What Causes Migraines?

Migraines are one of the most common types of headaches. Over 35 million Americans suffer from migraines. In this article, we will discuss the potential causes of migraines and what you can do to prevent them.

What is the difference between a migraine and a headache?

A headache is generally classified as any pain or discomfort that occurs in the head, face, or neck. Headaches can be caused by many different things, including stress, tension, dehydration, hunger, eye strain, and sinus infections. A migraine is a type of headache that is often more severe and is accompanied by other symptoms, such as nausea, vomiting, and sensitivity to light and sound.

What causes migraines?

There is no one answer to this question as the cause of migraines can vary from person to person. However, there are some potential triggers that have been identified. These include:

Hormonal changes

Hormone fluctuations can trigger migraines in some people, especially women. This is because, during certain times in the menstrual cycle, levels of estrogen drop sharply. This can cause a change in the brain chemicals and lead to migraines.


Migraines can be triggered by stress, both physical and emotional. When you are under stress, your body releases stress hormones, such as cortisol. These hormones can change the way your brain functions and cause migraines.

Certain foods

There are some foods that are more likely to trigger migraines in certain people. These include aged cheeses, chocolate, caffeine, alcohol, and processed meats.

Sensory overload

For some people, bright lights, loud noises, and strong smells can trigger migraines. This is because sensory stimulation can overwhelm the brain.

What can you do to prevent migraines?

There is no one-size-fits-all solution for preventing migraines. However, there are some things that you can do to lessen the chances of having a migraine. These include:

Staying hydrated

Dehydration is a common trigger for migraines. Make sure to drink plenty of water throughout the day, especially if you are exercising or sweating.

Eating regular meals

Missing meals or going for long periods of time without food can trigger migraines. Try to eat three regular meals each day and snacks as needed.

Try CBD Oil

CBD oil is a natural remedy that has been shown to help reduce migraines. CBD oil works by interacting with the body’s endocannabinoid system. This system is responsible for regulating pain, inflammation, and sleep.

Exercise can help to reduce stress and tension. Aim for 30 minutes of moderate exercise on most days of the week.

Manage stress

Try to find ways to manage your stress, such as yoga, meditation, or deep breathing exercises.

Avoid triggers

Keep a migraine diary to help identify your triggers. Once you know what triggers your migraines, try to avoid them.


As you can see, there are many potential causes of migraines. However, there are also things that you can do to prevent them. If you are regularly experiencing migraines, talk to your doctor about ways to manage them.
