How to Find and Avoid Migraine Triggers

Migraine triggers aren't the reason you have migraine. In fact, nobody knows what causes migraine or why some people have migraine attacks and others don't. But your triggers are events, changes, acts, or other external or internal stimuli that make a migraine attack more likely. Some triggers will be easy for you to manage and avoid, while others may be beyond your control.

With migraine, one of the best things you can do is learn your personal migraine triggers that cause pain or other migraine symptoms. Red wine, caffeine withdrawal, stress, and skipped meals are among many common culprits, but everyone is different. You may notice that it takes more than one trigger to lead to an attack. 

The first step to avoiding your triggers is to figure out what they are. You can do this by tracking your migraine symptoms in a notebook, diary, or smartphone app. Note what you were doing before and when your migraine symptoms came on. What had you eaten? Were you dehydrated? How much sleep did you get the night before? Did anything stressful, exciting, or otherwise important happen that day? These are key clues to learning about your migraine attacks and their triggers.

How Do Migraine Triggers Work?

An easy way to think of a trigger is that it’s like a light switch: When it's flipped on, a process starts in your brain that can end in pain and other migraine symptoms. Another way to think about it is that you have a migraine threshold. When your triggers add up to a certain level, you'll get your familiar migraine symptoms.

But it's not as simple as cause and effect. Something that triggers a migraine attack one day may not have the same effect on you another day. You're probably more likely to have a migraine episode if more than one of your triggers is present. For example, missing lunch one day might be OK. But if you miss lunch and didn't get enough sleep the night before, you may be more likely to get a migraine attack.

Types of stress triggers

Triggers vary from person to person but are often related to stress. They can be:

  • Physical, such as dehydration, sleep loss, or hormone changes
  • Emotional, such as anxiety
  • Environmental, such as changes in the weather

Common Migraine Triggers

Everyone is different when it comes to migraine triggers. Some common ones to watch for include:

  • Stress
  • Menstrual periods
  • Changes in your normal sleep pattern
  • Lack of sleep
  • Extreme fatigue
  • Certain foods, such as aged cheese or processed snacks
  • Certain drinks, such as those with alcohol or caffeine
  • Food additives, such as artificial sweeteners or monosodium glutamate (MSG)
  • Too much caffeine or withdrawal from it
  • Alcohol
  • Skipping meals or fasting
  • Changes in the weather or barometric pressure
  • Exercise
  • Physical strain
  • Smoking
  • Bright, flickering lights
  • Loud sounds
  • Strong smells, such as perfume or paint thinner
  • Certain medications, such as oral contraceptives or vasodilators
  • Dehydration
  • Hormonal changes

Tips to Avoid Migraine Triggers

Pay attention to what you eat and drink. If you get a migraine attack, write down the foods and drinks you had before it started. If you see a pattern over time, stay away from that item.

Eat at regular intervals. Following your normal routine is key to avoiding migraine attacks. Don't skip meals or change your snacking or meal times too much from one day to the next.

Curb the caffeine. Daily caffeine can raise the risk for migraine in some people. If you’re one of them, slowly cut down on caffeine. (That’s because suddenly missing your morning coffee can trigger a migraine attack.) If a cup of coffee each morning isn't one of your migraine triggers, it's OK to stick to that, too.

Be careful with exercise. Everyone needs regular physical activity. It's a key part of being healthy. But it can be a migraine trigger for some people. If you're one of them, you can still work out. Ask your doctor what would help or see if they can refer you to a personal trainer who can help you find a good routine.

Get regular shut-eye. If your sleep habits are disrupted, or if you're very tired, it can make a migraine episode more likely.

Downsize your stress. There are many ways to do it. You could exercise, meditate, pray, spend time with people you love, take a walk in nature, and generally do things you enjoy. If you can change some of the things that make you tense, set up a plan for that. Counseling and stress management classes are great to try, too. You can also look into biofeedback, where you learn how to influence certain things (such as your heart rate and breathing) to calm down stress.

Stay hydrated. Dehydration is a trigger for many people. Carry a water bottle with you and make sure you're getting enough fluids every day.

Stay away from sensory stimulants. If bright lights, strong scents, or loud sounds bother you, take steps to avoid them as much as you can. Wearing sunglasses, earplugs, or noise-canceling headphones may also help.

Avoid the heat. Weather changes can be a trigger you can't always control. But you can take steps to limit your exposure. If the summer heat bothers you, for example, try to avoid spending time outdoors during the hottest part of the day.

Avoid taking medicine too much. It might seem counterintuitive, but taking medicine to help with your migraine attacks too often can lead to what's known as medication overuse headaches. If you find yourself in this vicious cycle, talk to your doctor or migraine specialist about a treatment plan that may help you avoid turning to over-the-counter or other medicines too often.

Migraine Trigger Foods

Some foods can be a migraine trigger, but it's not as common as many people think. The evidence for links between migraine and certain foods isn't strong. But some foods that might trigger migraine include:

  • Foods that have tyramine in them, such as aged cheeses (such as blue cheese or Parmesan), smoked fish, and Chianti wine
  • Alcohol, especially red wine
  • Caffeine, which is in coffee, tea, colas, and other sodas
  • Foods made with nitrates, such as pepperoni, hot dogs, and lunch meats
  • Dried fruits
  • Potato chips
  • Pizza, peanuts, and chicken livers
  • Bread and other baked goods with yeast, such as sourdough bread, bagels, doughnuts, and coffee cake
  • Chocolate
  • Cultured dairy products (such as yogurt and kefir)
  • Fruits or juices such as citrus fruits, dried fruits, bananas, raspberries, red plums, papayas, passion fruit, figs, dates, and avocados
  • Nuts and nut butters
  • Olives
  • Soy products (miso, tempeh, soy sauce)
  • Tomatoes
  • Vegetables such as onions, pea pods, some beans, corn, and sauerkraut
  • Vinegar
  • Food additives, such as artificial sweeteners or MSG

Takeaways

Migraine triggers are events, stimuli, or other factors that make it more likely you'll have a migraine attack. It often takes more than one trigger to lead to an attack, but everyone is different. Along with treatment, learning your migraine triggers and taking steps to avoid or limit them as much as you can is one way to help you reduce your attacks.
