Late Night iPad Reading Could Keep You Up at Night
The iPad could be causing restless nights for many who use it to read e-books before lights out. According to the Los Angeles Times, the light that's emitted from the iPad's screen inhibits the release of melatonin, a chemical that tells your body to wind down for the evening. This holds true for any device that emits unnatural light -- be it a TV or a cell phone. But Frisca Yan-Go, director of the UCLA Sleep Disorders Center in Santa Monica, told the Times that the iPad has a greater effect on preventing the release of melatonin in the body because users hold it so close to their faces. The same, then, goes for cell phones and other gadgets with screens. Thus, watching reruns of 'Family Guy' on the couch is less likely to keep you up than reading a John Girsham iBook under the covers, because of your eyes' proximity to the light's source.But you don't have to give up your e-books. The Kindle and Nook can be used at night with little or no effect on melatonin secretion, Yan-Go says. That's because these devices use e-ink, which doesn't emit light. It also means you can use a Kindle or Nook, unlike the iPad, in direct sunlight -- a crucial fact as summer rears its head. By no means do we think this discovery will cause Apple to lose ground in the e-book market. More than likely, it just means iPad users will look more sleep deprived during the morning commute.

I've had a similar problem with an iMac, and it can happen to you, from the late-night use of any computer/tv screen that emits light, or simply a bright reading light. I've taken to wearing yellow sunglasses when working on the iMac late at night, which, according to their research, inhibit the blue light spectrum responsible for melatonin suppression (the old "Blue Blockers" brand). There is also a company online which sells yellow glasses and clingy film for your computer screens, but I don't recall the name. I'm not an employee of either company, nor do I profit from any sales. But I do sleep better!

I wonder who came up with this story... Uh.... KINDLE (Amazon) Nook (Boarders) maybe?...LOL
elinApr 28th 2010 4:13PM
The Nook is from Barnes & Noble, not Borders. Boarders, by the way, are people who rent a room from you. Like Room & Board.
DigiApr 28th 2010 6:16PM
Actually there is a store called borders books. Research before you start making claims.
WillyApr 28th 2010 10:01PM
@Digi - you're right, there IS a book store chain called Borders, but the Nook was created by and is a product of Barnes & Noble.

The iPad and some recent laptops like the iMac use LED's instead of a florescent tube for illuminating the screen. These have less of an impact on one's bio cycle than fluorescents (CCFL's). Unless this blue component of screen light is bothering just as its blue no matter the source of the light.

Oh and Boarders is more often a term used to refer to SURF Boarders or Body Boarders. People who rent from you are called TENANTS or RENTERS. DUH
ErikaBwitchApr 28th 2010 6:32PM
Oh, Digi? Elin is absolutely correct about the definition of "boarders". DUH. As the saying goes: "It is better to remain silent and be thought a fool than to open your mouth and remove all doubt."
RobbieApr 29th 2010 9:37AM
"dIGI:" You're really going to have to research and READ before you start making claims! At no point did Elin say there was no such store as Borders - you, apparently, just imagined that. Please start paying attention if you're going to take part in this conversation.

I always fall asleep with the lights on when I read. I doubt it hurts me.

The iPad is just another useless toy that everyone wants so they can say "Hey look I have an iPad." What another useless piece of junk.

You can turn off the bright screen(black letters on white background) and read white letters on black background. That is what I have been doing. I find the screen too bright for reading at night otherwise. Of course they don't mention that!!

A. It's hard to comprehend the importance of debating the use and spelling of Borders/boarders when the article is about an iPad and its effect on sleep....
B. there will always be people who are either so addicted to their toy or the brand that they will attempt to defend it somehow despite evidence to the contrary because their identity is unfortunately fused with their choice of purchase
(unless you're a conspiracy nut who connects the UCLA Sleep Disorder Clinic with Amazon by some wierd internal logic)
C. Clearly part of the message is simple:
1. don't use it at night
2. only screens in close proximity have the effect to that degree
3. all screens that emit that kind of light have that effect even if it's only the tv
4. the question I'm still left with is: what if melatonin isn't the sleep inducer (I've attempted to take melatonin to enhance my sleeping and in my system it's actually keeping me awake)

Strange, I find bright lights of TV put me in some sort of a trance and I fall asleep.

Johnson's summary has a real odor to it. The source from which he lifted the story is the LA Times (link). The Times story said that Wall Street Journal found no difference in light effect between iPad and other e-readers. Curious that Johnson somehow "forgot" to include that little factoid. So, who paid him to do so?

Next: Elin said "Boarders, by the way, are people who rent a room from you. Like Room & Board." - 'Digi,'The words "tenants" and "renters" are usually used to refer to people who rent private rooms or apartments with their own facilities - "boarders" is more often used to refer to people who rent a small space, usually a single room, and take their meals ("board") with the landlord/lady and family, as well as other boarders (this definition predates surfboards by many, many years). Hence: "room and board." Generally, to distinguish one from another, surfboarders and body boarders are referred to as "surfboarders" or "bodyboarders," except within a community of same, who may refer simply to "boarders," because they all know what the reference is to.
Oh, no! I ended a sentence with a preposition! This is something up with which we shall not put!
