One of the highlights of the recently released iOS 9.3 beta was Night Shift, a brand new feature for iOS that aims to reduce eyestrain and make it easy for you to fall asleep. This is a brand new feature for iOS, though the concept behind it isn’t – various apps and programs that boast similar functionalities have been available on most platforms for a long time now, with one of the most popular ones being f.lux. For a brief time, it was also available on the iPhone, but Apple killed it off as it reportedly violated the company’s Developer Program Agreement.
Night Shift aims to keep your organism in line with the 24-hour “circadian rhythm”, which is crucial for your sleep patterns. Indeed, numerous studies have found that if you’re subjecting yourself to bright blue light right before bed, you are messing up with the levels of melatonin in your body. Turns out melatonin is a pretty important hormone that regulates your sleep timing – it is tightly-tied with the circadian rhythm and the natural lighting conditions.
