Why is every epidemic lung injury? How should we protect our lungs?

According to the observation in recent years, almost all the epidemics are mostly caused by lung problems, such as SARS, avian influenza, influenza A H 1N 1 and H7N9 avian influenza that occurred last year, and the new pneumonia that broke out this time. If you look closely, you will find that they are all respiratory diseases, and the lungs are the first to be injured.

In this regard, some netizens questioned why every epidemic is lung injury.

Because the lung has a fatal weakness compared with other organs!

The epidemic situation is mainly caused by infection, and the infection routes are mainly divided into three categories: including digestive system transmission; Respiratory tract transmission; Blood diffusion.

The lung belongs to the respiratory system, which is directly connected with the outside world, and can also be said to be in direct contact with nature. So the difference between lung and other organs lies in its extroversion.

Because the lung organs are highly open, bacteria and viruses can directly enter Fei Baozhong's body through breathing, and then attack the lungs and cause pneumonia.

Therefore, in many epidemics, the respiratory tract and lungs are the first to be harmed.

In addition, respiratory infectious diseases themselves are difficult to prevent and control.

First of all, compared with digestive system transmission and blood-borne transmission, as long as personal health care is done well, infection can be obviously suppressed, while respiratory infectious diseases can be transmitted through the air, making prevention more difficult.

Secondly, today's society is highly mobile and developed, and diseases transmitted through the respiratory system are more likely to cause large-scale epidemic spread, which is difficult to prevent and control.

In addition, serious air pollution is constantly challenging our respiratory defense system, which further provides opportunities for virus attacks.

Why are they also attacked by viruses? Some people get sick, others don't?

This is because there is a certain gap in human defense ability. In fact, our respiratory system has a complete defense system. If the virus wants to attack humans, it needs to pass through layers of immune defense checkpoints from the nasal cavity, throat, trachea and alveoli to form lesions. People with a sound and powerful respiratory defense system can kill viruses through their own immune defense mechanism, thus protecting themselves from viruses and other pathogenic microorganisms. So some people will not get sick even if they are attacked by viruses.

How to better protect our lungs?

First of all, we must understand that our lungs are most afraid of catching cold. Many respiratory diseases begin with catching a cold, so be sure to keep warm and avoid catching a cold.

Secondly, I want everyone to understand that the severity of lung diseases is closely related to our immunity, so we should pay attention to establishing a healthy lifestyle, not staying up late, not smoking, balanced nutrition, proper exercise and so on. In order to better improve our immunity and reduce virus invasion.
