7 Ways The Full Moon May Affect Your Health

Turns out, a full Moon can affect our physical well being in many ways. See what researchers discovered...

We’ve got a full Moon coming up! We often hear from our readers that the world goes a little off-kilter during this time—kids act up, people are more impatient, car accidents, and more. Even the word “lunatic” stems from the Latin word luna, meaning Moon, and there’s plenty of evidence to support that erratic behavior does occur in some people around the time of a full Moon. But can a full Moon also affect your physical well-being as well? We checked in with some experts on the topic.

7 Ways The Full Moon May Affect Your Health

Here are some interesting things researchers have found regarding the full Moon and its effects on your health.

1. Heart

Can the Moon’s cycles have an effect on your heart? Apparently so, but not in the romantic sense. A study published in the Indian Journal of Basic and Applied Medical Research found that when exercising, your heart is at its peak performance during a full and new Moon. So check the phases of the Moon before hitting the gym!

2. Brain

Much like the Moon is responsible for the ebb and flow of tides, because our brains are a significant source of water, Dutch researchers hypothesize the Moon’s gravitational pull could similarly have an effect on your brain, causing erratic behavior. Read: Do Full Moons Make People Crazy?

Other studies by British scientists reveal that a full Moon may actually decrease seizure activity in epileptics. In these cases, however, researchers suggest it may be due to the brightness of the Moon rather than its phases. When the Moon was bright, participants had fewer epileptic seizures. They attribute this to the hormone melatonin, which is naturally secreted in your brain when the Sun goes down, hence signaling it’s time to sleep. In epileptics, they surmise, the brightness of the full Moon counters this release, thus decreasing seizures.

We also hear from our Facebook fans all the time: complaints of headaches and migraines around the time of the full Moon. While no scientific correlation is made between migraines and the full Moon, full Moons can disrupt sleep (see #4) which, in turn, disrupts hormone levels, thus triggering headaches.

3. Kidneys

A 2011 study published in the Journal of Urology found that kidney stone pain increased significantly during a full Moon. And in another study, English researches found that generally, more patients were admitted to hospitals with urological emergencies during this time, too. Conversely, the new Moon caused a “calming effect” for people with these conditions.

Coincidence? Maybe not. One theory behind these conclusions is that the kidneys, like other organs and the human body itself, are made up of about 60 percent water, and just as lunar activity can affect our oceans, creating powerful and predictable tides, the Moon may affect the workings of these organs, causing a noticeable ebb and flow in times of calm and pain. Not all researchers agree, but there is enough evidence that additional studies are in the works.

4. Sleep

Calm and peaceful woman sleeping in bed in dark bedroom. Lady asleep at home in the middle of the night. Pillow, blanket and moonlight.

A 2013 study published in Current Biology reviewed the sleep patterns of participants over three days in which they were allowed to fall asleep at will in a controlled area that had neither clocks nor outside light. When the data was compared to the phases of the Moon, researchers determined participants not only had lower melatonin levels during bright Moon phases, but they also took 5 minutes longer to fall asleep, slept 20 minutes less in general, and had 30 percent less REM sleep. And if you’re not getting enough sleep, your health suffers. Try these tricks to get a good night’s sleep!

5. Menstrual Cycle

A woman’s average menstrual cycle is 28 days, which is quite similar to the 29+ day lunar cycle. This timing may be more than coincidence according to Chinese researchers who discovered that almost 30 percent of all the women monitored ovulated at the full Moon and menstruated during the new Moon. In some cultures, there is even a name for this phenomenon, called White Moon Cycle, which essentially mirrors the fertility of the Earth which is said to be most fertile under full moonlight.

6. Birthrate

Japanese researchers discovered something interesting: there was a significant increase in the number of births when the gravitation of the Moon to the Earth was most powerful. While researchers admit they are still unclear on exactly how or why this relationship exists, they say it might help healthcare professionals and pregnant women better prepare.

Additionally, one Italian study examined more than 1,200 births over three years and found a higher number of babies born in the two days after a full Moon.

