OsteoVIf you live with migraine you have almost certainly been told to get more sleep. It is well meant and it is not exactly wrong, but as advice goes it is too blunt to be much use and it hints that the broken nights are something you have chosen. What the research actually says is more interesting than that, and rather more forgiving.
The loop runs in both directions
Sleep and migraine are described as bidirectionally linked, which is a formal way of saying each one makes the other worse. People with migraine are more likely to have insomnia and poorer sleep quality than people without it, attacks often begin during the night or are there waiting on waking and the days after an attack are rarely restful. Running the other way, a disturbed or shifted sleep pattern is one of the most commonly reported triggers.
Once you are inside that loop it becomes almost impossible to say which end started it and honestly it is not always a useful question. What is worth saying plainly is that being stuck there is not a failure of discipline. Many of the same brain regions and chemical messengers are involved in both sleep regulation and migraine, so a brain that is prone to one is often prone to the other.
It may not be the number of hours
This is the part that surprises people. A prospective study of 98 adults with episodic migraine, which tracked six weeks of sleep using wrist actigraphy alongside twice-daily diaries, found that short sleep of six and a half hours or less was not associated with a migraine that day or the next. What did show an association was low sleep efficiency, which is simply the proportion of time in bed that you actually spend asleep. Nights rated as inefficient came with around 39 per cent higher odds of an attack the following day.
One study of that size does not settle the question and the findings need replicating, but it fits what people describe in clinic. The night before an attack is often not a short night. It is a broken one, with three or four surfacings, a long stretch staring at the ceiling at 4am and a morning that arrives feeling like it never really got going.
Your body clock, and the Sunday lie-in
The timing of sleep does a lot of work here. Migraine risk is tied to the circadian rhythm and research suggests it is not the total each night that influences attacks so much as a shift away from your usual routine. That includes shifts in the generous direction. A long lie-in confuses the following night, which makes the next bedtime harder, so the whole week can tilt from there.
The Migraine Trust describes this misalignment between your body clock and your actual schedule as social jetlag and people with migraine seem more likely to sit at the extreme ends of the morning lark and night owl spectrum, which makes the mismatch more likely in the first place. Consistency, in other words, tends to beat catching up.
If you wake with the attack already there
Morning attacks are common and they are worth mentioning to your GP rather than absorbing. Regularly waking with headache can prompt a check for other causes such as sleep apnoea, raised blood pressure or hypnic headache. It may also change which acute medicine suits you, since something faster acting is often more practical when the pain has a head start. Do keep an eye on frequency, as acute medication taken on more than around two days a week can tip into medication overuse headache.
What is worth changing first
- Anchor the wake time, not the bedtime. A steady getting-up time, including at weekends, is the single most reliable way to hold the rhythm steady.
- Aim for a continuous night rather than a long one. Cool, dark and still. Late alcohol is worth being honest about, since it gets you to sleep and then fragments the second half of the night.
- Get outside early. Morning daylight is the strongest signal your internal clock has to work with.
- If you lie awake most nights, ask about CBT for insomnia. Recent reviews suggest sleep-focused treatment of this kind may reduce migraine frequency where insomnia is also present, which is a more promising route than another tracker.
A word on tracking. Monitoring sleep helps some people find a rhythm but it tips easily into anxious scrutiny and worrying about your sleep score at midnight is not a neutral act. If it is winding you up, stop.
One thing I would add from an osteopathic perspective, offered as clinical judgement rather than settled evidence: when someone tells me they cannot get comfortable enough to stay asleep, it is worth looking at the neck and jaw before assuming the problem is purely a sleep one. Persistent neck discomfort and night-time clenching both disturb sleep and both are things that assessment can do something about.
When to seek urgent care
See a doctor promptly, or call 999, if you have a sudden, severe "thunderclap" headache, a headache with fever and a stiff neck, new weakness, numbness or confusion, or a headache after a head injury. New or changing headaches always deserve medical assessment.
If your headaches and your sleep have been feeding each other for a while, a full assessment can help work out which thread to pull first. You are welcome to book an appointment or get in touch.
