Beyond Red Light: The New Era of Whole-Blood Photobiomodulation

Sayer Ji sits down with Dr. Chris D’Adamo—leading epidemiologist, integrative medicine authority, and author of over 90 peer-reviewed publications—to explore the fascinating science of photobiomodulation(how light influences biology).
Together, they unpack why light should be considered a nutrient, how different wavelengths—from blue and green to red and infrared—affect health, and what modern technologies are revealing about light’s healing potential.
Concise 3-Minute Summary of the Interview
“Light Is a Nutrient: The Past, Present & Future of Photobiomodulation” Host: Sayer Ji | Guest: Dr. Chris Dedamo (epidemiologist, 90+ peer-reviewed papers)
1. Big Idea
Light is not just something you see with — it’s a biological nutrient that powers ATP, repairs mitochondria, and regulates every system. Modern junk lighting + indoor life = widespread light-deficiency disease. The fix: Deliberate, full-spectrum light — especially low-level laser therapy (LLLT) delivered via the bloodstream.
2. The Science in 60 Seconds
- Light hits cytochrome c oxidase in mitochondria → ↑ ATP, ↓ inflammation, ↑ repair.
- Each colour has a job:
- Blue (daytime): ↑ nitric oxide, alertness, acne kill
- Green/Yellow: ↑ blood flow, mood, collagen
- Orange: prefrontal cortex boost, safe at night
- Red/Near-IR: deepest penetration → pain, muscle, bone
- Sun gives 40 % visible + 55 % infrared, but most adults are clothed & north of 37° latitude → zero vitamin D + zero IR in winter.
3. History in a Flash
- 3000 BC: Egyptian sun temples
- 1903: Nobel Prize for UV “light baths” curing TB
- 1960: Ruby laser invented → accidental discovery of LLLT (grew hair on shaved mice)
- 1990s: NASA grows plants with LEDs in space
- 2020s: Wearable medical-grade wrist lasers
4. LED Panels vs. Laser (the slide everyone screenshots)
| LED Panels | Endolight (LLLT) | |
|---|---|---|
| Coherence | Scattered | Perfectly aligned |
| Penetration | 1–2 cm | 8–10 cm (hits blood) |
| Treatment time | 20–60 min, naked | 10 min, fully dressed |
| Cost | $300–$1,500 | ~$1,900 (10 % off link) |
| Evidence base | 100s studies | 5,000+ studies |
5. The Star: ENDOLIGHT Wrist Laser
- 7 lasers + 1 LED (red, yellow, green, blue, near-IR)
- 280 mW total power (5× first-gen)
- Worn over radial artery → 80 % of blood irradiated in 1 hour
- 3 modes: Recharge (morning), Recover (all-day), Relax (evening)
- Built on acupuncture points + German IV-laser engineering
6. Proven Wins (human studies)
- COVID recovery: 90 % fever-free vs. 30 % in controls
- ↑ SpO₂ (oxygen saturation) within minutes
- ↑ HRV (stress resilience)
- ↓ pain, cough, headache, fatigue
7. Turbo-Charge with Photodynamic Therapy (PDT)
30–60 min BEFORE light:
- Blue → riboflavin (B2)
- Green → red seaweed
- Yellow → spirulina / hypericin (St John’s wort)
- Red/NIR → chlorophyll or methylene blue
8. Daily Protocol (what Chris & Sayer actually do)
- Sunrise: 10 min “Recharge” (red+IR) + coffee → skip the jitters
- Work: 2–3 cycles on wrist while typing
- Sunset: “Relax” mode (green+blue systemic, not ocular) + orange glasses
- Weekly: 20 min morning sun on skin + 5 g spirulina
9. Take-Home Soundbites
- “Treat light like food: avoid junk light, feast on full-spectrum.”
- “The Endolight is the farmer’s market of light.”
- “If you biohack sleep, sauna, cold plunge — but ignore light — you’re missing 50 % of the puzzle.”
