Home remedies for a blocked nose due to a cold

A cold can inflame the lining of the nose and increase mucus, making airflow feel restricted. Congestion may be accompanied by sneezing, a sore throat or cough. Allergic rhinitis can cause similar blockage with itching and repeated sneezing, while sinusitis may bring facial pressure or thicker discharge. A blocked nose that continues outside colds can also need a different explanation.

Rest and drink enough to keep mucus less sticky. Saline spray can moisten the nasal lining; if you use a rinse, follow the product instructions and use sterile, distilled or previously boiled and cooled water. A warm shower or a humidifier may feel soothing, but avoid burns from bowls of hot water. Sleep with your head slightly raised. Ask a pharmacist before using decongestant sprays or tablets, particularly if you are pregnant or have high blood pressure; some sprays can worsen congestion when used too long.

Seek urgent help if congestion comes with severe breathing difficulty, swelling around the eyes, confusion or a severe headache. Arrange a clinical review if symptoms are worsening, facial pain is marked, fever persists, or the blocked nose does not settle after the cold. A clinician can distinguish a cold from sinusitis, allergy or another problem.

Ask whether your symptoms fit a common cold, whether a nasal medicine is suitable with your other conditions, and how long to continue saline care before arranging a review.
