The Follicular Phase — The Starting Point of Our Strength
The beginning of a period is a highly individual experience. However, most of us are used to viewing the start of the cycle as a time to curl up in a ball, drink hot tea, and wait for it all to be over. I am no exception for the first two days; after that, it gets easier both emotionally and physically.
But if we look “under the hood” of our physiology, we discover that right now, a powerful engine of renewal is starting up.
Welcome to the follicular phase.
During my second year at the Open University, while studying women’s support in sports, I first encountered this term. I was curious about the logic behind the name.
The name comes from the Latin word folliculus, meaning “little bag” or “bubble.” If you are at the beginning of your cycle, then right now, as you read this, dozens of these microscopic bubbles are waking up in your ovaries. Inside each one sleeps an immature egg.
With the first day of your period, your brain sends a command: “Time to prepare for new life!” Follicle-stimulating hormone (FSH) is released, and these bubbles begin to grow. It’s like a startup incubator: they compete until one dominant follicle emerges. In two weeks, this “winner” will release an egg during ovulation.
Why are we metabolically most similar to men right now?
Our main female hormones — estrogen and progesterone — are currently at their lowest point. This creates a unique window of opportunity:
- Carbohydrate Drive: When estrogen is low, the body burns glycogen (sugar) for energy much more efficiently. This is the perfect time for high-quality carbohydrate fueling: whole grains, starchy vegetables, legumes, fruits, and berries.
- Energy Efficiency: The body allocates energy precisely without storing everything “just in case.” We become physiologically more resilient to physical stress (once the acute pain subsides).
- Cooler Temps: Our basal body temperature is at its lowest for the month. We overheat less, which allows for more intense work if the resources are there.
So why do we still feel tired?
If we are so “strong,” why do we want to sleep? Because the body is performing colossal mechanical work. The uterus contracts under the influence of prostaglandins to shed the endometrium. This consumes a massive amount of internal resources. Furthermore, blood loss leads to a temporary drop in iron and oxygen levels.
What to do? (Advice from Dr. Stacy Sims, author of “Roar”):
- Rest is Productive: Don’t try to be a “superwoman” if your body asks for peace. You aren’t “broken”; you are in reboot mode.
- Fueling: Don’t fear complex carbohydrates. Today, they are your best friends.
- Space and Gravity: Try Malasana (Garland Pose). This isn’t about “sport”; it’s about creating space. It helps relieve spasms, relaxes the lower back, and lets gravity assist your body in the cleansing process.
We aren’t just “getting through” these days. We are laying the foundation for an energy peak that will arrive in just a few days.
There is an entire universe inside you. Let’s strive to be part of this universe by understanding its processes and choosing the right actions for our bodies.
