What wearables can measure
Motion, HR, HRV proxies, temperature — combined into staging algorithms. Accuracy vs medical sleep studies varies.
Ring vs band vs mattress
Rings: comfort, all-day wear. Bands: workout + sleep. Mattress pads: partner disturbance, no wearables — different failure modes.
How to use scores
Track interventions against your own baseline. A single bad night score is noise; four-week trends are signal.
