Full Moons and Migraines

The impact of the full moon on migraines, while not properly or thoroughly researched, is one that is generally accepted within the patient community. I have certainly noticed that the full moon brings an increase in severity of my migraines and have heard from others who share the experience.

There may be several reasons for why full moons result in a rise in migraine activity.

Hormonal shifts

Women’s menstrual patterns can cycle with the full moon (similar in length to the lunar phase) leading to a potential double whammy of hormonal shifts along with whatever impact comes along with the full moon itself. Hormonal shifts are a well-known trigger for many women who struggle with migraines.

Sleep challenges

Studies show that the full moon can alter sleep patterns. This can make it more difficult to both fall into and maintain a full night sleep. As we all know, disruption in sleep is a well-known trigger for migraines.

Psycho/social/emotional disruption

The full moon has an impact on serotonin levels, a chemical in our bodies that regulates mood, among other things. Its imbalance could be the cause for the wide ranging reports from emergency rooms during full moons regarding the increase of incidences involving migraines, alcoholism, epilepsy, menstrual cycles, car accidents, anxiety, depression, sexual activity, homicides, insomnia and diarrhea.

High and low tide

With 70-80% of the human body being composed of water, it has also been proposed that if the gravitational force of the moon is sufficient enough to cause the oceans to rise, it may also affect our bodies.

With migraine triggers lurking around every corner, it can be tricky to keep track of them all. That said, the full moon is one trigger that we can anticipate. Proactively taking the full moon calendar into account might help us avoid migraine, or at least decrease its severity and/or frequency. For example, if you believe the full moon is a trigger for you, you might talk with your doctor about the idea of proactively ramping up your preventative treatment strategy in anticipation of the date. Additionally, you might use the calendar when planning in advance for a trip or other special event in an effort to decrease the likelihood of having a migraine.

For your convenience, here are the upcoming full moon dates for the near future:

    Please be aware for most of us that the full moon does cause migraines. The “new moon” is just as bad if not worse. Please check that out for yourself you will probably find the same thing..

    Hi @david901– Really glad you shared this information. I’ll definitely look into this and pay attention. I also notice that some full moons cause much more intense pain than others. No idea why this is the case. Grateful for your input and your presence in our community. Please stay in touch.

    Hi Holly! I love the fact that we both wrote articles about this at the same time. I have edited mine to mention yours and link to it. Yours is more scientifically based and mine is more poetic, which I think is cool 🙂 Here is the link to my post which was published yesterday.

    Great migraine minds!

    Hi Elizabeth!

    This is a wonderful coincidence! When I was first considering the content of this piece, I searched the site and saw there was not much on the subject. I agree that it’s very cool that we both chose the explore it in depth at the same time. I loved your piece and thanks for linking back to mine. Very warmly- Holly

    Those times are not going to be correct for all time zones, as that the full moon doesn’t crest in every time zone. I believe the Farmer’s Almanac asks for your zip code when you access their site, to give you the most accurate info for you.

    I’ve always been sceptical about attributing anything to the full moon. The thing is, it’s always there, it’s just that for a few days every month it’s very visibly there. It passes overhead at some point every day.

    We have high tides twice a day, once when the moon is overhead and once when it is on the far side of the world. So if there is a link between migraine, sleep and tides it would also be apparent at new moon, when high tides also coincide with sleep.

    The visibility of the moon, and it’s intense light when reflecting the sun ‘full on’ could well be a trigger. It adds to ambient light even on cloudy nights.

    Of course my scepticism isn’t a reason not to monitor my migraines against lunar activity, it’s just that I have them all month round – usually one a week. I think I may take the time to go over my diary for the last few months and check intensity at different moon phases.

    Hmmmmm I might have to track this …… full moon last night and bad migraine last night as well.

    I do remember quite a few nights having severe pain and unable to sleep so I sit at the window watching the moon and it’s normally full or almost.

    Would suck to have another unavoidable trigger but I could at least plan around it easier than pressure changes in the weather.

    Hi Tamara- Thanks for sharing. Yes- the timing of this article release is perfect as the full moon was last night. Great idea to begin paying attention to see if it might hold some connections for you. And you’re right- perhaps there may be some ways to treat yourself preventively around those times if it is an additional trigger for you. Best of luck! Warmly – Holly Baddour (moderator/patient advocate-
