“…The confound was reduced in most of the PSG studies by disregarding data obtained during the first night of laboratory recording (eliminating “first night effects”) [23]. Interestingly, in a post-hoc assessment of studies that measured sleep objectively both at home and in the laboratory, the median difference between home and laboratory TST was only 3.2 min (Table 3).…”

Summary The common assumption that population sleep duration has declined in the past few decades has not been supported by recent reviews, which have been limited to self-reported data. The aim of this review was to assess whether there has been a reduction in objectively recorded sleep duration over the last 50+ years. The literature was searched for studies published from 1960–2013, which assessed objective sleep duration (TST) in healthy normal-sleeping adults. The search found 168 studies that met inclusion criteria, with 257 data points representing 6,052 individuals ages 18–88 years. Data were assessed by comparing the regression lines of age vs. TST in studies conducted between 1960–1989 vs. 1990–2013. Weighted regression analyses assessed the association of year of study with age-adjusted TST across all data points. Regression analyses also assessed the association of year of study with TST separately for 10-year age categories (e.g., ages 18–27 years), and separately for polysomnographic and actigraphic data, and for studies involving a fixed sleep schedule and participants’ customary sleep schedules. Analyses revealed no significant association of sleep duration with study year. The results are consistent with recent reviews of subjective data, which have challenged the notion of a modern epidemic of insufficient sleep.

Purpose of review Adolescence is a period of dynamic change in both sleep and emotional systems, with related increases in problems controlling emotion and behavior. Youth with anxiety enter adolescence with pre-existing vulnerabilities in systems of sleep and emotion that may place them at heightened risk. This review summarizes recent research on sleep and anxiety during the transition to adolescence, and highlights emerging themes. Recent findings Prospective studies support that sleep predicts anxiety symptoms in early adolescence. Notably, robust evidence for subjective sleep problems in anxious youth is not well-corroborated by objective assessments. Longitudinal designs and methodology that carefully examine dimensions of anxiety and sleep may clarify inconsistencies. Preliminary evidence suggests that late childhood to early adolescence may be a sensitive period for escalating problems with sleep and anxiety. Recent advances in the neuroscience of sleep can further refine integrative mechanistic models of developmental psychopathology—the role of sleep in emotional learning and memory is provided as an example. Summary Sleep problems are common and prospectively predict escalating anxiety symptoms. Precision is needed regarding the nature of sleep disruption, and how and when sleep impacts various aspects of developmental trajectories. This precision, along with advances in the neuroscience of sleep, may lead to developmentally-informed translational interventions.

“…Taken together, investigations of sleep pattern differences lack comparable designs; and there is no conclusive evidence for systematically impaired sleep patterns in those who suffer from nightmares, although robust findings of reduced self‐reported sleep quality do exist (Kis et al, ; Nielsen, Paquette, Solomonova, Lara‐Carrasco, Popova, & Levrier, ; Paul et al, ; Simor et al, ).…”

“…However, polysomnographic studies that investigated sleep architecture in nightmare sufferers revealed inhomogeneous results and were not able to explain the self-reported complaints. Significant differences in nightmare sufferers were presented by three studies; however, a systematic picture cannot be concluded from the altered parameters (which were less non-REM (NREM) and slow wave sleep, increased wakefulness after sleep onset, more periodic leg movements, reduced sleep efficiency, and higher sleep latency; Germain & Nielsen, 2003;Kis et al, 2014;Simor, Horvath, Gombos, Takacs, & Bodizs, 2012). After investigating cyclic alternating pattern-an unspecific marker of sleep microstructure (Parrino, Ferri, Bruni, & Terzano, 2012)-results showed more disturbed NREM sleep in nightmare sufferers compared to control participants (Simor, Bódizs, Horváth, & Ferri, 2013).…”

Nightmares do result in psychophysiological arousal: A multimeasure ambulatory assessment study

Individuals who frequently experience nightmares report compromised sleep quality, poor daytime mood, and functioning. Previous research has aimed at linking these impairments with altered sleep architecture, but results were inconclusive. One plausible explanation is that only a few studies recorded markers of autonomic nervous system activity. For the first time, this study collected such markers under ecologically valid conditions with ambulatory assessment. In 19 individuals with frequent nightmares (≥1 nightmare/week) and 19 healthy control participants (<1 nightmare/month), measures indicating autonomic activation (heart rate, heart rate variability, respiration cycle length, electrodermal fluctuations, EEG arousals, saliva cortisol, REM density) were collected while applying ambulatory polysomnographic assessment during 3 consecutive nights. When nightmare participants reported a nightmare, we analyzed the last 5 min of REM sleep before awakening and compared these data to their non‐nightmares as well as to the dream episodes of control participants. Overall, there were no general differences in autonomic activation of nightmare sufferers compared to control participants. However, when nightmare participants experienced nightmares, autonomic activation was markedly increased compared to their own non‐nightmares and, to some extent, to control participant’s dreams. Significant intraindividual differences were found for all autonomic measures except in participant’s EEG arousals and cortisol levels. Group differences were found in EEG arousals and heart rate. In conclusion, ambulatory polysomnography demonstrates that nightmares are accompanied by increased autonomic activation. Results support the notion of impaired self‐reported sleep quality caused by one’s autonomic response rather than altered sleep pattern.
