Sleep architecture refers to the structure of sleep cycles throughout the night and the five stages of sleep including four stages of non-rapid eye movement (NREM) sleep and the fifth stage, rapid eye movement (REM) sleep.
Sleep architecture allows for the quantification of sleep characteristics in order to promote accurate diagnosis of sleep disturbance or related medical or psychological diagnoses. Some relevant measures of sleep architecture include the following:
Sleep onset latency – the time between initiating sleep behavior (lights out) to onset of first sleep stage
REM latency – the time between sleep onset and occurrence of first REM period
Total sleep time – total time (in minutes) sleeping from lights out to lights on
Sleep efficiency – ratio of time asleep compared to time recording (lights out to lights on)
Measurement of sleep architecture: Sleep architecture is mapped out by the cyclic series of...
