Should I go to work the day after a migraine?

Short answer

The day after is not "after". The postdrome — the phase that follows the pain — is part of the attack, and it affects roughly 80% of people. Most recover within 24 hours of the pain ending, but during that window fatigue, difficulty concentrating and a stiff neck are the norm, and measurable cognitive impairment can persist past the pain. So the honest answer is that you can usually work, and that you will probably work at reduced capacity — which is worth planning for rather than discovering at 11 a.m.

If you are not sure whether what you get is migraine at all, that changes everything downstream: take the 2-minute survey.

Note: this article explains what is known about the migraine postdrome and is not medical advice. Information about workplace protections refers to the United States and may differ where you live.

The day after is not a hangover you invented

People with migraine describe the day after in almost identical language — wrung out, foggy, a beat behind, like the volume of the world is slightly wrong. And they describe apologising for it, because the pain has gone and there is no longer anything visible to point at.

There is a formal name for it. The international classification of headache disorders defines the postdrome as a symptomatic phase lasting up to 48 hours after the pain of a migraine attack resolves, with fatigue, elated or depressed mood and cognitive difficulties among its common symptoms. It is not a hangover from the attack. It is the last phase of it.

The numbers back up how ordinary this is. In an electronic diary study of 120 people, 81% reported at least one non-headache symptom in the postdrome, most commonly tiredness, difficulty concentrating and a stiff neck. A more recent study of 631 people found 80.7% reported at least one postdromal symptom when prompted, and 66.7% unprompted.

So when you say you are not right the day after, you are describing something that happens to four people in five. You are not imagining it, and it is not your fault that it does not show from the outside.

How long it lasts

The same diary study found that in 93% of attacks, people had returned to normal within 24 hours of the pain resolving spontaneously. Only 7% ran longer. Notably, the duration did not vary significantly with which acute medication was taken, or with how severe the headache had been — so a mild attack can leave you flattened, and a bad one can clear cleanly. If you have been treating your postdrome as a punishment proportionate to the attack, it does not work that way.

One more useful distinction from the classification: after an attack, a low-grade non-pulsating headache without other symptoms may persist, but that residual ache is not considered part of the attack itself. If you are still getting the full picture — nausea, light sensitivity, throbbing — that is a continuing or recurring attack, not a postdrome, and it may need treating as one.

What is actually impaired

This is the part that matters for the work question, and it is measurable rather than a matter of feeling.

A 2024 review of migraine and cognitive dysfunction found that while subjective reports of impairment are consistent, objective testing varies — but many studies show worse cognitive performance during the attack compared with controls, and this can persist into the postictal period. The domains involved include attention, memory and processing speed; studies during attacks have documented declines in processing speed, working memory, visuospatial ability, sustained attention and verbal learning.

The same review notes that cognitive dysfunction has been reported as the second largest cause of disability in migraine, after pain.

Two honest caveats. Whether impairment continues into the pain-free interval between attacks is understudied and the findings conflict. And "measurable on a neuropsychological test" is not the same as "will visibly affect your work" — the size of the effect varies between people and between tasks.

But the practical implication is solid enough: on the day after an attack, the work that will suffer is the work that needs sustained attention, quick processing, or holding several things in your head at once. The work that will be fine is the work that is routine, familiar and unhurried.

What the evidence says about working through it

Here is a number worth knowing, because it reframes the question entirely.

In a survey of 28,902 US workers, headache was the most common pain condition causing lost productive time, affecting 5.4% of the workforce in a two-week period, ahead of back pain. Workers with headache lost an average of 3.5 hours a week. And the crucial finding: 76.6% of the lost productive time was explained by reduced performance while at work, not by absence.

A migraine-specific diary study of 122 employed people found the same shape. Over three months they missed only 1.1 work days, of which 0.7 were due to migraine — but when at work with a migraine headache, their work effectiveness was reduced by 41%.

