Intermittent headaches are considered to be migraine headaches. Migraine headaches can be caused by many triggers, such as excessive stress, overexertion, sleep deprivation, insomnia, and excessive dreaming. In addition, some patients are also prone to migraine symptoms in their diet, such as drinking caffeinated beverages like coffee and strong tea. Some patients also have migraine headaches when they eat stimulating foods, spicy foods, or foods that contain a lot of tyrosine, such as cheese. Some patients can also trigger migraines due to lack of sleep or insomnia and dreaminess, and migraines tend to occur repeatedly.
