmental factors. The main carcinogenic factors in the environment are physical, chemical and biological factors. Physical factors, such as leukemia and lung cancer caused by external radiation exposure or inhalation of radioactive substances, and biological factors, such as tropical malignant lymphoma, have been proven to be caused by a virus transmitted by blood-sucking insects. Chemical factors: According to animal experiments, there are more than 1,100 carcinogenic chemicals. In addition, pollutants have a great impact on genetics. All living things have the characteristic of genetic variation. The harm of environmental pollution to human genetics is mainly manifested in mutagenic and teratogenic effects.

Through the introduction of the above article, I believe everyone is aware of the harm of air quality to the human body. Poor air quality can make people easily get angry and cause gastrointestinal disorders. Therefore, we should try to eat a light diet, eat less spicy and greasy food, drink more water, pay more attention to rest, and exercise more. Thereby improving your own immunity.
