Full Moon And Period At The Same Time Does The Moon Influence Our Menstruation

The full moon is one of the most important nights of the month for women, as it is when their menstrual cycle begins. In some cases, the full moon can even trigger menstruation. While there is no one answer to whether or not the moon influences our period, there is evidence to suggest that it does. For example, studies have found that women who have their period at the same time as the full moon are more likely to have heavier periods. Additionally, some women report that they have had more intense or painful periods when the full moon is present. While there is no definite answer as to why this is the case, it is possible that the moon’s gravitational pull can affect our hormones and menstrual cycle in a variety of ways. Overall, it seems that the moon does have an effect on our menstrual cycle, and it is something that women should pay attention to.

It happens that the period and the full moon fall on the same day. Could there be a connection between the lunar and menstrual cycles – or is it just a myth?

Full moon and period: what influence does the moon have?


The moon has a significant impact on our menstrual cycle. The full moon typically occurs around the time of ovulation, which can lead to increased fertility. Additionally, the light of the moon can suppress the production of the female hormone estrogen, which can help to regulate menstrual cycles.

There are many arguments that could appear to suggest that there is a connection between the phases of the moon and menstruation. The question is not only discussed in various cultures and mythologies (the terms “menstruation” and “menses” derive from the Latin and Greek words for month (mensis) and moon (mene)), but also hotly debated on online spiritual blogs. Even many major scientific journals have already devoted themselves to the phenomenon that certain phases of the moon (especially new moon or full moon) occasionally coincide with the period. So this question doesn’t seem to be entirely out of thin air. After all, there are also many observations that could support this assumption, at least at first glance:

  • The average menstrual cycle has 29 days, the lunar cycle has 29.5 days – chronologically about the same length.
  • The moon also influences the ebb and flow. Our bodies are also mostly made of water, so why shouldn’t the moon affect that too?
  • Older studies have shown that women whose menstrual cycles are in sync with the lunar cycle are the most likely to become pregnant, so there seems to be at least a fertility link.
  • It is known that certain animal species have also synchronized their reproductive behavior with the lunar cycle in order to improve reproductive success.

The moon and menstruation: that’s what studies say

There is a lot of scientific data that suggests the moon has a significant impact on menstruation. For example, studies have shown that the lunar cycle can affect the length, severity, and flow of menstrual periods. Additionally, the location of the moon during a woman’s menstrual cycle can also affect the flow.

Some scientists believe that the moon’s gravitational pull can affect the hormones that women produce during menstruation. This may cause some women to experience heavier or lighter periods, or longer or shorter periods. And, of course, the timing of a woman’s menstrual cycle can also be affected by the moon.

Overall, it seems that the moon has a lot of influence on menstruation. However, more research is needed to confirm these findings. In the meantime, women can take advantage of lunar cycles to help them better understand their own menstrual cycles.

However, only a look at scientific studies and investigations that have researched the connection between lunar and menstrual cycles provides information. And there are quite a few: At the beginning of the year, a study by the University of Würzburg, which was carried out by a team led by zoologist and neurobiologist Charlotte Helfrich-Förster, attracted attention and the results of which were published in the online knowledge magazine “”. The study was based on data from 22 women who tracked their menstrual bleeding over periods of up to 32 years. What was found: That the onset of menstrual bleeding actually took place synchronously with certain phases of the moon (full moon or new moon). However, this synchronicity only applied if the menstrual cycle lasted longer than 27 days. Another study with 312 subjects from 1979 claims to have observed such a correlation with a corresponding cycle length. But: On average, this synchronicity among women under the age of 35 was only a quarter of the recorded time. For women over the age of 35, it was only about a tenth of the time.

How do moonlight and gravity affect periods?

Periods are a very important part of women’s lives. They are a time when women can talk to their friends, do their hair, and most importantly, have their periods. There are many myths about periods. One of them is that periods are caused by the moon. This is not true. Periods are actually caused by the hormones that women produce. The moon has nothing to do with it. However, the gravitational force of the moon does affect how long periods last. The greater the gravitational force, the shorter the period will be. This is because the blood flow slows down when the gravitational force is high.

The research team led by Helfrich-Förster attributed the observed connections between the moon and menstruation to the influence of the gravitational force of the moon, but also to moonlight. Synchronicity seemed to drop when the women were exposed to artificial light sources at night. Even in night owls, who only switch off the light at a late hour, it was no longer possible to observe the synchronization of menstruation and the moon. Other studies have already shown that people who work night shifts, for example, tend to have irregular menstrual cycles. Helfrich-Förster and her research team suspect that in ancient times women still had a complete synchronicity of the cycle with the phases of the moon – but modern lifestyles and artificially generated light have thrown this temporal coincidence out of rhythm.

