What Is the Cause of Headaches? Why They May Keep Coming Back

If you are getting headaches and you’re not sure why or what to do about them, this article is designed to help you think through the common possibilities in a practical way.

Headaches are not all the same.

Some need medical attention. Some may be linked to dehydration, eye strain, dips in blood sugar, stress, muscular tension, posture, or your environment. Some are migraine-related. Some may respond well to small lifestyle changes, osteopathic assessment, or treatment.

The most important thing is not to guess.

It is important to notice your headache pattern, understand what kind of help may be appropriate, and know when to seek medical advice.

What is the cause of headaches?

There is not one single cause of headaches.

A headache can come from different body systems, and the pattern often gives useful clues.

You might notice your headache:

• starts when you wake up

• builds through the afternoon or evening

• comes after screen use

• feels like a tight band around your head

• seems to start from your neck, jaw, shoulders, or upper back

• comes with migraine-type symptoms

• appears when you are tired, hungry, stressed, or under pressure

The first question is not simply, “What is causing my headache?”

A better question may be:

“What is the pattern of this headache, and what does that suggest I should do next?”

Some headaches should be checked by a doctor first. Others may be more likely to respond to practical changes, osteopathic care, or support for tension through the neck, jaw, shoulders, and upper back.

When should a headache be checked by a doctor?

Some headaches need medical attention before you try to manage them yourself or seek hands-on treatment.

Please seek medical advice promptly if your headache is:

• sudden and severe

• linked with fever, a stiff neck, or possibly a rash

• related to a recent head injury or whiplash

• associated with sudden vision changes

• associated with weakness or numbness

• linked with vertigo, nausea, or vomiting

• waking you from sleep at night

• associated with behaviour changes

• causing significant disruption to your normal daily activities

• new, unusual, worsening, or worrying

This does not mean every headache is serious. Many are not.

But it is important to take the right route first. If your headache requires medical assessment, it should occur before osteopathic treatment or self-management.

Once anything more serious has been considered or ruled out, it may be appropriate to look at more common headache patterns.

Why am I waking with headaches?

If you wake up with headaches, one possible factor is dehydration.

A dehydration headache can feel deep, heavy, and hard to shift. If you go to bed very dehydrated, you may wake with an awful headache. Heavy drinking alcohol can also leave you with a horrible dehydration headache the next morning.

A simple experiment is to sip more water throughout the day for at least five days and notice whether your morning headaches change.

If you already drink plenty of water, mineral balance may also be worth considering, especially if you have been sweating a lot, vomiting, had diarrhoea, doing a lot of sport, or waking with cramps in your legs or arms.

You can speak to a pharmacist to find out whether you may be at risk of mineral imbalance, and whether rehydration salts or electrolytes are appropriate for you.

Morning headaches may also be linked to jaw or neck tension, nighttime clenching, or the position you sleep in.

But there is an important distinction.

Waking with a headache in the morning is not the same as being woken up by a headache during the night. If your headache wakes you from sleep, especially if this is new or unusual for you, please seek medical advice.

Why do I get headaches in the afternoon or evening?

Afternoon or evening headaches may be linked to eye strain, screen use, artificial lighting, prolonged concentration, skipped meals, dehydration, or neck, shoulder, and upper back muscle fatigue.

If your headache sits behind your eyes or around your forehead, and feels worse after screen work, your eyes may be part of the picture.

Often, eye-strain headaches feel better in the morning, then build as the day goes on.

It may help to make sure your eye tests and spectacle prescriptions are up to date. If they are, the next step may be to look at your workspace, including lighting, ventilation, screen position, and how often you take breaks.

Your neck and shoulders may also be involved.

When you sit or stand in one position for long periods, the muscles around the base of your skull, neck, shoulders, and upper back can become tired and tense.

You might describe this as:

• pressure around the head

• tightness at the base of the skull

• a tight band feeling

• tension that starts in the upper back, neck, or shoulders and travels upwards

A small movement break may help. Try slowly lifting your shoulders towards your ears, gently squeezing, then releasing slowly. This is not a big stretch. It is more like giving tired muscles a small circulation boost.

In practice, we may also give specific eye muscle exercises when appropriate for the person and their headache pattern.

What can cause headaches in children, tweens, and teenagers?

If your child, tween, or teenager is getting headaches, it is understandable to feel concerned.

If their headache is persistent, severe, changing, waking them at night, or affecting their usual life, it is sensible to seek medical advice.

Once medical concerns have been addressed, one everyday factor to consider is blood sugar.

