Can patients with allergic rhinitis use air conditioning?

Allergic rhinitis patients are generally advised to avoid air conditioning, as exposure to air-conditioned environments may exacerbate their symptoms.

Allergic rhinitis is commonly triggered by exposure to allergens such as cold air, dust mites, pollen, and other environmental factors. If air conditioning itself acts as a trigger—either due to the cold air it produces or the accumulation of allergens (e.g., mold, dust mites) within the system—patients should avoid using air conditioners altogether. Continued use may worsen symptoms, impede recovery, and potentially lead to complications such as bronchial asthma, upper airway cough syndrome, or secretory otitis media. Even in cases where air conditioning is not the primary cause of allergic rhinitis, the cold, dry air it generates can irritate the nasal mucosa and aggravate symptoms—including sneezing, rhinorrhea, lacrimation—as well as induce olfactory dysfunction, ocular symptoms, and pulmonary manifestations. Therefore, regardless of the underlying cause, individuals with allergic rhinitis are generally advised against using air conditioning.

Management of allergic rhinitis begins with strict avoidance of known allergens. When air conditioning is unavoidable, maintaining indoor cleanliness and ensuring the temperature is set at a moderate, non-chilling level are essential precautions.
