A stuffy nose during pregnancy can happen even when you are not sick. Pregnancy hormones can make the lining inside your nose swell, which can cause blocked nose, runny nose, sneezing, postnasal drip, and mouth breathing.

This is often called pregnancy rhinitis. Cleveland Clinic describes pregnancy rhinitis as nasal congestion that starts during pregnancy and is not caused by infection or allergies. (Cleveland Clinic)


1. Use Saline Spray

Saline spray is one of the safest first steps.

Try it when:

  • Your nose feels dry.
  • Your nose feels blocked.
  • You have thick mucus.
  • You wake up congested.
  • You feel postnasal drip.

Saline helps moisturize the nose, thin mucus, and soothe irritated nasal tissue. Mayo Clinic says saline nose spray can help moisturize the nose and thin mucus. (Mayo Clinic)


2. Try a Saline Rinse

A saline rinse can clear mucus better than spray.

Use:

  • Sterile saline rinse bottle
  • Neti pot
  • Pre-made saline packets
  • Distilled water
  • Previously boiled and cooled water

Do not use plain tap water unless it has been boiled and cooled first.

Mayo Clinic suggests nasal irrigation with saline solution as needed and says to use specially prepared water. (Mayo Clinic)


3. Use Steam Carefully

Steam may help loosen mucus.

Try:

  • Warm shower
  • Sitting in the bathroom while hot water runs
  • Bowl of warm water nearby
  • Warm compress over the nose and cheeks

Avoid burning-hot steam. Do not put your face too close to boiling water.


4. Sleep Slightly Elevated

Congestion often feels worse at night.

Try:

  • Extra pillow
  • Pregnancy pillow
  • Wedge pillow
  • Raising the head of the bed slightly
  • Side sleeping with head support

This can reduce mucus pooling and make breathing easier.


5. Use a Humidifier

Dry air can make the nose feel blocked, sore, or crusty.

Try:

  • Cool-mist humidifier
  • Bowl of water near radiator
  • Keeping bedroom air less dry
  • Cleaning the humidifier regularly

A humidifier may help if you wake up with a dry mouth, sore throat, or blocked nose.


6. Drink More Often

Thick mucus is harder to clear.

Try:

  • Water
  • Warm lemon water
  • Soup
  • Broth
  • Herbal tea approved in pregnancy
  • Electrolyte drink if you are also vomiting

Small frequent sips can help if nausea makes drinking harder.


7. Reduce Nose Irritants

Pregnancy can make your nose more sensitive.

Avoid or reduce:

  • Perfume
  • Smoke
  • Vaping
  • Dust
  • Strong cleaning sprays
  • Scented candles
  • Air fresheners
  • Strong laundry scent
  • Pet dander if it triggers you
  • Cold dry air

NHS advises avoiding triggers when possible for non-allergic rhinitis. (nhs.uk)


8. Try Gentle Movement

A short walk can sometimes open the nose temporarily.

Try:

  • Walking indoors
  • Walking outside if air quality is good
  • Light housework
  • Gentle stretching
  • Changing position often

Do not push yourself if you are dizzy, faint, short of breath, or unwell.


9. Ask Before Using Decongestants

Do not start decongestant tablets or sprays without checking with your doctor, midwife, or pharmacist.

Some nasal sprays may be used in pregnancy, but decongestant sprays can cause rebound congestion if used too long. Cleveland Clinic warns that oxymetazoline sprays can cause rebound congestion and become hard to stop. (Cleveland Clinic)

If your provider says a decongestant spray is okay, use it only for the short time they recommend.


10. Ask About Allergy Treatment If Needed

If your stuffy nose comes with itchy eyes, sneezing, or clear watery mucus, allergies may be part of it.

ACOG says some antihistamines, including cetirizine and loratadine, may be safe during pregnancy, and that there is a corticosteroid nasal spray that is safe to use during pregnancy. Ask your provider what is right for you. (ACOG)


11. Watch for Sinus Infection Signs

A stuffy nose can turn into or feel like a sinus infection.

Call your provider if you have:

  • Face pain
  • Tooth pain
  • Thick green or yellow mucus
  • Fever
  • Worsening headache
  • Severe pressure around the eyes or forehead

When It Is Usually Less Worrying

A stuffy nose is usually less worrying when it is:

  • Mild
  • Comes and goes
  • Clear mucus
  • No fever
  • No chest pain
  • No severe headache
  • Better with saline, steam, or humidifier
  • Not stopping you from sleeping or eating
