What is the Origin of Hormonal Cadence?

This term is a conceptual blend of "cadence," implying rhythm and flow, applied directly to the pulsatile and cyclical nature of endocrine signaling observed across chronobiology. It captures the dynamic, time-dependent aspect of hormone action that is often missed in static blood testing. The foundation lies in understanding the pulsatility of the HPG and HPA axes.

What is the Mechanism of Hormonal Cadence?

The SCN dictates the master timing, influencing the pulsatile release of GnRH, which in turn affects LH and FSH, thereby setting the gonadal hormone cadence. Similarly, the timing of light exposure dictates the nocturnal suppression and morning surge of cortisol, which influences peripheral insulin sensitivity. Modifying lifestyle factors to align with this inherent rhythm improves the efficacy of the entire endocrine signaling network.

Hormonal Cadence

Meaning

Hormonal Cadence describes the precise, rhythmic timing and sequencing of hormone release and clearance throughout the 24-hour cycle, reflecting the integrated output of the endocrine system synchronized by the circadian pacemaker. Optimal cadence ensures that hormones like testosterone, cortisol, and thyroid hormones are present at the correct concentrations during required physiological windows. This rhythmicity underpins overall vitality.
