Spring is the season of high incidence of allergic rhinitis, with many people experiencing symptoms such as nasal congestion, runny nose and sneezing. In the south, dust mite allergies are more common, while in the north, pollen allergies are the main problem.

To avoid allergens, regularly open windows for ventilation in sunny weather, wash and change sheets and bedding frequently, clean air conditioning filters regularly, and clean indoor carpets. Drug treatment is one of the effective ways to relieve allergic symptoms.
