“…Key changes are also observed during the N2 and N3 stages. Longer periods of RS result in a more similar proportion of time spent in sleep stages between normal sleep and RS [29]. Therefore, we speculate that individuals experienced increases in the proportion of SWS during RS, relative to the amount observed during normal sleep.…”

“…Interestingly, it is the intensity rather than the duration of sleep that in uences the recovery of function following SD. Sleep intensity during SWS is regarded as an indicator of homeostatic sleep stress [29,60]. After one night of SD, less than 10 h of RS can su ciently decrease the level of sleep stress to that observed at the end of a typical 8-h period of normal sleep [61,62].…”

“…Although two nights of RS can completely restore the global properties of the brain network, such RS does not appear to induce changes in local function [28]. Impairments in sleep structure following 58 h of wakefulness have also been shown to improve following 14 h of RS [29]. A recent study reported that a 90-min nap during a day of sleep deprivation can restore hippocampus-dependent learning, and that the structural composition of the hippocampus predicts the success of learning recovery [30].…”

Background: Considering the well-known detrimental effects of sleep deprivation (SD) on cognitive function and quality of life, sleep disturbances represent a major physical and mental health issue. Because working memory plays an important role in many complex cognitive processes, it is necessary to identify strategies that can effectively counteract the negative effects of SD on working memory. Methods: In the present study, we utilized event-related potentials (ERPs) to investigate the restorative effect of 8 h of recovery sleep (RS) on working memory impairments induced by 36 h of total sleep deprivation (TSD). We analyzed data from 16 healthy male participants. All participants completed a 2-back working memory task before and after 36 h of TSD and after 8 h of RS. Electroencephalography (EEG) data were recorded during the task. Results: N2 and P3 components related to working memory exhibited low-amplitude slow-wave characteristics following 36 h of TSD. Significant decreases in the latency of the N2 component were observed after 8 h of RS. RS also induced significant increases in the amplitude of the P3 component, along with significant decreases in P3 latency. Conclusions: Eight hours of RS also attenuated decreases in working memory performance caused by 36 h of TSD. However, the effects of RS appear to be limited.

“…, 2009). Regarding recovery, a recent international multi-collaborative study demonstrated the need for a minimum of 14 hours of continuous sleep to recover to a normal neurophysiological sleep pattern following 58h of sleep deprivation (Hennecke et al, 2019). If this does not occur, the damage increases proportionally.…”

Sleep deprivation is one of the most prevalent and widely used methods of psychological torture. Its effects on the body are without direct physical aggression and include significant somatic and psychological impacts and suffering. It is used in multiple coercive environments as a way, among other purposes, of degradation, debilitation, punishment or before and during the interrogation of detainees. In this specific context, it produces cognitive, emotional and physical exhaustion, with the aim of obtaining submission or compliance, and ultimately information or confession (Pérez-Sales, 2017; Reynolds & Banks, 2010; Sveaass, 2008). There is no universally accepted legal definition of what should be considered sleep deprivation in the context of torture. There are however converging positions from the legal and jurisprudential, and especially medical and psychiatric fields that allow for establishing sufficiently clear recommendations for the international community to take a reasoned stance. Within the framework of torture as defined in the United Nations Convention (UNCAT), intentionally forcing a person to have less than 6 hours of continuous, restful sleep must be considered a form of degrading treatment that could amount to cruel and inhuman treatment. We also suggest that when this daily sleep deprivation is intentionally prolonged in a sustained manner for three days or more, it should be considered as a form of torture in itself, irrespective of other coexisting or cumulative elements that may aggravate the condition.

Dear members of the ESRS, Dear readers of JSR, This third issue of JSR 2019 has a focus on the topics of sleep deprivation, sleep restriction and shift work. Apart from this, a variety of other topics are included, such as CNS hypersomnias, sleep following experimental manipulations, sleep and cognitive decline, PLMS and cardiovascular disease. Furthermore, single articles deal with the issues of chronotype and mental health, sleep rhythmic movements and napping. Eight new publications deal with different aspects of sleep deprivation, sleep restriction and shift work. Sleep deprivation is still a major experimental strategy to elucidate the functions of sleep. Hennecke et al. (2018) present an interesting experimental study investigating 17 young healthy men before and after 58 hr of wakefulness and during 14 hr of recovery sleep. Their main finding from their data analysis refers to individual sleep structure during baseline sleep and during 14 hr of recovery sleep. They conclude that sleep stage distribution after 58 hr of wakefulness and during 14 hr of recovery sleep resembles that of the baseline night, thus underlining the stability of individual sleep structure. Another study by Peretti et al. (2018) looked at the impact of sleep on aesthetic perception and empathy. In this study sleep-deprived and non-sleep-deprived subjects were compared with respect to several parameters of aesthetic perception and empathy.From their data analysis the authors conclude that sleep duration might mediate the relationship between empathy and aesthetic perception in the sleep group, with a stronger mediation effect of sleep on the emotional empathy measures. Unfortunately, in the sleep-deprived group there was a lack of correlation among empathy, aesthetic perception and sleep variables, which did not allow the required mediation analysis. It is concluded from the study that an adequate sleep duration may play an important role in stabilizing or improving cognitive and emotional empathic capabilities and the ability to make correct aesthetic judgements.A study from Finland (Härmä et al., 2018) investigated whether shift work with or without night work might be a risk factor for fatigue and short or long sleep. The data analysis was based on a prospective cohort study with 4-and 6-year follow-ups, the so-called Finnish Public Sector study. The main analysis aimed to estimate risk ratios of whether continuous exposure to shift work or changes between shift and day work might be associated with short or long sleep over 24 hr and fatigue at work and during free days. The authors were able to show that continuous shift work with night shifts did correlate with increased fatigue during free days and long sleep after a 6-year follow-up period. Exposure to shift work without night shifts had a less pronounced effect on sleep duration and no effect on fatigue. The conclusion is that irregular shift work including night shifts might be a modifiable risk factor for long sleep and increased fatigue, probably reflecting a higher need for...
