A study published in the American Journal Of Medicine conducted jointly by researchers from Beth Israel Deaconess Medical Center (BIDMC), Brigham and Women’s Hospital and the Harvard T.H. Chan School of Public Health (HSPH) concludes that drinking too much coffee
is linked with an increased risk of getting a migraine
The medical researchers found that for those who experience migraines
, one to two servings of caffeinated drinks, such as coffee
, cola and tea, were not associated with headaches on that day. However, drinking three or more were associated with higher odds of a migraine
headache on the same day, or the following day, the study suggests.
Also the concentration of the caffeine in the coffee
was also a critical factor as in some cases, one serving of concentrated expresso was sufficient to trigger a migraine
is a “moderate or severe headache felt as a throbbing pain on one side of the head”. The Migraine
Research (MRF) states that migraine
is the third most prevalent illness in the world and affects approximately 1.04 billion adults worldwide. Women are also more at prone to get migraine
compared to men.
In the cohort study, 98 adults completed electronic diaries every morning and every evening for at least six weeks. Every day, they reported the total servings of caffeinated coffee
, tea, soft and energy drinks they consumed. The participants also filled out twice daily headache reports detailing the onset, duration, intensity and medications used for migraines
since the previous diary entry.
Those in the study also detailed information about other common migraine
triggers, including medication use, alcoholic beverage intake, activity levels, depressive symptoms, psychological stress, sleep patterns and menstrual cycles.
The medical researchers compared an individual’s incidence of migraines
on days with coffee
beverage intake to their incidence of migraines
on days when they had no caffeinated drinks. This eliminated the potential for
factors such as sex, age, and other individual demographic, behavioural and environmental factors to confound the data.
The data showed that those who had more than two coffee
drinks had a 27 per cent chance of a migraine
on that day.
Baseline data indicated that participants typically experienced an average of five headaches per month and 66 per cent of them usually consumed one to two servings of caffeinated drinks daily.
Dr Elizabeth Mostofsky , lead investigator commented in a phone interview with Thailand Medical
News “Caffeine’s impact depends both on dose and on frequency, but because there have been few prospective studies on the immediate risk of migraine
headaches following caffeinated beverage intake, there is limited evidence to formulate dietary recommendations for people with migraines
Of late, many neutral medical studies also show that coffee
drinking is detrimental to one’s health in a variety of ways. There are however many other studies are directly or indirectly funded by entities with a vested interests that try to dispel these actual medical studies and state that coffee
has health benefits.
