Sleep restriction creates a mild state of sleep deprivation, decreases sleep latency, and promotes more efficient sleep, with less intcrnight variability. 34Interventions curtail the amount of time spent in bed to match sleep efficiency as determined through sleep diaries or actigraphy, with a caveat of a minimum of 5 h in bed. Adjustments are made weekly until optimal sleep duration is achieved. Sleep hygiene education promotes better sleep through awareness of environmental factors (light, noise, temperature, and mattress) and health practices (diet, exercise, and substance use) that may be beneficial or detrimental to sleep.

Typically, these patients sleep better in any place other than their own bedroom. PSG shows increased sleep latency, increased number of awakenings, and poor sleep efficiency.
