Sleep Stage Profiling

Meaning

Sleep Stage Profiling is the precise clinical technique of mapping, analyzing, and characterizing the temporal organization and duration of an individual’s sleep architecture across the night. This detailed profile includes the distinct and alternating periods of Wakefulness, Non-REM Stage 1 (N1), NREM Stage 2 (N2), the crucial Slow-Wave Sleep (SWS or N3), and Rapid Eye Movement (REM) sleep. This profiling is essential for the accurate diagnosis of sleep disorders, the rigorous assessment of sleep quality, and correlating specific deficits in SWS or REM with documented hormonal and cognitive dysfunction.
