Alarm Wakes According to Body's Sleep Clock
Having trouble waking up in the morning? Your daily battle against the Zs might not be a function of being a bad or heavy sleeper, but could simply be that you're trying to wake up during a particularly deep moment of rest.
The $149 SleepTracker wristwatch monitors your nightly sleep cycles and wakes you up in the morning during an optimal moment of light sleep, which, according to the watchmaker, is the easiest time to unglue your eyelids and hop out of the sack. The SleepTracker is based on the principle that the average adult snoozes through four to five sleep cycles every night, each lasting between 90 and 110 minutes and each made up of five stages. The SleepTracker's internal sensors measure your body's physical signals during sleep to determine when you've entered the lighter stages of sleep in any given cycle. Instead of an exact time, you set the watch with a window of time in which you'd like to get up. When you've reached the lightest stage of sleep inside of that time frame, the watch wakes you up. Since you're not being shocked awake during a coma-like stage of deep sleep, you're more alert and as ready as ever to seize the day (or at least seize a tall stack of flapjacks).
