Consuming three cups of coffee every day may raise your chances of experiencing an episodic migraine, according to a new study. Coffee is a popular beverage of choice, especially in the mornings. Now researchers, suggest excessive consumption of caffeine and migraines have a strong link.
For the study, the team examined data from 98 participants who frequently suffer from episodic migraines.Each participant has documented their intake of caffeinated beverages twice a day for six weeks. They also had to make a note of other lifestyle factors and what time they experienced a migraine headache. The team then compared those notes to the days when participants did not experience a migraine.
Through the study, the team discovered participants experienced a headache on the same day of drinking too much coffee or the following day. Participants experienced an average of 8.4 headaches during the time of the study. The results were the same even after researchers took into account other factors like stress, sleep, physical activity, menstruation, and alcohol.
"Based on our study, drinking one or two caffeinated beverages in a day does not appear to be linked to developing a migraine headache, however, three or more servings may be associated with a higher odds of developing a headache," Elizabeth Mostofsky, lead author of the study, told a news portal.
Migraine is a headache disorder that affects millions of people around the world, which can be disabling. More is needed to understand how caffeinated beverages can trigger a migraine. However, some other studies suggest lifestyle factors can also play a role. This can either be skipping a meal or insufficient sleep.
"To date, there have been few prospective studies on the immediate risk of migraine headaches with daily changes in caffeinated beverage intake. Our study was unique in that we captured detailed daily information on caffeine, headache, and other factors of interest for six weeks,"Suzanne M. Bertisch, principal investigator of the study, told a news portal.
The study's findings were originally published in the American Journal of Medicine.
