Wearable Sleep Score
Wearable sleep scores summarize nightly rest from sensors—helpful for trends, not diagnosis—and should pair with how you feel, not perfection chasing.
A wearable sleep score compresses movement, heart rate, and sometimes SpO2 into one nightly number—useful for trends, not clinical diagnosis. Scores differ by brand and reward duration over architecture you cannot see.
Track week-over-week direction alongside how you feel and perform. Chasing a perfect score can worsen orthosomnia.
Common questions
-
Why does my sleep score disagree with how I feel?
Algorithms weight duration and heart-rate proxies differently than perceived rest. Use scores for multi-week trends; adjust habits when both score and energy dip together.
