Light Shapes Health

Each Wavelength Of Light Affects The Entire Body

Unbalanced Light

Every day, unhealthy light interferes with brain chemistry, harms the skin and eyes, elevates the hormones of stress, and directly disrupts sleep.

Restorative Light

By contrast, healthy light frequencies balance the hormones, encourage sleep, improve mood, increase immunity, and boost thyroid function.

Light needs to be at the forefront of a health strategy.

Where the light does not enter — so enters the doctor.

– ancient proverb


How To Think About Light

The human eye sees a small fraction of the light spectrum.

The sun produces energy across a wide spectrum. The tiny portion the human eye can see is referred to as light.

The rest of the spectrum the human eye cannot detect? It’s still light. The invisible wavelengths are just too small or large to see.

All visible light is perceived as a color (ROY G. BIV) by the human brain.

The Visible Spectrum

Every time a frequency doubles, it’s referred to as an octave. The major scale covers one octave.

A grand piano has 8 octaves.

By comparison, the electromagnetic spectrum has 81 octaves. Visible light is only one of these 81 octaves.

Visible light is essentially one major scale on an incredibly large piano.

  • White light is actually a combination of colors, but blue is especially critical for creating the appearance of white light.
  • ROY G. BIV’ — The acronym named by Isaac Newton, is completely arbitrary. Newton wanted seven primary colors — so he included indigo, which is halfway between blue and purple.
  • UV light makes whites look whiter to the human eye.


In Terms Of Health,

Think Of Light As 3 Parts

  • UV
  • Visible light
  • Infrared
Solar Radiation Peaks In The Visible Spectrum

A significant portion of sunlight’s power radiates in visible wavelengths: 42% is in the visible octave.


Sunlight Is Mostly Infrared

A majority (54%) of sunlight is invisible infrared light.

A majority of the sun’s energy is restorative infrared light.


Infrared + red light


Infrared’s Partner: Red Light

When the sun’s red and infrared output are added together, they make up 68% of total sunshine.

More than 2/3 of sunlight is restorative infrared and red light frequencies.

Key fact: 68% of sunlight is infrared & red.


Red & Infrared Light

…have incredible health benefits

The NASA ‘HEALS’ Light Uses Red & Infrared Light

“The innovation of the NASA HEALS technology provides the equivalent light energy of 12 suns from each of the 288 LED chips.”




InfraRED Light Is Incredibly Beneficial


Insulin Resistance & Obesity

Cardiovascular Health

Joint Pain & Inflammation


Chronic Pain Reduction (& Arthritis)

Cognition & Mood

“Photobiomodulation (PBM), also known as low-level laser (or light) therapy (LLLT), has been known for almost 50 years but still has not gained widespread acceptance, largely due to uncertainty about the molecular, cellular, and tissular mechanisms of action.”

In recent years, much knowledge has been gained in this area.

Michael Hamblin, PhD — Harvard University
The term “photobiomodulation” was coined in the mid-90s and in 2015 it was added to the National Library of Medicine official terminology.

For decades, researchers thought therapeutic lasers — which produced significant results for pain, inflammation, healing, smoking cessation and even hair regrowth — were effective because they were using lasers.

However, it wasn’t the laser aspect that provided the healing effects. By the mid-90s, it was clear that the (red & infrared) wavelengths of light themselves — not the laser aspect — were responsible for the successful findings.

Thus, the study of “low-level laser therapy” became the study of “photobiomodulation” (the study of how light affects changes in the body).

LEDs became the technology of choice because they can deliver specific wavelengths to bodily tissues.

LEDs can provide very specific wavelengths. PICTURED: A cheap 660nm red LED from Amazon. Link:

Virtually Every Wavelength Has Been Studied

The most impressive results come from the frequencies found in visible red light (around 660nm) and “near infrared” frequencies (around 880nm).

ALL wavelengths of red & infrared light provide deep benefits.


Red & Infrared: A Comparison

Red Light Is Visible

If an object appears red, red light is entering the eye.

Infrared Light Is Invisible

The human eye cannot see infrared light. The wavelengths are too long — just longer than red light.

