Here’s How Much Caffeine May Trigger A Migraine

Caffeine is a funny thing when it comes to headaches– it can either cause them or help stop them. Researchers from Beth Israel Deaconess Medical Center recently found evidence suggesting that having three servings of caffeinated beverages such as coffee, tea, and soda in a day seems to be the tipping point at which caffeine might become a migraine trigger. The data showed that having three or more servings of these types of drinks was linked to a higher risk of headaches both on that day and the one following. Researchers say it’s likely an individual’s tolerance to caffeine plays a role– for example people who reported usually having one serving of caffeine per day or less had a higher risk of migraine on the days they drank even one or two caffeinated beverages. This study can’t definitively say how much caffeine is too much, but if you get migraines you might want to keep the findings in mind.
