Everything You Need to Know About Fake Light and Health
All living organisms have an internal clock, set by morning sunlight exposure and nighttime darkness
This clock (called a “circadian rhythm”) controls hormones, metabolism, the sleep/wake cycle and all growth and repair
(It is pretty important.)
Artificial light exposure after sunset tells the brain that the sun is rising, preventing melatonin secretion
This damages sleep and repair quality, accelerating aging and disease generation over time.
Our glasses block all frequencies of light that suppress melatonin
– Making it easier to fall asleep
– Improving sleep and repair quality
– Making you more well-rested and energized in the morning
– Protecting mitochondrial DNA damage, slowing aging and preventing disease generation over time
– Improving mood, energy, and overall quality of health, vibrancy, and life

What is Blue Light and Why Can it be Harmful?
Life is a biophysical phenomenon that captures energy from its environment, then uses it to create structure and carry out functions.
Life is constantly sculpted by this energy acting on raw materials in the environment.
Every twenty-four hours on Earth, life experiences an environment of light and solar energy, of dark and magetic field energy.
Nature sculpted a twenty-four hour clock into the first organisms so they could maximize the use of solar energy during the day, and regeneration and growth and night.
She sculpted this clock to be set every day by the sun’s first presence and absence: sunrise and sunset, dawn and dusk.
She sculpted receptors for the sun’s signals, and she made them sensitive to Blue Light frequencies, 400-485 nm in the language of modern man.
She chose blue because it very energetic and always present in the sun’s spectrum, so it could not be missed as long as life lived in nature.
For 4 billion years, nature’s children evolved like so. Their evolution through changing environments was so effective and so beautiful.
At one point, nature brought life to an environment richer in energy and in her most effective energy conducting materials than ever before. Life was again sculpted by this environmental shift, as it had been since the beginning.
These allowed life to innovate the most complex structures ever known, creating a new type of life form, markedly different from all the others in one massive way. Life was never to be the same again.
After 4 billion years, life would no longer be sculpted its environment. Life had developed so great a capacity for analyzing and computing that rather than change himself to suit the environment, he would survive by changing the environment to suit himself. Man was born.
With this method, man became the first species to conquer every climate on Earth.
When it became more profitable for some men, they did away with the sun’s clock, beginning to live and work on a set schedule even throughout the changing seasons. This was the Industrial Revolution.
For the first time in 4 billion years, life no longer lived in nature.
She had given man the greatest gift, but man had not been so wise, so he began to use the gift in a way that harms him.
We use artificial lighting to artificially extend our day. Today, the most prominent frequency in artificial lighting is Blue Light. It keeps us awake, but it does not provide us with the other frequencies that this wakeful state requires, namely Ultraviolet (UV) and Infrared (IR). This leads to a “theft” of energy from ourselves; present wakefulness at the expense of future biologic time.
No matter what we do, a diurnal animal (opposite of nocturnal) is designed to be awake while the earth is exposed to solar light, also known as day, and asleep, repairing and regenerating, while this light is absent.
Artificial blue light frequencies suppress nature’s elixir for sleep and repair, known to man as melatonin. Melatonin repairs the thousands of tiny bacterial engines in every single one of man’s cells, known to man as Mitochondria.
Some of the most curious, brilliant, and honest men and women of their kind have sought to discover nature’s deepest secrets by examining closely her sculptures and how they change and interact.
These men and women, known to man as “scientists” have discovered that life is only alive because of these thousands of tiny engines in every cell, and that if these engines decrease in function, the body can no longer carry out its more complex functions, leading to dysfunction. Man calls dysfunction “disease”.
These “Mitochondria” don’t just work for free, however. They require their rest and repair every single night, which is controlled completely by Melatonin.
Our energy levels, sleep quality, physical appearance, metabolism, fat burning, mood and everything else is directly dependant upon their function. So when we expose ourselves to fake light at night, a simple act become deadly. We tell our body that it is day. This suppresses melatonin levels, completely destroying the sole process that makes us younger every night, therefore massively accelerating aging and disease generation.
The first symptoms are trouble falling asleep, or being tired upon waking. The next is being tired and moody during the day. As the mitochondrial assault continues with artificial light exposure each night, their function declines, so our metabolism slows down and we begin to lost our ability to burn fat. A strong desire to eat carbohydrates/sugars constantly, and getting “hangry” when without carbohydrates for more than a few hours, accompanies this situation. Being “stressed” is the most prominent effect of this situation, and things like acne or easily being injured come along, too. Quite literally, lowered mitochondrial functions means less energy, meaning that we are actually “less alive”. We have less light and energy in our brain, so our neurotransmitters’ function declines and we become depressed. Those who continue this assault at full force for the longest end up with autoimmune diseases and cancer. Those who are born to someone living the assault may have autism or childhood cancer.
