Do you feel your timing is off? That the 24-hour day somehow doesn’t have enough time in it to complete the ever-mounting to-do list? All day, every day, we are to push ourselves to the limit to produce and create, causing us to overstretch, overexert, and overwhelm. For those with vulvas, this might feel especially true. Why? Chances are you’re living on the wrong clock.
Women’s hormone expert, Alisa Vitti, wants you to jump onto the right clock, the “right-timing” as she says. She is speaking about your infradian rhythm, the lengthier sister to the 24-hour day cycle The infradian rhythm, also known as your menstruation cycle, consists of around 28-days and takes place over four phases, each with its own change in brain chemistry and optimization for different things from nutrition and exercise to communicating, rest, and productivity.
In her book In the Flo: Unlock Your Hormonal Advantage and Revolutionize Your Life, Vitti presents her decades of research. Vitti is, understandably so, furious with how the world has failed her and every other vulva-owner by not prioritizing this incredibly important aspect of their bodies and lives.
During one’s menstruation cycle, many changes occur in the body. In a small breakdown of the infradian rhythm, Vitti demonstrates how our metabolism speeds up and slows down predictably across the month and that you need to change what you eat and the intensity of your workouts each week in order to optimize your metabolism. Indeed, your cortisol levels are higher in one part of your infradian rhythm, so pushing yourself through intense workouts (which already creates cortisol) only increases the stress and inflammation in the body, adding to the anxiety and lack of focus.
So how do we jump onto this “right timing”? Start by tracking your cycle and following Vitti’s anagram POWR—Prepare, Open Up, Work, Rest—to know what to do in each cycle.