7. Injuries

Since the full Moon can affect our behavior in certain ways, it should come as no surprise that we are more prone to accidents or illness during this time, according to some. One 2011 study published in World Journal of Surgery found that over 40 percent of medical personnel believe in “Full Moon Madness” among patients. It was also revealed that emergency calls for all sorts of conditions actually increases by 3 percent whenever there’s a full Moon, and then drops by 6 percent during a new Moon.

In 2008 British researchers found a link between the lunar cycle and what doctors call “medically unexplained stroke symptoms,” where patients develop complaints such as headaches, numbness and coordination issues but have nothing physically wrong with them.

Darlene Rousseau

The wolf moon of January 2022 affected me by pain in my left leg that has steel, and my head ached all night. This also occured with the Blood Moon in November 2021.


I was physically assaulted in 2019 . Were I ended up having serious back pain. I lost my period since that day. Later on I started to have breathing problems where I mostly use Nebulizer to breath . Mostly when there’s a full moon I suffer a lot . More back pain , can’t breath at all I can’t sleep . What should I do ?


Please I would like to get an answer . It’s very important. Can the moon affect my health. I look forward to an answer. Thanks.

Yvonne Young

I don’t have the answers you are looking for but I can tell you that I too have difficulty breathing and very agitated during the full moon and it lasts for about a week. When I know a full moon is on the horizon I have to tell myself and remind myself that this is only a once a month thing and sometimes I am able to calm myself. You are not alone!!

Bess Coleman

Having worked with a midwife for many years l noticed that a majority of labours began when the noon was in its what l call peanut phase, it is a peanut shape, a few days into waning after a full moon.


I definitely sleep less and feel more energetic.

Amanda H

I had the worst panic attack of my life Wed & it’s effects lasted for days. I fully believe it had something to do with this full moon. My heart was also acting very strangely, as though I was having a heart attack! So happy this full moon is over. LoL

Mona Nasrallah

Migraine correlation to full moon 🌕

I am trying to figure out what causes my migraines as I’m otherwise completely healthy. Does anyone else think this as well?

Colleen S Thompson

hormone fluctuations…it happens to me that way


Yes I get a migraine when there is a full moon and emotionally flat as a pancake

Nicki Norwich UK

Amazing reading, totally fascinating
I am regularly affected by the moon, and this current Beaver Moon (November 2021), I have felt way more energised than normal, and super confident in my day to day tasks, like I could rule the world!
I sleep well, but wake early.
I am an Aquarius (if anyone finds that relevant).

Mona Nasrallah

For me it’s opposite as I think my migraines correlate with full moons so consider yourself lucky if anything matters I’m a cancer born June 27th.

Nancy S Blake

The veterinarian I worked for would not castrate horses, bulls, or dogs on a full moon…he said they would bleed heavier than normal then. Most of our cows had their calves during full moon or the day after.


As a Nursing Home Administrator in a Mild Mental Facility, We notice a huge difference of increased aggression/agitation in patients during a full moon.

Colleen S Thompson

jail riots, escapes also…they call it “parole dust”


I can believe that! I feel agitated/a bit depressed and overall unwell.Headaches/ migraine.


I am already feeling the effects of the full moon 10/20. Fatigue, brain fog, no appetite. So glad to see I’m not losing my mind. I’m finding myself more moon sensitive as I age. This is something else.

I read somewhere that the full moon pushes the troposphere down which increases the level of poitive ions in the atmosphere. The full moon increases positive ion ratios, which accounts for the strange and aggressive behavior noted by police and medical services. Studies show that 75% of the population is noticeably and adversely affected by positive ion ratios, while increased negative ions tend to have a calming influence on these same people. The effects of alcohol are increased. In some Europeon countries the do no perform surgery during full moon unless the have negative Ion generaters in the hospital. Negative Ions from waterfalls effect some with a calming euforic feeling


Thank you for that information 👍


Is anyone here affected by the balsamic /new moon? My cfs/fibromyalgia/emotions flare a lot!


