Personal trend estimate · daily imported summariesDaily HRV, resting heart rate, oxygen and respiration are not confirmed overnight measurements.
About your estimate & sleep data
This estimate uses daily HRV (40%), resting heart rate (25%) and daily sleep total (35%). Heart baselines use the median of earlier matching readings in the previous 28 days, from the same source, measurement method and aggregation. Daily and overnight readings are kept separate. It is our own heuristic, with no WHOOP data or algorithm.
HRV: 70 + 100 × ln(current / baseline). Heart rate: 70 + 200 × (baseline − current) / baseline. Sleep: 100 × hours / 8. Each component is capped to 0–100. The 8-hour reference is a sleep target, not a measured personal requirement.
- HRV · SDNN: awaiting data · 6 earlier readings · Intervals.icu
- Resting heart rate: awaiting data · 5 earlier readings · Intervals.icu
- Sleep total: awaiting data · 6 earlier readings · Intervals.icu
Still needed: HRV · SDNN for this date; Resting heart rate for this date; Sleep duration for this date; 7 earlier HRV readings from the same source, method and aggregation; 7 earlier resting heart rate readings from the same source and aggregation.
No timestamped sleep window imported for this date. A daily sleep total can include naps.
Wrist temperature is labelled as a daily summary or a reading linked to recorded sleep. It is an absolute wrist reading, not body temperature or a deviation from baseline.
