The Infradian Rhythm: The Key to Understanding Your Body’s Natural Cycle

Cycle

While most of us are familiar with the circadian rhythm, which is shared by both men and women and is a 24-hour biological clock governing functions like our sleep, the infradian rhythm is unique to women and far less studied.

"Women have an important biological rhythm that has been ignored by medical, nutritional, and fitness research. It's called the infradian rhythm."

The Circadian vs. Infradian Rhythm

While most of us are familiar with the circadian rhythm, which is shared by both men and women and is a 24-hour biological clock governing functions like our sleep, the infradian rhythm is unique to women and far less studied.

In Chronobiology, an infradian rhythm has a period longer than one cycle per 24 hours, such as menstruation, breeding, tidal, and seasonal rhythms. 

When creating Mauj, we were inspired by these mirroring and intersecting rhythms, which govern both the female body and the powerful ocean tides. So, here’s a little bit more about the infradian rhythm.

The Importance of the Infradian Rhythm 

The infradian rhythm, also known as our 'second clock', plays a big role in our overall health, especially in our reproductive years. It creates a 25% change in women’s brain chemistry over the course of the month and affects our immune system, microbiome, stress response, and reproductive system.

"The infradian rhythm is one of two internal timekeepers experienced by people with female biochemistry. It is a cycle, anywhere between 21 and 35 days in length on average, that regulates the menstrual cycle. The body’s other innate timekeeper is the 24-hour circadian rhythm, which is experienced by both men and women. The infradian rhythm is only experienced by people with female physiology."

The infradian rhythm explains the fluctuations of our productivity, weight, period, health, sex drive, energy, and mood throughout a cycle. The key to optimizing our health and better flowing with these changes is to adapt how we eat, exercise, work, and live according to where we are in the cycle.
