Circadian Rhythm of Willpower

Meaning

The Circadian Rhythm of Willpower describes the predictable, endogenous fluctuation in an individual’s capacity for self-control and inhibitory regulation that occurs over a 24-hour cycle, synchronized by the body’s master clock. This rhythm dictates that the mental energy available for complex decision-making and impulse resistance is not constant but varies systematically throughout the day. Recognizing this rhythm is clinically useful for timing demanding tasks to periods of peak cognitive resource availability.
