Why does my nose get stuffy when I lie down?

Lying flat changes how mucus drains and can increase the sense of nasal resistance. The normal nasal cycle, in which one side is temporarily more congested than the other, may become more noticeable at bedtime. Allergic rhinitis can cause swollen tissue, sneezing, itching, and watery discharge. A cold may cause a changing blocked nose and sore throat, while sinusitis may bring facial pressure, thick discharge, or reduced smell. If blockage is persistent on one side, a clinician should check for a structural cause rather than assuming an infection.

Try resting with your head and upper body gently raised. Drink fluids normally and consider a saline spray to moisturise and clear the nose. For a nasal rinse, use sterile, distilled, or boiled then cooled water and clean the device as directed. Keep the bedroom free of smoke and strong fragrances, and note whether symptoms follow dust, pets, or a particular sleeping position. Ask a pharmacist about Allergy Medication if allergy symptoms are present. Follow package directions for any decongestant spray; prolonged use can cause rebound congestion.

Book an appointment if the problem lasts beyond a short illness, repeatedly interrupts sleep, or does not improve with simple measures. Seek urgent help for difficulty breathing, swelling around an eye, severe headache or facial pain, confusion, a stiff neck, or a high fever. Snoring with gasping or breathing pauses also merits assessment.

Does the position-related pattern suggest allergy, sinus inflammation, or a nasal structural problem? Which spray or rinse is suitable for me? Should my sleep symptoms be assessed?
