Patients with sinusitis may have their symptoms aggravated by blowing on the air conditioner because some patients’ nasal mucosa is particularly sensitive after blowing on the air conditioner, and they keep sneezing and running their nose, which may easily aggravate the obstruction of the patient’s sinus opening, which is not conducive to the discharge of sinus secretions outward. The accumulation of fluid in the patient’s sinus may increase, the mucous membrane of the sinus cavity will be congested and edematous, and the patient will have a feeling of dizziness and swelling. In terms of treatment, it is recommended to actively apply nasal irrigation to improve the patient’s nasal congestion, reduce the secretion of nasal mucus, and take oral eucalyptus pinene enteric soft capsule to promote the outward secretion of sinus fluid. After active treatment, the patient’s sinusitis should improve to a certain extent. In life, patients with sinusitis must pay attention to avoid direct blowing of air conditioners to avoid aggravating the patient’s condition.
