Rhinitis tends to develop in the spring and autumn, as well as during the spring-summer and autumn-winter seasons, and is related to the classification of rhinitis.1 Rhinitis is divided into allergic rhinitis and non-allergic rhinitis according to its etiology. The former has significant seasonal characteristics. Patients will have episodes of disease, such as paroxysmal sneezing, nasal itching, large amounts of watery snot and nasal congestion, during the spring, autumn and spring-summer intervals, especially during the period of pollen dispersal, and most allergens are artemisia, pollen or spring poplar and willow wadding. Most allergens are dust, mites, cat hair, dog hair or food allergens; 2. Rhinitis can be divided into acute rhinitis and chronic rhinitis according to the speed of onset. Acute rhinitis can develop in all seasons, seasonal changes are susceptible, more common in winter; most chronic rhinitis, such as vasomotor rhinitis, pregnancy rhinitis, atrophic rhinitis, drug rhinitis, etc. can develop in all seasons, no specificity, but dry rhinitis will mostly occur in the autumn and winter interval, because the temperature drops, the temperature difference is relatively large, and the air is dry, the humidity in the air is relatively low, easy to induce.
