Have you heard of blue light? Many people haven’t, but if you’re reading this blog, you’re probably getting a full dose of it right now, from an electronic device that emits blue light. If you spend more than 5 hours a day in front of a computer screen or monitor, this blue light could be damaging to your health, your cells, and even your DNA.
What is blue light?
Blue light is a high-energy, short wavelength of visible light. The shorter a wavelength, the more energy it transmits, and the more damage it can do to your health, skin, and eyes. UV rays from the sun are short wave rays, while blue light is slightly longer than UV rays, is visible, and is just as, if not, more damaging, penetrating all the way to your mitochondria and cellular levels.
Where does blue light come from?
Blue light is everywhere, and the blue light spectrum and electromagnetic fields (EMFs) bombards your cells with different forms of radiation. Sunlight emits blue light, but so do light bulbs, computer screens, smartphones, LED TVs and other electronic screen-based devices. With the increase in screen time, remote working conditions, and apps, blue light exposure is increasing, and can have long-term effects to our health. artificial blue light…and considering how much time we spend on our devices, this exposure can add up.
How does blue light harm your health?
Extended exposure to blue light can negatively affect your health in numerous ways.
Side effects and damage caused by blue light:
- Advanced Aging and Skin Damage: Extended blue light exposure can destroy healthy collagen in your skin and increase the appearance of wrinkles, sagging skin and premature aging.1-3
- Neurological Effects: Blue light exposure over time is shown to increase your hyper-sensitivity to stress, cause brain fog and fatigue, disrupt sleep, and other impacts.5
- Cellular Abnormalities: Blue light , fuels oxidative stress and can cause DNA damage that can lead to cellular abnormalities and cause inflammation, with risks to long-term health.4
- Vision loss: High frequency blue light over time can trigger vision loss and long-term eye problems.5
- Sleep Problems: Blue light can contribute to poor sleep, sleep disruption and sleep disorders, by blocking your body’s natural melatonin production.6
- Low Energy: Blue light raises levels of cortisol and adrenalin and can contribute to energy crashes.
Blue Light Blocking and Protection
With natural ingredients and antioxidants, you can neutralize the damage done by blue light, and keep cells, tissues and even your DNA healthy.
Blue Light Radiation & EMF Defense Supplements
Inner nourishment of the skin helps it repair from radiation and blue light damage. Natural, powerful antioxidants, and supplements are shown to help defend against radiation and blue light, and increase recovery time if you do get exposure to cell threats. Studies show that nutritional antioxidants and ingredients like green tea extract, alpha lipoic acid, and functional mushrooms can provide the essential support you need to keep skin and cells healthy and safe from blue light damage.
