Sleep seems to be a reoccurring topic here (see my previous post on good sleeping habits), which isn’t surprising seeing as it’s such an interesting subject, even more so when it’s related to technology. Tommy Collison wrote a great post this week about an iPhone app called Sleep Cycle Alarm Clock that helps you wake up more naturally and since trying it out I’ve been acutely aware of the scepticism online surrounding its validity and usefulness.

Sleep Cycle is an app that turns you iPhone into a bio-alarm clock. Using the accelerometer built into the iPhone it reads specific movements common during sleep and wakes you up when you are sleeping lightly, aiming to give you a more refreshing awakening. Haven’t we all felt the frustration of being woken up during an especially interesting dream, and then felt dreadful for the day because of it?

This type of movement based bio-alarm clock has been around for awhile. You often find them as glorified watches with internal accelerometers, or overcomplicated devices that require placing motion detecting electrodes under your pillow case. The reason bio-alarm clocks work is due to the extensive sleep research that tells us how our body moves or doesn’t move during sleep.

How Does It Work?

I’m surprised the phrase “Couldn’t sleep last night.” has yet to trend on Twitter, it’s certainly a common tweet I see in the mornings during my commute to work. Not only that, flicking back through the wee hours of my stream it’s also pretty common to see “Still can’t get to sleep.” appearing at 3am.

I would argue that if you’re tweeting, you’re certainly not trying to sleep or doing what’s good for your body in preparation for shutting down for a few hours. I myself have suffered some restless nights and made a real effort to combat the problem, rather than accepting it and suffering through more zombie like days in the office.

Turn Off Your Computer 30 Minutes Before Sleep

If you’re suffering from occasional difficulty getting to sleep at night you should consider the effects of using a computer late at night. Studies have shown that the brain remains stimulated after using a computer (or watching television), which in turn makes your sleep restless. The simple act of shutting down the computer 30 minutes before you’re planning on going to sleep can help relax you.

Research has also shown that the bright light of your computer monitor (let’s also not forget that mobile phone screens also produce a bright light) suppresses the production of our sleep hormone melatonin. If you are suffering from an especially bad case of insomnia then try shutting down the computer at least two hours before planning on going to bed.

Though you may enjoy the calming effects of using the computer, your brain on the other hand is thinking “light = daytime”. Staring at your computer screen means keeping yourself alert and wide-awake and returning online to complain about your inability to sleep is simply aggravating the problem.
