REM Cycle Integrity

Meaning

REM Cycle Integrity refers to the maintenance of the proper duration, timing, and sequence of the Rapid Eye Movement (REM) phase within the overall sleep architecture. High integrity signifies an adequate amount of REM sleep occurring in the later cycles of the night, which is physiologically essential for emotional regulation, complex learning, and working memory consolidation. Disruptions, such as fragmented or prematurely terminated REM periods, impair these critical cognitive and psychological restorative functions.
