Headaches are common at every age, including in children, and the overwhelming majority are not a sign of anything serious. This article covers the usual causes, what migraine looks like in children, and — most importantly — the specific features that mean a headache needs prompt medical attention.
Common, usually benign causes
Most headaches in children can be traced to an ordinary trigger:
- A viral illness such as a cold or flu, often with the headache appearing alongside fever (see Fever in Children for general guidance on fever itself)
- Dehydration or a missed meal
- Poor or insufficient sleep
- Stress, particularly around school or exams
- Excessive screen time in some children
- Occasionally, an uncorrected vision problem — this is worth ruling out if headaches are frequent, but it's one possible contributor among several rather than the usual cause
These headaches are typically not severe, don't progressively worsen over weeks, and settle with rest, fluids, and simple pain relief.
Migraine in children
Migraine isn't only an adult condition — children can have it too, sometimes from quite a young age. In children, migraine often looks a little different than in adults: attacks can be shorter, pain is sometimes on both sides of the head rather than one, and nausea, vomiting, or sensitivity to light and sound are common. Some children also experience an "aura" beforehand — visual changes such as flashing lights or zig-zag lines — which is a recognized part of migraine and not itself a cause for alarm when it follows this familiar pattern. A family history of migraine is frequently present. Migraine in children is generally managed with identifying and reducing triggers, adequate sleep and hydration, and simple pain relief for individual episodes — a pediatrician can advise on this based on the specific pattern your child experiences.
What to observe and note
Before your child's appointment, it helps to note:
- When headaches happen and how often
- How long each one lasts, and how severe it seems
- Where the pain is (all over, one side, back of the head)
- Any associated symptoms — nausea, vomiting, visual changes, sensitivity to light or noise
- Possible triggers you've noticed (missed meals, poor sleep, stress, screen use)
This pattern is often more useful to a doctor than the headache itself being examined at a single visit. Daily or near-daily headaches, or a pattern that is clearly changing or worsening, are themselves worth a routine appointment even without any single alarming feature.
Warning signs that need urgent assessment
Most headaches don't need emergency care, but the following features are genuine red flags and should prompt urgent medical attention:
- A sudden, severe headache unlike any your child has had before ("worst headache of their life")
- Headache with a stiff neck and fever (possible meningitis; see fever warning signs for fever-specific red flags)
- Headache following a significant head injury, especially if it persists beyond about a week
- Headache with weakness, numbness, difficulty speaking, confusion, or a change in alertness
- A seizure occurring with the headache
- Repeated or persistent vomiting alongside the headache, rather than a single episode, especially without an obvious other explanation
- A headache pattern that is clearly worsening or changing over weeks, rather than staying the same
- New or persistent visual disturbance — as distinct from the brief, familiar visual aura some children experience just before a known migraine
Research looking specifically at children brought to emergency departments for headache found that an abnormal finding on neurological examination, and vomiting, were the strongest indicators of a serious underlying cause. The same research found that a headache waking a child at night, or pain at the back of the head, were not reliable warning signs on their own. That doesn't mean these are never worth mentioning — a headache severe enough to wake a child from sleep is still worth discussing with your pediatrician — but on their own, without other red-flag features, research specifically looking at emergency presentations suggests they don't reliably predict a dangerous cause. It's easy to feel that every headache needs to be treated as an emergency; most don't, and a calm, observant approach serves most families better than alarm.

Frequently asked questions
Does my child need a brain scan? Not routinely. Imaging is guided by the history and a neurological examination — a normal exam and a reassuring pattern of headaches generally do not require a scan. Your pediatrician will advise if imaging is genuinely needed.
Can stress really cause physical headaches in children? Yes. Stress-related (tension-type) headaches are common and are real, physical pain — often described as a tight band around the head — even though there's no structural problem causing them.