Dr. Douglas Wallace of the Children’s Hospital of Philadelphia has proven this across 40 years of research, and is now winning prestigious awards for his tremendous findings. They provide man with an understanding unlike ever before: that his most common diseases are caused by decreases in energy. These decreases in energy are caused by damaged mitochondrial function, which is caused by damaged mitochondrial DNA. The ultimate cause is man’s use of artificial light to artificially extend daytime, destroying his melatonin levels and mitochondrial repair.

Blue light has a dark side
Exposure to blue light at night, emitted by electronics and energy-efficient lightbulbs, harmful to your health.
Until the advent of artificial lighting, the sun was the major source of lighting, and people spent their evenings in (relative) darkness. Now, in much of the world, evenings are illuminated, and we take our easy access to all those lumens pretty much for granted.
But we may be paying a price for basking in all that light. At night, light throws the body’s biological clock—the circadian rhythm—out of whack. Sleep suffers. Worse, research shows that it may contribute to the causation of cancer, diabetes, heart disease, and obesity.
But not all colors of light have the same effect. Blue wavelengths—which are beneficial during daylight hours because they boost attention, reaction times, and mood—seem to be the most disruptive at night. And the proliferation of electronics with screens, as well as energy-efficient lighting, is increasing our exposure to blue wavelengths, especially after sundown.
Daily rhythms influenced by light
Everyone has slightly different circadian rhythms, but the average length is 24 and one-quarter hours. The circadian rhythm of people who stay up late is slightly longer, while the rhythms of earlier birds fall short of 24 hours. Dr. Charles Czeisler of Harvard Medical School showed, in 1981, that daylight keeps a person’s internal clock aligned with the environment.
The health risks of nighttime light
Study after study has linked working the night shift and exposure to light at night to several types of cancer (breast, prostate), diabetes, heart disease, and obesity. It’s not exactly clear why nighttime light exposure seems to be so bad for us. But we do know that exposure to light suppresses the secretion of melatonin, a hormone that influences circadian rhythms, and there’s some experimental evidence (it’s very preliminary) that lower melatonin levels might explain the association with cancer.
A Harvard study shed a little bit of light on the possible connection to diabetes and possibly obesity. The researchers put 10 people on a schedule that gradually shifted the timing of their circadian rhythms. Their blood sugar levels increased, throwing them into a prediabetic state, and levels of leptin, a hormone that leaves people feeling full after a meal, went down.
Even dim light can interfere with a person’s circadian rhythm and melatonin secretion. A mere eight lux—a level of brightness exceeded by most table lamps and about twice that of a night light—has an effect, notes Stephen Lockley, a Harvard sleep researcher. Light at night is part of the reason so many people don’t get enough sleep, says Lockley, and researchers have linked short sleep to increased risk for depression, as well as diabetes and cardiovascular problems.
The power of the blues
While light of any kind can suppress the secretion of melatonin, blue light at night does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours).
In another study of blue light, researchers at the University of Toronto compared the melatonin levels of people exposed to bright indoor light who were wearing blue-light–blocking goggles to people exposed to regular dim light without wearing goggles. The fact that the levels of the hormone were about the same in the two groups strengthens the hypothesis that blue light is a potent suppressor of melatonin. It also suggests that shift workers and night owls could perhaps protect themselves if they wore eyewear that blocks blue light. Inexpensive sunglasses with orange-tinted lenses block blue light, but they also block other colors, so they’re not suitable for use indoors at night. Glasses that block out only blue light can cost up to $80.
If blue light does have adverse health effects, then environmental concerns, and the quest for energy-efficient lighting, could be at odds with personal health. Those curlicue compact fluorescent lightbulbs and LED lights are much more energy-efficient than the old-fashioned incandescent lightbulbs we grew up with. But they also tend to produce more blue light.
The physics of fluorescent lights can’t be changed, but coatings inside the bulbs can be so they produce a warmer, less blue light. LED lights are more efficient than fluorescent lights, but they also produce a fair amount of light in the blue spectrum. Richard Hansler, a light researcher at John Carroll University in Cleveland, notes that ordinary incandescent lights also produce some blue light, although less than most fluorescent lightbulbs.
What you can do
- Use dim red lights for night lights. Red light has the least power to shift circadian rhythm and suppress melatonin.
- Avoid looking at bright screens beginning two to three hours before bed.
- If you work a night shift or use a lot of electronic devices at night, consider wearing blue-blocking glasses or installing an app that filters the blue/green wavelength at night.
- Expose yourself to lots of bright light during the day, which will boost your ability to sleep at night, as well as your mood and alertness during daylight.
