Cough is one of the body’s defenses, and from the point of view of performance is divided into dry cough and wet cough. Dry cough refers to cough without phlegm, it is often irritating cough, such as laryngitis, suddenly smell a particularly strong odor, after crying or inhaling a foreign body, are a kind of stimulation of the upper respiratory tract, will trigger a cough. A wet cough is a cough with phlegm, a cough that expels secretions. The mucosa of the respiratory tract there are many villi, when the mucosa is stimulated by secretions, the villi will accelerate the swing, in order to push the secretions out of the body, in the process of swinging out of the body, it will lead to accelerated respiration, the airflow quickly out of the body, there is a cough. A child’s cough means, first of all, that his defenses are normal. That’s why coughing is in the vast majority of cases a good thing, not a bad thing. Whatever the cause of the cough, it will end up with secretions, which means that it will definitely end up in a wet cough. Those children who didn’t cough but got pneumonia, the body’s defense ability is rather poor, because there are already a lot of secretions in the lungs, but he didn’t cough it out, so don’t think that the child’s cough is a bad thing. Why isn’t the child’s cough better when he doesn’t have a fever? Coughing means mucosal damage that needs to be repairedIf a child coughs frequently, it means that the respiratory mucosa has problems and is in a hypersensitive state. We normally cough when we are irritated. But if the mucous membrane has been damaged, or it is not repaired after the damage, it will become very fragile, the slightest stimulus will have a reaction, especially prone to coughing. There are three steps to coughing, the stimulus to the respiratory mucosa, the process of coughing and the repair after coughing. Some parents say, the child does not have a fever, why the cough is not good? In fact, it is the respiratory mucosa is repairing. It is the infection of viruses and bacteria, which attach to the surface of the respiratory tract and irritate the mucous membrane, and at this time, the mucous membrane will secrete a secretion that can fight against viruses and bacteria. So, the fever is the process by which the body mobilizes the immune system. When the fever stops, it means that the virus and bacteria have been subdued by the immune system, and the replication of the virus and bacteria in the body no longer continues, and the body’s immune system has taken over. At this point, the nose, throat, trachea, bronchial tubes and other parts of the mucous membrane began to discharge germs outward, this process is also a kind of stimulation, so the child does not have a fever, but instead began to cough, the secretion also increased. Deep cough and shallow cough The cough is not the same part, the nature is also different. A shallow cough is short and sharp, usually in the throat, while a deep cough is in the trachea, bronchial tubes or lungs, and sounds like it’s coming from the chest. One feature that makes it easier to distinguish between a shallow cough and a deep cough is whether the sound of a cough is long or short; a shallow cough is very frequent and sounds short, while a deep cough is relatively long. Do not use the amount of secretion to determine whether your child has a shallow or deep cough. Because the entire respiratory system, from the nose and throat to the trachea and lungs, is full of secretory glands, there will be secretions in both shallow and deep coughs. Moreover, often a shallow cough makes us think that the child is more serious, with lots of phlegm, a cough that brings out some phlegm and lots of snot, when in fact the opposite is true. In fact, the opposite is true. A child with a lot of phlegm and snotty nose has a shallow cough because it is easier to cough up secretions from the upper respiratory tract and the condition is not serious. A deep cough is a shallow cough because it is easier to cough up secretions from the upper respiratory tract and the condition is not serious. At this point, you will feel the child coughing very hard, or coughing after not feel relaxed, this time the condition is more serious. Coughing at night when you don’t cough during the day? Coughing during the day and coughing at night is a shallow cough. If your child has a light cough, he or she tends to cough very little during the day, mainly with a runny nose, but coughs more at night. This is because when the child is lying down, the throat is in a low position, the nasal secretions can not be discharged through the process of the runny nose, it will flow back into the throat, irritating the throat, causing a cough, so that the child is often waking up at night coughing, so that parents feel that the child’s condition is aggravated, which is not the case. Deep cough, on the other hand, is the same regardless of day and night, and some children even cough more heavily during the day and relatively less at night, so children with deep cough can sleep well instead. Can I take anti-inflammatory drugs? A red, swollen throat is not always a bacterial infection. Careful parents may notice that their child’s throat is red and swollen when he or she coughs and worry that the child has an inflammation, so they want to use antibiotics to reduce the inflammation. A red, swollen, inflamed throat doesn’t mean it’s a bacterial infection. Inflammation is a big concept, and bacterial infections are only a small part of it, and inflammation and bacterial infections are not equivalent. What does inflammation mean? Inflammation is characterized by redness, swelling, heat and pain, inflammation of the local redness, swelling, pain, and even localized heat, like boils on the body, no matter whether the boils are big or small, the localization will be swollen, and touch will be a little pain, a little heat, belonging to the bacterial infection; if the localization is subjected to trauma, there will be a localized redness, swelling, heat and pain of the inflammatory reaction, but it is not a bacterial infection. Virus stimulation of the respiratory tract leads to coughing, throat redness and swelling, after crying or talking too much, the throat may also appear red and swollen, these causes of throat redness and swelling are not bacterial infections. Don’t fall into the misconception that a red throat means inflammation, and that inflammation means antibiotics. The purpose of our cough treatment is not to stop coughing but to dissolve phlegm, because the secretions are very sticky and there are a lot of protein components in them. If these secretions are not discharged in the respiratory tract, the bacteria go in and attach themselves to the phlegm, which then becomes a very good medium for the bacteria to multiply rapidly, leading to a double infection, i.e., a secondary infection, so the main purpose of treatment is to dissolve the phlegm, so that secretions can become thinner, so that it can be discharged more easily and not give bacteria a chance to multiply.
