Nighttime stuffy nose: what should you know?

Lying down can make mucus harder to drain, while bedroom dust, mites, mould, or animal dander may irritate the nose. Allergic rhinitis often causes sneezing, itching, and clear discharge. A cold may bring sore throat or cough; sinusitis may cause facial pressure, thick discharge, or reduced smell. Loud snoring, pauses in breathing, or waking gasping needs assessment because nasal blockage can occur alongside obstructive sleep apnoea.

Use a saline spray or rinse made with sterile, distilled, or previously boiled and cooled water. Keep the bedroom free of smoke and reduce known allergens; wash bedding regularly if dust is a trigger. Drink enough fluid and try sleeping with the upper body gently raised. A pharmacist can advise on allergy medication, but avoid prolonged use of decongestant nasal sprays unless instructed because rebound congestion can develop.

Seek urgent care for severe breathing difficulty, swelling of the lips or throat, confusion, or a rapidly worsening allergic reaction. Arrange medical review for one-sided blockage with bleeding, severe facial pain or swelling, high fever, repeated sinus symptoms, or symptoms that persist and disturb sleep. Ask for assessment if you snore loudly or wake choking.

Ask whether allergies, sinus inflammation, a cold, or a structural nasal problem fits your pattern. Ask which rinse, spray, or allergy medication is suitable and how long to use it.