Even if the moonlight is largely responsible for the synchronicity, the gravity of the moon is said to have an effect on the menstrual period. According to the study, a connection between the moon and menstruation could be observed particularly often in those years when the sun, moon and earth were always in roughly the same line when the moon was closest to the earth (and therefore the force of gravity was highest). was. This occurred exactly in the years 1961, 1979, 1997, and 2015, i.e. always in 18-year cycles – a rhythm in which the three lunar cycles combine to form very special constellations. Incidentally, all three lunar cycles have an influence on the intensity of the moonlight and gravity.

The three lunar cycles at a glance:

Which speaks against the connection between the moon and menstruation

The moon has no connection to menstruation. This myth is based on a misunderstanding of how the moon orbits Earth. The moon does not have a gravitational pull on Earth, so it does not cause menstrual bleeding. The moon is also too far away from Earth to have any significant effect on our planet’s weather or climate.

The problem with the meaningfulness of the study by the University of Würzburg is that data from only 22 women were evaluated – a very small number of test subjects. However, the data science team of the period tracking app “” also got to the bottom of the question and evaluated the cycles of a total of 7.5 million users who did not use any form of hormonal contraceptives. The study is thus the most extensive that has ever been carried out on the issue. However, the results speak less for a correlation of certain lunar cycles and the period. Instead, it was analyzed that the onset of menstruation was randomly distributed throughout the month, i.e. independent of the phase of the moon. The team around Dr. Marija Vlajic Wheeler also points out that while the average menstrual cycle is around 29 days, most menstruators typically have a cycle length of between 24 and 38 days. The synodic lunar cycle, on the other hand, is about 29.5 days long. From a purely statistical point of view, it is therefore unlikely that the period at new or full moon begins more frequently than at other phases of the moon.

Even if it is not scientifically proven that there is a correlation between the lunar and menstrual cycles, many menstruators still find that the different phases of the moon can be important for their own period or in other areas of life. So some people even adjust their .

”What does it mean when your period syncs with the full moon?”

A few days before a woman’s period begins, production of the hormone progesterone ceases, and low levels of this hormone trigger menstrual bleeding. She says that for a woman’s menses onset to sync with the full moon, the progesterone-producing structure would need to receive a signal in advance of the full moon.

When your period syncs with the full moon, it means you are fertile and are likely to conceive. The full moon also increases estrogen levels, which can help promote ovulation.

Does moon affect menstrual cycle?

Menstrual cycles also aligned with the tropical month (the 27.32 days it takes the moon to pass twice through the same point in its orbit) 13.1% of the time in women 35 years and younger and 17.7% of the time in women over 35, suggesting that menstruation is also affected by shifts in the moon’s gravitational pull.

The moon has been known to affect women’s menstrual cycles since ancient times. Some people believe that the moon affects our menstrual cycles because it impacts the hormones that regulate fertility. Other people believe that the moon affects our menstrual cycles because it affects the way our brains produce hormones. Still others believe that the moon affects our menstrual cycles because it impacts our circadian rhythms. There is still much unknown about the moon’s impact on our menstrual cycles. However, there is evidence to suggest that the moon does play a role in our menstrual cycles.

How does a full moon affect females?

A 2015 study of 205 people found that the full moon may affect sleep differently in males and females. Many females sleep less and have less REM sleep when the full moon phase is near, whereas males have more REM sleep close to a full moon.

A full moon affects females in different ways depending on their stage of life. For example, during puberty, a full moon can increase the production of estrogen, which can lead to increased breast size and other changes. Additionally, during ovulation, a full moon can increase the chances of conception. Younger females also tend to be more active during a full moon, while older females may feel more relaxed.

Can a man sense when a woman is on her period?

Great news! A recent study in the journal Ethology reveals that men can detect from a woman’s voice whether she is menstruating. Psychologists Nathan Pipitone from Adams State College and Gordon Gallup from SUNY Albany recorded 10 women counting from one to five, at four different points in their menstrual cycles.

There is no one definitive answer to this question. Some women may experience more sensitivity during their period, while others may not. Some men may be better at sensing when a woman is on her period, while others may not be so good. Ultimately, it is up to the woman to decide when she is comfortable discussing her menstrual cycle with a potential partner.

What should you not do on a full moon?

Seek new beginnings. “This is a time of releasing, welcoming closure, and allowing things to complete,” says Alejandrez-Prasad. Initiate intense discussions. Consume mind-altering substances. Overextend your schedule. Rush the process.

You should not do anything that could cause harm to yourself or others on a full moon. Because of the extra energy that is present, it is easy for things to go wrong. It is also a good time to clear out any old energy that you may have been holding onto, so make sure to get rid of any harmful items or people. Finally, it is a good time to focus on your own personal growth and development.
