What is it? The Sleeptracker is a sleep-monitoring device worn on the wrist like a regular wristwatch that measures and records nightly sleep patterns. An internal alarm wakes the wearer at the ideal point in their sleep cycle to ensure a refreshed, alert start to the day.

How does it work? An internal accelerometer measures sleep patterns and detects 'almost-awake' moments during light sleep. To use, set the alarm to a specific time and enter a 'window' of about 30 minutes leading up to the alarm. The theory is that it's better to wake up at an almost-awake time than to sleep until the alarm rings.

Why do I need one? Quality of sleep affects health and brain functions, such as those controlling mood and memory. Throw in long-distance travel across time zones and it's no wonder most travellers arrive feeling groggy. The Sleeptracker wakes the wearer at the best time to avoid the inertia associated with jet lag and provides a digital record of the night's sleep patterns. The wearer can use this information to ensure better quality sleep.

Anything else we should know? The Sleeptracker also functions as a watch. It's lightweight and water resistant, has a night-glow feature, uses a replaceable CR2032 battery and has a one-year warranty.

Where can I find one? The Sleeptracker costs US$149 and is available at www.sleeptracker.com.
