We've been telling you that your digital devices' brightness isn't good for your sleep. The default cool blue light used by most digital devices can trick your mind into thinking it's daytime, even if you're checking emails in the middle of the night.
Of course, that's not good for your health. Most doctors recommend you get an uninterrupted 7 hours to 9 hours of sleep each night.
As it turns out, Apple is about to help you sleep better, even if you stare at your iPhone or iPad screen late into the night. It's introducing Night Shift with its next update of its mobile operating system, iOS 9.
"Many studies have shown that exposure to bright blue light in the evening can affect your circadian rhythms and make it harder to fall asleep," according to Apple. If you switch Night Shift on (see next page), it will use your Apple devices' geolocation and clock to automatically adjust your screen's brightness at sunset. It will return to its normal brightness in the morning.
