Part 1: Why Play Cell Phones at Night Bad for Us?

Blue light, which is the light on the spectrum that makes our computer, tablet, and phone screens look so crisp and bright, is great during the day because it mimics a bright morning. Blue wavelengths wake us up, boost our attention, and let us know it's time to start the day.

At night, blue light is less desirable because that's the time when our bodies should be getting ready to wind down for sleep. Studies have shown that looking at a bright blue screen during the evening hours can confuse the body's biological clock and disrupt our natural circadian rhythm (the ~24-hour light and dark schedule everyone runs on) by suppressing melatonin production, making it harder to fall asleep. All light disrupts the circadian rhythm, but blue light has been proven to be the most disruptive.

That is to say, your iPhone and Android device might be keeping you up at night. According to scientists, a screen with a darker and yellower color is conducive to sleeping. We will show you two solutions about how to reduce blue light below respectively on iPhone and Android.

As a matter of fact, Android users have plenty of options, for there are a number of Apps in Android market developed to shift to Night Mode. Here I recommend Twilight, a screen dimmer for healthy sleep.

When the screen is still too bright to accept under the least brightness, Twilight will relax your eyes with a sight protection blue light filter, which is good for those prone to eye strain or preferable to stay up at night, reducing display’s blue light emission.
