Treatment for a blocked nose at night

Lying down can make nasal swelling feel more noticeable, while bedroom dust, mites or dry air may aggravate congestion. A common cold, allergic rhinitis, sinusitis or chronic sinusitis can block the nasal passages. Loud snoring, pauses in breathing and waking unrefreshed raise a different concern, such as obstructive sleep apnoea, and deserve assessment.

Use a saline spray or rinse prepared with safe water, keep the bedroom free of smoke and reduce dust exposure. Raising the head slightly may make breathing more comfortable. A pharmacist or doctor may recommend an antihistamine or nasal steroid when allergy is involved. Decongestant nasal sprays should not be used longer than directed because overuse can worsen blockage. Check products carefully if you have other conditions or take regular medicines.

Arrange review if blockage lasts beyond a typical cold, repeatedly affects sleep, is mainly on one side, or comes with facial pain, reduced smell or recurrent nosebleeds. Seek urgent help for severe breathing difficulty, swelling of the lips or face, confusion, or a high fever with marked illness.

Ask whether the pattern fits allergy or sinus disease, which spray is appropriate, how to use a rinse safely, and whether snoring or breathing pauses need a sleep assessment.
