The symptoms and manifestations of runny nose when the nose sees cold wind are often caused by allergic diseases in the mucous membrane of the nasal cavity. The cooler cold air stimulation factors may cause patients to have reactive nasal allergy symptoms such as nasal congestion, nasal itching, sneezing and clear nasal discharge. When the surrounding temperature and environment become normal, the symptoms of runny nose, itchy nose and sneezing may gradually improve or recover on their own. Therefore, for patients who have similar symptoms repeatedly, they should pay attention to strengthen the protection of nasal mucosa and take protective measures such as wearing a mask if necessary. If symptoms such as runny nose and sneezing still persist and recur, hormonal nasal spray medications, such as mometasone furoate nasal spray, can be used accordingly to help improve symptoms and minimize the duration of the disease. If necessary, further oral anti-allergy medications such as loratadine are needed.
