Glass = Blue Light Toxicity 🪟💡

Most people think sitting by a window is “natural light.”

But glass acts like a filter: it blocks the healing UV & infrared… and lets the blue light straight through.

That means:
❌ No UVA to set circadian rhythm
❌ No UVB for vitamin D
❌ No infrared for EZ water + mitochondria

✅ BUT plenty of unbalanced blue light → circadian chaos, eye strain, fatigue, mood crashes

So behind glass, you’re essentially overdosing on blue light while starving for the rest of the spectrum.

If you work indoors:
☀️ Get outside for at least 5–10 min of direct morning light.
👓 Use blue blockers indoors after sunset.
🌱 Take breaks outdoors during the day—your biology doesn’t count “window light.”
💡 Add red/infrared light (incandescent bulbs or IR panels) to balance indoor light.

Your body wasn’t built for filtered light. It was built for full spectrum sunlight.

Two 3-Minute Red-Light Sessions Tackle Myopia—Long Term
A new meta-analysis of repeated low-level red-light (RLRL) therapy—typically 650 nm, 3 min, twice daily—found sustained control of childhood myopia versus standard care: axial eye growth slowed by −0.22 mm at 6 months, −0.30 mm at 12 months, and −0.61 mm at 24 months, with parallel improvements in refraction (+0.40 to +1.33 D) and thicker choroid; effects were stronger with more severe baseline myopia and higher session frequency.
Imagine what would happen if kids spent more time outside and less time on screens?

A strong circadian rhythm isn’t just about sleep — it’s the foundation of nearly every aspect of human health.
Your body is governed by clocks. Every single cell has its own clock gene that regulates metabolism, repair, and function. These peripheral clocks sync to the master clock in the brain called the suprachiasmatic nucleus (SCN).
The SCN receives direct input from the eyes through the retinohypothalamic tract. Specialized light-sensitive proteins in the retina, called melanopsin receptors, detect the amount of blue-wavelength light in the environment. These receptors don’t form images — instead, they act as precise timekeepers, sending signals to the SCN about the time of day.
With this information, the SCN orchestrates daily rhythms across the entire body — from hormone release, digestion, and immune function, to mitochondrial energy production and cellular repair.

The problem? Most of us spend our days under artificial, unbalanced blue light (LEDs, screens) and our nights exposed to light when we should be in darkness. This disrupts signaling to the SCN, suppresses melatonin by up to 80%, and elevates nighttime cortisol. The result: poor sleep, impaired repair, and the “wired but tired” state so many people feel.
Chronic circadian disruption has been linked to immune dysfunction, metabolic disease, cardiovascular problems, neurodegeneration, gut dysbiosis, anxiety, depression and more!
The good news? Because the circadian system is light-driven and highly adaptive, it doesn’t take long to re-entrain your rhythms. By aligning your light environment with nature’s cycles, you can restore balance, optimize energy, and activate the body’s innate repair programs.
❄️ That’s exactly what we’ll do in the Prep for Winter Challenge ($19) — 19 days of short, powerful lessons designed to reset your circadian rhythm, learn how to heal with the increased cold and darkness, and help you thrive all winter long. Plus, a live Q&A and a chance to win prize packages worth nearly $2000!

Hmmmmmm so vitamin D supplementation shows little to no benefit………. I’ve only been saying this for years………

💡 Vitamin D supplements ≠ the full picture.
The VITAL trial (NEJM) shows that just taking vitamin D doesn’t lower cancer or heart disease risk. Why? Because your body makes active vitamin D only when sunlight hits your skin. ☀️
Supplements can raise blood levels, but without light, the cellular effects aren’t the same.

“In this issue of the Journal, LeBoff and colleagues report findings from an ancillary study of the Vitamin D and Omega-3 Trial (VITAL),3 which extend the results of that trial; taken together, VITAL and this ancillary study show that vitamin supplements do not have important health benefits in the general population of older adults, even in those with low 25-hydroxyvitamin D levels”

Vitamin D supplements are missing the one critical piece that your body is needing………… LIGHT!!!!!!!

Vitamin D is a solar derived hormone. It carries a very specific signal to cells.

You CANNOT supplement specific light encoded frequencies.

Everyone needs to see this

Patients navigating the highways of centralized medicine are on the road to nowhere, and they're trying to escape. The escape route is through their light environment. None of their centralized MDs know this.

The decentralized truth is out there.
It is not to be found among the centralized experts in healthcare.
It cannot be found by reading the research or the guidelines.
But it is out there if you look hard enough.