This does not mean your child has diabetes. It simply means checking whether their body is being fuelled steadily enough throughout the day.

Teenagers, especially during growth and hormonal change, can be in a very resource-hungry stage of life. If they skip breakfast, go for long gaps without eating, or rely on quick-release foods, their energy may spike and then dip.

For some children and teenagers, that under-resourced feeling may show up as a headache. Foods that burn through quickly, such as refined sugar or very carb-heavy snacks, may also leave them under-fuelled soon afterwards.

A practical one-week experiment could focus on a more stabilising breakfast.

That might include:

• eggs with something light on the side

• full-fat yoghurt with nuts, seeds, and fruit

• another protein-rich option your child is willing to eat

One of my favourite practical options is lentil brownies. They can be easy for a teenager to grab on the way to school or eat at morning break if they are not hungry first thing.

The aim is not to make food perfect.

The aim is to give the body a steadier start and notice whether the headache pattern changes.

Can stress cause headaches?

Stress can contribute to headaches, but this needs to be understood with care.

A stress-related headache does not mean the pain is imagined. It does not mean you are weak. It does not mean you are failing to cope.

In fact, headaches linked with stress often show up in people who seem to cope very well.

You may keep going. You may manage everything and everyone else. You may carry a lot without making much fuss.

But your body still has to process the load.

Stress can show up physically as:

• jaw clenching

• neck tension

• shoulder tightness

• shallow breathing

• poor sleep

• headaches

• migraine patterns

• digestive symptoms

The aim is not to remove every stress from your life. That is rarely realistic.

The aim is to help your body feel less overloaded.

That may involve rest, pacing, movement, strengthening, soothing movements, changes to your environment, and support for the physical tension patterns that build up when life has been asking a lot from you.

Any advice for migraine headaches?

Migraines are different from simple tension headaches.

A migraine may be accompanied by a persistent or intense headache, visual disturbances or an aura, and sensitivity to sound, smell, or light. You may need to lie down in a dark room, avoid noise, sleep, or step away from stimulation. Migraines may also be associated with nausea or feeling completely wiped out.

It is important to be clear: osteopathy is not a cure for migraine.

However, if you experience migraines, you may also carry a lot of tension in your neck, shoulders, jaw, upper back, and throughout your body. Easing that tension may help reduce the physical strain around the migraine pattern and help you feel better supported between attacks.

If your migraines are frequent, severe, changing, or significantly affecting your life, please speak with your GP or another appropriately qualified health professional.

Can osteopathy help tension and migraine headaches?

Osteopathy may help when headaches appear to be linked with tension in your neck, shoulders, upper back, jaw, or posture.

This may be relevant if you notice:

• a tight band feeling around your head

• pain that seems to start in your neck

• headaches after desk work or screen use

• jaw tension or clenching

• shoulder tightness that builds through the day

• headaches that ease briefly with massage but keep returning

In these cases, an osteopathic assessment can help identify whether your muscles, joints, posture, breathing pattern, jaw, or daily habits may be contributing.

Treatment may include gentle hands-on work, movement advice, simple exercises, and practical strategies to help reduce the likelihood of headaches returning.

With migraine, the aim is not to “treat the migraine” as a single isolated problem. The aim is to support you as a person experiencing migraine, especially when neck, shoulder, jaw, posture, or muscular tension may be contributing.

Can osteopathy help stress-related headaches?

If stress shows up physically in your body, osteopathy may have a role.

You may not experience stress as a thought. You may experience it as a clenched jaw, tight shoulders, a stiff neck, shallow breathing, or a recurring headache.

Osteopathic treatment may help reduce some of that physical load.

This may be especially relevant if you have tried the usual things, such as rest, painkillers, walking, stretching, or massage, but the headache keeps coming back.

The key is assessment.

If your headache pattern suggests a need beyond osteopathic care, you should be referred to your GP or another appropriate professional. If it looks more like tension, posture, jaw stress, or a musculoskeletal pattern, osteopathic care may be a helpful next step.

When should you book an appointment?

If your headache is severe, new, changing, unusual, or worrying, please seek medical advice first.

If serious causes have been ruled out, or your headaches seem linked with neck tension, jaw tension, posture, desk work, stress, screen use, or recurring muscular tightness, an osteopathic assessment may help you understand what is contributing.

At Health in Motion Osteopaths, we can assess whether your headache pattern may be linked with tension, posture, jaw, neck, upper back, or wider musculoskeletal strain. We can also advise you on whether your symptoms require medical review before treatment.
