Is It Hay Fever or a Constant Cold? A Parent’s Guide to Allergic Rhinitis in Children
Some children seem to have a cold that never fully goes away. They wake up sneezing, rub their nose, sniff constantly, breathe through their mouth, cough at night, or have a blocked nose for weeks.
Parents often ask: “Is this just another cold, or could it be hay fever or allergy?”
This is an important question. Viral colds are common in children, especially at nursery and school. But if symptoms keep returning, last for weeks, follow a seasonal pattern, or include itchy eyes and sneezing, allergic rhinitis may be part of the problem.
Allergic rhinitis is inflammation and irritation inside the nose caused by something the child is allergic to, such as pollen, house dust mites, mould or animal skin flakes. NHS lists symptoms including sneezing, blocked or runny nose, itchy nose and reduced sense of smell.
Mr Gaurav Kumar, Consultant ENT Surgeon, assesses children with nose, ear, throat and paediatric ENT concerns from London, East London, Brentwood, Romford, Ilford, Redbridge, Chelmsford and wider Essex.
This guide explains how parents can recognise possible allergic rhinitis, how it differs from repeated colds, and when further assessment may help.
What Is Allergic Rhinitis?
Allergic rhinitis means the lining of the nose reacts to an allergen. If the trigger is pollen, many people call it hay fever. NHS describes hay fever as an allergic reaction to pollen that commonly affects the nose, eyes, mouth and throat.
Triggers can include:
- grass, tree or weed pollen
- house dust mites
- mould
- animal dander
- indoor dust
- seasonal outdoor exposure
- bedroom allergens
In children, allergy symptoms may be obvious, but they are sometimes mistaken for recurrent colds.
Signs It May Be Hay Fever or Allergy
Allergic rhinitis may be more likely if your child has:
- sneezing in repeated bouts
- clear runny nose
- blocked nose lasting weeks
- itchy nose
- itchy, watery or red eyes
- nose rubbing
- mouth breathing
- poor sleep from congestion
- symptoms worse outdoors, near grass, animals or dust
- symptoms at the same time each year
- family history of allergy, eczema or asthma
NHS notes that people are more likely to get an allergy if family members have allergies, eczema or asthma.
A child with allergy may also do the classic “allergic salute”, repeatedly rubbing the nose upwards with the hand.
How Is This Different from a Cold?
A cold is usually caused by a virus. It often starts with a sore throat, runny nose, cough, tiredness or mild fever and then gradually improves.
Allergy is more likely when:
- symptoms last for several weeks
- sneezing and itch are prominent
- nasal discharge is clear rather than thick
- symptoms are triggered by pollen, dust or animals
- the child is otherwise well
- symptoms recur in a predictable pattern
However, children can have both. A child with allergic rhinitis may still catch viral colds, and allergies can make the nose feel blocked for longer.
Can Allergic Rhinitis Affect Sleep?
Yes. A blocked nose can disturb sleep. Some children breathe through their mouth, snore lightly, wake frequently or seem tired in the morning.
Allergy-related congestion can also make children more irritable, less focused at school and more tired during the day.
If your child snores heavily, pauses in breathing, gasps, sweats at night or has significant daytime tiredness, they should be assessed because enlarged tonsils, adenoids or other sleep-breathing problems may also be involved.
Can Allergy Affect the Ears?
It can contribute indirectly. The nose and the Eustachian tubes are connected, and nasal inflammation may make some children more aware of blocked ears, popping, pressure or hearing fluctuation.
However, not every child with allergic rhinitis has an ear problem. If your child has hearing loss, recurrent ear infections, glue-ear concerns, speech delay or school listening problems, a hearing test may be useful.
What Can Parents Try First?
The right approach depends on the child’s age, symptoms and triggers.
General steps may include:
- checking pollen forecasts during hay fever season
- keeping windows closed when pollen is high
- showering or changing clothes after high-pollen outdoor activity
- washing bedding regularly
- reducing dust exposure in the bedroom
- avoiding known animal triggers where possible
- using sunglasses outdoors if itchy eyes are a problem
- speaking to a pharmacist or GP about age-appropriate allergy medicines
NHS says treatments for allergic rhinitis may include antihistamines and steroid nasal sprays, depending on symptoms and suitability.
