Internal Performance Signals

Meaning

Internal Performance Signals are the subjective, non-quantitative physiological and psychological cues that an individual perceives regarding their current state of health, vitality, and functional capacity. These signals include subjective feelings of energy, mood stability, cognitive clarity, and physical resilience, which often reflect the underlying status of the neuroendocrine and metabolic systems. Clinically, these signals serve as crucial qualitative data points that correlate with and contextualize objective biomarker measurements.
