Caffeine

Some individuals experience migraine relief from caffeine, but not all. While some people may find that the substance relieves their symptoms, others may find that it worsens or triggers them. In fact, caffeine itself could act as a trigger for migraine. Caffeine-containing foods and beverages include coffee, tea and chocolate.

Migraines or headaches can be brought on by consuming too much caffeine or going through caffeine withdrawal. The brain may become to expect a certain dose if it is consumed frequently. When a person's brain starts to depend on a specific level of caffeine and their intake decreases, they may experience caffeine withdrawal. Research suggests that coffee is a migraine trigger for between 6.3% and 14.5% of people. In those with a sensitivity to caffeine, the substance may also increase the intensity of headaches and make them last longer. However, the American Migraine Foundation claims that caffeine can really prevent impending migraine attacks. With occasional use, it can also relieve headaches.