Do not use adult medication for a child without checking the correct age and dose.
Are Nasal Sprays Safe for Children?
Some nasal sprays can be very helpful, but they need to be chosen and used correctly.
Steroid nasal sprays may be recommended for allergic rhinitis in some children. NHS medicine guidance says fluticasone nasal spray is used to prevent and treat allergic rhinitis and hay fever symptoms, including sneezing, itchy and runny nose, itchy and watery eyes and blocked nose.
However, parents should check suitability for their child’s age and medical history. Technique also matters. A child may not benefit if the spray is aimed incorrectly or used only occasionally, even when regular use is advised.
Decongestant nasal sprays are different. NHS allergic rhinitis guidance states that decongestant nasal sprays or drops should not be used by children under 6 and should not be used for longer than 5 days, as prolonged use can worsen a blocked nose.
When Should Parents Seek Medical Advice?
Arrange GP, pharmacy or ENT advice if your child has:
- blocked nose lasting several weeks
- symptoms affecting sleep or school
- persistent mouth breathing
- recurrent nosebleeds with nasal sprays
- suspected allergy not improving with appropriate treatment
- ear symptoms or hearing concerns
- recurrent sinus-type symptoms
- asthma symptoms worsening with hay fever
- uncertainty about safe medication use
If symptoms are persistent, it may help to keep a diary of triggers, season, pets, bedroom environment, outdoor activity, sleep and medication response.
Red Flags: When Is It Urgent?
Seek urgent medical help if your child has:
- breathing difficulty
- swelling of lips, mouth, tongue or throat
- collapse or extreme drowsiness
- wheezing or severe asthma symptoms
- blue lips or severe distress
- a very unwell appearance
These could suggest a serious allergic reaction or another urgent condition. NHS allergy guidance highlights sudden swelling of the lips, mouth, throat or tongue as a serious allergic symptom.
Also seek medical advice if your child has:
- persistent one-sided blocked nose
- foul-smelling one-sided nasal discharge
- recurrent significant nosebleeds
- facial swelling
- severe headache
- high fever
- symptoms after nasal injury
These are not typical simple hay fever symptoms.
When Should a Child See an ENT Specialist?
Paediatric ENT assessment may be helpful when:
- nasal blockage is persistent
- mouth breathing is significant
- snoring or sleep disturbance is present
- symptoms do not respond as expected
- there are recurrent ear or hearing concerns
- the diagnosis is unclear
- there are recurrent nosebleeds
- adenoids, tonsils or structural nasal issues may be contributing
The aim is not to medicalise every child with hay fever. The aim is to identify children whose symptoms are persistent, complicated, unclear or affecting quality of life.
Paediatric ENT Care in London and Essex
For families in London and Essex, hay fever and allergic rhinitis can affect daily life, school, sleep, sport and travel. Children may struggle more during pollen season, in dusty bedrooms, around pets, or during changes in weather and environment.
Mr Gaurav Kumar provides paediatric ENT assessments for children with persistent blocked nose, mouth breathing, snoring, recurrent ear symptoms, hearing concerns, and nasal allergy symptoms across London, East London, Brentwood, Romford, Ilford, Redbridge, Chelmsford, and Essex.
A careful assessment can help distinguish allergic rhinitis from repeated colds, adenoid problems, sinus symptoms, structural nasal blockage and other ENT causes.
Conclusion
A child with weeks of sneezing, blocked nose and runny nose may not simply have “another cold”.
Allergic rhinitis and hay fever are common and can affect sleep, comfort, school and family life. Many children improve with practical trigger reduction and age-appropriate treatment advice, but persistent or complicated symptoms deserve proper assessment.
Seek urgent help for breathing difficulty, swelling of the lips or throat, severe wheeze, collapse or a very unwell child.
If symptoms are persistent, recurrent or affecting sleep, hearing or daily life, paediatric ENT review may help clarify what is driving the problem and what support is appropriate.
