The Sleep Score computed by Biostrap is relative measure of quality of today’s sleep session with respect to the quality of your sleep sessions over the last 3 to 30 days.
Factors Affecting the Base Score
- Deep Sleep Percentage
- Total Awake Time
- Time to Fall Asleep
- Average Respiration Rate
- Average Blood Oxygen Saturation Percentage
Each of these factors are given a weight of 20 points.
When the value of any of these factors is off compared to its average over the last 3 to 30 days of sleep, then certain points are deducted.
e.g. If your deep-sleep percentage drops from 22% to 18% for a particular sleep session, then you will lose a certain number of points.
Biostrap computes penalty points for each of these factors. If a particular factor is better than your past average, then there will not be any penalty.
e.g. If your oxygen saturation percentage is the same or greater than your past 3 to 30 day average, no penalty points would be assigned.
You get a Base Score by adding points for all these five factors.
Now Biostrap will compare total sleep-duration with average sleep-duration over last 3 to 30 days. If today’s sleep-duration is lower than your average, then your next sleep-score will be reduced by certain factor.
