Study Shows Technology May Inhibit Good Sleep 155

Posted by Soulskill from the it's-hard-to-sleep-without-all-the-beeps dept.
An anonymous reader points out a study by the National Sleep Foundation which looked at the relationship between sleep habits and the use of electronic communications tech in the hour before bedtime. Dr. Michael Grasidar of Flinders University said, "My research compares how technologies that are ‘passively received' such as TVs and music versus those with ‘interactive' properties like video games, cell phones and the Internet may affect the brain differently. The hypothesis is that the latter devices are more alerting and disrupt the sleep-onset process." The study found that people who frequently send text messages or use their laptops before bed were less likely to report getting a good night's sleep (PDF) than people who don't. "While these technologies are commonplace, it is clear that we have a lot more to learn about the appropriate use and design of this technology to complement good sleep habits," said the NSF's David Cloud.

          My boyfriend watches TV on his laptop to help him sleep, but he uses headphones so that my falling asleep isn't affected by it. I had to get used to the extra brightness, but that didn't take very long. I couldn't fall asleep at all, though, when he didn't use headphones.

I think it has to do with the way I've never bothered investing specifically in quiet fans on PC's I've built, and as they've become more and more powerful they just became louder until the point where I need some background noise to fall asleep. Otherwise I can hear a bit of stuff from neighbors and such, and those background noises overlaid on the "loud scilence" is annoying.

        And one has to wonder if it's actually the technology or the person on the other end of the computer that's causing lost sleep. If I spend an hour before I go to bed dealing with work email (which at this hour is largely generated in Taiwan/China), I don't sleep well, only because those idiots are screwing up and this comes back to me.

        Whereas in the pre-computer era I guess you left work at a reasonable hour and had some down-time before bed. Although I hesitate to guess that one filling my job in this era would have been up equally long identifying and requesting fixes to mistakes made overseas and sending them a long, angry memo, before driving home and sleeping.

        So maybe the real cause of lost sleep is the blurring line between work life and personal life and/or the increasing productivity demands of a shitty economy and a lack of viable options for employees?

        I still need to spend less time on a computer in the evenings, I think too much sitting at a desk or cramped up with a laptop is bad for me.

      • It looks from the f.lux page that the application automatically adjusts the light based on where you live.

        I'm a night shift worker and have trouble getting to sleep when I arrive home at 5 AM. The sun has just come up then, so I imagine that the computer screen will be at full brightness.

        Would it be advisable to somehow try to fool f.lux into thinking I live in a place where normal people are about to go to sleep, or are the default setting better even if you need to be awake at night and sleep in the day?

        • IIRC (it's on my home computer) f.lux changes the colour profile of your desktop towards red, which is like sunset/firelight/sleeping time, and away from blue which is like bright daylight. It's usually set based on its calculated dawn/dusk times from the time on your computer and the location you enter in the settings. I'm sure you can either override the location or just lie to it - you'd want the 'night' colour while you're meant to be getting sleepy.

          Anyway, it's a free tiny download so just give it a go

          • Thanks, Tempe. I live in Tokyo and it's 5:25 AM here; I'm going to bed in half an hour. I told F.lux that I was in Dublin so that my computer behaves like it's early evening, and the screen is a bit reddish, as if a sunset were streaming in from behind me.
