I’ve been really exhausted lately, not feeling like I’m getting a good night’s rest, even if I get 8 hours of sleep. Maybe this is what I need!

The clock that wakes you when you are ready

The clock, called SleepSmart, measures your sleep cycle, and waits for you to be in your lightest phase of sleep before rousing you. Its makers say that should ensure you wake up feeling refreshed every morning.

As you sleep you pass through a sequence of sleep states - light sleep, deep sleep and REM sleep - that repeats approximately every 90 minutes. The point in that cycle at which you wake can affect how you feel later, and may even have a greater impact than how long or little you have slept. Being roused during a light phase means you are more likely to wake up perky.

SleepSmart records the distinct pattern of brain waves produced during each phase of sleep, via a headband equipped with electrodes and a microprocessor. This measures electrical activity of the wearer’s brain, in much the same way as EEG machines used for medical and research purposes, and communicates wirelessly with a clock unit near the bed. You program the clock with the latest time at which you want to be wakened, and it then duly wakes you during the last light sleep phase before that.

The only problem that I see is that the alarm clock could get you up way too early, though that might not be bad if you truly do feel perky. I also wonder what it would be like to where that headband all night. And will this have a snooze button?
