Exercise and Migraine: What a 1,828-Person Study Found

Exercise and Migraine: Background

People with migraine are often told to exercise regularly. Many of them have also had a run, a spin class, or a soccer game end in a migraine attack. Both experiences are real, but there has been limited data on how common each one is or which patients tend to fall into which group.

A study published in October 2026 in the journal Headache asked 1,828 patients at a university hospital headache clinic in Seoul, South Korea, how exercise affects their headaches. The answers split into clear groups, and the patients in each group looked different in a few consistent ways.

If you have wondered whether your own reaction to exercise is unusual, the short answer from this study is that it is not. Roughly half of the patients noticed no link at all, and the rest were split almost evenly between people who said exercise triggers attacks and people who said it helps.

How the Study Was Done

This was a cross-sectional survey. Patients with migraine who visited the clinic between October 2022 and December 2024 filled out a structured questionnaire about exercise and headache. Based on their answers, each person was placed in one of four groups that did not overlap.

The researchers then sorted patients by monthly headache days and compared the groups.

They also looked at age, anxiety, and allodynia, using statistical models that account for several factors at once (an adjusted analysis).

What the Study Found

Here is how the 1,828 patients answered.

So about one in four patients saw exercise as a trigger, and about one in four saw it as something that helps an existing headache. Because the groups were mutually exclusive, the study cannot tell us how many people experience both depending on the day or the type of exercise.

Who Was More Likely to Report Exercise as a Trigger

Four factors were independently linked to exercise-related provocation: younger age, higher headache frequency, allodynia, and self-reported anxiety.

Headache frequency showed a clear step pattern. Compared with people who had low-frequency episodic migraine, people with high-frequency episodic migraine had 1.71 times the odds of reporting provocation, and people with chronic migraine had 2.50 times the odds.

Who Was More Likely to Report Improvement

Headache improvement during exercise was linked to older age, chronic migraine, and self-reported anxiety. People with chronic migraine had 1.42 times the odds of reporting improvement compared with people with low-frequency episodic migraine, and people with anxiety had 1.58 times the odds.

Two of these findings overlap with the trigger group. Chronic migraine and anxiety were each associated with both provocation and improvement. That sounds contradictory, but it may mean that people with heavier migraine burden and anxiety notice exercise effects more in either direction, while people with infrequent attacks are more likely to report no connection at all.

Factors Linked to Each Response

The numbers in parentheses are 95% confidence intervals. None of them cross 1.0, which means each association was statistically reliable in this sample.

How This Fits With Earlier Research

The trigger rate in this study lines up with earlier work. In a 2013 study of 103 patients at a Dutch headache clinic, 38% said exercise had triggered a migraine attack at some point in their lives. More than half of those patients had given up the sport that set off their attacks, and they were more likely to have neck pain as the first symptom of their usual attacks.

On the prevention side, a 2011 randomized trial from Sweden compared 40 minutes of exercise three times a week with a relaxation program and with topiramate (Topamax) in 91 adults with migraine. After three months, all three groups had a similar drop in attacks, a little under one attack per month. The authors concluded that exercise may be an option for people who do not benefit from, or do not want, daily preventive medication.

Exercise is one of several lifestyle factors that interact with migraine. Our posts on sleep duration and migraine and on choosing the best type of exercise with migraine cover related ground, and the AAN and AHS prevention guideline explains where medication fits in.

Limitations to Keep in Mind

• It measures perception. Patients reported what they believe exercise does to their headaches. That is useful, but it is a self-reported view, not a measured response to a controlled exercise session.
• It is a snapshot. A cross-sectional design shows associations, not cause and effect. For example, it cannot tell us whether allodynia makes exercise more likely to trigger attacks or whether both reflect the same underlying sensitization.
• One clinic, one country. All patients came from a single headache clinic in Seoul. People who seek specialist care usually have more severe migraine than the general population, so the results may not apply to everyone.
• Single-answer groups. Each person was placed in one group, which leaves out people whose response varies by activity, hydration, sleep, or timing in the menstrual cycle.

What This Means for People With Migraine

The main point from the authors is that a single exercise recommendation does not fit every patient with migraine. The study supports basing exercise advice on how each person responds.

• Write down what happens. Noting the activity, intensity, duration, and whether a migraine attack followed within the next day can show whether exercise is a real trigger for you. A migraine tracker journal makes this easier to bring to an appointment.
• Bring it up with your clinician. If exercise reliably triggers attacks, say so. The migraine appointment summary sheet has space for triggers like this.
• Look at the bigger picture. Since provocation was more common with frequent attacks and allodynia, better overall migraine control may be part of the conversation, not only changes to the workout itself.
• Do not assume exercise is off limits. A quarter of patients in this study said exercise eased their headaches, and earlier trial data show regular aerobic exercise can reduce attack frequency for some people.
