Headache First Aid: What to Do When a Headache Strikes

When a headache begins, the decisions you make in the first few minutes often determine how severe the episode becomes and how quickly you recover. In my practice, one of the most common things I teach patients is not just what medication to take — but when, and in what combination with simple non-pharmacological measures, and critically, when none of this is sufficient and emergency help is needed.

This guide is practical first aid — what to do when a headache starts.

First: Recognise Whether This Needs Emergency Care

Before any first aid measures, quickly assess whether this headache has features that require immediate emergency attention. If any of the following apply, stop and seek emergency help — do not attempt home management first.

Go to emergency immediately if the headache is:

• Sudden and explosive — maximum severity reached within seconds (“thunderclap headache”). This is the headache of a subarachnoid haemorrhage until proven otherwise.
• The worst headache of your life — even if gradual, if it is significantly more severe than any previous headache, it requires evaluation
• Accompanied by fever and stiff neck — possible meningitis
• Following a head injury — any headache after a blow to the head needs assessment
• With weakness, facial asymmetry, slurred speech, or vision changes — possible stroke or neurological emergency
• In someone with known cancer or compromised immune system — a new severe headache in this context always needs evaluation
• With confusion or altered consciousness — any change in mental status alongside headache is an emergency

If none of the above apply, proceed with first aid.

Step 1: Move to a Suitable Environment

Where you are when a headache starts matters, particularly for migraine:

• Find a quieter space — noise amplifies pain and slows recovery
• Reduce light exposure — dimming lights or moving away from bright screens helps
• If possible, lie down — or at least sit comfortably with supported head and neck
• Step away from strong smells — including food odours, perfumes, or chemicals, which are strong migraine triggers

In an office or public setting, even stepping into a bathroom or quieter corridor for a few minutes during the early phase of an attack can make a meaningful difference.

Step 2: Hydrate Immediately

Dehydration is both a cause and an accelerant of headache. Drink a full glass of water as soon as a headache begins — slowly, not rushed. If you have been poorly hydrated during the day (hot weather, heavy activity, alcohol the night before, or air-conditioned environments), drink two full glasses.

Do not wait to see if the headache develops before hydrating. Hydration is safe, fast, and genuinely helpful.

Step 3: Eat Something If You Have Skipped a Meal

If it has been more than four hours since you last ate, low blood sugar may be contributing to the headache. Eat something with a moderate amount of complex carbohydrate and some protein — not sugary snacks that will cause a blood sugar spike and crash. A banana, a handful of nuts, a piece of wholegrain toast. Simple and accessible.

Do not eat a large heavy meal during an active headache — this can worsen nausea and discomfort.

Step 4: Temperature Therapy

For most headaches, a cold compress applied to the forehead or the back of the neck provides real, immediate relief. A cold pack wrapped in a cloth, a bag of frozen peas, or even a cool wet towel works.

Some people prefer warmth — a warm compress on the back of the neck for tension-type headache or a warm shower. Warmth relaxes muscle tension; cold reduces inflammation and numbs pain. Try both over time to know which works better for your headache type.

Step 5: Medication — Timing Is Everything

If you have been prescribed medication for your headache type, take it at the appropriate time according to your neurologist’s guidance.

For migraine specifically: The most important principle is early treatment. Taking migraine medication in the first 30 minutes of an attack — before the pain becomes severe — is significantly more effective than taking it when you are already in severe pain. If you wait until the headache is at its worst, the medication window is often past its most effective point.

For over-the-counter medication (if no prescription medication is available): Standard analgesics are appropriate for occasional, mild-to-moderate headaches taken according to the package instructions. The most critical caution: do not take over-the-counter pain relief more than two to three times per week. Frequent use — even of paracetamol or ibuprofen — leads to medication overuse headache, where the medication itself perpetuates and worsens headache over time.

What not to do: Do not take double doses. Do not take multiple medications together without medical guidance. Do not take someone else’s prescription medication.

Step 6: Rest — Not Passive Suffering

Rest during the acute phase of a headache is not wasted time — it often shortens the episode significantly.

• Lie down in a darkened room if possible
• Gentle breathing exercises (slow inhale for 4 counts, hold for 4, exhale for 6) activate the parasympathetic nervous system and can reduce pain intensity
• Sleep, if it comes, is genuinely therapeutic — many people wake from sleep with headache significantly improved
• Gentle neck and shoulder stretches (slow, no jerking) can relieve muscle tension contributing to tension-type headache

Step 7: Avoid Making It Worse

Common mistakes that extend or intensify headaches:

• Continuing to stare at a screen — this is one of the hardest things to ask of people in a work context, but screen use during an active headache prolongs it significantly
• Staying in a noisy or bright environment when there is an option to move
• Skipping the next meal — recovering from a headache while fasting is harder
• Caffeine excess — while small amounts of caffeine can help some headache types, excess caffeine or using it to push through an attack often makes the rebound worse
• Alcohol — never appropriate during an active headache

After the Headache: Recovery Phase

Many headache conditions — particularly migraine — have a postdrome phase after the acute pain resolves: fatigue, cognitive sluggishness, neck stiffness, or a “washed out” feeling that can last hours. This is normal and is part of the condition, not a sign that something is wrong.

During this phase:

• Continue to stay hydrated
• Eat gentle, easily digestible food
• Limit demanding cognitive work if possible — this is a real phase of the headache cycle, not laziness
• Return gradually to normal activity

When First Aid Is Not Enough

If you find yourself relying on first aid measures and over-the-counter medication more than twice a week, or if attacks regularly prevent you from functioning, first aid is not the answer — treatment is. A neurological evaluation can identify the specific headache type, optimise treatment, and — where appropriate — add preventive medication that reduces how often you need first aid in the first place.

The goal is not to get better at managing attacks. The goal is to have fewer, shorter, milder attacks.

Common Questions

1. Should I take pain medication with every headache? No. Reserve medication for headaches that do not improve with non-pharmacological measures, or for diagnosed conditions where early treatment is indicated. Frequent analgesic use — more than two to three times a week — creates medication overuse headache, a pattern that is difficult to break.

2. Is coffee helpful or harmful during a headache? A small amount (one cup) can genuinely help mild headache by causing mild vasoconstriction. But it is a double-edged tool: it can also trigger rebound headache, and in habitual caffeine users, missing your usual dose is itself a trigger. Use cautiously and consistently.

3. What if the headache doesn’t respond to anything I try? An attack that is not responding to first aid or prescribed medication after two hours, or is worsening despite treatment, should prompt a call to your doctor or neurologist. Repeated treatment-resistant attacks need reassessment — the diagnosis may need to be reviewed, or a more appropriate medication found.

4. Can I prevent headaches by acting at the first sign? Yes — particularly for migraine. Many patients learn to recognise premonitory symptoms hours before the headache begins: yawning, neck stiffness, mood change, food cravings. Acting at this stage — hydrating, eating, resting, reducing stimulus — can sometimes prevent the attack from progressing to full pain. This is one of the most valuable skills I teach my patients.

A Personal Note

Good first aid for headache is not complicated, but it requires knowing your own headache patterns — what triggers it, what helps it, how it progresses, and what stage it is at when you first notice it. I encourage all my patients to develop this self-knowledge, because it makes every stage of management more effective.
