A new study links heavy caffeine consumption with migraines. The study out of Beth Israel Deaconess Medical Center and Harvard University found that three or more cups of coffee or caffeinated beverages in one day can lead to headaches in people who already get episodic migraines. The link remained regardless of other factors like alcohol consumption and sleep.
Super intense migraines affects about 1.04 billion people annually. About 87-percent of Americans drink coffee per day.
