Correct understanding of cough
Cough itself is not a disease, but a normal physiological reflex of the human body. Our breathing is divided into inhalation and exhalation. Cough is the strengthening of exhalation process.
In many cases, this intensive exhalation exercise has health significance. For example, when smog weather occurs, we can expel pathogenic particles from our lungs by coughing, so that our bodies are not harmed.
Including some respiratory diseases, such as pneumonia, chronic bronchitis, asthma, etc., can strengthen breathing, thus avoiding hypoxia caused by decreased respiratory ability.
Cough is harmful only when it is very severe and there is no sputum discharged. Severe cough can cause instantaneous high pressure in the lungs, causing physical damage to alveoli and trachea. Especially dry cough without phlegm, lung and trachea lack the protection of body fluids, which is more likely to cause injury.
Stopping coughing blindly is harmful to health.
It is precisely because of cough itself that it has a health significance that cannot be ignored. When coughing occurs, stopping immediately will interfere with the body's reflex function and affect the normal circulation law.
First of all, it is likely to cause poor sputum discharge, and harmful substances cannot be effectively excreted. Dust particles, automobile exhaust, viruses and germs all enter our lungs directly through breathing. It hinders the self-purification of the lungs. Where will these harmful substances go?
Stopping coughing blindly is equivalent to cutting off the self-purification channel of the lungs, and the accumulation of harmful substances in the lungs is much more harmful than coughing.
In addition, cough itself is also a function of the human body to regulate and strengthen breathing. It is totally unreasonable to stop coughing immediately without knowing the reason, just like stopping a baby from crying.
Cough should be traced back first.
The occurrence of cough is a signal of human body. Only by knowing the cause of cough can we stop coughing effectively.
Such as pneumonia and bronchitis. The cause of cough is bacteria or chlamydia. At this time, it is meaningless to stop coughing if the bacteria are not killed.
For the season of alternating winter and spring, the high incidence of colds and coughs is the human body's stress response to climate and environmental changes. Cough when catching a cold is a reflection of fire in the lungs. Simply relieving cough is not only helpful to the condition, but may further interfere with the self-healing law of the human body.
