Caffeine is something that on average 90% of Americans enjoy, but it can also be a headache trigger or headache inhibitor. Caffeine is all around us,  and can be found in a number of beverages, chocolate and even in some popular over-the-counter and prescription pain relievers, but how is it affecting our heads?

The Buzz on Caffeine

Before a headache or migraine, blood vessels tend to enlarge, but caffeine has “vasoconstrictive” properties that cause the blood vessels to narrow and restrict blood flow, which can aid in head pain relief. When caffeine is added to the combination of acetaminophen and aspirin, the pain relieving effect is increased by 40%. If you feel a headache coming on, a cup of joe might lessen the severity of your symptoms.

On the other hand, though caffeine does not directly cause headache, too much of the substance can trigger “caffeine rebound.” A caffeine rebound headache occurs from withdrawals of caffeine after a sufferer continually consumes too much of it. Though the physical side effects can be severe, only 2% of the population suffers from caffeine rebound.

Although most headache sufferers can consume up to 200 mg. per day, the NHF advises patients with frequent headaches to avoid daily use. But this doesn’t mean you have to cut your caffeine off, try slowly decreasing your intake, and remember it’s always best to enjoy in moderation.
