Abstract

  It is important to be aware of triggers and aggravation factors for migraine sufferers, as avoiding them in daily life can help prevent migraine attacks. The most common trigger is stress. Environmental factors include changes in the workplace or school environment. As for weather, attacks are more common during the rainy season, and attacks are often induced after low pressure. In women, it is known that migraine attacks are induced in correlation with blood estrogen levels. Furthermore, it is said that migraine attacks are more likely to be induced when foods contain substances with vasoactive effects. Frequent exposure to triggers and aggravation factors can progress to chronic migraine.
