There are more people consulting about coughs and quite a lot of coughs are treated clinically, why? Because of the anatomical conditions of the respiratory system of children, especially infants, such as few nasal hairs, rich nasal blood vessels, thin mucous membranes, narrow trachea, few alveoli and little oxygen, children’s colds tend to start from the nose, then to the throat, and then to the trachea and even the lungs. In terms of Chinese medicine, children’s table gas is not enough, and the external guard is not solid, and with improper care, it is easy to repeat colds. Therefore, to prevent children from catching a cold, we must pay attention to the hygiene of the nose, do not use our hands to dig the nasal cavity of children, which can easily lead to injuries to the mucous membrane of the nasal cavity, thus causing recurrent rhinitis and increasing the chances of upper respiratory tract infections, or often take children to places with poor air such as shopping malls, clubs and other crowded places, and do not treat the cough in time, until it develops into a tracheal or lung problem before seeking a doctor. This prolongs the cough and complicates the treatment. I often see children who have problems with their throat, trachea, and throat, which makes treatment slower, and because of nursing care and repeated colds and coughs, the child’s health decreases, resulting in a chronic recurrent cough. Therefore, to know the above reasons, parents will pay attention to how to prevent the occurrence of cough.
