What Is “Blue Light” and Why Is It Harmful?
By now, most of you have probably heard that blue light from your devices may be affecting your sleep. If you are like most people, you fall asleep reading your tablet or articles on your phone, streaming TV apps or simply browsing the internet. The blue light that your device’s screen emits, stimulates your brain and fools it into thinking that it is daytime. Researchers have discovered that this is eating away at your sleep. In an article from Business Insider, “Studies have shown that being exposed to the blue-and-white light given off by phones, laptops, and other electronic gadgets at night prevents our brains from releasing melatonin, a hormone that tells our bodies it’s nighttime.” Thus, prolonging the time it takes to fall asleep. Researchers believe that after several years of exposure to blue light, your body’s internal clock may suffer.
Studies suggest that you do not use any devices for roughly an hour before bedtime to prevent this. There are also options available on your devices under the display settings to adjust the screen’s temperature to a warmer color and filtering out blue light.
