Headaches are not only an adult problem. Children can experience them too, from an occasional mild headache after a long school day to recurrent migraines that interfere with school, activities, and family life.
Most headaches in children are not caused by something serious. Tiredness, dehydration, illness, stress, skipped meals, eye strain, and migraine are among the many possible causes.
However, parents should pay attention when headaches are severe, recurring, suddenly different from usual, or accompanied by other worrying symptoms.
Understanding the pattern of your child’s headaches can help you decide when simple home care may be enough and when professional assessment is important.
What Causes Headaches in Children?
Children can develop headaches for many reasons.
Common causes may include:
▪ Dehydration
▪ Lack of sleep
▪ Skipping meals
▪ Viral illnesses
▪ Stress or anxiety
▪ Eye strain
▪ Too much time in hot environments
▪ Migraine
▪ Tension-type headaches
Sometimes there is no obvious trigger.
A single mild headache that improves after water, food, rest, or sleep is often less concerning than repeated headaches that progressively worsen or interfere significantly with everyday life.
Tension-Type Headaches
Tension-type headaches are common.
Children may describe pressure or tightness around the forehead or head rather than intense throbbing.
These headaches may be associated with tiredness, stress, long periods of concentration, or muscle tension.
They may occur after a busy school day or during periods of emotional pressure.
Rest, hydration, regular meals, relaxation, and addressing possible triggers may help.
If headaches become frequent or significantly affect daily activities, speak with a healthcare professional.
Migraine in Children
Children can experience migraine, sometimes from a relatively young age.
Migraine may cause moderate to severe headache, often with throbbing or pulsing pain.
Children may also experience:
▪ Nausea or vomiting
▪ Sensitivity to light
▪ Sensitivity to sound
▪ Dizziness
▪ Abdominal discomfort
▪ Desire to lie somewhere quiet and dark
Migraine in children can sometimes be shorter than migraine in adults.
Some children develop warning symptoms, known as aura, before the headache begins.
These can include visual disturbances, tingling, or other neurological symptoms.
A child with suspected migraine should be assessed by an appropriate healthcare professional, particularly when symptoms are recurring.
Dehydration and Headaches
Not drinking enough can contribute to headaches.
Children may become dehydrated during hot weather, physical activity, illness, or simply because they forget to drink during school.
If your child develops a mild headache, consider when they last had water.
Encourage regular hydration throughout the day rather than waiting until thirst becomes intense.
Watch for other signs of dehydration such as dark urine, reduced urination, dry mouth, or unusual tiredness.
Skipping Meals Can Trigger Headaches
Long periods without eating may contribute to headaches in some children, particularly those prone to migraine.
Breakfast can be especially important on school days.
Older children and teenagers may skip meals because they are rushing, not hungry in the morning, dieting, or simply too busy.
Encourage regular balanced meals and snacks appropriate to your child’s needs.
If headaches repeatedly occur at similar times of day, consider whether meal timing may be contributing.
Sleep and Headaches
Poor sleep can trigger or worsen headaches.
Children who regularly go to bed late, wake repeatedly, or do not get enough sleep may be more prone to headaches.
Teenagers are particularly vulnerable because homework, social media, gaming, activities, and early school mornings can reduce sleep.
Look at the entire sleep routine.
If headaches often follow late nights or irregular sleep, improving sleep habits may help.
Persistent sleep problems deserve medical attention in their own right.
Stress and Emotional Factors
Children can experience headaches during periods of stress.
School pressure, exams, friendships, bullying, family changes, or anxiety can sometimes contribute.
This does not mean the pain is “imaginary.”
Stress can produce genuine physical symptoms.
Ask your child how things are going without immediately assuming the headache has an emotional cause.
If you notice headaches consistently appearing before school, tests, particular activities, or stressful events, it may be useful to explore what else is happening.
Screen Time and Eye Strain
Long periods using computers, tablets, phones, or gaming devices may contribute to eye strain and headaches in some children.
Children may also experience headaches if they need vision correction but have not yet been assessed.
