Transcript for Apple Tests New 'Night Shift' Feature on iPhones
Welcome back to "Gma" and so many of us are looking for ways to get a little more sleep. A recent survey, I was surprised by this, said only 19% of adults don't get enough sleep. I thought it would be more than 19%. Me too. Right here. And technology may be part of the reason so let's go over to George who has more on this. Yeah, robin, the problem may be the blue light. I'm here with rich Besser because apple is testing a new feature called light shift that changes it from blue to yellow. It can affect sleep. In primitive days we were governed by the sun. When the sun went down a hormone in our brain called melatonin went up and that made us sleepy. Now we're vouped by artificial light and plea vents that from rising and in particular, one component of light, blue light is really good at suppressing that melatonin rise and our electronic devices put out a ton of blue light. Apple has this idea to move from blue to yellow. Will it make a big difference. If you're on your device all the time and that makes up a big component of blue light, maybe it could make a difference but we get it from all the lights around our home, compact, fluorescent bulbs, L.E.D. Bulbs put out a ton of light. There are these Orange glasses that will filter out all the blue light. It's the Bono look. I don't think I'd like to watch my shows this way but they do all kinds of things to cut down on that. What other kinds of things. In addition to Orange glass, different apps can you get for your phone whether it's android or apple that will slowly decrease the amount of light that comes out of there. In terms of sleep it's not just about that. You need to look at trying to get a routine in before bed so you're easing into your sleep. You want to look at avoiding stimulant, no caffeine after the middle of the day. Make your bedroom dark. If your clock puts out anything other than a red light put a filter on it or get a different color off the clock and separate yourself from electronics at least two hours before going to bed. Good luck with that but it's the right idea. It's hard to do. Rich Besser, thanks very much.
