Why you should use Night Mode on your computing devices?

Apple recently released the iOS 9.3 beta. And though it doesn’t have too many groundbreaking features, one feature that is making waves is the ‘Night Shift’ mode that changes the color of the screen of your iOS device to put less stress on your eyes and helps to sleep better when you use your iOS device after sunset. Here’s why you should definitely use this feature when it becomes available on your iOS device, and also on every other device you own.

These days, we use a scaringly increasing number of computing devices for a scaringly increasing number of hours every day, from the moment we wake up in the morning to the moment we sleep in the night. So much so, that we look at our screens more than we look at our surroundings. And you know what the biggest difference between looking at the two is? The light and the colors we see.

Most screens emit blue light, primarily. This blue light isn’t bad in itself (blue light is what surrounds us when the sun is in the sky), and it is perfectly healthy to absorb as much of it as you want during the day (the blue light produces histamine in our bodies to help us stay up). But when the sun sets is when things get interesting. The blue light from our surroundings is gone and in ideal conditions, without our dozen or so screens surrounding us, we wouldn’t absorb any. This would lead to creation of melatonin in our bodies (melatonin helps us fall asleep) and we’d enjoy a good night’s sleep. But, with our screens in front of us till the very last minute before we decide to sleep, our eyes absorb the blue light from the screen and make our brain think that it is day, thus, increasing our histamine levels and improving our attention levels and reaction times and in the process, not letting our tired bodies fall asleep.

iOS 9.3 with Night Shift

How iOS’s Night Shift solves the the blue light problem (f.lux has been solving it for quite some time for Windows / OS X and Twilight has been doing it well on Android) is by taking the blue light out of our screens and replacing it with orange light. So, after the sun sets, when we use our iOS device, we’d see an orange hue on the screen. Not only does this help us sleep better, this hue, because of its warmer tones, also prevents cornea burn.

I have been using night mode on the various devices that I use after sunset (my Mac and Mi Pad) and though I’m not sure if the orange hues make me sleep better, I can vouch for the fact that my eyes burn less when I finally close them and try to sleep. That, till the time I use night mode enough to be able to comment on the ‘better sleep’ part, is a definite win for me.

And, the best part is, you don’t need to have an iOS device to protect your eyes and sleep better. Such tools are available on each platform. So, do your eyes a favor and the next time you use a computing device after sunset and enable night mode on it. Your eyes will thank you the next morning through a good night’s sleep.

I’ll be compiling a list of the best night mode tools/apps available for each platform and will be sharing it with you soon. In the meantime, stay tuned for more of all things tech.
