Patients with rhinitis can turn on the air conditioner, but the air conditioner should try to clean it regularly because a lot of dust will accumulate on the air conditioner filter, and if it is not cleaned regularly, as the air conditioner runs, the dust mites in the room will increase significantly, and the patient’s nasal congestion or allergies will increase significantly. Also, avoid blowing the air conditioner directly on yourself and pay attention to adjusting the direction of the air conditioner. Patients with rhinitis can spray fluticasone propionate nasal spray when the symptoms of nasal congestion appear. If the patient has more nasal mucus, you can use nasal spray with azelastine hydrochloride. If the patient has obvious nasal itching, he can take oral montelukast sodium tablets, and also rinse the nasal cavity with physiological sea saline, exercise more, strengthen personal resistance, and wear a mask when going out to avoid contact with allergens.
