Increasing your daily caffeine intake could trigger migraines, especially if you are prone to headaches already, suggests a new study.
From March 2016 till October 2017, the researchers at Harvard University analysed 98 adults- 12 men and 86 women- who experienced episodic migraines, which can also be defined as experiencing 0-14 headaches every month. During the span studied, the researchers recorded the intake of caffeinated beverage, other lifestyle aspects as well as the characteristics and timing of every migraine headache of each participant in a day.
They then compared the occurrence of migraines of the participant who drank caffeinated beverages with the same person on days he/she didn’t drink caffeinated beverages. The findings showed that the participants that drank 1 to 2 caffeinated beverages throughout the day did not experience more of migraines on an average than compared to what they did experience on the days with no intake. However, when they drank 3 or more of such caffeinated beverages, the incidence of migraine went up on the same day.
According to the researchers, there wasn’t any nonlinear relationship between migraine headache and intake of caffeinated beverage on the same day. This shows that consuming high levels of a caffeinated beverage could trigger migraine headaches, they added.
