Insufficient sleep is often cited as a trigger for acute migraine attacks. Excessive sleep is a frequently reported trigger as well. Jet lag and changes in your work schedule can also be linked to the onset of migraine. Insomnia is the most common sleep disorder associated with chronic migraine.
(Migraine headaches are sometimes called vascular headaches. Vascular means having to do with the blood vessels.) These headaches can also suddenly arise in some people when they do not get enough sleep or food. Common triggers of migraine headaches include heat, stress, and lack of sleep or food. Not every headache sufferer is sensitive to these triggers, but virtually all persons with migraine headaches (called migraineurs) have some environmental trigger.
