Deep Sleep Physiology

Meaning

Deep Sleep Physiology encompasses the specific neurobiological and systemic processes that characterize the non-rapid eye movement (NREM) Stage 3 sleep, also known as slow-wave sleep (SWS). This stage is physiologically restorative, marked by high-amplitude, low-frequency delta brain waves. During this period, the body undergoes critical repair, energy conservation, and significant hormonal release. Maintaining robust deep sleep is directly correlated with enhanced physical recovery and metabolic regulation.
