It should be noted that: 1, salt water concentration, temperature and operation method should be well mastered. Persistence is the most important thing. There are many rhinitis patients who say that washing their nose with salt water has no effect, which is actually the reason why they don't insist on it every day.
3, wash the nasal vestibule alone, and then wash the deep nasal cavity. Rushing directly from one nostril to another nostril or directly to the deep part of the nasal cavity, it is easy to flush the dirty things in the nasal vestibule directly to the deep part of the nasal cavity, and the deep structure of the nasal cavity is very complicated, which is why some people can't blow out their nose. You might as well try.
