How to relieve a stuffy nose quickly

A stuffy nose may ease with saline rinsing, fluids, humidified air, and treatment matched to its cause. Resting with your head raised can make breathing more comfortable, especially at night. Relief may be temporary if congestion is caused by an allergy, a cold, or sinus inflammation.

Nasal blockage happens when the lining inside the nose becomes swollen or produces extra mucus. A common cold can cause short-lived congestion, while allergic rhinitis may bring repeated blockage, sneezing, or an itchy nose. Sinusitis can add facial pressure, reduced smell, or thick nasal discharge. Ongoing blockage may also disturb sleep; noisy breathing or pauses during sleep deserve assessment for obstructive sleep apnoea.

Use a sterile saline spray or rinse as directed, and clean any reusable device carefully. Drink enough fluid to avoid dehydration, avoid cigarette smoke and strong scents, and use a clean humidifier if dry air irritates your nose. If allergy triggers are suspected, reduce exposure to dust and consider discussing allergy medication with a pharmacist or clinician. Do not use medicated decongestant sprays longer than their label advises, because overuse can worsen congestion.

Arrange medical advice if blockage persists, keeps returning, affects sleep, or comes with facial pain, fever, reduced smell, or breathing difficulty. Seek urgent help for severe trouble breathing, swelling around the eyes, confusion, or a severe headache that is unusual for you. A clinician can examine the nose and choose treatment based on the underlying cause.

Could allergies, sinusitis, or another condition explain my blockage? Which nasal treatment is suitable for me? How long should I use a spray or rinse? Do my night-time symptoms suggest a sleep-related breathing problem?
