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

  1. Deep Sleep Percentage
  2. Total Awake Time
  3. Time to Fall Asleep
  4. Average Respiration Rate 
  5. 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.
