Trouble Sleeping? Maybe It’s Your Laptop…or Xanga?

More than ever, consumer electronics — particularly laptops, smartphones and Apple’s new iPad — are shining bright light into our eyes until just moments before we doze off. In fact it is 1:30 AM and I am on Xanga writing this blog.

Now there’s growing concern that these glowing gadgets may actually fool our brains into thinking it’s daytime. Exposure can disturb sleep patterns and exacerbate insomnia, some sleep researchers said in interviews.

“Potentially, yes, if you’re using [the iPad or a laptop] close to bedtime … that light can be sufficiently stimulating to the brain to make it more awake and delay your ability to sleep,” said Phyllis Zee, a neuroscience professor at Northwestern University and director of the school’s Center for Sleep & Circadian Biology.

“And I think more importantly, it could also be sufficient to affect your circadian rhythm. This is the clock in your brain that determines when you sleep and when you wake up.”

Such concerns are not entirely new: One sleep researcher said Thomas Edison created these problems when he invented the light bulb. But they’ve been revived by the popularity of Apple’s new slate computer, the iPad, which many consumers say is good for reading at night in bed, when the brain thinks the environment should be dark.

Unlike paper books or e-book readers like the Amazon Kindle, which does not emit its own light, the iPad’s screen shines light directly into the reader’s eyes from a relatively close distance.

That makes the iPad and laptops more likely to disrupt sleep patterns than, say, a television sitting across the bedroom or a lamp that illuminates a paper book, both of which shoot far less light straight into the eye.

My mom always said don’t sit so close to the TV…I guess she was right.

  1. LOL I couldn’t agree more. I can be overly tired but as soon as I get either on my computer or my itouch ; i’m wide awake, maybe I should read more books & save on sleep lol ; good post ! =)

  2. My wife has trouble going to bed before 4am, even if she has work in the morning.  Oddly enough, she is on Xanga for hours and hours… and hours…. This method of making a 28 hour day works for chickens.  It might work on us as humans, too.

  3. there’s this software called F.lux that adjusts the brightness of your screen based on the time of the day. it’s supposed to help you with your sleeping pattern too. i’ve been using it for a month now and it actually works! i have been sleeping much earlier with the same amount of computer usage as before. you should try it out!

  4. Computers actually make me more sleepy. They hold my attention, and forbid me to turn away, even when there’s nothing really going on on the screen, but they still make me sleepy. But at the same time, I still think they might be right about the computer. I think the computer is a huge source of problems. But at the same time, I just can’t look away.
