Nocturnal Hormonal Pulses

Meaning

Nocturnal Hormonal Pulses describe the characteristic, episodic bursts of hormone secretion that occur predominantly during the sleep period, which are crucial for physiological repair, growth, and metabolic regulation. Key hormones exhibiting this pulsatile release include Growth Hormone (GH), Prolactin, and Gonadotropin-Releasing Hormone (GnRH), which subsequently drives testosterone production. These secretory patterns are tightly linked to specific sleep stages and the body’s circadian rhythm. Disruption of normal sleep architecture can significantly impair the amplitude and timing of these essential pulses, negatively impacting health.
