Internal Timing

Meaning

Internal Timing refers to the precise, genetically programmed and environmentally modulated synchronization of an organism’s biological processes, known as the circadian rhythm. This essential physiological function dictates the optimal temporal release of hormones, the sleep-wake cycle, core body temperature fluctuations, and metabolic activity. Maintaining robust Internal Timing is crucial for systemic homeostasis, as misalignment, or chronodisruption, can profoundly impair hormonal health and metabolic function. Clinically, it is often assessed by the phase and amplitude of key hormonal cycles.
