Generally there is no time limit for saline nasal washings and patients can adhere to it for a long time. Patients wash their nose with saline mainly to remove excessive secretions in the nasal cavity. For normal people, if there are cases of sticky and hard nasal secretions, washing the nose with saline will achieve good results and can prevent mucosal damage. Patients with rhinitis may experience nasal congestion due to a significant increase in secretions, so saline nasal wash can be used appropriately to promote the patency of the nasal passage in the short term and to improve the symptoms of nasal congestion. Therefore, there is no time limit for saline nasal wash, and patients can adhere to it for a long time. However, most of them can only relieve the symptoms. If you want to improve the symptoms completely, you also need to correspond to the treatment according to the specific type of rhinitis to avoid delay and prevent more serious complications. In addition, patients should supplement their bodies with various vitamins, especially B vitamins, which can improve the resistance of the nasal mucosa. It is also necessary to eat more fresh vegetables and fruits, which also help the absorption of vitamins. At the same time, proper exercise can improve the body’s resistance and prevent the nasal mucosa from developing lesions.
