The basic idea of both Night Light (Android) and Night Shift (iOS) is that splashing our faces with bright light in the wee hours of the morning can make it hard to get to sleep. These features tint the screen away from the blue spectrum into the red, which is supposed to reduce this effect.
The concept of a night mode on screens is not a new one, having being available on desktop/laptop computers for years, but it is gaining popularity for mobile as devices are increasingly appearing in the bedroom. The theory is quite simple: exposure to light suppresses the production of melatonin, melatonin is a hormone that tells to the body that it's time to sleep. Blue light is very effective as reducing the amount of melatonin your body produces = longer time to fall asleep.
I’ll often find myself scrolling through Twitter in the wee hours of the morning to get the latest news from around globe. With night mode it means you can feel a little less guilty while furiously scrolling through your Facebook, Instagram, Twitter or Snapchat before you nod off to sleep (c’mon, we all do it!). It's also is great for when want to check your emails or social media first thing in the morning without burning your retinas! The other great feature of Night Mode is the set and forget option allowing you to program the time period you would like Night Mode to be active, I usually set it to activate at 11.30pm and deactivate at 7.30 am.
How to enable night mode for Android and iOS:
Android Google Pixel comes with the Night Light already available to enable;
Pull down the notification bar and tap Settings
Scroll down and tap Display
Tap Night Light
Toggle the On/Off Switch to manually control the feature or tap Turn on Automatically
The automatic setting allows you to choose to have it run on sunset/sunrise for your location or you can select a start/end time for the feature.
Don’t have a Pixel? You will need a third party app like these Night Mode ones on Google Play.
iOS Night Shift was enabled in iOS 9.3 and is available to all Apple devices running that version of the software. To enable it;
Open the Settings app
Scroll down and tap Display & Brightness
Tap Night Shift
Toggle to Schedule or Enable Until Tomorrow
The schedule lets you pick a start/end time each day for the feature to turn on/off automatically, unlike Android there is no sunrise/sunset option.
