Another study, this time published in The American Journal of Medicine, addresses the issue of taking in too much coffee every day. According to the new research, drinking too much coffee every day can prove to be a “potential trigger for migraine on that day or the following day,” as reported in the study.
Elizabeth Mostofsky, a researcher at the Harvard TH Chan School of Public Health and lead author of the study, explains the results: “According to our study, drinking one or two caffeinated drinks in one day does not seem to be linked to the development of a headache, however, three or more portions may be associated with a greater probability of developing a headache.”
The researchers used results obtained with 98 adults who suffered from episodic migraine. The same participants had to report various information including daily intake of coffee or caffeinated beverages as well as other information regarding their lifestyles and migraine episodes.
On average, five people had headaches a month. 66% of them consumed one or two servings of beverages that contained caffeine every day while 12% consumed three or more servings. During the study period examined (six weeks 2016-2017), participants reported having on average 8.4 headaches and all reported having caffeinated beverages in at least one day during the study with an average of 7.9 portions each week.
The results, according to the researchers, showed that the impact of caffeinated beverages on the risk of headaches on a given day was only evident when taking three or more portions of caffeinated beverages that day.
