The okes over at Apple are really clever. You know when you swipe down on your screen and you can get all that wonderful information such as the date, the weather and HOW LONG IT WILL TAKE FOR YOU TO GET TO WORK? Well, now they are using all that data to make you get to sleep easier. Sweet, nê?
At night time, your phone’s display is predominantly made up of blue light. Now, with the iOS 9.3 update, you will be introduced to Night Shift. Apple’s vice president of product marketing, Greg Joswaik, explains:
Night Shift uses your device’s clock and geolocation to know when it’s sunset in your location.
You phone then automatically changes the colour of the iPhone’s display to the warmer, yellow end of the spectrum, reducing the amount of blue light pouring out of your phone.
You can also activate Night Mode manually by swiping up from the bottom of your iPhone, then tapping the sun-and-moon icon next to the calculator.
But other than that, why should one use it? Here’s a short explanation:
That’s because blue light tricks our circadian rhythm, or natural body clock, into thinking that it’s daytime. It also boosts attention and reaction times, and interferes with our bodies’ production of melatonin, the hormone that induces sleep, making it difficult to nod off.
It’s not just your sleep that suffers, either; multiple studies have linked exposure to blue light and disrupted circadian rhythms to heart disease, diabetes, obesity and even cancer. Harvard researchers were able to increase blood sugar levels and lower the level of leptin, a hormone that causes people to feel full after a meal, in 10 people simply by changing their circadian rhythms.
Here’s a before:
And here’s the after:
