Sleep Score
The optimal range for Sleep Score (Nightly Sleep Quality Score) is commonly cited as 80+ (Oura) or "Fully Recovered" (Whoop) consistently, tighter than the standard lab reference range of 0–100 (normalized by wearable platform). Composite sleep metric from wearables - combines duration, efficiency, and deep/REM ratios into one number.

What Sleep Score Measures
Sleep score is the composite metric most wearables produce nightly - Oura, Whoop, Apple Watch (via iOS 17+), Garmin, Fitbit. Each uses slightly different algorithms, but they all combine sleep duration, efficiency (time-asleep / time-in-bed), and sleep architecture (time in deep + REM stages) into a normalized 0–100 (or color-coded) score.
Individual platforms aren't comparable to each other (Oura 85 ≠ Whoop 85), but each is internally consistent. Track YOUR score over time within one platform.
Sleep score is the single most informative recovery metric - more than HRV or RHR alone - because it integrates those signals alongside duration and architecture. Consistently low scores (< your personal average minus 15%) over multiple days is a strong signal that something's disrupting recovery: protocol change, alcohol, stress, or illness.
What Affects This Biomarker
Sleep score is influenced by: sleep duration, sleep timing regularity, alcohol (reliably tanks it), late caffeine, late heavy meals, screen use before bed, room temperature, stress, and pharmacologic agents - anything elevating sympathetic tone (stimulants, cortisol) lowers it; sleep aids increase duration but often degrade architecture. Peptides: BPC-157, Epithalon, tesamorelin, HGH all commonly improve sleep scores over weeks.
In the Context of Peptide Protocols
GH peptides (tesamorelin, ipamorelin, CJC-1295, HGH) typically produce noticeably better deep sleep scores within 1–3 weeks - this is one of the most consistent subjective benefits users report. Epithalon shifts scores via melatonin axis effects. On GLP-1s, sleep scores often improve slowly as weight drops. StackAI reads sleep score trends as a proxy for protocol-induced recovery quality.
