Energy Crashes

Meaning

Energy Crashes describe sudden, profound, and often debilitating periods of physical and mental exhaustion that occur following a brief surge of energy or activity, representing a significant failure in the body’s capacity for sustained energy homeostasis. Clinically, these episodes are distinct from simple fatigue and are frequently linked to acute dysregulation in core metabolic and endocrine pathways, particularly rapid fluctuations in blood glucose and insulin signaling. In the context of hormonal health, energy crashes often signal underlying adrenal fatigue, chronic cortisol rhythm disruption, or mitochondrial dysfunction that compromises cellular ATP production. They severely impact daily function and overall quality of life.
