Consumption of Three or More Caffeinated Beverages May Trigger Migraine

Migraines are a recurring type of headache that causes moderate to severe pain that is throbbing or pulsing. They may be accompanied by nausea and sensitivity to light. According to a new study, consuming three or more caffeinated beverages daily may trigger a migraine in those susceptible to migraine headaches.

Ninety-eight
adults who suffer from periodic migraines participated in the study.
Participants filled out electronic diaries two times a day for six
weeks in which they recorded caffeinated beverage intake, other
lifestyle factors, and the timing and characteristics of each
migraine headache. The researchers compared migraine incidence on
days with caffeinated beverage intake to migraine incidence on days
when no caffeinated beverages were consumed.

Participants
were found to suffer an average of five migraines per month. 66% of
them consumed one to two caffeinated beverages per day, and 12%
consumed three or more. The researchers found that consuming three or
more caffeinated beverages per day increased the risk of a migraine.

The
study was conducted by researchers from the Harvard T.H. Chan School
of Public Health. It was published online ahead of print on August 6,
2019 in The
American Journal of Medicine.
