Recognition & signaling
Receptor function, signal detection, communication, and coordination.
Health is a measurable, integrative state of biological, physiological, cognitive, and environmental function governed by receptor performance, signaling integrity, mobility, cardiovascular capacity, autonomic regulation, adaptive resilience, and the body’s ability to detect, respond to, and recover from stressors.
This definition sets a research agenda. Every proposed measure must be evaluated for validity, repeatability, scope, and its relation to the function it purports to represent.
How effectively does a person detect a stressor, produce and transport a response, eliminate or resolve the challenge, and recover? This sequence provides a structure for hypotheses and measurement. It does not reduce all aspects of health to a single test.
Each domain can be studied independently and in relation to the others.
Receptor function, signal detection, communication, and coordination.
Adaptive processes, resilience, and the time course of recovery.
Circulatory capacity, regulation, and response to demand.
Movement, muscular function, and ability to perform daily tasks.
Attention, learning, habits, and responses to the environment.
Conditions that influence function across time and place.
In any proposed model, clear operational definitions and independent tests should precede broad claims.