Yes I was hoping someone else could tell and I wasn’t crazy!! I have Lyme Disease and the moon effects me big time! Today I just don’t feel good and I dizzy.


Ive been extra dizzy too and the barometric pressure is super high! New moon in a few hours EST 🌑


Yes me too.Dizzy and headaches.


It’s a full moon today September 20 and I just can’t sleep even though I’m yawning nonstop and this partial right side headache won’t go away but I know I’ll be like new once the full moon is over.

Toni starbuck

I too have similar issues, my hands go numb, I’m very tired throughout this time as well as intuitive. Often of balance and yes quick to anger.

I always find the information shared in your feature stories about natural phenomena fascinating. The articles on the Harvest Moon and how the moon affects your health were no exceptions. Thank you ☮️

Mike Ohlinger

Yes the full moon affects stability in my health usually 2 days before n after a full moon. Thanks for asking n good data.


I always get I’ll leading up to the full moon,irregular heart beats,bloating and feeling strange and disoriented,it’s terrifying,I dread it every full and new moon

Lila Cothran Campbell

I’m sorry you get this but happy to have found some company in this ;-/! Are you a Cancer by any chance? Has this been going on long time for you?


I’m a cancer and it happens to me every single full moon but different some full moons are headache numbness some are full of energy wanting to go out and do everything but not today September 20.2021 I feel like dying


Days before a full moon I’ve noticed my panic attacks and anxiety are insane. Dizzy feel ill. Does anybody else get this way days before ??! And how do you cope ? TIA


Yes, me to,it’s awful,and it’s twice a month

Lila Cothran Campbell

YES! Not anxiety as much as physical symptoms – weak, irregular heartbeat, disoriented, dizzy, headaches, sore throat, slight fever – with full moon and sometimes with new moon. Sooooo over it. No doctor believes it so far. Just tonight had to cancel plans to go to a fun party.


This is exactly how I feel. I thought I had COVID. Went to ER. All bliss work, ekg, urine sample, chest exams came back good. They said it was attributed to vertigo because I experience dizziness, like disoriented, left side heavy, I’m confused and everything feels heavy. My ears are constantly popping and just feel weird in the head. Is this common and what have been the go to’s during this time. Will this go away!

Susan Higgins

Lindsay, try switching to a low-inflammation diet. Sometimes if we’re eating foods that cause inflammation, our bodies “rebel.” There are several good programs to follow. Hopefully, you’ll start feeling better soon!

Debbie Atherton

Yes me to so please to find this


I almost hate the full moons they affect my mood so much sometimes it is hard to function. Is there a way to deal with this?


I hate full moons. They depress me. Also very irritated and feel down all the time until the full moon passes. I went to an astrologer one time, she told me because I have so much Capricorn in me I will be affected always. Any suggestions?


Definitely I’m not right when it’s full moon, memory loss, fatigue, guilt for not being on the ball, and menastual cycle and when it’s at its peak, wake up at 3/4 am and not getting back to sleep.

Moe Martinez-Mortera

My sister and I woke up with our feet, and hands swollen! I had a headache on my left side like something was being pulled. Also a pain in my left leg, at times tingling like my foot had felt a sleep! Is this something someone else has experienced?



Emily Fenech

I will be awake for hours around the time of the full moon even though I have increased the medication which helps me to sleep. Also I have rashes and around the time of the full moon these become intense and really prevent me from sleeping.

