The excessive per diem consumption of caffeinated preparations helps with appearance headaches, reveals new American research. Caffeine: 'Guilty' or 'Innocent'
Research published in the scientific journal The American Journal of Medicine by Elsevier shows that drinking 3 or more caffeinated soft drinks can trigger headaches on the same day or the next day especially in episodic migraine sufferers.
What other factors cause headaches?
The study also considered other factors responsible for causing headaches, such as alcohol, stress, insomnia, physical activity and menstruation.
"Although there are potentially conditions - such as lack of sleep - that trigger headaches, the role of caffeine is particularly complex, as it can trigger a headache, but also act as an inhibitor," explains lead researcher Elizabeth Mostowski, from the Department of Cardiovascular Epidemiology Research at Beth Israel Deacon Medical Center and from the Chan School of Public Health at Harvard University in Boston.
Over 1 billion people suffer from headaches
However, according to her, although more than 1.04 billion people worldwide suffer from headaches and about 87% of Americans consume caffeine daily, there is insufficient research to safely recommend the appropriate amount of caffeine per day for those who experience migraines.
Study
In particular, the sample of the study was 98 adults who recorded for six weeks on a daily basis in electronic diaries the amount of caffeine they consumed, as well as other possibly aggravating factors for the creation of headaches.
The incidence of headaches after consuming caffeine was then compared with those without a caffeinated beverage.
As the research findings show, 66% of people who suffered from 5 headaches per month usually consumed one or two servings of caffeinated soft drinks, while 12% more than three servings.
During the 6 weeks the participants suffered an average of 8.4 headaches. All had consumed at least one caffeine preparation with an average of 7.9 servings per week.
The next research objective is to study the effect of caffeine in the immediate hours following its consumption as well as its interaction with other factors such as sleep, stress and the environment in the creation of migraines.
