Exercise headaches occur during or after sustained, strenuous exercise.
Some activities associated with exercise headaches include running, rowing, tennis, swimming and weightlifting.
Doctors divide exercise headaches into two categories. Primary exercise headaches are usually harmless, aren't connected to any underlying problems and can often be prevented with medication. Secondary exercise headaches are caused by an underlying, often serious problem within the brain — such as bleeding or a tumor — or outside the brain — such as coronary artery disease.
Symptoms
Primary exercise headaches:
- Are usually described as throbbing
- Occur during or after strenuous exercise
- Affect both sides of the head in most cases
Secondary exercise headaches may causethe same symptoms as primary exercise headaches, also:
- Vomiting
- Loss of consciousness
- Double vision
- Neck rigidity
Primary exercise headaches typically last between five minutes and 48 hours, while secondary exercise headaches usually last at least a day and sometimes linger for several days or longer.
If you experience a headache during or after exercise, consult your doctor. Call your doctor right away if the headache begins abruptly or if it's your first headache of this type.
The exact cause of primary exercise headaches is unknown. One theory is that strenuous exercise dilates blood vessels inside the skull.
Secondary exercise headaches are caused by an underlying problem, such as:
- Bleeding in the area between the brain and the thin membranes that cover the brain (subarachnoid hemorrhage)
- Abnormalities in a blood vessel leading to or within the brain
- Cancerous or noncancerous tumors
- Obstruction of cerebrospinal fluid flow
- Sinus infection
You may be at greater risk of exercise headaches if you exercise in hot weather, exercise at high altitude, have a personal or family history of migraine.
