? Cough and yellow phlegm are rhinitis, and runny nose is also one of the symptoms of rhinitis. You should observe whether there is a runny nose or booger, whether there is a runny nose from blowing cold air or eating spicy food, or whether there is anything sticky sticking to your throat from the back of your nose. In one case? You already have rhinitis. The purulent secretion of rhinitis is transported to the throat through nasal cilia, which stimulates the throat mucosa and causes cough. And the secretions spit out by coughing become phlegm. If there is no abnormal vibration or sound in the chest when breathing with the mouth open, phlegm has nothing to do with the lower respiratory tract. ) in this case, directly treat rhinitis, and the cough will naturally disappear? In the future, pay attention to prevent colds and avoid new rhinitis caused by colds, so there will be no such situation. Because rhinitis is caused by long-term or repeated colds, the hormone level increases during pregnancy and the air quality in the living environment is poor, which leads to a large number of deaths of nasal cilia and reduces the detoxification ability of nasal cavity. Harmful substances stay in the nasal cavity, causing damage to nasal mucosa. ? The inflammatory part of rhinitis will secrete a lot of purulent substances, that is, nasal mucus. The nose contains a lot of bacteria and inflammatory substances. Because it is too thick, the nasal cilia can't be transported out in time. The accumulation of nasal mucus in the nasal cavity leads to the aggravation of nasal inflammation, which is easy to cause sinusitis. At the same time, it is more likely to cause a cold, forming a vicious circle of rhinitis → cold → rhinitis aggravation → easier to catch a cold. At the same time, these nasal mucus containing a lot of inflammatory substances will be transported to the nasopharynx by nasal cilia, and will be too thick to stick to the nasopharynx and throat, and cannot slip into the stomach for sterilization.

? Inflammatory substances inside stimulate the soft tissues of the throat, causing pharyngitis, and in severe cases, it shows cough symptoms. If these secretions are spit out from the mouth, it becomes what we call phlegm. Therefore, pharyngitis is usually accompanied by rhinitis. This is also the reason why the effect of treating pharyngitis alone is poor. To thoroughly treat rhinitis, we can directly use nasal Le Shu and nasal lavage device with physiological salt to gently soak and nurse the delicate tissues of the nasal cavity, and thoroughly remove the snot on the surface of the tissue and the virus and other harmful substances in the snot. Usually wash it once in the morning and evening, especially as soon as possible after getting up in the morning. ? To achieve the effect, we must pay attention to the method of use (be careful not to use inferior or salt, the nasal mucosa itself is easy to be damaged, and safety and hygiene are equally important). With the disappearance of nasopharyngeal irritants, pharyngitis will naturally disappear. At the same time, there is no irritant in the nasal cavity, and the inflammation of each tissue will gradually disappear. Improve the physiological environment of nasal cilia and reduce the burden. The detoxification ability of nasal cilia gradually recovered. The nasal cavity has changed from the previous vicious cycle to a benign cycle, and the diseased tissue cells are gradually replaced by new healthy cells. Rhinitis will be cured, and people will not be easily infected. If it is not used correctly or the nose washing is not good, the nasal cavity will still be damaged by various harmful irritants, which will affect the therapeutic effect. At first, if you want to take effect early, you can also increase the number of uses. ? This is physical therapy, which is very safe for the body and can be used with confidence. Restoring a healthy nasal cavity will also improve the air quality entering the lower respiratory tract, which has an important protective effect on the health of the whole respiratory system, especially in foggy days, which can improve the filtering ability of the nasal cavity to smog particles and protect the health of the respiratory system. All kinds of respiratory diseases and respiratory infectious diseases will naturally stay away from you. It can also be used in the morning and evening to prevent various respiratory diseases such as colds, flu, rhinitis and sinusitis, and prevent postoperative recurrence of rhinitis and sinusitis. Therefore, if this method is used well, it will benefit for life.
