The WHOOP Healthspan Feature: Advancing Personalized Longevity Insights with Wearable Data

What this work gives Aellic

WHOOP's own description of WHOOP Age: nine inputs mapped to published all-cause mortality hazard ratios and converted with 10 × ln(HR), measured against a health-optimised reference so that meeting the recommendations gives the calendar age. Resting heart rate during sleep is neutral at about 60 bpm for men and 64 bpm for women (derivation unpublished). The age uses the last 6 months, the pace of aging the last 30 days projected 6 months ahead on a scale of -1.0x to 3.0x; it updates weekly and unlocks after 21 recoveries in 31 days. Industry document without peer review; its overlap corrections are unpublished. Aellic takes the resting heart rate neutral points, the unlock rule and the pace formula from it.
