1. Hormonal changes: Oral contraceptives can increase the frequency of migraine attacks; menstruation is a common trigger or aggravating factor for migraine (“cyclical headache”); pregnancy and sexual intercourse may also trigger migraine attacks. 2.Medications: Migraine attacks can occur in certain susceptible individuals after taking cardiac pain, cardiac pain or nitroglycerin. 3.Climate change: especially when the weather turns hot, cloudy or humid. 4.Food and beverages: Most commonly alcoholic beverages (such as certain red wines), dairy products (such as cheese, especially hard cheese), coffee, foods containing nitrites (such as soup, hot dogs), certain fruits (such as citrus fruits), chocolate, yeast, artificial sweets, fermented pickled products (such as kimchi), and MSG. Some patients are afraid to ride in a car because they are afraid of the migraine attack caused by riding in a car; people who play soccer can trigger headache by putting their heads on the ball. 6.Irregular sleep: too much or too little sleep. 7. Irregular diet: a meal is missed or delayed. 8.Smoking or being in the smoke. 9.Light: flashing light, too strong light. 10.Emotion: tension, anger, depression, crying and other mood swings; some women shopping in malls or going to crowded occasions can also cause migraine attacks. Among the excitation factors, dosage, combined effects and individual differences should still be considered. For example, for sensitive individuals, eating a single orange may not cause a headache, while eating several oranges may cause a headache. In some cases, eating several oranges does not cause a headache attack, but if there is also a menstrual effect, this combined effect can cause a migraine attack.
