When it comes to health, our tech habits are put into the â??microscopeâ? especially when it comes to preserving our unhealthy memory, unhealthy sleep patterns, and impaired vision. As if that weren't enough, more and more research is being done on "blue light," the secret enemy of beauty on digital devices that poses a danger to our skin. If you are one of the many people wondering how this might affect you, read on.
What is "blue light"?
"Blue light" refers to the wavelength of high-energy wavelengths that are on the blue edge of the visible light spectrum. We are exposed to blue light from the sun, however it is also emitted by LED lights, such as those found on our phones, TV screens, laptops, and according to recent research, Australians are spending more than nine hours a day in front of digital cameras that expose them even more to blue light.
Blue light is not necessarily bad when it is emitted at the right wavelength, and can even be used to kill acne and smooth out wrinkle lines. According to skin expert Jocelyn Petroni, blue light infiltrates skin even further than UVA / UVB rays, which we have almost avoided all the time. What this light does is penetrate directly into the skin dermis, causing oxidative stress on the skin, leading to premature aging. Moreover, it can generate free radicals, which damages the natural collagen in our skin. What we are left with are wrinkles, excessive pigmentation and decreased skin elasticity. And if you do not sleep beauty regularly, then you are even more sensitive and exposed to these negative phenomena.
How can we protect ourselves?
Thankfully the beauty industry has responded to our call, with an increase in products aimed at protecting against blue light. Choose products with rich moisturizing, antioxidant formulas that protect and minimize damage from free radicals. A broad-spectrum SPF that protects against UVA and UVB rays is also essential as well as hyaluronic acid to maintain optimal levels of hydration. While it is difficult to admit that we are completely out of technology, we can minimize the damage to some extent. Some smartphones these days have a system called 'night shift' that switches blue to yellow, which is much better for eyes and skin. Blue light filter screen protectors are also a good option, or you can commit to reducing the use of electronic devices, so maybe a digital detox would not be a waste of time ...
