Shift work sleep disorder: prevalence and consequences beyond that of symptomatic day workers.
TLDR
It is suggested that individuals with shift work sleep disorder are at risk for significant behavioral and health-related morbidity associated with their sleep-wake symptomatology.
Vulnerability to stress-related sleep disturbance and hyperarousal.
TLDR
The results showing a relationship between FIRST scores and nocturnal polysomnography and Multiple Sleep Latency Test scores suggest individuals with high FIRST scores may be predisposed to developing chronic primary insomnia and the vulnerability identified may underlie vulnerability to transient sleep disturbance associated with other sleep-disruptive factors.
Sleep loss and REM sleep loss are hyperalgesic.
TLDR
These studies showed that the loss of 4 hours of sleep and specific REM sleep loss are hyperalgesic the following day, implying that pharmacologic treatments and clinical conditions that reduce sleep and REM sleep time may increase pain.
Sleep in lifetime posttraumatic stress disorder: a community-based polysomnographic study.
TLDR
No objective evidence for clinically relevant sleep disturbances in PTSD was found and an increased number of brief arousals from REM sleep was detected in subjects with PTSD.
Caffeine: sleep and daytime sleepiness.
Sleep, Sleepiness, and Alcohol Use
TLDR
It is found that in nonalcoholics who occasionally use alcohol, both high and low doses of alcohol initially improve sleep, although high alcohol doses can result in sleep disturbances during the second half of the nocturnal sleep period.
Effects of rapid versus slow accumulation of eight hours of sleep loss.
TLDR
"Rapid" sleep loss produced significantly more impairment on tests of alertness, memory, and performance compared to the "slow" accumulation of a comparable amount of sleep loss, suggesting the presence of a compensatory adaptive mechanism operating in conjunction with the accumulation ofA sleep debt.
