The Moon’s Effect on Natural Childbirth


Moons effect on childbirthby David Rose


Do more women go into labor during a full moon? Would more women spontaneously deliver during a full moon if doctors and midwives did not remove babies early via C-section or labor induction?

Many experts will adamantly deny any evidence to suggest a relationship between the moon and our bodies. These experts seem to forget that just because something hasn't been proven, doesn't mean that it isn't real.

Did you know that some maternity units actually have more staff available during periods of full moon? I've always been fascinated by the moon's effect on nature, so when a friend's wife conveyed to me what her midwife had told her during the birth of their daughter, I decided to find out more about childbirth, full moon and a possible link.

On speaking to various medical staff involved in natural childbirth, the first thing I learned was that expectant mothers often experience false signs of labor during full moon. Contractions known as "Braxton Hicks" -- sometimes noticeable to the mother and sometimes not -- become more pronounced and many travel to the maternity unit in the belief that "it's time". Disappointed -- or perhaps relieved -- they return home, the pains having subsided with no dilation of the cervix.

While these expectant mothers visiting the clinic with their mistaken signs of labor are part of the reason why extra staff are needed, the major difference is found in the number of women whose amniotic sac -- the water -- breaks. Just as some women experience false labor pains, in cases where the water breaking marks the start of childbirth, full moon is the time when it's most likely to happen.

In order to discover for myself whether this could be true, I asked several female friends how their births had started. Those who responded with "the water breaking" were then asked the date of the birth. On checking this against a moon phase chart, I discovered that almost all had given birth on, or very close to, a full moon.

The theory is that the moon's gravitational pull effects the amniotic fluid in much the same way as it effects the water in the sea, rivers and even the water that's otherwise found in our bodies. "There are published works that show that there is such a relationship. One study looked at 5,927,978 French births occurring between the months of January 1968 and the 31st December 1974. Using spectral analysis, it was shown that there are two different rhythms in birth frequencies: --a weekly rhythm characterized by the lowest number of births on a Sunday and the largest number on a Tuesday and an annual rhythm with the maximum number of births in May and the minimum in September-October. A statistical analysis of the distribution of births in the lunar month shows that more are born between the last quarter and the new moon, and fewer are born in the first quarter of the moon. The differences between the distribution observed during the lunar month and the theoretical distribution are statistically significant." - Source: Full moon, Gravitational Pull and Childbirth,

As a woman's body prepares for natural childbirth, the amniotic sac becomes distended so the point where it will easily burst if put under pressure. Under normal circumstances, the pressure of labor contractions bursts the sac. During a full moon, the pressure caused by the moon's effect on the water inside the sac can cause the same things to happen, but without the accompanying contractions. When this happens, natural childbirth doesn't always move forward and with no other signs of labor present, the obstetrician may decide to induce the birth.

During my own study of this phenomenon I found that of 8 women whose births started with the water breaking at full moon, 5 of them had no accompanying contractions. A coincidence? Perhaps. But surely midwives wouldn't prepare themselves for an increase in natural childbirth activity if there wasn't some truth in this? One midwife told me that when it comes to planning childbirth, full moons should always be looked for around the time of the expected delivery. If there's one within a few days either side, the chances are your baby will be born on that day.

Sheryl's comment: Theoretically, many of our cycles should be naturally in sync with the cycles of the nature. In a world devoid of electric lights, women's menstrual cycles naturally synchronize with the phases of the moon in which they ovulate during the full moon and menstruate at the new moon (lunar fertility). There is more at play than simply gravitational pull. Total darkness signals your body to create melatonin and the sunlight of daybreak signals your body to stop this production. The light of the full moon is a signal for your body to cease melatonin production and that is what signals the start of ovulation. Electric lights are a huge potential factor in irregular ovulation.

hat said, we all know that hormones play a role in spontaneous labor and while I have no idea how the moon influences the hormones specifically related to childbirth, it stands to reason that nature affects our bodies a lot more than the medical community would like us to believe. To enhance the effects of moon, be sure to sleep in total 100% darkness. Even a small nightlight will throw off your melatonin levels. Make sure to get plenty of light during the day and open your blinds during the three days with the fullest moon. It may or may not help influence your birth but it will help your body connect with mother earth. Lastly, if you really want to let yourself connect with nature during childbirth then do not let unscrupulous doctors or midwives "get things going" by induction or any other methods. If you trust birth and allow your baby to come into this world when he or she is good and ready then you may just experience birth during the full moon.

    i’ve heard of this… i dont know about woman going into labor b/c of a full moon, but i know i used to work in a nursing home and my dad was a EMT and on full moons we were both crazy busy that day. my pt.s would not sleep and would wander the halls and he would be on calls ALL night. i’m not due around a full moon but i’m due in 3 weeks and there is a moon cycle change this sunday so we are keeping our fingers crossed and hoping!!! :)

  • Mira

    The forces of nature affect us in many ways that we are not even aware of. Nice example of this fact is shown in this article. How many of us ever co-related the full moon with child birth?

