? 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.