Tannis Clark

My adrenaline goes crazy with full moon very aggitated

Joyce Benedict

If anyone has had pets their activity at new and full moon is legendary. Dogs, cats, have all disappeared or been wounded at these times. I lay awake for hours at full moon time. New moon is no picnic either for health issues to be more annoying. Foods eaten at restaurants do not taste the same for me. I never eat out at those times. Both full grown sons confirm after years noticing as I have. There are magnetic fields that are altered. Our body, foods made up of cells, energy, etc.
As an Astrologer who has observed human behavior for over 45 years, no doubt in my mind “there is a time for everything”.
I believe the lunar cycle plays a role in producing an extra egg based on position of degrees in a woman’s natal chart between her sun and moon. If 144 degrees in her pattern then each month that moon/sun in the heavens reaches 144 degrees and an extra egg is released. This accounts for many pregnancies supposed to not occur. When accurately calculated, that time frame of 3 days can be used as a time to conceive if wanted, or an avoidance of sex. Accounts why many women have conceived night before period or during period.This system studied by Egyptians, a German Gynecologist studied it with her patients, I used myself and for clients.
We are ‘children of the Universe’ and the more people study cosmic cycles they would better understand many facets of their behavior.
A successful dinner party? Moon in fire or air. Bought an item of clothing you regretted days later? You succumbed to the powerful energy of a moon in a sign contrary to your own energy field? Were the ancient gardeners wrong about what to plant when? No. Stands to reason we as humans need to learn about cosmic cycles to cooperate with them. Some of the worst wars, assassinations, violent outbreaks occur with planets in Aries. There were 4 in Aries at one point recently. Remember shootings after shootings, after shooting? Happily married but magnetically drawn to another and ‘almost’ gave in or did? Venus or Mars activating departments associated with sex, hidden activities. There is a better time to conceive to avoid complications or birth defects.
“For everything there is a season, and a time for every purpose under the sun.” Ecclesiastes 3:1-15.


Your comments were so interesting. Going to further look into it.


Hi I am Mumtaj fm India. I have migraine last 20 or more years. But I have experience that migraine pain more powerful on full moon or new moon cyclic time.

omg Same.. Its killing me for 2 days now


Intestinal parasites are most active during the full moon when melatonin is low and seratonin is high. There is a lot of information on line about this that some people with unexplained physical and mental symptoms may want to investigate. Doing a parasite cleanse during these times may relieve symptoms.


Oh yes! Thank you for poiting this out. Most of the complains people is attributing to the moon alone is due to the active phase of the parasites…the sleep and anxiety are just a couple of them. So the cleanse could be what eradicate the symptoms. But it must be done a few times cause these little creatures left the eggs and the cycle will start again.

Mr. S. from MA

Omg, must be true. My injury occured on a full moon day. Happened long ago & I still remembered the date. I looked it up.

janine mckee

Hi I have arthritis and fibromyalgia among other illnesses and just before the full moon every single month my pain increases I get headaches I wee a lot more and I cannot sleep im more tired irritable and sensitive during this time I kept a diary for a yr it was the same every single month I run a fibromyalgia group and I’m not the only person This happens too xx

Lynn Campbell

Thanks for sharing this info in relation to fibromyalgia. I notice that my fibro flares around full and new moon it also makes my anxiety levels go through the roof. It’s a relief to see I’m not going mad and others suffer similar issues too


I got osteoarthritis,and a few days before full or new moon it gets much worse,anything wrong in the body gets much worse at full moon,the moon emphasizes it,I try to relax and use lavender oil to inhale and drops of (rescue remedy drops) these help a bit


Any chance of getting a link to your fibromyalgia group? I have had it since 1997. But have learn what helps me deal with it.


The pain thing happens to me too. My jaw starts tightening, teeth have that weird shivery sensation (especially the lower jaw). My head hurts and I have a full body pain, despite there being no existing medical conditions or bone disease.

This has been happening to me since birth. I have experienced pain since as long as I can remember. And it becomes worse at night.

Family went to a doctor when I was a child and the doctor said that since I was getting too tall too fast for my age, I was experiencing growth pains.

I am almost 27 years now and still haven’t stopped getting these growth pains. I am still unable to sleep at night due to being in pain.

I know that this overwhelming growth pain happens during full moon, but this has become such a common occurrence for me that I have stopped keeping tabs on the lunar calendar. My body tells me when it’s time for the coming of the full moon.

As for erratic behaviours and strains in family conditions, I wouldn’t know. I have started living away from my family as soon as I turned 18 so that they don’t have to witness me going through this every month. I don’t like being pitied.

