What the Nexus Score measures.
◎
Heart Rate Variability (HRV)
The primary marker of autonomic nervous system balance. High HRV correlates with strong recovery capacity. Low HRV signals accumulated stress, poor sleep, or overtraining. Measured at rest, pre-session.
◈
Autonomic State (ANS)
Sympathetic vs. parasympathetic nervous system balance. Nexus reads your autonomic state to determine how aggressively the recovery protocol should push thermal or hydrotherapy load.
◉
Sleep Architecture
If integrated with wearable data, the system accounts for prior-night sleep quality — including REM and deep sleep ratios — as an input to the Nexus Score computation.
◌
Resting Heart Rate (RHR)
A secondary marker used to contextualise HRV readings. Elevated RHR relative to personal baseline is a signal for reduced session intensity.
The 0–100 Nexus Score
Your biomarkers are normalised, weighted, and mapped across 7 readiness bands — from Deep Deficit (0–14) to Peak Recovery (86–100). The score determines protocol intensity, modality sequencing, and session duration. Post-session, the difference between entry and exit score provides a measurable indicator of acute physiological response.

Frequently asked questions
What biomarkers does Nexus Care measure?
Nexus Care measures Heart Rate Variability (HRV), Autonomic Nervous System state, sleep architecture (via wearable integration), and Resting Heart Rate. These four inputs are combined to compute the 0–100 Nexus Score.
Why is HRV the primary recovery marker?
HRV measures the nervous system's capacity to adapt to physical and mental demands. High HRV correlates with strong recovery capacity and emotional flexibility. Low HRV signals accumulated stress, poor sleep, or overtraining.
What are the 7 readiness bands?
The 7 readiness bands range from Deep Deficit (0–14) to Peak Recovery (86–100). Each band corresponds to a physiological state and determines the recovery protocol — sauna temperature, infrared wavelength, hydrotherapy sequencing, and session duration.
Is the Nexus Score scientifically validated?
The Nexus Score is built on established biomarkers used in clinical performance monitoring and autonomic neuroscience. HRV, ANS balance, and resting heart rate are well-studied recovery indicators in sports medicine and clinical research.
