Before we flipped a switch on darkness, our bodies kept time with the sun, the moon, and the fireside.

Light is the oldest instruction our biology ever received. For a couple hundred thousand years, human light had four features: very bright days, very dark nights, gradual transitions at either end, and a seasonal swing across the year. Every cell we have was built around that pattern. Then, we replaced all four of those features with nearly 93% of our time now spent inside, and never really asked what we were trading.

This episode is Aly and Fringe Scientific Director Dr. Genevieve Newton sitting with that question: What has artificial light quietly done to our routines, our hormones, and the ancient rhythms wired into every cell? Making a case for the darkness we lost.

Here's the silver lining: almost none of it appears to be written in stone. This is a conversation about what our ancestors conditions were, what we've done to them, and how much of it we can quietly undo in our own modern life.

What would pregnancy and postpartum look like if pelvic floor care were part of the plan from day one?

On this episode, Fringe Women's Health Director, Liz Frey, PT, sits down with Dr. Marcy Crouch, PT — better known as the Down There Doc — a pelvic health physical therapist with 15+ years of experience and a mission to make women's bodies a whole lot less of a mystery. Marcy shares the moment that redirected her entire career, why she treats "vaginas like elbows," and how her own experiences reshaped the way she cares for her patients.

Together, they dive into birth-injury prevention, why she believes information beats fear every time, what she wishes every provider understood about postpartum care, and the one message she'd give every woman before giving birth.

Honest, open, and deeply human. Exactly the kind of conversation we're here to have on The Fringe.

Speaker Bio:

Dr. Marcy Crouch, PT, DPT, WCS, is a Board Certified Women’s Health Physical Therapist, mom of two, TEDx speaker, and your internet BFF for all things down there.

Some people pick paths. Dr. Perry Nickelston, carves them out.

In this episode, Dr. Alyson sits down with her longtime friend and one of the most exciting thinkers in the health and wellness field — the self-described "lymphatic ninja" behind Stop Chasing Pain. They go all the way back to 2011 where they first started working together, but this conversation is about where Perry's work has landed 15 years later: the lymphatic system, and why it may be the most overlooked system in your body.

Dr. Perry shares his personal health journery that changed everything for him — the brain fog, fatigue, recurring infections, puffiness, and weight he couldn't shake, even while doing "all the right things." What finally moved the needle was understanding how fluid actually moves through the body, and working with it in the right order.

This episode is full blown mechanism-first thinking we love: how light supports cellular energy and lymphatic flow, why you have to be fringe enough to ask a different type of question, and why the goal isn't doing more — it's doing the right things, consistently.

What we dive into:

• Perry's journey from fascia and movement into lymphatics — and the 30-day turnaround that redirected his career. 
• What a stagnant lymphatic system actually looks and feels like. 
• Why "looking beyond the site of pain" changes your results. 
• Laser, LED, Sun — why it's all just light, and how to use it well. 
• The "snow globe" model of waste, swelling, and inflammation. 
• Tummy time, crocodile breathing, and calming the nervous system. 
• One take that transforms wellness - "More isn't better, better is better". 
• Dr. Perry's Big 6 self-care technique for improving fluid flow in the body

Speaker Bio: 

Dr. Perry Nickelston, DC is a chiropractic physician with 28+ years of clinical experience who treats chronic pain and inflammation at the source - through the lymphatic and vascular systems. He's the founder of Stop Chasing Pain and creator of the MOJO Self-Care Ceminars and Body Ecosystem Algorithms.

After healing his own severe back injury and autoimmune disease with the methods he now teaches, Perry built his work around one idea: the body's systems are meant to work together, and when you restore the flow, everything else gets better.

Dr. Perry is a certified Functional Movement (FMS) and Selective Functional Movement Assessment (SFMA) specialist and an expert in myofascial and trigger point soft tissue therapy, he also serves as a member of the Board of Directors and as Medical Staff Advisor for AIMLA (American Institute of Medical Laser Application).

Dr. Perry isn't here to simply chase down symptoms. He looks beyond the site of pain, and helps you take back control of your body.

In this episode, Dr. Genevieve Newton, PhD sits down with Dr. Anna Cabeca, DO, OBGYN, FACOG, the beloved "Girlfriend Doctor", to bring the science (and heart) to what's really happening during menopause, and why chasing symptoms in isolation rarely works.

Together they trace menopause back to the roots: inflammation, adrenal dysregulation, and hormone imbalance, what Dr. Anna calls the "devil's pitchfork." Rather than reaching for a prescription pad, this conversation explores how nutrition, lifestyle, stress, and the gifts of the natural world can help women feel like themselves again. You'll hear Dr. Anna's journey from conventional OB-GYN to functional medicine, her Keto-Green and Magic Menopause approaches, and a refreshingly honest take on hormone replacement, intimacy, pelvic health, and what it means to build your own personal "blue zone."

Speaker Bio: 

Anna Cabeca, DO, OBGYN, FACOG, is best selling author of The Hormone Fix and Keto-Green 16 and MenuPause. Dr. Anna is triple-board certified and a fellow of gynecology and obstetrics, integrative medicine, and anti-aging and regenerative medicine. She holds special certifications in functional medicine, sexual health, and bioidentical hormone replacement therapy. 

She lectures frequently on those topics and shares the secret behind the ebb and flow of intimacy as she demystifies the fascinating hormonal changes over time. She will help you discover how the “love hormone”, Oxytocin can breathe life into your relationship, and how Cortisol can take it away - and how the delicate balancing act of those hormones can reignite your libido and support a healthy relationship, most importantly the one you have with yourself.

A patient walks into a clinic with undetectable AMH, ovaries that look shriveled on ultrasound, and a single sentence:"I'm looking for a miracle." Nine months later, she conceives naturally. Then does it again.

This is the healing energy we’re bringing as we sit down with Dr. Lorne Brown, to unpack what 26 years of treating fertility has taught him.

We get into the science (and stories) behind:

• Why egg quality may actually be an energy problem
• Dr. Brown's journey to studying medical laser science for fertility.
• Why nervous system dysregulation is the missing link in modern fertility care
• How chronic stress quietly accelerates biological aging and fertility decline
• The endocrine disruptors hiding in plain sight
• The "I'll be okay either way" mindset shift that, more often than not, shows up right before the miracle.

This conversation is part science deep-dive, part field manual, part gut check. Whether you're navigating fertility, treating clients who are, or just fascinated by the intersection of ancient medicine and modern research, this one deserves a listen.

Guest Bio:

Dr. Lorne Brown, B.Sc, CPA, Dr. TCM, FABORM, CHt, is a recognized leader in integrative reproductive and hormonal health.
