In today’s world, we are only heading towards a rise of artificially blue lit environments emitted by devices such as TV’s, smart phones, tablets, LED or fluorescent light.
This is resulting in insomnia and restless sleep, depression and anxiety, eye strain, fatigue, headaches and migraines.
The electromagnetic spectrum
Is blue light always harmful?
Blue light is merely high frequency light ranging from 400-495nm. It makes up to approximately 8% of the natural sunlight, with some variations depending on the time of the day as well as the season. White LED’s and light emitted from tech devices is composed of about 40-50% of blue light depending on the device and the brightness.
Natural Blue Light
Blue light emitted from the sun is crucial to our functioning. It regulates our sleep/wake cycles and triggers our alertness and sharpness. Blue light from the sun is not harmful, because it is balanced with red, infrared, ultraviolet and other colors from the visible spectrum. Any natural degeneration that might happen from high energy blue light is balanced with the regenerative capacity of infrared and red light. When the sun sets, the absence of UV, blue and green light triggers the production of the sleep hormone melatonin, which signals to our brain that it is time to rest and rejuvenate.
Artificial Blue Light
Digital devices and light bulbs peak in 420-460nm blue light and hardly emit any orange, red or infrared. Several studies have shown that light in this range causes cellular degeneration and is detrimental to our health and vision. Getting solely exposed to these emitted frequencies during the day causes headaches, fatigue, and itchy dry eyes. Conversely, getting exposed to artificial blue and green light at night inhibits the natural release of melatonin, the sleep hormone, which tricks our brain into thinking it is still daytime.
What is the body’s internal clock?
Also known as biological or circadian clock, it is a simple yet complex program that has programmed us to eat and sleep at the right time throughout a 24-hour period.
How is The Biological Clock Related to Disease?
Unfortunately, more than ever before, we are suffering from chronic diseases such as diabetes, cardiovascular diseases, Alzheimer and dementia, cancer, arthritis, depression and anxiety. Most of these diseases are an accumulation of the biological clock mismatching with the clock outside. This generally happens when misleading information from our artificial indoor lights contradicts with the light and dark cycles found in nature.
Mitochondria are ‘’electromagnetic’’ in nature, which means that the way they process food and make energy is controlled by LIGHT. Additionally, the most important time for mitochondrial repair is SLEEP, which is when our pineal gland perceives total darkness and produces melatonin, the highest anti-aging and anti-oxidant in nature. This explains why so many people struggle with getting results through diet and exercise, as they do not pay attention to light and sleep.
Science has been investigating the positive correlation between living in mismatch with the biological clock, termed as circadian mismatch, and potential failure in mitochondrial functioning. Failure in producing enough energy for cellular and organ functioning leads to chronic disease. Many doctors in the field of mitochondrial health understand that the root of every disease is in fact mitochondrial in nature.
Exposure to Junk Light Increases the Likelihood of Developing Chronic Disease
These power engines called ‘mitochondria’ need as much darkness as they need light in order to function optimally and perform their job of providing energy to the body. At night, they need sufficient deep sleep to rejuvenate and allow the body’s immunity to prevent diseases and illnesses.
This is becoming more difficult in today’s world as we are only heading towards a rise of artificially blue lit environments and an increased chance of being surrounded by devices such as TV’s, phones, tablets, LED or fluorescent light that emit a great amount of junk light.
If you live in the city, you most likely live in perpetual light, and are in desperate need for darkness. We are seeing more and more cases of restless sleep, fatigue, eyesight issues, depression and anxiety with most people working indoors under such lights.
Science has strongly proven that high frequency blue and green lights have a tremendous effect on our brain and cells, the way we function and feel, and the quality of sleep that we get. These lights suppress melatonin, the sleep hormone, keeping the stress hormone cortisol, elevated. This is problematic as it negatively impacts numerous other pathways such as serotonin and dopamine as well as adrenaline levels.
All this to say that exposure to the right light at the right time of the day is crucial for enabling the mitochondrial engines to rest and function optimally, preventing chronic diseases, and in return, reversing them with the proper alignment of the body’s biological clock and the environment we live in.
