What is the Menstrual Cycle?

The menstrual cycle is a monthly process that occurs in every woman’s body, preparing it for pregnancy. The cycle typically lasts about 28 days but can range from 21 to 35 days. It consists of several phases:

1. Menstrual Phase: The shedding of the uterine lining, which is experienced as menstrual bleeding. This phase lasts about 3 to 7 days.

2. Follicular Phase: It overlaps with the menstrual phase initially. The pituitary gland releases follicle-stimulating hormone (FSH), promoting the growth of ovarian follicles. One follicle will mature and produce estrogen, which helps rebuild the uterine lining.

3. Ovulation: It occurs around the middle of the cycle (day 14 in a 28-day cycle). The mature follicle releases an egg (ovum) into the fallopian tube. This is the most fertile period of the cycle.

4. Luteal Phase: After ovulation, the empty follicle transforms into the corpus luteum, which secretes progesterone to prepare the uterine lining for a potential pregnancy. If fertilisation does not occur, the corpus luteum deteriorates, leading to a decline in progesterone levels and the onset of menstruation.

These phases are regulated by hormonal changes and can vary from person to person.

What are the issues faced by women during Menstrual cycles? 

During the menstrual cycle, many women experience a variety of symptoms and challenges, including:

1. Cramping: Extreme pain, continuous or in intervals in the lower abdomen, including thigh pain, back pain, headache, etc.

2. Bloating: Fluid retention can result in abdominal bloating and a feeling of fullness.

3. Breast Tenderness: Hormonal changes can cause breasts to feel sore, swollen, or tender, and many times, nausea can accompany this.

4. Mood Swings: Hormonal fluctuations can affect mood. Mood swings are very common.

5. Fatigue: Many women feel unusually tired or fatigued during their menstrual cycle.

6. Headaches: Hormonal changes can trigger headaches or migraines.

7. Digestive Issues: Changes in hormones can affect digestion and eating habits.

8. Acne: Hormonal changes can increase oil production, leading to breakouts or worsening of acne.

9. Difficulty Sleeping: Hormonal changes and discomfort can disrupt sleep patterns.

10. Weakness: Due to the continuous bleeding phase and daily tasks, many women tend to feel physically drained and tired.

These symptoms are more or less faced by every woman. But if they are severe, a consultation with the doctor or gynaecologist is required.

Why is it important to keep track of your Menstrual cycle?

Monitoring your menstrual cycle is beneficial for various reasons:

1. Health Monitoring: Tracking can help identify irregularities, such as changes in cycle length or abnormal bleeding, which can indicate underlying health issues like hormonal imbalances, polycystic ovary syndrome (PCOS), or thyroid problems.

2. Fertility Awareness: For those trying to conceive or avoid pregnancy, tracking ovulation and cycle patterns can help determine the most fertile days or the need for contraception.

3. Symptom Management: Monitoring symptoms like cramping, mood swings, and fatigue can help manage and prepare for them. It also aids in recognising patterns that might require medical attention or lifestyle adjustments.

4. Medication and Treatment Planning: Accurate tracking can help doctors make informed decisions about treatments for conditions such as PMS or endometriosis and adjust medications or therapies as needed.

5. Personal Awareness: Understanding your cycle can improve self-awareness and enable better planning for activities and responsibilities around your period.

Overall, tracking helps manage reproductive health more effectively and supports better overall well-being.

The Lunar Cycle

The lunar cycle consists of several phases, including:

1. New Moon: The moon is completely dark and invisible from Earth, signifying the start of a new lunar cycle.
2. Waxing Crescent: A thin crescent of the moon emerges, gradually increasing in size.
3. First Quarter: Half of the moon is illuminated, and it appears as a half-circle.
4. Waxing Gibbous: The moon is mostly illuminated, growing larger in appearance as it nears its full phase.
5. Full Moon: The moon appears in its entirety, a perfectly round orb.
6. Waning Gibbous: The moon begins to decrease in illumination after the full moon.
7. Last Quarter: Again, half of the moon is illuminated, but it is the opposite half compared to the first quarter.
8. Waning Crescent: A small portion of the moon is visible as it gradually disappears, leading to the new moon.

