Apple introduces Night Shift feature which will change screen’s color during night

Apple has introduced an exciting Night Shift feature in iOS 9.3 in which the color temperature of the display shifts from blue spectrum of light to warmer tones to improve sleep quality. Many research papers have blamed the light emitted from mobile devices as a major hindrance in sound sleep. The use of mobile phone or other gadget before sleep impacts sleep quality. But experts have said that there is no concrete evidence that mobile screen’s color temperature could be blamed to keep you up at night.

In fact, Apple has also not made any promises about the impact of this feature on sleep quality. The company said, “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”.

The new feature allows you to change color temperature, but experts said that it might be helpful with sleep patterns. There are also chances that the feature may not prove beneficial at all.

The best way to have a good night sleep is to turn off screens two hours before you go to bed. Medical experts have even suggested people facing sleep issues to use warmer lighting throughout the house during the late evening hours. Circadian rhythm, a biological cycle, is commonly associated with sleep and wakefulness.

The cycle is of 24 hours and the body uses many cues to keep a track of it. If one gets out of sync then it means illness, obesity, diabetes and increased risk of cancer. Since the time light receptor type has been discovered, scientists have discovered it to many things like light and melatonin suppression.

Apple’s new feature is being available to around 500 million devices via iOS 9.3 only devices released in starting in around 2013 have the hardware that support the feature. But it is not known completely whether a shift of light from blue to yellow could improve sleep. Experts think that slight reduction in color blue would not show effect.