So the dominant pattern in migraine and work is not people staying home. It is people at their desks, working at a fraction of their capacity, and counting that as having shown up. The day after an attack is squarely in that territory.

That does not mean you should stay home. It means the real choice is not "go in or don't" — it is "go in and do which work".

A more useful question than "should I go in?"

Try these instead.

What does today actually require? A day of routine execution is very different from a day with a negotiation, a presentation, or code that will be hard to debug. If the demanding item can move by 24 hours, moving it costs less than doing it badly.

Am I still in the attack? Nausea, light sensitivity, throbbing that returns when you stand up — that is not postdrome. Treat it as a continuing attack and treat it early rather than waiting to see.

What would reintroduce a trigger? This is where a rushed return genuinely does carry risk, though not in the way it is usually described. We could find no evidence that resuming activity too fast triggers another attack — that claim circulates widely and rests on nothing we could verify. What is documented is that the established triggers are easy to walk straight back into: stress, reported by 79.7% of people with migraine; sleep disruption, 49.8%; not eating, 57.3%; bright light, 38.1%. A day that starts with a skipped breakfast, a fluorescent office and a compressed deadline is stacking three of them.

There is also the let-down pattern to be aware of. In a diary study, a decline in perceived stress from one evening to the next was associated with migraine onset over the following 6 to 18 hours, with odds ratios of 1.5 to 1.9. Practically: pushing hard through the recovery day and then collapsing is a shape worth avoiding, not because exertion is dangerous, but because the drop afterwards is a documented trigger in its own right.

Can I do this day differently rather than not at all? Usually yes, and that is the answer most people never consider.

Postdrome, or the attack coming back?

This distinction is worth getting right, because the two need completely different responses and they are easy to confuse on a groggy morning.

Postdrome is fatigue, difficulty concentrating, a stiff neck, mood that is flat or oddly elevated, and often a dull residual ache. What it is not is the full picture. The classification is specific that a low-grade, non-pulsating headache without accompanying symptoms may persist after an attack, and that this residual ache is not counted as part of the attack itself.

A recurring or continuing attack brings the accompanying symptoms back with it: throbbing rather than pressing, pain that worsens when you move or bend, nausea, and sensitivity to light and sound. If those return, you are not recovering — you are in another attack, and the guidance to treat at the first sign of pain applies again. Waiting on the assumption that it is "just the hangover" is the most common way people end up treating at peak pain instead of early.

The practical test is the accompanying symptoms, not the intensity. A mild throbbing headache with nausea is more likely to be an attack than a moderately unpleasant pressing one without.

What your own data can show

The day after is one of the few situations where a wearable earns its place, because the recovery is visible.

What to look at. Resting heart rate that is still above your usual range. Heart rate variability below your own baseline — often still low the morning after the pain has gone. Sleep that was fragmented or shorter than normal during the attack. If you track these routinely, you will start to see something useful: how long your own recovery actually takes, as opposed to how long you assume it should.

That personal number is the point. If your data consistently returns to baseline by the second morning, that is a reasonable planning assumption. If it consistently takes three days, that is worth knowing before you commit to a demanding Thursday.

Welltory measures heart rate, heart rate variability and sleep from your phone or wearable, so your own recovery curve after an attack becomes a number instead of a guess.

What it cannot do. No wearable measures cognitive function, and none can tell you whether you are safe to do a specific task. It also cannot diagnose migraine. Treat it as a recovery curve, not a verdict.

Not sure your headaches are migraine?

Roughly half of migraine has never been formally diagnosed, and without the diagnosis none of the treatment options — early acute treatment, prevention, workplace accommodations — are really on the table. The survey takes two minutes: start the survey.

How to make the day after workable

Practical, and ordered by how much they help.

• Front-load the easy work. Do the routine, familiar tasks in the morning and leave anything requiring sustained concentration until you can tell how the day is going.

• Move one thing. Not the whole day — one item. The meeting that needs you sharp, or the decision that will be expensive to get wrong.

