Tracking Sleep Data

To review your sleep data, press MODE to go to DATA REVIEW.

Use the left buttons to review your almost-awake moments. SLEEPTRACKER^® records and stores your almost-awake moments for one day, so in the DATA REVIEW mode you can discover how many times you were almost awake during a night and the average time between those moments. Each almost-awake moment is displayed in chronological order as "Data 1," "Data 2," etc. At the end of this series of times, SLEEPTRACKER^® displays "Data A," the average time between your almost-awake moments.

Data A can help you know how soundly you're sleeping. If the average time between your almost-awake moments is relatively long compared to other nights, you've probably slept more restfully than usual. If you go to bed and get up at the same times most days, your sleep patterns are likely to be consistent - and Data A will remain fairly consistent, too.

Remember that everyone's sleep patterns are different, and everyone's Data A is different. Almost-awake moments may be frequent or occasional, sporadic or regular. A 20- to 30-minute Data A is not uncommon. Moreover, multiple almost-awake moments can occur within one sleep cycle. To best assess your sleep, look to see whether your Data A lengthens as you continue to use the SLEEPTRACKER^®. An increasing Data A means you're getting more onsistent sleep. Also, look at your sleep data to make sure you have extended periods of sleep without almost-awake moments. If that's the case, a short Data A is no cause for worry, since you're getting sufficient periods of deep sleep.

To establish your personal baseline, keep track of Data A for 7-10 nights so you can find out how restless each night's sleep was relative to the others. The more almost-awake moments you have (based on your individual norm), the less restful your night's sleep. If your sleep is consistent, Data A will probably only vary by a few minutes from one night to the next. If Data A deviates significantly from your normal baseline one night, think about what you did before going to sleep that might have affected your sleep cycle. Factors like alcohol, cigarettes, late evening exercise, eating late, and spicy foods can all affect your Data A. After SLEEPTRACKER^® records an almost awake-moment, it will not record another one for 8 minutes.

This is to keep SLEEPTRACKER^® from recording multiple almost-awake moments because you get up in the middle of the night. If you stay up for more than 8 minutes, SLEEPTRACKER^® will record an awake moment every 8 minutes until you go back to sleep. Within the ALARM WINDOW, however, SLEEPTRACKER^® triggers the alarm at your first almost-awake moment.
