You’ve just turned off the lights. The house is quiet. Instead of drifting off, you lie awake, mouth open, fighting a clogged nose. Breathing through the mouth tastes dry and metallic. Your pillow feels too high. Every small noise seems louder. A blocked nose may seem minor, but it wrecks sleep fast. This guide gives practical, evidence‑based steps you can do tonight and habits to stop congestion coming back.

Why congestion often feels worse at night

• Gravity and posture: Lying flat redistributes blood flow to the head, increasing nasal swelling.
• Nasal cycle: Your nose naturally alternates congestion between sides every few hours; lying down can exaggerate the blocked side.
• Lowered airway tone during sleep: Muscles relax and airflow reduces, so mild congestion becomes obstructing.
• Home factors: Dry air, dust mites in bedding and late‑day allergen exposure all add up after sunset.

Fast relief you can try now (10–20 minutes)

• Saline spray or rinse: A simple isotonic saline spray will thin mucus and clear allergens. For a deeper cleanse, use a neti pot or squeeze bottle with sterile or boiled, cooled water.
  • How to: lean over a sink, tilt head, let solution flow through one nostril and out the other. Breathe through the mouth.
  • Warning: use distilled, boiled or sterile water to avoid infection.
• Steam inhalation: Hot steam moistens mucous membranes and loosens mucus.
  • How to: boil water, pour into a bowl, drape a towel over your head and inhale for 5–10 minutes. Add a few drops of eucalyptus or menthol oil if tolerated.
  • Caution: keep safe distance to avoid burns.
• Warm compress: Place a warm flannel across the nose and cheeks for 5–10 minutes to ease sinus pressure.
• Menthol or camphor rubs: A mentholated chest rub or inhaler under your nose gives a sensation of easier airflow, though it doesn’t reduce swelling.
• Adjust sleeping position: Elevate the head of the bed or use an extra pillow to reduce nasal blood pooling. Sleeping on the less congested side can help.
• Hydration and a hot drink: Warm non‑caffeinated fluids (herbal tea, broth) can thin secretions and soothe the throat.

Pre‑bed habits to reduce nightly congestion (1–2 hours before sleep)

• Shower before bed: A warm shower provides steam and clears allergens from skin and hair.
• Use a humidifier: Keep bedroom humidity around 40–50%. Too dry air thickens mucus, too humid encourages dust mites and mould.
• Avoid late‑night triggers: Don’t smoke or drink alcohol close to bedtime; both worsen nasal swelling. Avoid heavy meals and spicy food if they cause reflux or congestion.
• Change bedding regularly: Wash pillowcases weekly in hot water and encase pillows and mattresses if you have allergies.
• Limit pet access to the bedroom: Dander is a common culprit for nocturnal congestion.

Over‑the‑counter options: when and how to use them

• Saline nasal sprays: Safe for nightly use and excellent first‑line therapy.
• Topical decongestant sprays (oxymetazoline, xylometazoline):
  • Use: effective quick relief for severe blockage.
  • Warning: limit to 3–5 consecutive days to avoid rebound congestion (rhinitis medicamentosa).
• Oral decongestants (pseudoephedrine, phenylephrine):
  • Effect: reduce nasal blood flow and swelling.
  • Cautions: can raise blood pressure, cause jitteriness or insomnia; avoid if you have hypertension, heart disease, or are sensitive to stimulants.
• Antihistamines:
  • Non‑sedating: for daytime allergy control.
  • Sedating (first‑generation): may help sleep but can dry nasal secretions and leave you groggy.
• Nasal steroids (fluticasone, budesonide):
  • Best for: chronic allergic rhinitis. They reduce inflammation but take several days to reach full effect.
  • Safety: generally safe for long‑term use under guidance.

Natural and breathing techniques that help

• Nasal breathing practice: Consciously breathe through the nose while awake to improve nasal tone. Simple nasal breathing exercises for five minutes before bed can reduce mouth breathing overnight.
• Buteyko light techniques: Short breath‑hold exercises can lower hyperventilation tendencies that worsen congestion perception.
• Gentle sinus massage: Use fingertips to apply light pressure along the brow and cheekbones to ease trapped mucus.
• Essential oils (with care): Eucalyptus or peppermint in a diffuser can provide symptomatic relief; avoid direct application inside the nostrils and do not use with infants.

When congestion is more than a nuisance

• Consider allergies if symptoms are seasonal, include sneezing, itchy eyes or always happen in a certain room.
• Think chronic rhinitis for daily, long‑standing congestion without clear allergic triggers.
• Structural problems (deviated septum, enlarged turbinates) may need ENT assessment if one side is persistently blocked or you use decongestant sprays frequently.
• See a GP urgently if you have high fever, severe facial pain, swollen eye or vision changes — these can signal sinus infection complications.

A practical 7‑step bedtime checklist

1. Take a warm shower and dry off allergens.
2. Use a saline spray or perform a gentle rinse.
3. Run a humidifier at 40–50% if air is dry.
4. Elevate your head with an extra pillow.
5. Sip a warm, non‑caffeinated drink.
6. Apply a menthol rub on chest (not under the nose) if needed.
7. Practice three minutes of calm nasal breathing lying on your less congested side.

Quick troubleshooting

• If congestion wakes you repeatedly despite these measures, note timing and triggers for your GP.
• If a decongestant spray helped but then lost effect, stop using it and seek medical advice to break the rebound cycle.
• Persistent snoring or daytime sleepiness with congestion could indicate sleep apnoea; discuss with your GP.

Final note about lasting relief

Short‑term fixes are useful, but combining nightly habits with targeted treatments gives the best outcome. For people with recurring sleep disruption, addressing bedroom allergens, using a regular saline routine and consulting about nasal steroids or allergy testing will usually restore restful nights.
