Breaking News: Study Finds Glow from iPads Still Disrupts Sleep

The Washington Post revealed some shocking news today. Even though decades have passed since the issue was first identified, apparently staring into a backlight screen late at night will still affect your sleep pattern.

From the Washington Post:

Basking in the blue glow of tablets, smartphones and other electronic devices before bedtime could be messing up our sleep patterns more profoundly than we realize, and even affecting our long-term health, according to a new study published Monday in the Proceedings of the National Academy of Sciences.

"It may be having a greater impact than we previously thought," said Anne-Marie Chang, a professor at Penn State University and a co-author of the study, which was conducted at Brigham and Women's Hospital in Boston.

A growing body of evidence has suggested what many people have experienced firsthand — that the pervasive glow of electronic gadgets can hinder a good night's sleep. But researchers behind Monday's study, which was supported by a grant from the National Institutes of Health, set out to decipher what changes in the body cause those disruptions.

I don't know about you, folks, but I'm surprised this counts as news.

4509414112_edea794d4d_o[1]I can recall reading stories for at least the last 4 years which said basically the same thing. Here's one from CNN in 2010, for example, and here's another story from WebMD in 2012, and then there's this story published on Medical Daily in 2013.

All 3 stories cited medical professionals, and the last two even mentioned the results of studies which showed the connection between using an LCD screen and a negative impact on your sleep pattern. What's more, these are just 3 of the dozens of stories written on this issue in the past 5 years; you can find more by Googling "iPad melatonin".

Aside from the astounding detail that the Washington Post reporter didn't find those older stories, there's really not much in the way of news here today.

Everything quickly spiraled out of control from there. Before I started this blog in January 2010 I covered ebooks, ebook readers, and digital publishing for about 2 years as a part of MobileRead Forums.

  1. As often is the case with popular media accounts of research findings, you’ll do better to read the abstract of Prof. Chang’s paper itself, at http://goo.gl/qkc7m9. Note that the full paper is available for free d/l from this page.

    As is to be expected from a paper published in PNAS, her work expands the knowledge of this issue, much of which has been casual or anecdotal. There’s still a lot to be learnt, however, and the paper points some of it out.

    • This is true, Will, but I don’t see the need to do so. I’m not that interested in this area of physiology. My interest was satisfied by previous papers which also showed the connection.

      But thank you for the link.

  2. Apple, a negative trend setter that is now stunted, pushed everyone to these pixel wars (gorgeous display!) which may be a factor for the current stagnation when it comes to screen technology. There is a lot of promising technology out there that can push away from back lit screens and is far more energy efficient e.g. LiquaVista’s electrowetting technology. I believe Samsung’s Superamoled display, which is genuinely innovative, isn’t backlit and the display is far easier on the eye than LCD.

  4. I wonder if any of the people in this study tried reading with the screen inverted, white text on black background. That’s easier on my eyes, and uses less battery power too. I read this way every night before bed, and I haven’t had any problems.

  5. This is why some journalists I know (particularly those working for newspapers or weekly magazines) have for years taken to wearing orange safety glasses when we’re working late at night. It stops the blue light getting in and you sleep better. It took a while to find a pair that fits over your vision glasses, but Amazon sells some for about 8 bucks.

    I just switch the theme in Moon+ to yellow letters on black background, and dial down the brightness to 65-75%… bright enough to read, but dim enough to do it next to my sleeping wife. And no blue at all, so I can lay it down and slip right into slumber.

  7. My daytime theme is black on yellow, but same effect: no blue.

    For my workday use I set my desktop monitor to zero out all blue, adjust settings/scheme so the result doesn’t frighten me, and it is far less tiring.

  8. bloggers should stick to blogging, instead of trying to analyze scientific research.
