Why do children get headaches? Understanding possible causes of headaches in children

When your child says their head hurts, it can be difficult not to worry. Some children may describe a dull ache, while others may say their head feels tight, heavy, or painful in one area. Younger children may not have the words to explain the pain clearly. Instead, they may become quieter, more irritable, less playful, or want to rest.

Headaches in children can happen for many reasons. They may be linked to fever, viral infections, tiredness, dehydration, missed meals, blocked nose, eye strain, poor sleep, or stress. Some children may also experience repeated headaches that affect school, play, rest, or daily routines.

At Joyful Seeds Paediatric & Development Clinic in Bukit Timah, Singapore, Dr Charmaine Teo and Dr Martha Liu support families with general paediatric concerns, including headaches in children, fever, tiredness, and changes in daily wellbeing. A paediatric consultation can help parents better understand possible contributing factors and whether further assessment may be appropriate.

Why Headaches In Children May Happen

Headaches in children are not all the same. Some may happen during a common illness, especially when a child has fever, cough, sore throat, blocked nose, or sinus discomfort. These headaches may improve as the child recovers.

Other headaches in children may be linked to daily habits and routines. A child who has not slept enough, skipped a meal, taken too little fluid, or spent long periods reading or using screens may be more likely to complain of head pain.

Possible contributing factors may include:

• Fever or viral illness

• Blocked nose or sinus discomfort

• Dehydration or missed meals

• Poor sleep or tiredness

• Eye strain from reading or screens

• Stress, school demands, or changes in routine

• Migraine type headaches

• Recent fall or head injury

These examples do not diagnose the cause of your child’s headache. They simply show why it is helpful to look at the full pattern.

When Headaches May Need Closer Attention

An occasional mild headache that improves with rest, fluids, food, or recovery from a short illness may not always need urgent concern. However, headaches in children should be observed more closely when they are frequent, worsening, unusual, or affecting daily activities.

Parents may wish to note:

• How often the headaches happen

• How long each headache lasts

• Where the pain is felt

• Whether there is fever, vomiting, dizziness, or vision change

• Whether there is sensitivity to light or sound

• Whether the headache affects sleep, school, play, appetite, or behaviour

• Whether the headache happened after a fall or head injury

These details can help a doctor understand whether the headache may be linked to illness, routine, migraine type symptoms, vision concerns, stress, or another factor.

Signs That Need Prompt Medical Advice

Some symptoms should be assessed promptly rather than waiting for a routine appointment.

Parents should seek urgent medical advice if headaches in children are associated with:

• A sudden severe headache

• Headache after a significant head injury

• Neck stiffness• Unusual drowsiness

• Weakness, confusion, or changes in behaviour

• Persistent vomiting

• Rash with fever

• Vision changes or difficulty walking

These signs do not confirm a specific condition on their own, but they should be assessed appropriately by a healthcare professional.

How Headaches Can Affect A Child’s Day

Headaches in children can affect more than physical comfort. A child with repeated headaches may become less interested in school activities, sports, reading, screen time, or play. Some children may feel frustrated because they cannot explain the pain clearly.

Younger children may not say that they have a headache. They may hold their head, cry more easily, avoid bright rooms, refuse food, or ask to sleep. School aged children may describe difficulty concentrating, tiredness, or sensitivity to noise.

Looking at both the headache and how it affects your child’s day can help parents understand whether the concern is occasional or becoming more disruptive.

What Parents Can Observe At Home

If your child has headaches, a simple record may be useful. Parents can note when the headache happens, how long it lasts, what the child was doing beforehand, and whether there were related symptoms.

It may help to observe whether headaches in children happen:

• During an illness

• On school days

• After screen time

• After missed meals

• After poor sleep

• During stressful periods

• After physical activity

• With vomiting, blocked nose, fever, or light sensitivity

Parents should avoid giving repeated pain relief without medical advice, especially if headaches are frequent. Any medication use should follow age appropriate guidance from a healthcare professional or the product instructions, where relevant.

When To Consider A Paediatric Review

You may consider seeking medical advice if headaches in children are frequent, severe, worsening, or affecting sleep, school, appetite, behaviour, or daily activities.

A paediatric review may also be helpful if headaches are associated with vomiting, visual changes, dizziness, weakness, confusion, persistent fever, recent head injury, or unusual tiredness.

During a consultation, the doctor may ask about your child’s headache pattern, sleep, diet, hydration, screen use, stress, medical history, family history, and related symptoms. They may also check your child’s general health and consider whether vision concerns, infections, migraine type headaches, or other factors may be relevant.

Supporting Your Child With Calm Observation

Headaches in children can feel unsettling for parents, especially when the cause is not immediately clear. Many headaches may be linked to common childhood illnesses, daily routines, or temporary triggers. However, repeated, severe, or unusual headaches should be assessed appropriately.

At Joyful Seeds Paediatric & Development Clinic in Bukit Timah, Singapore, Dr Charmaine Teo and Dr Martha Liu provide child centred care for families with headaches and general paediatric concerns. If your child has headaches that are frequent, unusual, or affecting daily life, a paediatric consultation may help clarify possible contributing factors and whether further assessment may be appropriate.