  • Cashmere Lashkari

    That is absolutely fascinating. Just imagine the child in the womb is affected by the same forces that make tides in the oceans.

  • Angela

    Our hospital recognizes that more people go into labour during the full moon and teased all the pregnant women on tours that if they wanted the best rooms for delivery to try to deliver a few days before or after the full moon.

    I mentioned this to a maternity nurse at another hospital and she looked at me like I had three heads.

  • jon

    “…, the average menstrual cycle is 28 days but varies from woman to woman and month to month, while the length of the lunar month is a consistent 29.53 days.* Some of us have noticed that these cycles are not identical. Furthermore, it would seem odd that natural selection would favor a method of reproduction for a species like ours that depended on the weather. Clouds are bound to be irregularly and frequently blocking moonlight, which would seem to hinder rather than enhance our species’ chance for survival.”

    i always thought it is a myth now i am starting to believe it.

  • Terry

    A friend of mine recently had these “false labor”. She ended up opting for C-section.

    This is truly fascinating as Cashmere pointed out. I would have something to share with that friend of mine when I see her today. LOL.

  • David

    Interesting information. I have heard a lot about the affects of the moon on living beings; mainly that the full moon can cause extremes such as crime. Haven’t heard about this though.

    Science does touch on this sort of thing with body rhythms. They will admit our bodies are in tune (somehow) with planetary motion, but they do not want to go out of the bounds of mainstream science with it.

    One of the things I heard that I found most interesting in this area is that when white people are put in sensory deprivation tanks that one of their body rhythms (I think it is Circadian) syncs with orbit of Mars, whereas black people’s rhythm will remain the same as earth’s orbit.

  • zev

    I don’t get how the moons gravity has a pole over earths gravity which is much much stronger

  • Stephanie

    Yeah its kind of niave to think that our womb is the only thing not effected by the ways of the earth. Somehow out of everything in the entire universe our uteri are the only thing impervious to the force. hahahaha. I studied in criminal justice and it is PROVEN that crime goes up during a full moon. coincidence? I think not. It is the shallow minded that can not comprehend things they do not understand. its more of a lack of putting two and two together on the nurses part who looked at the lady like she had 3 heads. We know. Im due around the time of a new moon though argh, I hop it may be of some use at least hahaha.

    my due date isnt until oct 2 but most people say that im not goin to make it that long.and my cervix is already opened.and we went to the hospital saturaday with bad contractions in my back and lower stomach…….and they gave me medicine to try to stop teh contractions…so do u think that i have a chance on having my baby on friday since thats our next full moon an dill be 36 weeks friday as welllll……

    yes it is true, its not only on child birth, but to us too, it is said that gravitational force of sun and moon gradually effects to nerve system of human body, such natural phenomena may be good or bad, it may be good for those whose vital force is high and bad for some whose low.

  • Mike

    Reading your posts on these natural issues are like listening to my grandparents. Thanks for sharing these info and letting the world know about it. – Mike

  • cheri

    The Moon’s gravitational pull does not counteract that of the Earth’s, rather it acts in addition to it. It is most evident with all things watery as this type of matter flows and so shifts and movements are obvious.
    Seems like common sense to me that it would also affect our own bodies’ rythyms as (I think) it’s 75% water. I don’t know why Science is so scared to accept this!

  • Natural Childbirth

    Perhaps women’s cycle’s wouldn’t vary wildly if they weren’t exposed to constant nightime artificial light.

    In addition, do you find it odd that sleep itself (for all species, not just a species like ours) would be dependent on the weather or do you feel that melatonin pills created in a lab make more sense for living beings than darkness?

  • David

    No it is absolutely true, only reason is our body is comprised of 90% of water and moon’s gravitational force effect on us just as it effects on oceans and mountains, and hence it has a lots of effect in our body too

  • Dave Sappers
    Dave Sappers

    This is so true and exciting too. I m sure many of us won’t know this facts, infact our own moon has an impact on our own body too and reason is that about 70% of body is made up of water and hence moon’s gravitational force act more on water.

    its totally weired to believe that gravitational pull of the moon and sun had to something with the birth of a child .its crazy .well i must say women out there who all are expecting child should set their calenders right .

    I know that moon has an effect in nature but i never thought the the moon has an effect in getting birth.

  • Mike

    Amazing! i am surprised and quiet intrigued by the effect of moon on our body,well when i was a kid i learned that the gravitational force of the moon keep us footed on the earth and they do effect our mind body and soul in certain way.But it effects a pregnant lady in such a way is really a fascinating thing to know. @Holly all the best for your delivery :-)

    Well I have two personal experiences to add to this debate.

