“…Since there was no main effect of sleep dose on the abovementioned moods, these findings suggest the environment in the laboratory, which involves minimal exposure to natural light and reduced opportunity for exercise or socialisation, may impact mood during a multi-day sleep study. Indeed, healthy adults reported reduced happiness and increased depression following nine consecutive nights of nine hours' time in bed in a laboratory when compared to baseline assessments [13]. Together, it seems the laboratory setting does not cause negative affect per se but may contribute to a decrease in overall positive mood.…”

Consecutive Nights of Moderate Sleep Loss Does Not Affect Mood in Healthy Young Males

Sleep loss causes mood disturbance in non-clinical populations under severe conditions, i.e., two days/nights of sleep deprivation or a week of sleep restriction with 4–5 h in bed each night. However, the effects of more-common types of sleep loss on mood disturbance are not yet known. Therefore, the aim of this study was to examine mood disturbance in healthy adults over a week with nightly time in bed controlled at 5, 6, 7, 8 or 9 h. Participants (n = 115) spent nine nights in the laboratory and were given either 5, 6, 7, 8 or 9 h in bed over seven consecutive nights. Mood was assessed daily using the Profile of Mood States (POMS-2). Mixed-linear effects models examined the effect of time in bed on total mood disturbance and subscales of anger-hostility, confusion-bewilderment, depression-dejection, fatigue-inertia, tension-anxiety, vigour-activity and friendliness. There was no effect of time in bed on total mood disturbance (F(4, 110.42) = 1.31, p = 0.271) or any of the subscales except fatigue-inertia. Fatigue-inertia was higher in the 5 h compared with the 9 h time in bed condition (p = 0.012, d = 0.75). Consecutive nights of moderate sleep loss (i.e., 5–7 h) does not affect mood but does increase fatigue in healthy males.

“…However, sleep deprivation of healthy subjects impairs mood as assessed using the Profile of Mood States rating scale [64,159]. Underlying confinement to a laboratory setting can have a negative impact on mood [49,160], which may confound findings in sleep studies lacking controls [69]. There is evidence to suggest that sleep deprivation may reset circadian clock gene abnormalities that contribute to depression [161].…”

Impact of Sleep Deprivation in the Neurological Intensive Care Unit: A Narrative Review

2019

View full text Add to dashboard Cite

Sleep is fundamental for everyday functioning, yet it is often negatively impacted in critically ill patients by the intensive care setting. With a focus on the neurological intensive care unit (NeuroICU), this narrative review summarizes methods of measuring sleep and addresses common causes of sleep disturbance in the hospital including environmental, pharmacological, and patient-related factors. The effects of sleep deprivation on the cardiovascular, pulmonary, immune, endocrine, and neuropsychological systems are discussed, with a focus on short-term deprivation in critically ill populations. Where evidence is lacking in the literature, long-term sleep deprivation studies and the effects of sleep deprivation in healthy individuals are also referenced. Lastly, strategies for the promotion of sleep in the NeuroICU are presented.

“…All participants stayed in a laboratory room of the Clinical Translational Research Center at the Hospital of the University of Pennsylvania, where they were continuously monitored by trained staff during the study. Participants arrived at the laboratory on the late afternoon of day 1 and were provided with a 9-hour time-in-bed (TIB) sleep opportunity, from 2130 to 0630 hours, to ensure that the participants obtained sufficient habitual sleep durations in the unfamiliar laboratory environment [26]. Participants in the TSD group were kept awake until 1830 hours on day 3, followed by a night of 12-hour recovery sleep on day 3 (from 1830 to 0630 hours).…”

Sleep deprivation enhances inter-stimulus interval effect on vigilant attention performance

Study Objective: Sleep deprivation significantly reduces the ability to maintain a consistent alertness level and impairs vigilant attention. Previous studies have shown that longer inter-stimulus interval (ISI) are associated with faster reaction times (RTs) on the Psychomotor Vigilance Test (PVT). However, whether and how sleep deprivation interacts with this ISI effect remains unclear. Methods: N = 70 healthy adults (age range 20-50 years, 41 males) participated in a 5-day and 4-night in-laboratory controlled sleep deprivation study, including N = 54 in the experimental group with one night of total sleep deprivation and N = 16 in the control group without sleep loss. All participants completed a neurobehavioral test battery every 2 hours while awake, including a 10-minute standard PVT (PVT-S, N = 1626) and a 3-minute brief PVT (PVT-B, N = 1622). The linear approach to threshold with ergodic rate (LATER) model was used to fit the RT data. Results: RT decreased significantly with longer ISI on the PVT-S and PVT-B. Increased ISI effect was found for both PVT-S and PVT-B during sleep deprivation compared to baseline or recovery sleep in the experimental group, whereas no differences in the ISI effect were found in the control group. The LATER model fitting indicated that changes in perceptual sensitivity rather than threshold adjustment may underlie the ISI effect. Conclusions: Both standard and brief PVT showed a similar ISI effect on vigilant attention performance. Sleep deprivation increased the ISI effect on both PVT-S and PVT-B, which may be due to impaired temporal resolution and time estimation after sleep loss.