The lunar cycle lasts about 29.5 days, which is similar to the average menstrual cycle length of about 28 days. This similarity has led to speculation about potential synchronicity between the menstrual cycle and the moon phases.

History Of the Belief: Are Menstrual Cycles Affected by the Moon?

Traditional societies have often viewed the connection between menstrual cycles and the moon as significant, attributing various meanings and beliefs to this relationship. Here are some key perspectives from different cultures:

Ancient Greek Beliefs

In Ancient Greece, the word “menstruation” was derived from the Greek word for moon, “mene.” Greek philosophers, such as Aristotle, believed that women’s menstrual cycles were influenced by the moon. Aristotle suggested that menstruation tended to occur during the waning moon, as this phase was thought to be cooler and more humid, making it a natural time for women’s bodies to shed their uterine lining. This belief linked women’s reproductive health to celestial movements, suggesting a spiritual and physical connection to the moon.

Indigenous Cultures

Many Indigenous cultures also recognise a connection between the menstruation cycle and the moon phases. For instance, in the Ojibwe tradition, menstruation is referred to as “moon time.” During this period, women are encouraged to take time for rest and reflection, as they are believed to possess heightened spiritual power. Patty Smith, a member of the Leech Lake Band of Minnesota Ojibwe, emphasises that as women menstruate, they release accumulated experiences and stress, which is considered a powerful and sacred process.

Similarly, the Yurok tribe in California holds a strong belief in the significance of “moon time.” Women traditionally isolate themselves during menstruation to focus on spiritual practices. They believe that being in sync with the moon enhances their spiritual power, and if a woman feels out of sync, she may seek to reconnect by sitting in the moonlight and communicating with the moon.

Hindu and Buddhist Traditions

In Hindu and Buddhist cultures, there are also beliefs linking the menstruation cycle and moon phases. In Ayurveda, the traditional Indian system of medicine, it is believed that blood (rakta) is governed by the moon (Chandra). Women are considered healthier when their menstrual cycles align with lunar rhythms. Ancient texts, such as the Vasishtha Samhita, describe women as having a lunar nature, while men are associated with solar qualities. This reflects a broader understanding of how natural cycles influence human health and behaviour.

Modern Rituals and Spiritual Practices

In contemporary society, some rituals continue to connect menstruation with moon phases. For example, gatherings known as “The Red Tent” encourage women to come together during the new moon to share experiences and bond. This modern practice echoes ancient traditions where women would retreat during their menstrual cycles to focus on communal support and spiritual growth. However, in India, it is believed that women should not do spiritual practices during menstruation, and some folks still believe that it is impure. But change is happening. The tradition was started for women to rest and focus on their bodies and health more during menstrual bleeding so as to avoid any complications or health issues women often face during menstruation.

Does The Moon Cycle Affect Menstrual Cycle?

A recent study, commissioned in 2016 by the company that programmed the period-tracking app Clue, concludes that synchrony between the menstrual cycle and the moon phases is a “myth.” This research, which analysed over 7.5 million menstrual cycles, suggests that periods most likely do “not sync with the lunar cycle.” One of the prominent reasons to believe that the moon does not sync with the menstrual cycle is the period of the cycle being the same. A menstrual cycle covers 28 days, while the lunar cycle takes 29.5 days.

Early Studies:

Various studies have explored the potential link between the menstruation cycle and moon phases. One notable study conducted by Sung Ping Law in 1986 found that a significant number of women menstruated around the new moon. However, this finding has been met with scepticism and has not been consistently replicated.

Contradictory Findings:

More recent studies have challenged the idea of synchronicity. A comprehensive study examining 1.5 million menstrual cycles found no discernible connection between the timing of menstrual periods and lunar phases. The researchers observed that periods occurred at random intervals throughout the month, independent of the moon’s cycle.