Pain killers do help dull the pain but I now have to take larger doses as my body has started to build immunity to pain killers. Also, if I take too large a dose then the medicine simply knocks me out and I am then unable to work at all. Alcohol does not help. AT. ALL. It just worsens everything as it gives the worst of hangovers. So basically, if I have to work during full moons, then I simply endure the pain. Also, if I am lying down, I’ve found that not moving and not clenching any muscles makes enduring the pain easier. Tightening your muscles will only make it worse. I can’t even smile or raise my eyebrows at times as that causes my face muscles to start paining and that just adds to my existing headache.

Also, since the pain becomes worse at night, I have taken to sleep during the day. Eventually, I have realised that working during nights is easier than day as I feel drowsy during daytime.

Also, I feel somehow this has shaped my body structure in some ways as I do have a high metabolism and I don’t accumulate fat even though I don’t do any kind of excercise (Think in terms of a couch potato). And this is helpful for me because I tend to eat a lot as I get hungry very fast.

Hope this helps any “Moon-peoples” who are looking for help.

We share the same fate during the full moon. The least I can do is stand by them.

I do understand where people get the legends about “people who turn into something else during full moons”. Funnily though, I’ve never turned into a wolf!

S.J. What you describe sounds like seizures. Perhaps contact your doctor today and see what’s really going on.


May be seizures, but there is help.. my wife had (has, but we don’t claim them) 3 types of seizures.. this might be Catamenial epilepsy (CE), also known as menstrual seizures, is linked to a woman’s menstrual cycle and related hormone levels in the body. Women with CE often have more seizures during certain times of their cycle. By God’s Grace, eating healthy, washing foods, and staying away from plastic amongst other things..
Most importantly, JESUS SAVES! Praying For You S.J. If He brought you to it, He’ll bring you through it.

Susan Higgins

Hi Ganeasan.s please visit your doctor. We don’t provide medical advice. Good luck!


This is and old thread but if read, it could probably be parasites. They are more active at this time and those could be some of the symptoms.

It gives me really bad gas back pain


For me when the moon is waning crescent or waxing crescent everything is in chaos and strange energy. I am clumsy, hyper, easily aggravated, and things seem to just fly out of my hands, etc. I do not look forward to moon cycle under crescent moon and I have found NOTHING at all anywhere to explain why this phase is so intense for me.


Hey Marie, I work alot with the moon phases on a spiritual healing level. I have being doing this for over two years however I have been doing shadow work and self-work for nearly 10 years. Basically self-improvement through looking at what makes me unhappy, letting go of the past and being aware that I create my reality through my thoughts and feelings. I have also noticed the same thing as you but with the new and full moon phases and in my experience you won’t find anything that can explain to you exactly why it happens that way to you. I can try and help you though. The waning crescent is when the moon is getting smaller towards new moon so maybe it’s asking you to look for new ways of doing certain things in your life. As for the waxing crescent, that is heading towards full moon so it may be asking you to release old ways. Do you see the link there? The moon is associated with our emotions and subsconscious and the phases of the moon shine a light on what we need to work on within ourselves and that is why you won’t find anything about this becasue it is so unique to each person. My advice is to journal your thoughts and feelings and notice when you are triggered. The more you tune into this energy, the more self-aware you become of your actual thought patterns at this time and what exactly is going through your head and you will know instinctually what you need to do in a new way and what needs to be released from your life. Also remember that it is not only things outside of us that we need to work on, we also become aware of our own negative repetitive thought patterns and their root cause; eg family karma, trauma, outdated beliefs, unhealthy habits and behaviours, you get my drift! When we try and avoid these things we get triggered more easily. That is why I love the moon, it helps me to work on whatever is coming up at that time. It is impossible to work on everything at the same time, its a journey not a race so just take one day at a time and you will be just fine. 🙂


During the full moon I get very crabby ridiculous things happen to me a lot to irritate me during the full moon, such as going out and getting cold food instead of it arriving at our restaurant table hot, hubby will drive unsafely a s I get upset. The full moon seems to bring me bad luck. It has never failed
