CHICAGo --It's a fact of life: Some of the things that bring you joy can wind up being bad for you. and no, we're not talking about Blue Bell.
We're talking about blue light. That's the wavelength of light that's produced by your precious smartphone and other electronic devices.
Blue light is naturally produced from sunlight during the day. It helps us stay alert and pay attention, but it becomes an issue during those late night phone binging sessions when you're supposed to be getting ready to sleep. The light can disrupt your sleep pattern by suppressing the hormone melatonin, which means it's tricking your brain into believing it's actually daytime.
But melatonin isn't just for making us sleepy. It's also an antioxidant that plays a role in slowing the progression of cancer, diabetes, and obesity. Luckily, there are apps available that filter out blue light so you can have your late-night phone and tablet sessions in peace.
Plus, many doctors suggest taking a break from devices that emit blue light every now and then to avoid eye strain and long-term eye trouble. In fact, there are now even special lenses that protect your eyes from blue light.
So, the science is in. Keep track of how often you use your devices or you could end up feeling blue.
