Sleep Stage Biochemistry

Meaning

Sleep Stage Biochemistry refers to the distinct, stage-specific changes in neurotransmitter activity, hormone secretion, and metabolic rate that characterize the different phases of the sleep cycle. This discipline examines the complex neurochemical shifts that facilitate the transition from wakefulness through NREM sleep to REM sleep. Understanding this biochemistry is essential for interpreting sleep quality, as each stage serves unique restorative and regulatory functions dependent on a precise chemical environment. The underlying molecular changes are key to the restorative properties of sleep.
