Runny Nose in Children: Why It Gets Worse During Winter

Medically reviewed on 2024-09-26

A runny nose in children during winter is common and can be caused by viral infections, dry indoor air, or increased exposure to indoor allergens. Although occasional nasal discharge is usually harmless, persistent symptoms may indicate an underlying condition that needs medical attention.

Many parents notice that their children experience more nasal congestion, sneezing, and mucus production during colder months. Changes in temperature, indoor environments, and seasonal infections can all contribute to these symptoms.

At ENT Clinic of Excellence in Dubai Healthcare City, we help parents understand the possible causes of their children’s nasal symptoms and identify when an ENT assessment may be necessary.

What Causes a Runny Nose in Children During Winter?

Several factors can contribute to a runny nose in children during winter. Understanding the cause can help parents choose appropriate ways to manage their child’s symptoms.

1. Viral Respiratory Infections

Colds and other respiratory infections are common causes of a runny nose in children. These infections can circulate throughout the year, with certain respiratory viruses becoming more prevalent during particular seasons.

When a virus enters the nasal passages, the immune system responds by producing more mucus to help trap and clear infectious particles.

Other symptoms may include:

  • Sneezing and nasal congestion
  • Sore throat
  • Coughing
  • Mild fever
  • General tiredness

Most common colds improve within 7–10 days. However, if symptoms persist, worsen, or return after initially improving, a medical assessment may be needed.

2. Dry Indoor Air

During cooler weather, indoor heating and air conditioning can contribute to low humidity. Dry indoor air may irritate the delicate lining of a child’s nasal passages, causing dryness, irritation, and discomfort.

Children may experience:

  • Dryness inside the nose
  • Nasal irritation
  • Crusting or minor nosebleeds
  • A sensation of nasal congestion

Although dry air does not necessarily cause increased mucus production, irritation can make existing nasal symptoms more noticeable.

Maintaining comfortable indoor humidity and using saline nasal sprays can help soothe irritated nasal passages.

3. Indoor Allergens

Children often spend more time indoors during colder weather, increasing their exposure to certain household allergens.

Common indoor allergens include:

  • Dust mites: Microscopic organisms commonly found in mattresses, pillows, carpets, and upholstered furniture.
  • Pet dander: Tiny skin flakes and other allergen-containing particles shed by cats, dogs, and other animals.
  • Mold: Fungi that grow in damp areas, bathrooms, and poorly ventilated spaces.

These allergens can trigger allergic rhinitis in children, causing symptoms that may resemble a common cold.

Unlike a viral infection, allergic rhinitis is not contagious and may cause recurring or persistent symptoms.

Common signs include:

  • Frequent sneezing
  • Clear, watery nasal discharge
  • Itchy nose
  • Itchy or watery eyes
  • Nasal congestion
  • Post-nasal drip

If your child experiences these symptoms repeatedly, particularly without fever, an allergy assessment may help identify the underlying trigger.

4. Changes in Temperature

Moving between cooler outdoor environments and warmer indoor spaces can sometimes trigger nasal symptoms.

The nose naturally regulates the temperature and humidity of the air we breathe. Sudden temperature changes may stimulate nasal glands and cause temporary watery discharge, even when a child does not have an infection.

This type of nasal response is usually temporary and may improve once the child adjusts to the surrounding environment.

How to Relieve a Runny Nose in Children During Winter

Most mild cases of a runny nose can be managed with simple supportive measures at home. The appropriate approach depends on the child’s age, symptoms, and underlying cause.

Here are some practical ways to help your child feel more comfortable:

1. Use a Humidifier When Needed

A clean cool-mist humidifier may help add moisture to dry indoor air, particularly when heating systems reduce humidity.

Remember to clean the humidifier regularly according to the manufacturer’s instructions to prevent mold and bacterial growth.

2. Try Saline Nasal Sprays or Drops

Saline nasal sprays and drops help moisturize the nasal passages and loosen mucus, making it easier for children to clear their noses.

They can also help remove allergens and other irritants from the nasal lining.

Choose an age-appropriate product and follow the instructions provided. For infants and younger children, saline drops followed by gentle nasal suction may be helpful.

3. Encourage Proper Hydration

Drinking enough fluids helps maintain normal mucus consistency and prevents dehydration.

Offer your child:

  • Water throughout the day
  • Warm soups and broths
  • Other age-appropriate fluids

Adequate hydration can help keep nasal secretions easier to clear.

4. Reduce Exposure to Indoor Allergens

If allergies are contributing to your child’s symptoms, reducing exposure to common household triggers may help.

Consider the following:

  • Wash bed sheets and pillowcases regularly.
  • Keep carpets and upholstered furniture clean.
  • Use appropriate dust-mite covers for mattresses and pillows.
  • Address damp areas and visible mold.
  • Keep pets away from your child’s sleeping area if pet allergies are suspected.

If symptoms continue despite these measures, consult an ENT specialist or allergy specialist for further evaluation.

When Should You See an ENT Specialist?

A runny nose is usually temporary, but persistent or recurrent nasal symptoms should not always be attributed to winter weather or common colds.

An ENT assessment may help identify conditions that require specific treatment, including:

  • Allergic rhinitis: Inflammation of the nasal lining caused by exposure to allergens.
  • Chronic rhinitis: Persistent inflammation of the nasal passages that can cause ongoing discharge and congestion.
  • Enlarged adenoids: Enlarged tissue behind the nose that may contribute to nasal obstruction, mouth breathing, and snoring.
  • Chronic or recurrent sinusitis: Inflammation involving the sinuses that may cause prolonged nasal symptoms.
  • Nasal obstruction: Blockage of the nasal passages that may affect comfortable breathing.

Signs Parents Should Not Ignore

Consider arranging an ENT consultation if your child:

  • Has nasal discharge or congestion lasting more than 10 days without improvement.
  • Experiences frequent or recurring nasal symptoms.
  • Has persistent difficulty breathing through the nose.
  • Frequently breathes through the mouth, especially during sleep.
  • Snores regularly or experiences disturbed sleep.
  • Has persistent post-nasal drip or coughing.
  • Experiences recurrent ear infections or concerns about hearing.

Seek prompt medical attention if your child has difficulty breathing, appears unusually unwell, develops swelling or redness around the eyes, or has other severe or concerning symptoms.
