Norepinephrine Arousal

Meaning

Norepinephrine Arousal describes the state of heightened physiological and psychological vigilance mediated by the rapid release of the catecholamine neurotransmitter norepinephrine (also known as noradrenaline). This state is a core component of the body’s sympathetic nervous system response, integral to the fight-or-flight reaction. In hormonal health, this arousal is a necessary acute response to stress, but chronic, unremitting norepinephrine release leads to allostatic overload, contributing to HPA axis dysregulation and systemic fatigue. Precise control over this arousal mechanism is vital for maintaining sustained energy and focus.
