Does your child regularly complain of headaches, particularly after school, during the afternoon or when they are tired?
Perhaps they become irritable, stop playing, want to lie down or complain that their head hurts.
Headaches in children can have several contributing factors, including dehydration, missed meals, poor sleep, stress, migraines and vision difficulties.
For some children, nutritional factors such as inadequate food intake or low iron may also be worth considering.
Understanding when headaches occur and what is happening around that time can help identify possible triggers.
Health Snapshot
| What to Look For | Why It Matters |
|---|---|
| Skipped meals | Hunger and long gaps between meals may trigger headaches in some children. |
| Low fluid intake | Dehydration can contribute to headache symptoms. |
| Poor sleep | Inadequate or disrupted sleep may increase headache frequency. |
| Timing | Headaches after school, sport or missed meals may reveal useful patterns. |
| Nausea or sensitivity to light | May occur with childhood migraine. 1, 2 |
What Causes Headaches in Children?
Children can experience different types of headaches, including tension-type headaches and migraines.
Possible contributing factors include:
- Missed meals or inadequate food intake
- Dehydration
- Poor sleep
- Emotional stress
- Viral illnesses
- Vision difficulties
- Migraines
- Changes in daily routine
More than one factor may contribute to a headache.
For example, a child who has slept poorly, eaten very little lunch and spent the afternoon playing sport may have several possible triggers occurring together.
Could Hunger Be Triggering Headaches?
Some children experience headaches when they have gone a long time without eating.
This can be particularly noticeable after school.
A child may eat a small breakfast, have a few crackers at morning tea and return home with most of their lunch untouched.
By the afternoon, they may complain of headaches, tiredness, irritability or difficulty concentrating.
Regular meals and adequate food intake are commonly recommended as part of headache management in children. 1
Why Does Protein Matter?
Protein supports normal growth, tissue repair and many essential body functions.
Including protein alongside carbohydrates can help make meals more satisfying.
For example:
- Eggs on toast for breakfast
- Chicken or cheese in a sandwich
- Natural yoghurt with fruit
- Crackers with hummus
- Leftover meat and vegetables
Rather than simply increasing snacks, consider whether breakfast and lunch provide enough energy and nutritional balance.
What About Blood Sugar?
After eating carbohydrates, blood glucose rises as food is digested and absorbed.
The body then regulates glucose levels to provide energy for normal activity.
Long gaps between meals or inadequate food intake can contribute to hunger-related symptoms, including headaches in susceptible children.
However, headaches alone do not indicate a blood glucose disorder.
A food and symptom diary may help identify whether headaches repeatedly occur after missed meals or long periods without food.
Could Dehydration Be Contributing?
Dehydration is another important factor to consider.
Children may not drink enough water during busy school days, particularly when they are distracted by activities or playing sport.
Signs of inadequate fluid intake may include:
- Thirst
- Darker urine
- Less frequent urination
- Tiredness
- Headaches
Dehydration is recognised as a possible headache trigger, and maintaining regular hydration is commonly recommended for children with recurrent headaches. 1
Check whether your child has access to water throughout the day.
An almost-full water bottle returning from school may be a useful clue.
Could Low Iron Be Contributing?
Iron is essential for producing haemoglobin, which transports oxygen around the body.
It also supports normal brain development, energy production and cognitive function.
Iron deficiency and iron deficiency anaemia can be associated with tiredness, reduced concentration and headaches. 3
Children with restricted diets, particularly those eating very little meat or other iron-rich foods, may have inadequate iron intake.
How Much Iron Does My Child Need?
Australian recommended daily iron intakes are:
- 1–3 years: 9 mg
- 4–8 years: 10 mg
- 9–13 years: 8 mg
Examples of Iron-Rich Foods
Approximate iron content per cooked portion:
- Beef, 50 g: 1.2–1.5 mg iron
- Lamb, 50 g: 0.8–1.2 mg iron
- Chicken, 50 g: 0.4–0.7 mg iron
- Chicken liver, 20 g: 2–3 mg iron
- Cooked lentils, 100 g: approximately 3 mg iron
- Cooked spinach, 75 g: approximately 2–3 mg iron
Values vary depending on the food and preparation.
