Ever notice how people texting at night have that eerie blue glow?
Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen?
During the day, computer screens look good—they’re designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn’t be looking at the sun.
Not only will it make the screen easier on the eyes, but it could even help you sleep!
Like in Effect of Color Temperature of Light Sources on Slow-wave Sleep:
Seven healthy males were exposed to the light sources of different color temperatures (3000 K, 5000 K and 6700 K) for 6.5 h before sleep. Subjects slept on a bed in near darkness after extinguishing the light. In the early phase of the sleep period, the amount of stage-4 sleep was significantly shortened under the higher color temperature of 6700 K compared with the lower color temperature of 3000 K.
It looks like staring at a brightly lit device has a tendency to keep us up longer than necessary; read the actually study here.
Oh! There is also an app for the iPhone and iPad; they better make one for Android soon, my eyes hurt looking at my phone so late.
