Study Shows Technology May Inhibit Good Sleep 155
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.

I wonder if the advent of modern LED lighting will allow a programmed shift toward red lights in the evening and a shift from red to blue bias in the morning to allow gradual shutdown and awakening, rather than the shock of an alarm clock or bright lights.

Good job I have Porphyria [wikipedia.org] because I don't even have a "Normal" sleep schedule, it's all over the map.
I don't work in an office (basically impossible with severe Porphyria), so people are always asking me when I sleep because I send business emails 24/7, and am lucky to get a 5 hour night (starting about 4 or 5 am).
Thank goodness for 24/7 Tech accessibility!

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?

Personally, I very, very rarely have trouble sleeping. I usually find myself getting too tired for interactive entertainment about an hour before I want to sleep. I'd *love* to be able to continue playing video games up until lights out, but I just don't have the energy. Those who have lots of energy will keep playing/blogging/hacking.
Based on your /. ID, I reckon most of your inability to continue playing and low energy levels might be age related.

I've had sleeping issues since high school about 10 years ago. Typically, I can't sleep until about 3 AM, and only get about 4 hours of solid rest. After that, I doze in and out of sleep for a couple hours.
I was in Africa for a bit, and regularly had no power - which meant no laptop. My sleep pattern improved drastically during those periods of time. However, the instant power was back I was using the laptop at night again. Immediately, the sleep issues returned. (Note that we did have a generator, so we still had lights and some appliances on when the power was out, but in general avoided turning anything unnecessary on unless we absolutely needed them, like computers).
I've reproduced the same behaviour in myself now that I'm in America. Cut out the laptop at night - start sleeping great in a few days. Re-introduce it: really, really rough week.
