Ever feel like you’re waking up as two different people depending on the week of the month? One week you’re taking on the world with total confidence, and the next, you’re second-guessing every decision you’ve ever made. It turns out, that isn’t just "you being emotional", it’s actually a sign of your brain responding to a very specific biological rhythm.

This week on Live Well Be Well, I’m sitting down with the brilliant Dr. Sarah Hill. She’s an evolutionary psychologist and the author of This Is Your Brain on Birth Control and The Period Brain. Sarah has this incredible way of explaining how our hormones like estrogen, progesterone, and testosterone, aren’t just about reproduction; they are actually "wise advisors" that shape how we think, who we’re attracted to, and how we show up in our work and relationships.

Here’s what we explore together:

- Your Hormones as Information: How these biological signals act as internal guides for your behavior and motivation.

- The "Two Advisors" Theory: Why feeling different across your cycle actually makes you a better, more well-rounded decision-maker.

- The Power of Progesterone: Why this often-ignored hormone is actually a neuroprotective "superpower" that helps your brain slow down and recover.

- Cycle Variability: Why your "symptoms" can change every month based on everything from sleep to stress.

- The Male Perspective: A fascinating look at how men’s testosterone is actually more reactive to the environment (like sports or competition) compared to the predictable cycles of women.

- Bridging the Cultural Gap: How to stop overriding your body’s natural cues in a world that expects you to be the same person every single day.

Love,

Sarah Ann 💛