    1. While living on a tiny island in the Pacific for a couple of years which had no electricity, my body definitely aligned with the moon cycles as did my cycle. In fact, on the island where I lived a woman’s time of the month was known as “crashing with the moon”. And Jon, even if there were clouds in the sky, the moon impacted tides and my cycle.

    2. I am currently pregnant, 3 weeks away from my delivery date but have gone from having 5-8 Braxton Hicks contractions to 20+ just within the last 24 hours. Today is a full moon.

    I’ve done no widespread research, and I am just one case, but my personal experiends leads me to believe that there might just be something to the moon impacting body cycles.

    Hi I have a quick question. Why does it seem doctor's and hospitals are against Natural childbirth?

  • dhivakar

    please tell me the effects of child birth on the full moon Day i.e on 30/oct/2009

  • Julie

    The full moon had an effect on both of my pregnancies so far. With my first, I went into labor on the night of a full moon. I was at 36 weeks and my water broke without any contractions. I am currently at almost 34 weeks and at 32 weeks I went into false labor, which happened to be a full moon that night. I heard that the next full moon is May 27th, 2010…I will be almost 35 weeks then. I think that will be the day.

  • Kharma

    This is fascinating. I’ve long heard of the correlation between childbirth and the full moon, but I never understood WHY this might be, until this article. Thank you for explaining it so well!

  • Jessica

    With my first child I went into labor on the day of a full moon, when I walked into the L&D unit a nurse said “here comes another one!”, I guess they were running out of rooms! My second child was born a couple days after a full moon, and now my third to be has a similar expected due date as my first one due a couple days after a full moon, we’ll see what happens, but I truly believe this theory.

    I have not seen any dissenting views. The fact is, this is sheer lunacy. The moon’s gravitational pull on the “water in your body” is less than the effect of another person’s body standing next to you. This argument is old and has been discredited time and time again. Please don’t believe everything you read (even this) without making a valid attempt to determine the truth.

    My water broke 1 day before full moon and I gave birth on the day of the full moon, which was also the due date. No contractions, so I was induced.

    Now I am pregnant with my second, and the due date is 1 day before full moon! Makes me wonder.

  • Rhya

    I believe that a full moon caused by water to break. My due date by Feb. 14, 2009. On Feb. 6th, I was only dialated to 1 CM. On Feb. 8th at 3 a.m., by water broke. It was a full moon. When I arrived to Labor & Delivery, I was on 1.5 CM. They gave me potocin to progress my labor & that did not work. They had to insert a pill into my cervix and give me more potocin on top of that to make my labor progress. On Feb. 8, 2009 at 5:29 p.m. my son was born. I truely believe the full moon did cause my water to break.

    I don’t think that the moon phases affecting a woman’s biological functions is far-fetched. Just for kicks, I checked a farmer’s almanac for my birth in 1968 and my son’s birth in 2004. Both of us were born, without inducement on full moons. Maybe it’s a coincidence, but it is definitely interesting.

  • CeeCee

    I am SO curious to see if I go into labor tomorrow! Tomorrow is Fri. Aug. 15th 2011. It is a full moon and I am 38 weeks along. I have been having bad fake contractions for a week now, so I am HOPING my lil girl will make her debut! In fact, I just packed my bags “just in case!”

  • Geoffrey

    The “experts” that would adamantly deny this would probably have got along well with the scientists who once thought the world was flat and that you would fall off if you sailed to the end of it ;)

  • Annie

    My water broke on my due date which also happened to be a full moon. I waited several hours to see whether contractions would start on their own and when they didn’t, headed to the hospital where I had to be induced. Upon examining me, the doctor’s said she was nowhere near ready to come out on her own. I was only dilated to 1 cm (barely) and 50% effaced. I fully believe the full moon had something to do with this. I am 8 days overdue with my 2nd and there is a full moon in 2 days. We’ll see if I go 2 for 2.

    “Unscrupulous midwives inducing labor”??? Come on! I think you need to do more research and become better acquainted with what midwives are all about and what kind of care they provide.

  • miranda

    I’ve read and heard from my friends in the field that hospitals in general tend to have more people on staff during a full moon. Part is due to pregnancies and part if due to more accidents so emergency rooms are also staffed with more people.

    My wife’s waters broke on a full moon but we just considered it to be a coincidence. Interesting to read the above article.

  • Trev

    I’m in week 30 of my pregnancy and the more I read about stuff the more freaked out I become. I have definitely noticed some changes when there is a full moon, i’m going to start keeping a journal now. This is my first child, the journal should help with my 2nd and 3rd (If there is going to be one).
