Principlev1
Use vigorous physical activity for twenty to sixty minutes
Use vigorous physical activity for twenty to sixty minutes to metabolize stress response chemicals and signal cycle completion to the nervous system.
Why This Is a Principle
Derives from understanding of stress physiology (Subcortical Fast-Pathway Threat Processing on amygdala activation, Dopamine neurons encode prediction error rather than on dopamine/prediction error, Emotions prepare the body for specific physical actions on physiological preparation). The specific duration and intensity prescription follows from the neurochemical half-lives and completion signals.
