What should you know about hay fever blocked nose?

Pollen can trigger inflammation in the lining of the nose. The lining becomes swollen and produces more mucus, narrowing the air passages. This may make breathing through the nose harder, especially at night, and can lead to mouth breathing or a dry throat. A blocked nose is not specific to hay fever: a common cold, dust-mite allergy or sinus problems can cause similar symptoms. Fever, marked facial pain, thick persistent discharge or symptoms confined to one side deserve a clinical assessment.

Limit pollen exposure by keeping bedroom windows closed during high-pollen periods, changing after outdoor activity and washing bedding regularly. Saline spray or irrigation can loosen mucus and wash away irritants; use it exactly as directed. A pharmacist can discuss allergy medication, including antihistamines or an anti-inflammatory nasal spray. Spray technique matters: aim away from the middle wall of the nose and breathe gently. Do not use decongestant sprays for longer than the label advises, because overuse can maintain congestion.

Seek review when blockage lasts, repeatedly returns, affects sleep, or does not improve with appropriate self-care. Get urgent help for breathing difficulty, swelling of the face or mouth, severe headache with illness, or rapidly worsening symptoms. A clinician can check the nose and ears and distinguish allergic rhinitis from sinusitis or another cause.

Ask whether the pattern fits allergic rhinitis, which treatment is appropriate for you, how long to try it, and whether persistent night-time blockage needs assessment for sleep-related breathing problems.
