322: What Your Skin Is Trying to Tell You About Your Health–The Neuroscience Behind Beauty Sleep, Acne, & Glowing Skin
#322: What if your skin knows you're stressed before you do? If you've ever broken out before a big event, been told you "look tired," or wondered why your skin seems to reflect exactly how you're feeling, this episode will completely change how you think about skincare. Josie sits down with neuroscientist Dr. Claudia Aguirre to explore the hidden conversation happening between your brain and your skin. Dr. Claudia explains the fascinating science behind why stress shows up on your face, how your skin has its own stress response, why beauty sleep is actually real, and the surprisingly powerful ways your daily rituals can calm your nervous system and support healthier skin. Whether you're struggling with acne, chasing healthier skin, or simply trying to feel less stressed, this conversation will leave you looking at your body—and your skincare routine—in a completely different way.
You'll learn:
Why your skin can produce its own cortisol, melatonin, and even endorphins
The surprising reason stress can trigger breakouts almost instantly
The shocking brain-skin connection you've probably never heard before
How chronic stress accelerates skin aging and inflammation
The science-backed habits that support both brain health and glowing skin
