Hormone Health 30
30-day deep dive on estrogen, progesterone, cortisol.
If Cycle Literacy 101 teaches you the map, Hormone Health 30 takes you under the hood. This 30-day deep dive explores how the major hormones of the cycle shape the way you think, feel, sleep, and relate to other people, and how the stress hormone cortisol can quietly throw the whole system off balance.
What you will learn
The course opens by introducing the key players, then spends a week each on the big relationships. How estrogen interacts with dopamine and your social brain, lifting mood and drive as it rises. How progesterone produces a calming, GABA-acting compound that helps explain why the luteal phase can feel so sleepy and soft. And finally, how cortisol, when stress runs high, can interfere with the cycle and amplify symptoms.
Who it is for
This is for the curious reader who wants more than the basics. If you have ever wondered why your mood, focus, and energy seem to move on their own schedule, this course connects those dots to the underlying neurochemistry. It is a richer, slower study, built for people who find that understanding the mechanism makes the experience easier to live with.
