Sleep Disruption Because of Blue Light

Everyone has done it: You’re lying in bed, scrolling through a newsfeed or laughing at a funny picture online. After a minute, or an hour, you turn off your screen, roll over, and close your eyes. You take a deep breath, and feel your whole body relax. An hour passes, then two, then three, as you toss and turn in your nice warm, dark room. Midnight comes, but sleep doesn’t. There are a dozen causes that could lead to insomnia, everything from caffeine to stress. As technology becomes more and more ubiquitous through our lives, researchers are looking into the effects of our computer usage on our sleeping patterns. The news isn’t good: Blue light emitted by our electronics is destroying our circadian rhythm. A lack of circadian rhythm effects our sleep cycle, our health, and how we can fix it.

Our bodies are biologically trained to sense days and nights. Before we had artificial lights, we needed to know when to be productive, when we could see, and when it was time for rest. In the age of artificial lights, and artificial stimulants such as caffeine, we choose to ignore our sense of day and night. Our bodies have not. Somewhere in the DNA, there is still an understanding that “Daytime is for working, nighttime is for sleeping.” Blue light triggers a sense that it is still daytime, and it takes a while for the body respond. Just because you’ve turned off your computer for the night doesn’t mean your body understands it’s time to sleep. Melatonin is a natural hormone that is produced in the pituitary gland, and it regulates sleep. If your circadian rhythm is off track, your body doesn’t know when to produce melatonin, resulting in chronic insomnia. In order to block blue light, shades or glasses are needed. EXYRA  has produced the next generation of glasses for that purpose.

Insomnia effects tens of millions of people in the United States alone. There are many artificial supplements that can help regulate melatonin production and sleep cycles. If you are not happy about taking pills just to get to sleep, some behavior modification can help reset your circadian rhythm, and get your sleep cycle back on track. Purchasing glasses with a blue light filter will screen out the blue light from your computer. The easiest thing you can do to increase your restfulness at night is to turn off your screens at least one hour before bed. This will give your brain a chance to reset a little, and produce melatonin naturally.

The 21st century says never to rest, never to turn off, never to check out. You cannot be the best version of you if you don’t check out once and a while. Don’t be afraid to turn off your computer before bed. If you really cannot afford to, EXYRA has developed glasses that will reduce eyestrain and improve your work life.