Iron from meat is generally more readily absorbed than iron from plant foods.
A nutritional review may be helpful when headaches occur alongside tiredness, poor concentration or a very limited diet.
What About Magnesium?
Magnesium is an essential mineral involved in normal nerve and muscle function.
Dietary sources include:
- Nuts
- Seeds
- Legumes
- Wholegrains
- Green leafy vegetables
Magnesium has been investigated in migraine prevention, although evidence for supplementation in children remains limited. 4
Reviewing dietary magnesium intake may be useful when a child’s diet is highly restricted.
However, headaches alone do not establish magnesium deficiency.
Could Poor Sleep Be Involved?
Sleep plays an important role in brain function, emotional regulation and overall wellbeing.
Children who experience insufficient or disrupted sleep may be more susceptible to headaches.
Look for:
- Difficulty falling asleep
- Frequent waking
- Snoring
- Mouth breathing
- Restless sleep
- Difficulty waking in the morning
- Daytime tiredness
Sleep disturbances and headaches can occur together, particularly in children with migraines. 1, 2
If headaches are frequent, reviewing sleep patterns alongside diet and hydration can provide useful information.
Could My Child Be Experiencing Migraines?
Yes. Children can experience migraines, although symptoms may differ from those commonly described by adults.
Possible signs include:
- Moderate to severe headache
- Nausea or vomiting
- Sensitivity to light
- Sensitivity to sound
- Wanting to lie down in a quiet, dark room
- Reduced interest in playing or eating
Younger children may struggle to explain what they are experiencing.
Instead, parents may notice that their child becomes unusually quiet, irritable or withdrawn.
Migraine is a recognised cause of recurrent headaches in children and adolescents. 2
What Do We Commonly See in Clinic?
At The Children’s Naturopath, we see children whose parents are concerned about recurring headaches, particularly during the afternoon or after school.
Sometimes a review of the child’s routine reveals that they have eaten very little lunch, consumed limited water or experienced poor sleep.
In other children, headaches may occur alongside tiredness, restricted food preferences or concerns about iron intake.
We look at nutritional intake, meal timing, hydration, sleep and symptom patterns to help identify possible contributing factors.
The aim is to understand whether practical changes to the child’s daily routine may help reduce avoidable headache triggers.
Try This: A Two-Week Headache Diary
For two weeks, record:
- Time the headache begins
- How long it lasts
- Severity of the headache
- Breakfast and lunch intake
- Snacks and meal timing
- Water intake
- Sleep duration and quality
- Physical activity
- Stressful events
- Nausea or vomiting
- Sensitivity to light or sound
Notice whether headaches occur more frequently on school days, after sport, following missed meals or after poor sleep.
Simple First Steps
1. Review breakfast and lunch
Make sure your child has opportunities to eat satisfying meals that include protein.
2. Encourage regular hydration
Check whether your child is drinking enough water during school and physical activity.
3. Look at sleep quality
Notice whether headaches occur after restless or insufficient sleep.
4. Consider nutritional intake
Review iron-rich foods and overall dietary variety, particularly when tiredness or poor concentration is also present.
5. Keep a headache diary
Recording symptoms can help identify repeated patterns and possible triggers.
Frequently Asked Questions
Can skipping breakfast cause headaches?
Yes. Missed meals and long gaps without food may trigger headaches in some children.
Can children have migraines?
Yes. Childhood migraines may involve headache, nausea, vomiting and sensitivity to light or sound. 2
Can low iron contribute to headaches?
Iron deficiency anaemia may be associated with headaches and tiredness. However, symptoms alone cannot confirm iron deficiency. 3
Can dehydration cause headaches?
Yes. Inadequate fluid intake can contribute to headaches, particularly during hot weather or physical activity.
When does a headache need urgent assessment?
A sudden severe headache, confusion, weakness, fever with neck stiffness or headache following significant head injury requires urgent assessment.
When to Seek Further Assessment
Headaches that become more frequent, worsen over time, regularly interrupt sleep or affect daily activities warrant further assessment.
Sudden severe headache, neurological symptoms, repeated vomiting or fever with neck stiffness require urgent attention.
