Patients who have symptoms of nasal hyperventilation when their nose is cold are often due to the fact that the patient’s nasal mucosa is more sensitive and may have chronic rhinitis or allergic rhinitis, as well as chronic sinusitis. Inflammatory and allergic disease factors in the patient’s nasal cavity are likely to make the nasal mucosa relatively sensitive, easily causing irritation of the nasal mucosa due to drastic changes in temperature, triggering congestion, swelling and edema of the nasal mucosa, resulting in nasal congestion and lack of ventilation. Some patients may also show symptoms of nasal itching, sneezing, clear water nasal discharge or mucopurulent nasal discharge. If the symptoms of non-ventilation persist, attention should be paid to further detailed examination of the nose to clarify the diagnosis and take targeted treatment and improvement measures.
