The Moon and Your Cycle - Are They Connected?

Do you believe your period is related to the phases of the moon? It may sound a bit strange, but there’s long been theories that women’s menstrual cycles are synced up with the moon’s 29.5 day cycle. That’s why so many cultures associate the moon with fertility.

And if you’ve been watching the sky with any interest these days, you may know that something special is on the horizon: A Supermoon. And not just any Supermoon. A Strawberry Supermoon. 🍓

What is a Supermoon?

A supermoon is a full moon that orbits really closely to Earth, so it looks enormous and magical. On the evening of Tuesday, June 14th, just after sunset, you’ll see the next Supermoon and it will appear with a golden colour! 

Naming these moon phases come from a lot of different places including Native American, Colonial American and European sources. June’s full moon, which is typically the last full moon of spring or the first of summer, has traditionally been called the Strawberry Moon. It’s also known by lots of other names like the Blooming Moon, the Birth Moon, The Egg Hatching Moon and the Honey Moon. 

All you need to know is that it’s going to be a spectacular sight, so make a night of it. Get outside and enjoy an early summer evening under the glow of the Strawberry Supermoon. 

Are our cycles actually linked to the moon? 🌝

The research is split. 

The moon’s influence on our cycle has largely been dismissed as a myth, but interestingly, some studies have linked lunar phases with sleep and moods. We know there is a link between our cycle and sleep (we wrote about it here) so it’s interesting to wonder whether our body is working in sync with the moon in this way! In a study published in Science Advances, researchers looked at long-term data from women and found that for some, their periods actually synced up with lunar cycles at certain times of their lives. 

The study also showed that with age and exposure to artificial nocturnal light, their cycles shortened and stopped aligning with the moon. The researchers behind this study think that this is because in ancient times, human reproductive behaviour was aligned with the moon but artificial light (from lights and screens) and our modern lifestyles have actually changed reproductive physiology and behaviour. 

It would be easy to dismiss this as a coincidence. After all, the data only studied 22 women over the course of 32 years. There were bound to be some instances where things aligned purely out of chance. 

And this is exactly what more recent research from Clue demonstrated rather definitively. Their conclusion? The menstrual cycle does not sync with the lunar cycle. The study was based on the 7.5 million cycles so it’s hard to argue with. The lunar cycle and the average menstrual cycle are basically equal in length so these cycles will inevitably correlate at certain points for some people. They’ve also noted that the terms “menstruation” and “menses” come from Latin and Greek words meaning month (mensis) and the moon (mene) so the association is understandable.

The cultural significance

While the science is somewhat inconclusive, many cultures believe there is a link to our cycles and the moon. For example, in the Ojibwe tradition, menstruation is known as “moon time.” (Cute, right?) Traditionally, women take refuge in their homes while they have their period to rest and reflect. Maybe we could learn a thing or two here! 

Similarly, many Hindu and Buddhist traditions also say there is a link between the lunar cycle and menstruation. According to Ayurveda, blood is believed to be governed by Chandra, the moon. Women were believed to be healthier when their cycles were in sync with the moon. 

Our take

We think there’s something really magical about the idea that our body is working in sync with nature. Despite the fact that many studies refute the idea of a connection, there are countless cultures that have found meaning in the link between menstruation and the phases of the moon. 

So we say go ahead: track your cycle’s relationship with the moon. If nothing else, it might be a way for you to feel more connected to your body and the universe.