Encourage regular breaks during prolonged screen use and make sure lighting and viewing distance are comfortable.
If your child repeatedly complains of headaches after reading, schoolwork, or screen use, consider arranging an eye examination.
Headaches During Illness
Headaches commonly accompany viral infections.
A child with a cold, flu-like illness, or fever may complain of headache along with tiredness, body aches, or reduced appetite.
These headaches often improve as the illness resolves.
However, severe headache associated with fever, neck stiffness, unusual drowsiness, confusion, or a concerning rash needs urgent medical attention.
Parents should assess the entire child rather than treating headache as an isolated symptom.
What Can Parents Do at Home?
For an occasional mild headache when the child otherwise appears well, simple measures may help.
Encourage your child to:
▪ Drink water
▪ Eat if they have skipped a meal
▪ Rest somewhere quiet
▪ Take a break from screens
▪ Get some sleep if tired
A cool compress on the forehead may feel soothing.
If pain medication is needed, use only an age-appropriate product and follow dosing instructions carefully.
Speak with a pharmacist or healthcare professional if you are uncertain what medication is suitable.
Keep a Headache Diary
If headaches occur repeatedly, keeping a simple record can be useful.
Write down:
▪ When the headache started
▪ How long it lasted
▪ Where the pain was located
▪ What the child ate and drank
▪ How much sleep they had
▪ Activities before the headache
▪ Other symptoms
▪ Any medication given
Patterns may emerge.
For example, headaches may repeatedly occur after poor sleep, long periods without food, or particular stressful situations.
A headache diary can also provide useful information for your child’s doctor.
Frequent Pain Medication Can Be a Problem
Parents may understandably reach for pain relief every time a child develops a headache.
However, frequent use of headache medication can sometimes contribute to recurring headaches.
If your child needs pain medicine regularly, do not simply continue increasing how often it is given.
Discuss the headaches with a healthcare professional.
The underlying cause and pattern need assessment.
When Should a Child See a Doctor?
Arrange medical advice if headaches:
▪ Happen frequently
▪ Are becoming more severe
▪ Regularly interrupt school or activities
▪ Wake your child from sleep
▪ Are associated with repeated vomiting
▪ Follow a new or unusual pattern
▪ Require frequent pain medication
Children with recurring migraine-like symptoms should also be assessed so an appropriate management plan can be developed.
Headache After a Head Injury
A headache after a minor bump does not always mean something serious, but head injuries require careful monitoring.
Seek medical advice if the headache is severe, persistent, worsening, or accompanied by vomiting, confusion, unusual sleepiness, balance problems, memory changes, seizure, or loss of consciousness.
More significant head injuries require urgent medical evaluation.
Do not allow a child to immediately return to sport after a suspected concussion without appropriate assessment and guidance.
Emergency Warning Signs
Seek urgent medical attention if a child develops:
▪ A sudden, extremely severe headache
▪ Headache with significant neck stiffness and fever
▪ Confusion or altered consciousness
▪ Difficulty speaking or walking
▪ Weakness or numbness
▪ A seizure
▪ Repeated vomiting with severe headache
▪ A headache following a significant head injury
▪ Severe headache with a concerning rash or serious illness
These symptoms can indicate a more serious condition and should not be managed only with home pain relief.
Headaches in Younger Children
Young children may not have the language to clearly describe a headache.
Instead, they may become irritable, cry, hold their head, avoid light, stop playing, or want to lie down.
They may also vomit or appear unusually tired.
Parents know their child’s normal behaviour.
If a younger child appears significantly unwell, is behaving very differently, or repeatedly shows signs that could represent headache, seek medical advice.
When Headaches Affect School
Repeated headaches can affect concentration, attendance, homework, and activities.
If your child is regularly missing school because of headaches, professional assessment is important.
Schools may also need to know about a diagnosed migraine condition or other recurring headache disorder.
A management plan can help children access water, food, medication where prescribed, rest, or other appropriate support during the school day.
