Apple Launches Night Shift, for Better Sleep

There are periodic discussions about potential disturbances that the use of smartphones and tablets can cause to those about to go to sleep.
Disturbed sleep, difficulty falling asleep, even outright insomnia: it is hypothesized that using one’s device in bed or at times that should precede rest can interfere with natural sleep-wake cycles.
One of the major problems in this regard would be the exposure of the eyes to the display: the backlighting could disturb some individuals.
While for some, browsing websites and apps directly from their pillow gradually leads to drowsiness, for others, waking up after falling asleep becomes even more bothersome as it is accompanied by the screen’s light.
Apple has therefore decided to at least partially overcome these kinds of issues by introducing a new feature found in version 9.3 of iOS.
Its name is “Night Shift” and, once activated, it will function automatically. Its fundamental mechanism involves using the device’s clock and geolocation system.
In this way, Night Shift can process this data to correctly calibrate the screen’s brightness and color temperatures.

Gradually, the display will reduce blue light – which some studies suggest is responsible for altering the circadian rhythm – thereby rendering warmer color tones, so as not to make falling asleep and sleeping difficult.
In the morning, Night Shift will also restore the usual brightness levels, thus setting differently from evening hours.
All this will happen automatically, without any need to manually adjust the device.
