Light Shapes Health

Every Spectrum of Light is Bioactive

Each day, light frequencies either harm or improve the health of your:

  • skin
  • gut
  • sleep
  • eyes
  • hormonal balance
  • brain chemistry
  • weight regulation
  • metabolism

Restorative Light

Believe it or not, healthy light frequencies improve all bodily functions.

Why? Because each spectrum of light — both visible and invisible — causes a cascade of biological activity, even at very low intensity.

The body is designed to receive and detect light — and then respond to it with metabolic and hormonal action.

Every minute of the day and night, even! Photoreceptors in eyes and skin receive light and send signals to the brain, telling it what the light in the environment is doing.

And it’s not just the brain, local tissues respond to environmental and therapeutic light as well.

These effects are not minimal — they’re not slight. They are deep and impactful to your health.

Therefore, environmental and therapeutic light needs to be at the forefront of any health strategy.

Human Vision

& and its limitations

The human eye sees a small slice of the total light spectrum.

The sun produces energy across an extremely broad spectrum. The tiny portion the human eye can see is referred to as visible light.

What about the rest of the spectrum that the human eye cannot detect — the frequencies that are invisible?

Those are still light. The invisible wavelengths are just too small or large to see.

Just smaller than the visible spectrum is the invisible UV spectrum. If UV light were any larger in frequency, it would be blue light, and it would be visible.

Just larger than red light is infrared light — which is also invisible. If infrared waves were any shorter, they’d be red, and we’d be able to see them.

All visible light is perceived as a color by the human brain.

The Visible Spectrum

In physics, every time a frequency doubles, it’s referred to as an octave.

In music, the major scale covers one octave.

Actually, all scales are based on one octave — because each octave simply repeats the notes again in a higher register.

A grand piano has 8 octaves.

By comparison, the electromagnetic spectrum has 81 octaves.

Visible light is only one of these 81 octaves — essentially one major scale on an incredibly large piano.

3 Parts of Light

Think of light this way: as three main parts — all affecting health differently.

  • UV
  • Visible light
  • Infrared

For general thinking about healthy light, ignore the X-rays, gamma rays, microwaves, and radio waves.

Instead, focus on the most important spectrums of light — those which greatly impact health on a daily basis. They are:

  • UV
  • Visible
  • Infrared

Solar Radiation Peaks in the Visible Spectrum

Most life on earth is highly attuned to the visible spectrum.

It’s a narrow spectrum — only one octave — but it accounts for 42% of the sun’s power output.

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

* Wireless technology uses long-wavelength spectrums like radio- and microwaves — which is also very important for health. However, concerns about wireless technology can be grouped into their own separate discussion.

Healing Infrared

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

Infrared is becoming increasingly researched and shown to possess numerous health benefits for the body.

4

INFRARED + RED LIGHT

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

This means that more than 2/3 of sunlight is restorative infrared and red light frequencies.

68% of sunlight is infrared & red.

Photobiomodulation

A scientific term for therapeutic light.

PhotO = LIGHT
Bio = living organisms
ModulatE = TO CHANGE

Light that changes living organisms.

“Photobiomodulation (PBM), also known as low-level laser (or light) therapy (LLLT), has been known for almost 50 years.”

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

Michael Hamblin, PhD — Harvard University
Laserbehandling..jpg
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 found that therapeutic lasers produced verifiable results for pain, inflammation, healing, smoking cessation and even hair regrowth. They tended to assume the important component was the fact that the light was in the form of a laser, a very intense beam of light.

It turned out, however, it wasn’t the laser aspect that provided the healing. By the mid-90s, it was clear that the 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.

Virtually All Wavelengths Have Been Studied. Some Excel at Healing.

The most impressive healing 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 benefits to practically every cell in the body.

Compare:

Red -vs- Infrared

Sharing many similar characteristics for our health, these two frequencies do have a few differences.

Red Light is Visible

If an object looks red, red light is coming from it — and entering the eye.

A red LED emitting red light.

Infrared Light is Invisible

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

An infrared LED appears to be off — even when turned on.

Infrared Means “Beyond Red”

Infrared wavelengths are too long for our eyes to observe.

(UV rays are too short for our eyes to see).

Special Technology Can See Infrared Light

Night-Vision Goggles

These $1,000 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.)

https://en.wikipedia.org/wiki/Thermographic_camera

Amazingly, even though infrared light is invisible, we can sense it in another way:
We actually FEEL it.

How? Invisible infrared light is felt as heat.

After all, heat, essentially, is infrared light.

Humans can see light frequencies — and also feel light frequencies.

What cooks the food? Infrared light.

Light Penetrates Into the Body’s Tissues

All frequencies of light penetrate into the body — but each wavelength penetrates to a very specific depth.

Some frequencies penetrate very deeply, while others barely enter the body at all.

Tissue Penetration Depends on The Wavelength

The longer the wavelength, the deeper 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 Light  

2-3mm

Red Light

5-10mm

Infrared Light

9-27cm

Infrared Rays Penetrate Deepest

All light travels in a straight line, and infrared is no different.

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 criticism of INCANDESCENT BULBS: TOO MUCH WASTED INVISIBLE LIGHT (Heat).

“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 almost no red & infrared.

Fluorescent Bulbs
LED Bulbs

Fluorescent & LED bulbs do save on energy costs.

Modern People Are

Almost Always Indoors

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

— Environmental Protection Agency, 2001

That’s 99% Indoors

15 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 most, artificial lighting is the only lighting.

Most folks get very little sunshine.

As a result…

Infrared & red light are absent in modern life.

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 more waking hours in direct or indirect sunlight.

Humans Have Long Depended on Fire to Survive

Fire is incredibly rich in red & infrared light.

The contrast couldn’t be more stark: Modern people receive far less nourishing red & infrared light from the environment.

Improving Your Light Exposure

“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

It’s Up To YOU

The modern world rarely provides a healthy, restorative, or optimal light environment.

Therefore, it’s up to each of us to pursue the benefits of these restorative wavelengths, ourselves.

When you know the best ways to harness the power of these wavelengths, the benefits can be yours.

What Light Has Done For Me

Red and infrared light has already been a major player in the improved health of thousands of people worldwide.

The trend is certainly rising. Professional athletes are using red light to improve recovery after both exercise and injuries. Hair is being (expensively) regrown at hair clinics with simple red light technology available 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.

I personally utilized red & infrared (infraRED!) light as a foundation of my recovery from hypothyroidism and mold illness. I noticed the light spurred my digestion and metabolism, while improving my circadian rhythm and sleep.

My brain, long sluggish, became more active for hours after exposure to these healing wavelengths of light.

Working with clients as a Board-Certified Health Coach, I’ve seen this light improve thyroid & Hashimotos lab numbers, and increase energy levels and brain function in the elderly. Joint and muscle pain has been relieved in folks of all ages.

It doesn’t take a lot of effort to get proper, restorative therapeutic light. It just takes awareness of the best methods, and time during the week to implement.

Virtually everyone can benefit from proper frequencies of light. In chronic illness and aging, these restorative frequencies will be even more important.

My health came back to me — in large part — because I understood the profound biological effects of light. Without awareness of light, my sleep, digestion, and metabolism would not have recovered like they did.

How are you going to incorporate healthy light into your life?
