The smell of bad breath hardly reaches the olfactory mucosa of your nasal cavity. In addition, there are several possibilities for the appearance of bad breath. One is oral inflammation or dental caries, the other is gastrointestinal inflammation, and the third is rhinitis. Oral problems are the most direct factor. If there is inflammation or dental caries in the mouth, there are a lot of food residues in the mouth, which will emit an odor after being decomposed by bacteria. In this way, the oral inflammation is cured, the teeth and tongue are also clean when brushing your teeth, and the problem of bad breath disappears. The second case is the least common, because there is a sphincter at the lower part of the esophagus where it connects with the stomach, which only allows food to enter the stomach downwards and prevents food or smell from entering the esophagus upwards. Except for frequent vomiting or burping, there will be no bad breath at other times.

The third situation, like the first one, is the most common. When there is rhinitis, the inflammatory secretions in the nasal cavity will reach the throat with the delivery of nasal cilia. When this secretion contains saprophytic bacteria, the secretion in the throat will give off an odor, which will be taken away by the airflow when speaking, forming a feeling of bad breath. In this case, the nose often smells. You should observe whether there is a runny nose or booger, a runny nose when blowing air conditioning, or something sticky sticking to your throat from the back of your nose. In one case, you already have rhinitis. In this case, take good care of rhinitis and the breath problem 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 a long-term or repeated cold, the hormone level during pregnancy increases, and the air quality in the living environment is poor, which leads to a large number of deaths of nasal cilia, which reduces the detoxification ability of the nasal cavity, and harmful substances stay in the nasal cavity, causing nasal mucosal damage.

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 deterioration 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, you can directly soak the delicate tissue of the nasal cavity and thoroughly remove the snot on the surface of the tissue and the virus in the snot.

? Usually wash once in the morning and once in the evening. To achieve the effect, we should pay attention to the use according to the method (be careful not to use fake and shoddy, 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. The physiological environment of nasal cilia is improved, the burden is reduced, and the detoxification ability of nasal cilia is gradually restored. The previous vicious circle in the nasal cavity has turned into a virtuous circle, and the diseased tissue cells are gradually replaced by new healthy cells, and rhinitis is cured, and people are less likely to be 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.
