What Is A Junk Light?
Junk light refers to artificial light such as LED, fluorescent coming from the screens of laptops, computers, and smartphones. This artificial light, unlike the sunlight, contains a narrow light spectrum mostly occupied with the blue light and no ultraviolet or infrared rays.
Just like junk food leads to malnourishment, junk light causes mal-illumination. The problem lies in the exposure period and the timing of exposure. Junk light or artificial light can aggressively inhibit the melatonin levels.
Moreover, it gives birth too many other issues such as degeneration of the eye tissues, disturbed sleep-wake cycle (circadian rhythm), which is extremely sensitive to this spectrum of light.
How Your Body Perceives This Junk Light?
Research reveals that there is a sensor in human eyes named melanopsin, which is extremely sensitive to green and blue lights emitted by technological devices. This blue or green light gives a signal to your that it’s too bright outside, so the body doesn’t realize that it’s already night time. This leads to disturbed circadian rhythm, and you end up not getting the required sleep.
The Science Behind The Blue Or Junk Light
Blue light has the highest frequency and shortest wavelength among the visual light spectrum. This means that blue light has the maximum penetrating power. We absorb this light through our eyes and skin. Artificial lights tend to have five times more blue waves as compared to the sunlight. This high exposure to only the blue light and deprivation of infrared and ultraviolet rays causes problems in our bodies. The infrared light is perceived by the body as heat and is essential for mitochondrial function and detoxification.
On the other hand, the ultraviolet rays are used to make endorphins and vitamin D in the body. Endorphin is a natural hormone and associated with a feeling of happiness. Therefore, a lack of endorphin can lead to anxiety and depression. In addition, the light also regulates the release of many other types of hormones, such as cortisol, testosterone, and neurotransmitters like dopamine, melatonin, and serotonin. All these hormones and neurotransmitters are essential for a human body and brain as they determine a person’s mood, motivation, happiness, energy, and health.
The Relation Of Light And Body Functions
Light is the most potent cue that the human body uses to synchronize with the natural biological activities, including; wake up and sleep timings. In today’s digital world, it seems impossible to avoid or eliminate the use of technologies that emit these artificial lights.
We spent hours and hours in front of electronic devices and in our artificially overhead lighted environments. Such exposure to artificial lights for a longer period leads to confuse our body and mind functions.
Recent studies have revealed that overexposure to junk light at the wrong time of day can cause negative effects on your sleep, which in turn disturbs your physical and mental performance.
The disturbed sleep patterns and insufficient sleep become a root cause for many other problems such as; anxiety, insomnia, depression, mood disorders, headaches, eye strain, weak eyesight, and reduced cognitive brain functions. Moreover, the lack of quality sleep also leads to other problems such as diabetes, weight loss and weight gain, heart diseases, and various types of cancer.
How Can You Protect Yourself From The Bombarded Junk Light In Your Surroundings?
Have you ever taken some time to notice how many artificial lights are actually surrounding you at home or throughout your typical workday?
Well! We know that it is shocking to realize that it’s nearly impossible to avoid our exposure to these artificial lights. We all have a nature of work that indulges a major part of our time in front of laptops and computers. In addition, our houses and offices also have these LED or fluorescent lights.
You must be wondering then how can we protect ourselves and prevent all those health concerns associated with junk light. Well! The answer to this question lies in the question itself. Yes! Your eyes are the main source of exposure to this light.
So, what if we add a proactive shielding layer onto our eyes? What about we start wearing protective eyeglasses that are capable of filtering the harmful blue lights emitted by all the electronic gadgets and LED or fluorescent bulbs at our home and offices?
Protective Eye Gear
Science has made our lives far easier than one could ever have imagined. There are now a number of brands that offer protective glasses. This protective gear allows only the healthy amount of the light spectrum to reach your brain and eyes. It helps you stay alert, awake, and productive during your work hours and day time.
Moreover, it prevents headaches and protects your eye muscles from getting weak.
These glasses have a dot mechanism that allows you to completely cover the lights found in the corner of electronic gadgets such as laptops, mobile phones, television, and computer screens. In short, you have to simply place the dot over the light being emitted from gadgets; this will help the green or blue light disappear from your vision. Famous brands are making quiet conscious efforts to comfort both humans and the environment by providing beneficial products in eco friendly boxes.
In conclusion, it’s important that we take care of ourselves and much vital to take care of our environment. We have to live in this environment till death, so it’s essential to present such products in custom packaging boxes.
