If the dry weather causes the symptoms of dry mucous membrane in the nose, patients can use some oil-based nasal drops, such as compound menthol nasal drops, and also use physiological seawater spray, which can moisturize and protect the nasal mucous membrane, thus improving the uncomfortable feeling of dry nose. In addition, patients can also take measures to properly regulate the air by splashing some water on the ground indoors or using humidifiers to increase the humidity of the air, which can also help improve the symptoms of dry nose. Patients themselves need to pay attention to drink more water and eat a light diet. They can eat more cool vegetables and fruits to replenish water and vitamins, which is also beneficial to the improvement of dry nose symptoms.
