Sleep History Tracker

The Sleep Tracker is designed to track everything about your nocturnal downtime. You can track hours of sleep per day (broken down between overnight and naps), track sleep interruptions and sleep quality, as well as when you use sleep aids.

All of this data is valuable just by itself – in fact there are apps out there today that do only this, but CPT will also analyze the impact of sleep on your pain levels (and vice versa).

Diary Entry Input

Using the sleep tracker is quite easy. Let’s take an example scenario of your first diary entry of the day. You would add the Sleep Tracker and first indicate the Hours of Sleep for the previous night. Just drag the slider to indicate the amount to the nearest 15min interval.

Next, you can record the time it took you to fall asleep. This can be helpful when determining if a sleep aid might be justified. The tracker defaults to the Overnight sleep type, so nothing to do there. If you did use a sleep aid, flip the switch to indicate it.

Finally, you can indicate how many times your sleep was interrupted during the night and a value for the overall quality of the sleep. That’s it.

In the case of an afternoon nap, you would follow the same procedure, just tap the Nap selection for sleep type so it can be tracked separately.

Summary Report Graph Samples

Daily Sleep Totals vs Time

This combination graph shows your daily sleep totals as vertical bars. The dark blue portion indicates Overnight sleep while the light blue portion represents naps taken that day. The horizontal blue bar shows the average daily sleep hours for the reporting period.

The sleep data is overlaid with the reported pain intensity levels for the same period, shown in red. You can use this graph to look for any degree of correlation between your pain and sleep levels. You can also compare this graph between reporting periods to see if your sleep hours are increasing or decreasing and how/if that correlates to your pain levels.

Pain Level vs Hours of Sleep

This chart aggregates the data from all Diary Entries during the reporting period that included a Sleep Tracker and Pain Intensity level tracker.

For each day in the period, the total sleep hours and overall average pain level is calculated. A graph is then generated where for a given range of sleep hours, the daily pain level range can be plotted.

This graph can help determine if your sleep hours are having an impact on your overall pain levels.

Sleep Interruption Frequency

This graph provides an indication of how many times your sleep is being interrupted. This information can be helpful when evaluating the impact your pain is having on your ability to sleep and/or whether or not sleep aids are suggested.

Time to Fall Asleep

This chart provides insight into how long it typically takes you to get to sleep at night. The bars of the chart represent the frequency that the particular time period was cited during the period. For example, in this graph, 55% of the time sleep came immediately for the diary owner, while 40% of the time it was within about 15min of laying down.

This chart can be used to identify whether or not the owner’s pain levels are causing unnecessarily long periods of restlessness where the individual is unable to get to sleep.

Sleep Hours vs Sleep Aid Usage

This graph will show the difference in overnight sleep hours between nights when a sleep aid is taken versus nights it is not.

The bars show the range of overnight sleep hours under each scenario and the green lines represent the average overnight sleep hours in each scenario.

Pain Level vs Quality of Sleep

Rating the quality of sleep is quite subjective, but we all know the feeling of a really good night’s sleep and how that can help keep us going the next day. This graph looks at the impact of sleep quality on the avg pain levels experienced following that sleep cycle.

As in similar graphs in the report, the bars represent the range of pain levels experienced and the green lines are the average pain level for a given range of sleep quality.
