If you walk around feeling groggy and out of it all day, it may be because you are waking up right in the middle of your deepest sleep cycle. This also leads to grumpiness. It is far more ideal to wake up in one of your light sleep cycles, fully refreshed. That’s the idea behind the Natural Sleep Cycle watch.

It uses an accelerometer to keep track of small physiological changes that occur when you are experiencing light sleep. Then it wakes you when the moment is right. I hear you, you have a tight schedule and can’t be late for work. No worries. You can specify how long before your alarm it should start it’s calculations for the best time, from 10 to 90 minutes before. Then it will wake you up with either a vibration or a soft alarm tone.

The price is a bit steep at $179.95 but if it is important to you, you really can’t put a price on a good night’s sleep. Or should I say, a good awakening.
