Large amounts of caffeine not good for headaches

People who consume high amounts of caffeine each day are more likely to suffer occasional headaches than those with low caffeine consumption, reports a study in the Journal of Headache Pain.

Low caffeine consumption was also associated with a greater likelihood of chronic headaches, defined as headaches for 14 or more days each month.

The results are drawn from a large cross-sectional study of 50,483 people who answered a questionnaire about caffeine consumption and headache prevalence as a part of the Nord-Trøndelag Health Survey (HUNT 2).
