What is the Origin of Sleep Architecture Hormones?

This term combines the structural description of sleep stages (architecture) with the physiological control exerted by hormones like melatonin and growth hormone. Its origin highlights the endocrine basis for the cyclical nature of human rest.

What is the Mechanism of Sleep Architecture Hormones?

Melatonin secretion, driven by darkness, initiates the onset of sleep and influences the timing of the first SWS bout. Subsequently, the deep sleep stage triggers the pulsatile release of Growth Hormone, which is vital for physical restoration. Cortisol exhibits a characteristic rise just before the natural awakening time, completing the hormonal governance of the sleep cycle.

Sleep Architecture Hormones

Meaning

Sleep Architecture Hormones refers to the key endocrine signals whose temporal release patterns define and govern the structure and progression through the various stages of sleep, including NREM and REM. These hormones are intrinsically linked to the maintenance of the circadian rhythm and the homeostatic sleep drive. They are both responders to and regulators of sleep quality.
