Is there any relationship between the lunar phases and the menstruation cycle?

The connection between the lunar phases and the menstruation cycle has been debated for centuries.

While some people believe in the relationship between the moon and menstruation, others consider this connection to be simple superstition.

In this article, we will explore the science behind this theory and examine if there is any real relationship between the two. But first we want to leave you here the reasons why you sometimes have a delayed menstrual period .

To understand this possible connection, it is important to understand how the menstrual cycle works.

The menstrual cycle is a natural process that occurs in the body of people with reproductive capacity. Sometimes it is usually accompanied by constipation and here we explain the causes .

The cycle begins on the first day of menstruation and lasts approximately 28 days. During this time, the body prepares for ovulation, in which the ovary releases a mature egg.

The theory behind the lunar phases and the menstruation cycle

The moon has long been considered a magical and mysterious object, and people may be looking for patterns where there are none.

In addition, the duration of the lunar phases does not exactly coincide with the duration of the menstrual cycle. The average menstrual cycle is 28 days, while the lunar phases last 29.5 days. This means that the phases of the moon will not always coincide with a woman's menstrual cycle.

According to theory, the lunar cycle can affect the release of reproductive hormones in the body, which can influence the timing of ovulation and therefore the length of the menstrual cycle.

It is also believed that some people may experience heavier or more painful menstruation during more intense lunar phases, such as the full moon or new moon.

Likewise, some people may find it helpful to follow the lunar calendar and connect with their menstrual cycle in this way. Regardless of personal belief, it is important to remember that every body is different and may respond differently to moon phases and other environmental factors.

Why might the lunar and menstrual cycles be related?

It is interesting to consider the possible relationship between the lunar and menstrual cycles, since the average duration of both cycles is practically the same.

Although there is no conclusive evidence to support this connection, some have proposed theories suggesting that the lunar cycle could influence the menstrual cycle.

The idea has been put forward that moonlight, especially in the absence of artificial light, could have an impact on our biological processes.

This theory is not far-fetched, since it is known that light can affect the body and reproductive system of people. However, it is important to keep in mind that more research is still required to confirm any relationship between both cycles.

We know that people who work night shifts have a greater tendency to experience irregular cycles, possibly due to light exposure.

Additionally, there are studies that suggest that mimicking lunar light patterns can improve cycle regularity.

People's hormones may also be affected by changes in light during different seasons, as is known in conditions such as Seasonal Affective Disorder, which is believed to be related to the hormone melatonin.

The cultural and personal importance of the moon and menstruation

There are several evolutionary theories that speculate on why the length of the human menstrual cycle evolved to be similar to the length of the lunar cycle. In addition, we find stories and beliefs that connect both cycles in different cultures and mythologies.

In fact, the term "menstruation" comes from the Greek and Latin words meaning month (mensis) and moon (mene).

Many people still observe a relationship between the lunar cycle and menstruation due to its personal importance. It is an aspect that varies from person to person and has a unique connection in each individual.

But can the phases of the Moon affect menstruation?

Although there are many people who believe that there is a relationship between the lunar phases and the menstrual cycle, there is not enough scientific evidence to prove this claim.

Although some women may notice coincidences between the lunar phases and their menstrual cycle, these cases are insufficient to determine a causal relationship between both events.

After researching, we realized that there are no scientific studies that conclusively demonstrate a relationship between the lunar phases and the menstrual cycle. What we do know is that there are very current applications so that you have a closer menstrual control and can know exactly when you will be on your days.

The University of Oxford specialist, Marija Vlajic Wheeler, analyzed dates of the start of the menstrual cycle in 1.5 million women with the Clue application to find some relationship between both events. The study was recently published and was carried out for three years as a postdoctoral fellow at the Leibniz Institute for Astrophysics in Potsdam, Germany.

The results showed that there was no significant relationship between the lunar phases and the menstrual cycle.

Despite this, many people believe in the connection between the moon and menstruation and use the lunar calendar to track their menstrual cycle.

There are also some spiritual practices and rituals that are based on the connection between the moon and menstruation, such as women's circles and moon baths.

Although there is a historical and cultural connection between both events, science has not conclusively demonstrated a real relationship.

Furthermore, we want to remind you that the menstrual cycle is regulated by numerous hormonal factors, such as progesterone and estrogen, and the moon has no effect on these processes.

However, we have read that some people maintain that the moon can indirectly affect the menstrual cycle by influencing other aspects of daily life, such as stress and sleep quality.

But these effects are difficult to measure and evaluate, and there is no solid evidence as we already told you before.

Important information

• After analyzing more than 7.5 million cycles, it is concluded that the menstrual cycle is not synchronized with the lunar cycle. Coincidence between the lunar and menstrual cycles occurs in certain cases, depending on the affinity between a person's average cycle length and the lunar cycle, as well as the variability in the length of their menstrual cycle.
• The lunar cycle and the average menstrual cycle have a practically similar length.
• The term "menstruation" comes from the Greek and Latin words for month (mensis) and moon (mene). On many occasions, we have been asked to include lunar cycles in applications like Clue .
• To address this question scientifically, we performed calculations and concluded that the menstrual cycle does not synchronize with the lunar cycle, based on the analysis of more than 7.5 million cycles.