The light from these infrared LED bulbs will be invisible.

Infrared Means “Beyond Red”

Infrared wavelengths are too long for our eyes to observe.

Special Technology Can See Infrared Light

Night-Vision Goggles

These $8,000 night-vision goggles detect “invisible” infrared light to “see” in the dark.

Security Cameras

Night-vision surveillance cameras “see” infrared light. This camera even has Infrared LED’s to shine on potential criminals.

“Heat Signature” = Infrared Light

Image result for heat signature night vision
The “night-vision” camera can see this dog at night.

(More infrared wavelengths are coming out of the dog’s eyes and mouth — fur absorbs infrared light.)

Infrared light is invisible, but we can actually FEEL it.

Infrared light is felt as heat.


Heat is infrared light.


Humans can see light — and also feel light.

What cooks the burgers? Infrared light.


All Light Penetrates Into The Body

Tissue Penetration Depends On The Wavelength

The longer the wavelength, the deeper the light penetrates into tissues.

Blue light barely penetrates at all, just 2-4 millimeters.

Red light penetrates several inches into the flesh.

Infrared can penetrate deeply into the body, nourishing even the inner organs.

Penetration Depth In Human Tissue

(Blue vs Red vs Infrared)

Infrared Rays Penetrate Deepest

Infrared light travels in a straight line, just as all light does.

This deep penetration into the body allows infrared therapy to affect all tissues and organs in the body.


The Incandescent Light Bulb

extremely rich in red & infrared.

90% of incandescent bulbs’ output is infrared light.

Thomas Edison invented the light bulb, but it mostly produced invisible infrared.

The knock against incandescent bulbs: Too much “wasted” invisible light.

“An incandescent bulb is a better heater than light bulb.”

–Industry scientists circa 2010

Throughout the 2010s, countries began banning the sale of incandescents to save energy costs and burn fewer fossil fuels.


Modern Lighting

Modern lighting provides virtually ZERO red & infrared.

Fluorescent Bulbs
LED Bulbs

Fluorescent & LED Bulbs save on energy costs.

——-> By removing the red & infrared light.


Modern People, Always Inside

The average American spends 93% of their life indoors, with another 6% in automobiles.

— Environmental Protection Agency, 2001

99% Indoors

Fifteen minutes. That’s how long the average American spends outside each day.

What are the health implications of spending nearly all time indoors? There’s a serious air quality threat (on average, indoor pollutants are 5 times worse than outdoor air, but are often 100 times worse), for sure. But there’s a lack of healthy spectrums of light.

What are the missing frequencies in modern life? Red and infrared.

For many, artificial lighting is the only lighting.

Most people get very, very little sunshine.

Infrared & red light are absent in modern life.

93% of time spent indoors + 6% in automobiles = 99% of life spent indoors, (on average).

The Stats For The Average American

93% indoors
+ 6% in automobiles 
= 99% of life spent indoors.

On average, 99% of modern life is spent indoors.

Humans Throughout History?

Throughout history, humans spent waking hours in direct or indirect sunlight.

And Near Fire…

Fire is an INCREDIBLE source of red & infrared light.

Most modern people receive very little red & infrared light.

“Penetrating red light is possibly the fundamental anti-stress factor for all organisms. The chronic deficiency of such light is, I think, the best explanation for the deterioration which occurs with aging.”

— Ray Peat, PhD


Improve Your Light Exposure

It’s Up To Us

The modern world does not facilitate a healthy, restorative, or optimal light environment. Therefore, each person must make a. decision to personally ensure they receive — and enjoy — the benefits of exposure to these restorative wavelengths.

However, we need to know the best ways to harness these wavelengths.

What Light Can Do

Red and infrared light has been a major player in the health of thousands of people worldwide. The trend is rising. Professional athletes are using red light to improve recovery after both exercise and injuries. Hair is being (expensively) regrown with simple technology avilable on Amazon.

Light therapy is resulting in better sleep, energy levels, pain perception, workouts, post-exercise and post-surgery recovery, mood, digestion, gut health, and better skin.

To know how light can improve health — and harm it — needs to be at the forefront of any health strategy.
