Exercise Headaches Risk factors
Exercise headaches are more likely to occur while you’re exercising in hot weather or at high altitude. People who have a personal or family history of migraine are more likely to experience exercise headaches.
Primary exercise headaches occur most often in young men in their 20s. People with secondary exercise headaches tend to be a little older — average age 42 — and of either sex.
When to seek medical advice
If you experience a headache during or after exercise, consult your doctor — especially if it’s your first headache of this type.
Screening and diagnosis
Your doctor may recommend a magnetic resonance imaging (MRI) exam if:
* Your headaches last more than a few hours
* Your headaches strike suddenly, like a thunderclap
* You’re older than age 40
* You have other signs and symptoms, such as nausea and vomiting
In these cases, two different types of MRI can help your doctor verify that you have the harmless variety of exercise headache, rather than the type caused by a structural or vascular abnormality.
A regular MRI uses a magnetic field and radio waves to create cross-sectional images of the structures within your brain. A more specialized MRI scan — called magnetic resonance angiography (MRA) — visualizes the blood vessels leading to and inside your brain.
