Beyond Red Light: The New Era of Whole-Blood Photobiomodulation
In an interesting interview, Sayer Ji discusses 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.

Summary of the Interview
1. Introduction
Light is a biological nutrient that powers ATP, repairs mitochondria, and regulates every system. Modern junk lighting + indoor life = widespread light-deficiency disease. A solution: 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, increases ATP, decreases inflammation, aids repair.
- Each colour has a job:
- Blue (daytime): increases nitric oxide, alertness, fights acne
- Green/Yellow: increases blood flow, mood, collagen
- Orange: prefrontal cortex boost, safe at night
- Red/Near-IR: deepest penetration, aids in pain relief, muscle and bone health
- 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 tuberculosis
- 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)
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
- Increase SpO₂ (oxygen saturation) within minutes
- Increase HRV (stress resilience)
- Decrease 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)
- 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 + 5g 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 pay attention to your food and daily habits – but ignore light – you’re missing 50 % of the health puzzle.”
