If you consume caffeine on the regular, you might experience a headache when you don't get your daily fix. And it seems like the only way you can deal with the headache is by chugging a cup of coffee. But have you ever wondered why this happens on than the fact that you might be a little too dependent on caffeine? And how can you get rid of a caffeine headache?

"Caffeine narrows our blood vessels and therefore reduces blood flow to our tissues, including our brain," explains Tamar Samuels, MS, RDN, NBC-HWC, a registered dietitian, a national board–certified health and wellness coach, and co-founder of Culina Health. "When we decrease our caffeine intake after a period of regular caffeine consumption, our blood vessels dilate or expand, which is a common trigger for headaches.

Additionally, regular caffeine consumption increases the number of receptors in our brain that decrease pain known as adenosine receptors. Therefore, when we decrease caffeine consumption, we can experience more headaches as a result of fewer adenosine receptors in our brain."

The headaches can be especially tough to deal with if you're trying to cut back on caffeine. You want to limit your daily intake, but if the painful headaches are so annoying and painful, you might give in and drink a cup. And the bad news is if you are used to higher intakes of caffeine and cut back quickly, you might experience more severe symptoms of caffeine withdrawal (like headaches). "Studies have found that it may only take three days to develop caffeine dependency, but withdrawal symptoms tend to get worse after seven to 14 days of drinking caffeine," Samuels says. "Caffeine headaches have been found to last as long as nine days, but are typically worse around 20 to 50 hours after discontinuing caffeine completely."

Samuels recommends reducing caffeine gradually to prevent headaches. She suggests cutting back your intake by about 25% each week, so if you normally have two cups of coffee per day (or 14 cups per week), try decreasing your intake to 1/2 cup per day for one week, and then one cup per day the following week. Caffeinated tea can also help with cutting back. Samuels says you can try something like drinking one cup of coffee and one cup of green tea if you normally have two cups of coffee daily. And if tea isn't your thing, try doing half decaf and half regular coffee.

And Samuels has a note for people who have migraines and take medications for that: "Some migraine medications contain caffeine, which may help reduce migraine pain severity because of the aforementioned mechanisms (increase adenosine receptors and vasoconstriction)," she explains. "However, too much caffeine can also trigger migraines, so if you are a migraine sufferer, I recommended limiting your caffeine intake to 200 mg/day and keeping your consumption consistent most days to avoid withdrawal headaches."

So what else can you do to deal with a caffeine headache? Samuels shared some things that can help below.

1. Stay Hydrated

Make sure you're getting enough fluids. "Dehydration is a big trigger for headaches because it actually causes the brain to decrease in size, which triggers pain receptors," Samuels says. "I recommend having at least 64 ounces of water per day and eating hydrating food like cucumbers, tomato, and watermelon to prevent dehydration. Fluid needs vary depending on physical activity level, body size, medical conditions, pregnancy, lactation, and a number of other factors. Speak with a registered dietitian to determine the right about of fluid intake for you."

2. Get Enough Sleep

Samuels says that getting adequate amounts of restorative sleep has been found to reduce headache pain. "I recommend experimenting with a relaxing nighttime routine that doesn't involve technology to implement at least 30 minutes before your planned bedtime," she adds.

3. Try a Magnesium Supplement

Some studies have found magnesium supplements can help reduce headache pain and occurrence, Samuels explains. If you do decide to try out a supplement, be sure to chat with your doctor, a registered dietitian, or another healthcare provider who can help you figure out the right product and dosage.

4. Consider Riboflavin

You can also try a riboflavin supplement. "Riboflavin (aka B2) has also been found to decrease headache occurrence and pain severity," Samuels says.

5. Grab an Ice Pack

"Icing the head and neck area helps construct blood vessels which may help reduce pain associated with blood vessel dilation," Samuels says.
