How LED Light Is Making You Sick

• LEDs emit nonanalog light that typically has excessive blue frequencies. Regular exposure, especially after sunset, will contribute to worsening of sleep and an increase in disease
•  
• When using LEDs, you might end up with increased cellular damage and decreased repair and regeneration
•  
• You have cells in your retina responsible for producing melatonin, which regenerates the retina during the night. If you use LED lights after sunset, you reduce the regenerative and restoring capacities of your eyes, raising your risk for macular degeneration, a leading cause of blindness
•  
• LED light can exacerbate chronic disease of all kinds by promoting mitochondrial dysfunction and suppressing energy production in your cells
•  
• LED light, including that from electronic screens, suppresses melatonin production, thereby disrupting sleep, which also has far-reaching health consequences

Danger No. 1: LED Lighting Deteriorates Vision

As mentioned, virtually all LED lighting bulbs have no near-infrared frequencies to balance their blue light frequencies. The near-infrared frequencies are especially valuable for healing and affect your health in a number of important ways. In your eyes, near-infrared helps priming your retinal cells for repair and regeneration.

In addition, LEDs emit an excess of digital blue light, that in combination with a deficiency of the near infrared frequencies, generates ROS. Taken together, this explains why LEDs are so harmful for your eyes in particular.

You probably know that blue light in the evening reduces your melatonin production in your pineal gland. But you also have cells in your retina that are responsible for producing melatonin in order to help regenerate your retina during the night.

If you use LED lights after sunset, you reduce the regenerative and restoring capacities of your eyes. Needless to say, with less regeneration you end up with degeneration. In this case, the degeneration can lead to age-related macular degeneration, which is the primary cause of blindness among the elderly.

Lack of sunlight exposure during the day has also been implicated in the massive rise in myopia (nearsightedness).¹ Sunlight releases dopamine in your retina, slowing the growth of your eye and therefore possibly slowing the elongation of the eye and changes to your sight.²

Blue light also reduces your production of melatonin which, beyond impeding sleep, also increases your risk of insulin resistance, which also raises your risk of myopia.³

Danger No. 2: LED Light Exacerbates Chronic Disease Through Mitochondrial Dysfunction and Suppressed Energy Production

Importantly, LED light affects your mitochondrial function and may exacerbate health problems rooted in mitochondrial dysfunction, including metabolic disorder and cancer.

Chromophores are molecules that absorb light. There’s an optical tissue window ranging from 600 to 1,400 nanometers, which means it is almost completely covered by the near-infrared- part of the light spectrum. This optical tissue window allows the radiation to penetrate an inch or more into bodily tissues.

Chromophores are found in your mitochondria and in activated water molecules. In your mitochondria, there’s also a specific molecule called cytochrome c oxidase that is involved in the energy production within the mitochondria. Adenosine triphosphate (ATP) — cellular energy — is the end product.

ATP is the fuel your cells need for all of their varied functions, including ion transport, synthesizing and metabolism. Your body produces your body weight in ATP every day. And, while you can survive for several minutes without oxygen, were all ATP production to suddenly stop, you’d die within 15 seconds. This is why lighting is so important.

Light is a sorely misunderstood and overlooked part of the equation for biological energy production, specifically at the mitochondrial ATP level. Since the cytochrome c oxidase is responsible for an increased production of ATP, the cell has a better supply of energy, which allows it to perform better, and this is true no matter where the cell resides.

This means liver cells with more ATP will be able to detoxify your body more efficiently; fibroblasts in your skin will be able to synthesize more collagen fibers and so on, because ATP is crucial for all cellular functions.

The key take-home message here is that your body’s energy production involves not just food intake. You also need exposure to certain wavelengths of light in order for your metabolism to function optimally. This is yet another reason why sun exposure is so vitally important for optimal health, and why LED light bulbs are best avoided.

Danger No. 3: LED Light Impedes Your Sleep

LED light, including that from electronic screens, also suppresses melatonin production, thereby disrupting sleep, and this too can have far-reaching consequences for your health. Light-sensitive cells in your eyes track blue light, which in turn triggers different processes in your suprachiasmatic nucleus, a small region in your brain’s hypothalamus.

Among them is relaying to your pineal gland the news that when there is a lot of blue light, the production of melatonin should stop to facilitate wakefulness. Under normal conditions, as the sun sets and blue light decreases, production of melatonin increases, which helps you fall asleep.

However, if you’re exposed to unopposed blue enriched LED light, especially if it is bright, in the evening this sequence is interrupted, resulting in sleep problems. Indeed, research⁴ confirms that “blue light from LEDs elicits a dose-dependent suppression of melatonin in humans.”

Looking at a tablet for even two hours in the evening is enough to suppress your body’s natural nighttime rise of this hormone,⁵ and research^6,7 shows using an electronic device within one hour of bedtime can delay falling asleep for more than an hour.

Another study⁸ that compared melatonin profiles in individuals exposed to standard room light (<200 lux) versus dim light (<3 lux) found exposure to room light before bedtime shortened the time of elevated melatonin levels by about 90 minutes.

That means it may take you an extra hour and a half before you’re sleepy enough to fall asleep once you’re in bed. Combine room light and electronic displays right before bed and it’s easy to see how sleep may remain elusive for hours on end.

Most of us enjoy watching TV in the evening as a form of relaxation before bed. I certainly do and watch many great Netflix documentaries. The key here is most TVs can’t filter out blue light, but if you use a computer monitor as your TV screen you can use Iris; simply install the blue light filtering software on your computer. This will allow you to safely watch TV at night without suppressing your melatonin.

For Optimal Health, Address Your Daily Light Exposure

The good news is that you can remedy all of these health dangers by modifying your light environment and resynchronizing your body to the natural cycles of light and dark. Here are four key considerations:
