Here’s why we think we should all upgrade to iOS 9.3. It may make us sleep better.
Get this: With the upgrade, you’ll get a new and totally cool, science-backed feature: Apple is introducing Night Shift, a new setting that uses your iOS device’s clock and geolocation to figure out when it’s sunset in your location. When the sun goes down, the display on your mobile device automatically modulates to warmer tones that are far less stimulating to the brain.
So what’s the big deal? Namely, that blue-light emitting devices (your phone, computer, tablet and TV) can interfere with melatonin production in your brain. Study after study confirms that exposure to blue light before bedtime leads to less melatonin productions, which in turn causes poorer quality sleep.
Night Shift will dramatically reduce the amount of blue light emitted by that beloved iPhone at night, meaning it will do less damage on your zzzz’s to check in on Facebook, text and read stories on your device before getting some shut-eye.
And if you want to dig even deeper into the blue-light issue, you may want to know that electric light bulbs can do even more damage to our melatonin production. One study found that exposure to LED lights before bed suppressed melatonin in 99% of people. Pretty compelling information!
A potential solution might be in switching lightbulbs. Some companies are offering lighting sources that are designed specifically not to interfere with melatonin production. And while the price tag might cause a bit of sticker shock ($39 a bulb?!?), for many the idea of a good night’s sleep may be priceless.
