Whether or not to suction or rinse a child's nose is a question that many parents ponder.

What causes green nasal discharge and excessive runny nose in children?

Viral rhinitis and nasopharyngitis.

This is the most common cause in young children. When they have a cold or flu, children usually:

  • Clear nasal discharge, which then turns cloudy or green.
  • Nasal congestion
  • Sneezing, mild cough

A runny nose turning green doesn't necessarily mean a serious infection.

Smoke, dust, excessively cold air conditioning, or dry air can all cause increased nasal mucus production in children. (Illustrative image)

Sinusitis in children

Children over 3 years old are more susceptible to sinusitis. Common symptoms include:

  • Thick green nasal discharge
  • Nasal congestion lasting more than 10 days
  • Bad breath or headache

Allergic rhinitis

Allergies cause children to have a constant runny nose, but the nasal discharge is usually clear, accompanied by:

  • Itchy nose
  • Itchy eyes
  • Sneezing in long bursts

Environmental influences

Smoke, dust, excessively cold air conditioning, or dry air can all cause increased nasal mucus production in children.

Should nasal suction be used for children with excessive nasal discharge?

You should use a nasal aspirator when:

Nasal suction helps babies breathe easier when:

  • Nasal congestion makes it difficult for babies to feed and sleep well.
  • Thick nasal discharge, child unable to blow their nose on their own.
  • It needs to be cleaned before eating or breastfeeding.

Do not use a nasal aspirator when:

Using a vacuum cleaner too often can:

  • Causes mucosal damage
  • Nasal congestion worsens due to edema.
  • Increased risk of middle ear infection.

Safe frequency: only about 2–3 times a day when absolutely necessary.

Should you rinse your nose regularly?

You should wash when:

Suitable for children over 1 year old with thick nasal discharge. Use:

  • 0.9% physiological saline solution
  • Nasal spray for children with gentle pressure.

Do not rinse your nose when:

Do not rinse your nose if:

  • Children under 6 months old (unless directed by a doctor)
  • Children with middle ear infections
  • When babies cry and struggle, there is a risk of choking.
  • Use a strong spray directly.

Is a green runny nose a sign of bacterial infection and does it require antibiotics?

A green nose doesn't always mean an infection. In most cases, it's just:

  • The body's reaction to the virus.
  • Accumulation of immune cells in nasal discharge

Children only need antibiotics when they show signs of:

  • A thick, green nasal discharge lasting more than 10–14 days.
  • Persistent high fever
  • Pain in the face or around the eyes
  • Unusual odor coming from the nose.

Antibiotics should only be used as directed by a doctor.
