Patients with rhinitis should not blow directly on the air conditioner because the mucous membrane of the nasal cavity or the inferior turbinates may induce symptoms of rhinitis if they are directly stimulated by hot or cold air, such as nasal congestion, runny nose or even incessant sneezing. The filters of air conditioners may contain a lot of dust, which may stimulate the inflammation of the nasal mucosa. Patients are advised to avoid direct blowing of air conditioners and to actively control the symptoms of rhinitis. The commonly used clinical drugs are Xiangju capsule, nasal abyss and orifice granules, patients can also spray hormonal drugs such as tretinoin nasal passages inside the nose, exercise more, and can take vitamin C tablets to improve immunity. When the patient’s immunity is significantly improved, the chances of rhinitis onset will be significantly reduced. Patients are advised not to smoke or drink alcohol.
