Some people are moderates and who can not help it. The coffee, as well as a rite, a pause may be a need like the cigarette since, in some way, caffeine creates a kind of addiction. But caffeine may precipitate sudden headache occasionally. Yes, no, maybe ... I rather conflicting suggestions emerging from a new study conducted by Norwegian researchers at the Norwegian University of Science and Technology.

Study coordinated by dr. Knut Hagen, Faculty of Medicine, have been analyzed data collected from 50,483 people who had to complete a questionnaire about their consumption of caffeine and on episodes of migraine.

The data were part of a larger study called the North-Trøndelag Health Survey (HUNT 2) conducted between the years 1995-1997. The analysis has highlighted as among the people who reported the highest consumption of caffeine there was an incidence of cases of sudden and occasional headaches.
But at the same time, and surprisingly, among those who instead took low doses of caffeine there was an incidence of cases of chronic migraine.

The Hamlet question that the researchers have set themselves and then was whether caffeine makes good or bad for your head. Anyway, it is also true that many common medicines containing analgesics just caffeine.

Many studies have also shown controversial results: some emphasize the fact that too much caffeine causes headaches, others have found no link.

What appears from this new study is that a link between headaches and a large intake of caffeine (500 mg) per day by people showed only 18% of cases, compared with those taking only 125 mg per day of caffeine.
However, warn the researchers, since this is a cross-sectional study that is part of a larger study that was not focused on finding a link caffeine / headache, it becomes difficult to establish a connection and determine that a high consumption of caffeine cause sore occasional head. As it becomes even more difficult to explain why just the chronic headache is not widespread among the major consumers of caffeine.

What, when, they feel they suggest is that people can plug their headaches intake of caffeine, should tone down their use. While those who suffer from chronic headache may benefit from greater use of caffeine, but this is only a hypothesis.
The study was published in the journal: "Journal of Pain."