Recent Research:

Despite the prevailing notion that there is no link between the two cycles, a small-scale study published in 2021 revealed intermittent synchronicity. This study monitored the menstrual cycles of 22 women over an extended period, finding that those with longer cycles exhibited some synchronisation with lunar phases, particularly the full moon. However, the researchers cautioned that their findings were preliminary and required further validation through larger-scale studies.

Ancient Beliefs:

In ancient times, many people believed that the menstrual cycle was influenced by the moon. For example, some philosophers, like Aristotle, thought that women’s periods were more likely to happen during certain phases of the moon. This belief was based on the idea that human bodies are connected to nature’s rhythms.

Cultural Connections:

The term “moon cycle” is often used to refer to menstruation. Many languages have words for “moon” and “month” that are related, showing how closely these concepts are linked in people’s minds. In various cultures, women have been associated with the moon, which is often seen as a symbol of change and cycles.

Influence of Moonlight:

One theory about the connection between the moon and menstrual cycles is that moonlight may affect hormone levels. The brightness of the moon changes throughout its phases, which could influence how hormones work in the body.

Melatonin and Menstrual Health:

Melatonin is a hormone that helps regulate sleep and can also affect menstrual health. If moonlight impacts melatonin levels, it could potentially influence menstrual cycles. However, this idea is still being studied, and more research is needed to understand the relationship fully.

Analysing the Data

Coincidence vs. Correlation

Many studies suggest that any overlap between the menstruation cycle and moon phases is likely due to chance. Since the average menstrual cycle is similar to the lunar cycle, it is expected that some people will have their periods around the same time as the new or full moon purely by coincidence.

Importance of Sample Size

The differences in study results can often be attributed to sample size. Smaller studies may show significant results, but they may not be strong enough to draw firm conclusions. Larger studies, like the one involving 1.5 million cycles, provide more reliable evidence against the idea of synchronisation.

Myths and Misunderstandings

The belief in a connection between menstrual cycles and lunar phases can lead to myths and misunderstandings about women’s health. These beliefs may cause women to feel pressure to have regular cycles that align with the moon, which is not realistic for everyone.

Empowerment Through Knowledge

Understanding the menstrual cycle can help women feel more confident about their health. Education about menstrual health can help dispel myths and encourage a better understanding of how individual cycles work.

Conclusion

So, does the moon affect the menstrual cycle? Do menstrual cycles sync with the moon? Are Menstrual cycles and the full moon connected? Here’s the conclusion, the relationship between the menstrual cycles and the moon is an interesting topic that has been studied for many years. While historical beliefs and cultural stories suggest a connection, modern research shows that any synchronisation is likely coincidental. The variability of menstrual cycles, influenced by many factors, complicates the idea of a connection with lunar phases.

In India, the menstrual cycle was suggested as impure, and the women were not allowed to visit temples and to do spiritual practices, or even to move freely in the household. However, times are changing as more education about the menstrual cycle and the female body is provided in schools. It was traditionally used to help women rest during the bleeding phase and help them keep their health stable while dealing with various issues that the menstrual cycle brings. According to ancient beliefs, spiritual practices might have brought synchronisation, but that is not the case for everyone. Everybody is different while functioning the same.

Your healthy cycle means you are healthy. It is not necessary to sync with the moon. As research continues, it is important to approach this topic carefully and to value both scientific evidence and cultural beliefs. Ultimately, understanding the menstrual cycle can empower individuals to embrace their unique rhythms and promote a healthier view of menstrual health.

Irregular menstrual cycles can signal potential health problems, such as hormonal imbalances or reproductive disorders. These conditions can significantly affect a woman’s well-being and often necessitate medical intervention. Unfortunately, access to healthcare, especially for menstrual-related issues, can be challenging due to financial constraints. If you or someone you know is facing any of these issues, you can start a fundraiser on Ketto to raise funds for treatment. Moreover, by contributing to these initiatives, you can help women access the care they need to improve their overall well-being.
