How Blue Light Affects Your Skin (& What to Do About It)
Blue light (AKA high energy visible light - HEVL) is all around us. These days, we use our computers for everything: we use them to take notes in class, do research for term papers, take tests online, and for anyone with a desk job, that's about 35 hours per week in front of a computer. If we aren't on our computer, we're catching up on our favorite TV shows or scrolling through endless streams of social media content to keep up with friends, family, and our favorite celebs.
There have been many reports, news articles, and opinion pieces regarding how screen time affects our eyes, attention span, brain development, sleep quality, emotional health, and more. But what about how this type of light affects our skin?
Several studies have suggested that prolonged exposure to blue light can increase hyperpigmentation (dark spots on the skin, also called sun spots) as well as wrinkles and fine lines. 😱
While the research regarding blue light and skin isn't overwhelming, it's worth paying attention to, especially considering the dozens of other negative side affects of too much screen time. Do your skin (and body) a favor by following these tips to reduce blue light in your life ... just to be on the safe side:
Less screen time. This is a no-brainer. If you want to reduce your blue light exposure, spend considerably less time on devices that emit blue light. If that means use an app-blocking app on your phone to limit your most addictive apps, go for it.
Enable "blue light shield" mode. This mode (also called "comfort mode," "reading mode," or "night mode") comes standard on most new phones, laptops, and tablets. Find it in your settings, turn it on, and forget about it.
Buy a blue light filter. Many companies make physical blue light filters for your plethora of devices. They aren't very expensive, so it's a worthy investment.
A constant barrage of blue light may be causing long-term damage to your skin. Play it safe and limit exposure early to keep your skin at its best!
