Sleep Fragmentation Reduction

Meaning

Sleep fragmentation reduction is the clinical objective of minimizing the number and duration of brief arousals or awakenings that interrupt the continuity and restorative quality of the sleep cycle. Fragmented sleep prevents the necessary progression through the deeper, reparative stages, including slow-wave and REM sleep, even if the total time in bed is adequate. This reduction is vital because fragmented sleep is directly linked to hormonal dysregulation, impaired glucose metabolism, and diminished cognitive function. Achieving sleep continuity is a prerequisite for systemic physiological restoration.
