Quantum Terrain Theory + Live group coaching

Hi Reader, The mission of light-based health and wellness continues! This month has seen a new podcast interview come out about my work with IAQB and QBC, a new table of contents for the hundreds of post in my Substack now organized by Category!!!, and the first member meetup and open Q&A inside the paid tier at Brighter Days, Darker Nights (click here to attend the live group coaching session coming up on December 11th at 1 PM Pacific). Catch up on what you missed: Quantum terrain theory...

Hi Reader, I just finished getting the replay of my recent Quantum Breastfeeding class up and out to everyone who signed up to attend live. I sent the link out to everyone who attended (email me if you can’t find it), and it’s also inside the membership at Brighter Days, Darker Nights (flash sale now). If you’re not in either of those groups, you can get it a la carte below. Quantum Breastfeeding Replay The class ended up lasting about 2 full hours, and all the goodness is included in the...

WHAT'S NEW 1-1 SUBSTACK INSTAGRAM BOOK (coming soon!) Breastfeeding is both ancient and ever-evolving in the face of new influences like artificial light, EMFs, and EDCs. I find it fascinating that breast milk is a circadian signal, and that nurturing maternal rhythms improves the milk. It can be rich with melatonin, endocannabinoids, and other rhythms shaped by light and season. Yet under-supply, oversupply, and supplementation remain confusing in today’s modern environments. This live class...

Many, many people have been asking for more guidance around breastfeeding and wondering if a quantum approach could help them resolve their challenges. So, I am putting on a class to share how to use quantum supports others may be overlooking. Quantum Breastfeeding The class is for both parents and practitioners and will take place live on October 16th, 2025 at 1:00 PM Pacific / 4 PM Eastern. It is free for all paid subscribers of my Substack, and guest tickets are available for $25 (includes...

WHAT'S NEW 1-1 SUBSTACK INSTAGRAM BOOK (coming soon!) Love it or hate it, the cold season is coming to the Northern Hemisphere. Here are a few resources to help turn the season change into a health ally. Prep for Winter Over inside my Substack, I’ve put out a trio of posts on this topic. Seasonal methylation and folate metabolism patterns How to use the season shift to end lactational amenorrhea and/or optimize body weight The different mitochondrial responses to heat and cold therapy Plus:...

Have you noticed it? That early fall crash? The one where kids suddenly start melting down about bedtime (even though bedtime used to be smooth). Parents feel like they have to scramble; schedules all feel at a breakneck pace. Sleep gets rocky, and you just have to wonder: is it the new routines or is Fall just destined to be this way? But it’s not just back-to-school stress, because if it were, it would only be affecting those going back to school. Since it does affect the majority of people...

Hi, My colleague Carrie B. is going to be teaching a webinar about the summer hormones and I thought you might be interested in it. Here’s the scoop: Live Webinar — How to Boost Vitamin D & MelatoninWednesday, August 27, 20251:00-3:00pm ET About the webinar: Vitamin D and melatonin are critical to your health, but nearly everything you’ve been told about them is backwards. You’re told you’re “low” on vitamin D while being told to fear the very sun that creates it. You’re handed melatonin...

This week, I got to have a chat with my quantum friend Amanda! She is an expert in primitive reflex integration, rhythmic movement training, and—of course!—quantum health. And so much more. Watch or Listen Now The replay is live on Brighter Days, Darker Nights with my other interview recordings. Watch or Listen PS Early Bird for my upcoming Fertility Circle will close on August 1st.

Hi! Here’s a quick invitation to sit in (virtual) circle with me to explore fertility through the quantum lens. Fertility Circle in August, 2025 Spaces will be limited to make sure there is time for everyone to share and ask questions about using quantum health practices to support fertility. Join the Fertility Circle interest list Bonuses include lifetime access to my practitioner lessons on the topics of male and female fertility, my research compendium with the perinatal research addendum...

“Big doors swing on little hinges” is a common metaphor used to describe the goal of quantum health. Last year, when explaining quantum health, I used this colloquial definition quite a bit. At that time, I was especially interested in understanding redox, which can be thought of as the balance of: oxidative vs antioxidant forces positive vs negative charges protons vs electrons acid vs alkaline (yes, these are all different ways of exploring very similar concepts) More in my recent post: 💬...
