Only over 100 years ago, human beings have evolved to thrive in three types of light: the sun, the moon and fire. In 1893 our life all changed. Thomas Edison established the first commercial electric company, we began to see how we could use non native electromagnetic frequencies (EMF’s) for modern life. Fast forward today, all our modern light-emitting fixtures and appliances, every digital devices we own radiate high intensity blue wavelength light. As much as we all love and depend on artificial lighting to allow us to operate after dark, this artificial high intensity blue light that illuminates our phones, computers, televisions, homes, cars, streets, and places of work is a powerful nnEMF that is extremely detrimental to our well-being on many levels.
While blue light is a natural stressor on its own, The natural blue light in the full spectrum sunlight is always together with other colours such as purple, ultraviolet, red, and infrared. It is always balanced by the red, in other words, in nature, we never see blue light without the red. In fact, the sun has 42% infrared A (IRA) light all year round, while blue varies everyday. This IRA light is the natural antidote to blue light and runs all the regeneration programs in us. In modern life, the artificial blue light we see everyday today has taken out all the healing frequencies eg red and purple. And we are never designed to see the blue light by itself.
Artificial light at night (ALAN) is extremely detrimental to our health and deadly to our cellular biology.
It suppresses melatonin
Melatonin is activated at night after sensing darkness. Any exposure to blue light after dark (eg. LED lighting and screens) disrupts this process. Melanopsin, the blue light detectors in the eyes and skin signals the body to spike cortisol level because daytime frequencies are detected. This elevated cortisol level suppresses melatonin production causing sleeping problems. Studies show that LED and fluorescent lights suppress 80% melatonin production, and incandescent lights suppress 40%.
It destroys DHA
DHA, a type of Omega 3 fat, has tremendous health benefits, from mental health, brain development, fighting cancers and inflammation, to heart health. It is also critical in cellular signalling, allowing the outside to talk to the inside of our bodies. DHA is abundant in the eyes, where the light is turned into electrical signals in all cell membranes. Blue light destroys DHA. Adrenal fatigue, autoimmunity, and mental illness all link back to a lack of DHA in cell membranes.
It lowers dopamine
Dopamine is one of the neurotransmitters in our brain, famously known as the “feel-good hormone.” which is associated with feelings of euphoria, bliss, motivation, and concentration. Dopamine is made when the eyes and skin are exposed to sun light (ultraviolet and infrared) and cannot be made sufficiently under blue light conditions.
A low dopamine level leads to insufficient synthesis of a chemical called beta-endorphin. a natural opioid, and the only opioid that doesn't cause you addicted to any other opioids. Low level of beta-endorphin forces the body to find other ways to replace dopamine deficiency, drugs, cigarette, alcohol, sex, and social media. That's what addiction fundamentally is.