• Eat on time. Not eating is among the top three reported triggers, and the day after an attack is a day people forget to eat.

• Deal with the light. The American Migraine Foundation's workplace guidance suggests fluorescent light covers, a desk lamp instead of overhead lighting, and a blue-light filter or filtering glasses.

• Deal with the noise and smells. Noise-cancelling headphones, seat reassignment away from where colleagues heat food, and asking about scented air fresheners and soaps are all on the same list.

• Work from home if you can. The same guidance notes it gives more control over the environment and can reduce the number of sick days taken during or after attacks.

• Take breaks deliberately rather than pushing straight through and crashing.

• Do not skip your usual sleep window to catch up on what the attack cost you. Schedule change is its own trigger.

Talking to your employer

Most people never have this conversation, and the reason is usually that migraine does not look like anything from the outside.

The American Migraine Foundation publishes a guide specifically for this, and its structure is worth using. Know your migraine first: track your attacks and their effect on your work performance, so the conversation runs on specifics rather than impressions. Know your rights: in the United States, if migraine substantially limits one or more major life activities, you may be protected under the Americans with Disabilities Act, and the Department of Labor's Job Accommodation Network is the practical resource for what accommodations look like. Then make a specific request — a named change, not a general appeal for understanding.

The framing that works best is the productivity one, and it is honest. Most of what migraine costs an employer is not absence, it is reduced performance at work — 76.6% of lost productive time in that large US survey. An accommodation that recovers part of that is a better deal for both sides than a sick day, and it is a reasonable thing to say out loud.

How to bring this up with your doctor

The day-after question is a symptom of a bigger one: how often is this happening, and is it being treated adequately?

What to bring. A record covering four to eight weeks: attack dates, how long the pain lasted, how long the day-after phase lasted, and how many work days were affected — separating days missed from days worked at reduced capacity. That second number is usually the larger one and almost never gets reported.

What to say instead of "I get migraines". "I have had five attacks in eight weeks. The pain lasts about a day, and I lose most of the following day to fatigue and difficulty concentrating. I have missed two days of work and worked badly on about nine." That describes a burden. "I get migraines" does not.

What to ask for.

• Whether preventive treatment applies to you. The American Headache Society's thresholds are tiered: prevention should be offered at six or more headache days a month with no disability, four or more with some disability, and three or more with severe disability, and considered at lower counts. If your postdrome routinely costs you a working day, that belongs in the disability side of the assessment — say so explicitly.

• What to take at the first sign of an attack. The guidance is to treat at the first sign of pain to improve the chance of becoming pain-free and reduce disability, and one trial found treating while pain was still mild produced a substantially higher pain-free rate at two hours.

• Whether the number of days you take acute medication is safe. Medication-overuse headache starts at 15 or more days a month for ordinary painkillers and 10 or more for triptans, ergots, opioids and combination painkillers.

• Whether they will document the impact for a workplace accommodation request, if you plan to make one.

If you are brushed off. Ask for it to be written down: "attacks and postdromal disability discussed, preventive treatment not offered because…". It turns a shrug into a recorded clinical decision.

When the day after is not just a postdrome

Get urgent advice if the day after brings any of the following, rather than assuming it is the usual recovery:

• A headache that reaches maximum intensity within seconds.

• Weakness, numbness, confusion, trouble speaking, or vision changes that do not resolve.

• Fever, or a stiff neck with fever.

• A clear change in the pattern of attacks you have had for years.

• A first attack starting after age 65.

• Any of this following a head injury.

How we made it

Written from the International Classification of Headache Disorders (3rd edition) for the definition of the postdrome, diary studies of postdromal symptoms, a 2024 review of cognitive dysfunction in migraine, population studies of lost productive time at work, and workplace guidance from the American Migraine Foundation. Where a widely repeated claim has no evidence behind it — that returning to activity too soon triggers another attack — we say so rather than passing it on.
