What is Blue Light?
Blue light is the component of natural sunlight that sets our body’s inner clock (called a circadian rhythm). In this way, it controls our sleep/wake cycle, production of key hormones and neurotransmitters, metabolic activity, and, as a result, has an effect on virtually every process in the body.
How can blue light be harmful?
Blue light can become harmful in a few ways. Modern, man-made light sources have been able to isolate certain wavelengths of light, and utilize blue wavelengths to stimulate the brain and body for activity, effectively “force-stressing” people into more work and productivity, by affecting our hormones and neurotransmitters—in the workplace or at school, for example.
Near-infrared light, which is always present in large quantities in sunlight, naturally counter-balances the damaging effects of high-energy blue light. Modern light sources, in order to be more “energy efficient” have completely eliminated near-infrared light, because it is believed to be “wasted energy”.
Therefore, modern light sources lack near-infrared light, causing the blue light that they emit to be very detrimental to the health of our eyes, cells, brain, and body as whole.
During the day, chronic exposure to blue light from man-made sources (modern lighting appliances and screen devices) can cause eyestrain, headaches, and fatigue. Over time, this exposure can lead to retinal damage
At night, blue light tricks the brain into thinking that it is daytime, when it is not. It causes the brain to halt the natural secretion of melatonin, which is the hormone that prepares our brain and body for sleep, when light (especially blue light) is no longer present in the environment.
Melatonin is the body’s most essential antioxidant, anti-aging, and anti-cancer hormone. Disruption of melatonin will make it difficult to relax naturally in the evening, and to fall asleep.
So, people will find that they need external substances like alcohol, drugs, and/or pharmaceuticals, just to be able to relax and fall asleep. Sleep quality will be impaired, and you can become restless, tossing and turning, waking up during the night, and so on. As a result, you will not wake up feeling refreshed, nor have the energy that you need to be maximally successful and productive in your day.
By simply blocking this blue light, we can prevent all of these issues, during the day, and in the evening.
