Evening Downregulation Phase

Meaning

The Evening Downregulation Phase is the critical period in the late afternoon and early evening where the body naturally initiates a physiological shift from a state of daytime arousal and metabolic activity toward nighttime rest and repair. This transition is characterized by a natural decline in stimulating hormones like cortisol and catecholamines, coupled with the onset of melatonin secretion and a shift toward parasympathetic nervous system dominance. Successfully navigating this phase is paramount for achieving restorative sleep, allowing for proper metabolic clearing, and optimizing the nocturnal anabolic window.
