687: The Period Brain: Why You Feel Like a Different Person Every Month And How To Stop Fighting Your Cycle and Start Thriving in It with Sarah Hill

47 minutes

If you’ve ever felt like you’re riding a menstrual cycle roller coaster of cravings, exhaustion, and mood swings– this conversation is for you.

In this episode, I’m joined by leading researcher and women’s hormone expert Dr. Sarah E. Hill to unpack what’s really going on in your body—and your brain—during your cycle.

Dr. Hill breaks down how shifting levels of progesterone and estrogen in the second half of your cycle can impact everything from your sleep and appetite to your mood and libido.

We also talk about how this becomes even more complex—and important to understand—during perimenopause, when hormone patterns start to change unpredictably.

You’ll learn why traditional health advice often fails women during this phase of life, and what to do instead to actually support your body.

It’s time to rethink your period, reclaim your energy, and finally feel in sync with your hormones!

QUOTES

“The week– or for some women, it's even the full two weeks– of the luteal phase can be a really challenging time emotionally as their body is struggling to keep up with those wild swings and hormones. But then also as you go into perimenopause, you're going through a period of intense hormonal change, and unlike what goes on across a regular cycle, it's unpredictable.”

“Women are twice as likely as men to have mental health-related illnesses. They're more than twice as likely as men to be diagnosed with anxiety. They're more likely to experience burnout in the workplace. I mean, the list goes on, and it's because there's way too much that's expected of us. And one thing that women don't recognize about it is that in addition to this being bad for things like cardiovascular health… it can also prevent you from even producing sex hormones.”

“A big part of The Period Brain is first, just really giving women a roadmap to the second half of their cycle, since it's not something that's really talked about.”
