Is Stress Causing Your Migraines?

With approximately 80% of migraine sufferers citing stress as a trigger, we explore how stress can cause migraine headaches and what’s the best plan of action to prevent and relieve the painful symptoms.

Anyone who’s had the unfortunate experience of a migraine knows that they are more than just a headache, progressing through multiple stages of different symptoms, and sometimes lasting multiple days. Although there are effective treatments to relieve the symptoms of migraines when they do occur, it’s preferable to examine and limit any lifestyle and environmental factors that could be leading to the development of your migraines. One such facet of our lives that has a number of knock-on effects on our health is our stress levels, and whilst the ultimate causes of migraines are still being researched, it’s no surprise that high stress is likely to be a contributing factor. In this article, we’ll explore the relationship between stress and migraines, identify some methods to limit these disturbances, and outline effective medication to take if you anticipate a migraine coming on.

What is a Migraine?

A migraine is a common medical condition affecting approximately 20% of women, and 7% of men[1]. Typically, migraines cause a throbbing headache that in most cases only affect one side of the head, but set themselves apart from regular headaches by also causing nausea and vomiting, as well as visual and other sensory disturbances. They are often characterised by a four-phase progression:

  1. Prodrome - appearing one to two days before the “Attack” phase, subtle bodily changes such as frequent yawning, increased thirst, or abnormal food cravings can serve as a precursor to your migraine headaches.
  2. Aura - occurring before or during the “Attack” phase, this stage affects the nervous system, most commonly causing visual hallucinations such as seeing flashes of light or bright spots. You may also experience pins and needles in the arms and legs, difficulty speaking, or auditory hallucinations amongst others. Whilst these typically last for a few minutes, they may continue for up to an hour.
  3. Attack - also known as the “Pain” phase, this stage is where a throbbing headache will make itself present, you may feel nauseous or vomit, and you will likely be overly sensitive to light, sound, and sometimes other sensory stimuli. Without appropriate treatment, this phase can last for between four days and three days.
  4. Post-drome - this last stage differs for everyone, but it’s not uncommon to feel drained and confused after the “Attack” phase, however this stage may well not affect you.

How Does Stress Affect Migraines?

Although the exact causes of migraines remain unknown, many individuals report stress as triggering their frequent migraines. In a study of 1,750 migraine sufferers in 2007, 80% of participants reported stress to trigger their migraines, making it the most commonly recorded trigger[2].

Interestingly, most people tend not to experience a migraine at the point of increased stress (either physical or emotional) but rather once they’re able to relax after the stressful event. A 2014 study found that whilst increased stress levels didn’t lead to increased migraines occurrences, their perceived decline in stress levels the following day was in line with a spike in reported migraines[3].

This is due to a phenomenon known as the let-down effect. When encountering periods of acute stress, the body releases various hormones to prepare the body for fight or flight and bolster the immune system. A rise in cortisol, for example, helps protect against the perception of pain, that whilst being practical at the point of stress, can lead to a migraine being initiated once the cortisol levels reduce in the period following. Alongside migraines, this let-down effect from stress is associated with flare-ups of other chronic pain conditions such as arthritis and fibromyalgia, and reactivate viral infections like cold sores from the HSV-1 herpes virus.

Whilst there’s more research to be done in order to fully understand the causal relationship between stress and migraines, the promising early research gives food for thought.

How Do I Reduce Stress and Relieve Migraines?

Regardless of the causal link between stress and migraines, the correlation is undoubted, with painful migraines also resulting in greater stress which in turn can continue the cycle. Establishing healthy habits that support your mental and physical wellbeing will help reduce or even eliminate the daily hassles that contribute to acute stress.

How Do I Treat a Migraine?

Although having migraines is not a condition that has a known cure, appropriate treatment taken as soon as symptoms occur will significantly reduce the severity and duration of painful symptoms.
