Interfering with theories of sleep and memory: sleep, declarative memory, and associative interference. 1In various studies, diagnosed insomnia is typically DSM-IV [266] Primary Insomnia, DSM-5 [44] Insomnia Disorder, International Classification of Sleep Disorders Second Edition (ICSD-2) [267] Psychophysiological Insomnia, or ICSD-3 Chronic Insomnia Disorder [268] all of which have similar criteria including difficulty initiating or maintaining sleep, daytime fatigue, malaise or dissatisfaction with sleep, duration of at least 3 months (1 month in DSM-IV) and symptom occurrence on 3 or more days per week. As with many trauma-related beliefs, we often are more critical of ourselves than we need to be. As noted above, there is strong evidence that REM sleep is important in the emotion-regulatory function of sleep. The ability to remember fear extinction is a key element of both normal recovery from trauma [118] and of psychotherapeutic treatment of PTSD using exposure therapy [7, 62, 101]. And because treatment of PTSD with exposure-based therapies relies upon formation and strengthening of extinction memory, the memory-enhancing function of healthy sleep may play a role in recovery and disturbed sleep in treatment resistance. If you or a loved one is suffering from these feelings, call 1-800-273-TALK (8255) or visit the nearest emergency room. Pace-Schott EF, Rubin Z, Verga PW, Spencer RMC, Orr SP, Milad MR. Chronotype, sleep quality and extinction memory, an actigraphic study. Whatever the cause, it can be extremely distressing to relive a nightmarish experience repeatedly, even as we try our best to get the memory out of our heads. Prospective prediction of posttraumatic stress disorder symptoms using fear potentiated auditory startle responses. Sleep promotes consolidation and generalization of extinction learning in simulated exposure therapy for spider fear. However, some car accident victims will confidential contact form. 2014;(Abstract Supplement)(in press). Within and between these stress systems, there are positive feedback mechanisms whereby neuroendocrine responses lead to elevated arousal and sleep disturbance that can, in turn, further activate stress responses. With time most people find that it becomes less painful to remember the trauma. Treatment of nightmares with prazosin: a systematic review. There are a variety of resources available to help deal with the aftermath of a traumatic experience. Predicting post-trauma stress symptoms from pre-trauma psychophysiologic reactivity, personality traits and measures of psychopathology. Craske MG, Kircanski K, Zelikowsky M, Mystkowski J, Chowdhury N, Baker A. Optimizing inhibitory learning during exposure therapy. Spoormaker VI, Schroter MS, Andrade KC, Dresler M, Kiem SA, Goya-Maldonado R, et al. Paradoxically, although CRF is elevated in the cerebrospinal fluid (CSF) of patients with PTSD [170172], abnormally low baseline levels of plasma cortisol are typically observed in this disorder [173], possibly due to downregulation of pituitary CRF receptors resulting from elevated CRF [174, 175]. be involved in at least four accidents throughout his or her lifetime. We reviewed evidence that stress responses and sleep disturbance can mutually exacerbate each other via neuroendocrine systems that also show abnormalities in PTSD, and that such abnormalities could potentially interfere with extinction learning and memory. ScienceDaily, 13 December 2016. For example, in the Sleep to Remember, Sleep to Forget model, Walker and colleagues suggest that REM sleep serves the dual purpose of consolidating the content of emotional memory and diminishing the memorys emotional charge [75, 10]. Rauch SL, Shin LM, Phelps EA. Sex differences in insomnia: a meta-analysis. Sex differences, gonadal hormones and the fear extinction network: implications for anxiety disorders. The neurobiology of sleep: genetics, cellular physiology and subcortical networks. A seven day actigraphy-based study of rumination and sleep disturbance among young adults with depressive symptoms. The exact ways in which REM sleep is altered in the period following a traumatic event, as well as after PTSD symptoms have developed, are not yet fully understood, and as noted above, a simple consistent quantitative change is not observed. This is because, in this activated behavioral state, the brain is closer to its threshold for awakening [213, 214]. Perhaps the most common emotional reaction to a trauma is feeling fearful and anxious. Fear and Anxiety. Dolan S, Martindale S, Robinson J, Kimbrel NA, Meyer EC, Kruse MI, et al.

Milad, Ph.D., is Associate Professor of Psychiatry at Massachusetts General Hospital and Harvard Medical School and Director of the Massachusetts General Hospital Behavioral Neuroscience Program. Exogenous CRF disrupts sleep [187], endogenous CRF promotes waking [188], and sleep deprivation elevates endogenous CRF [189].

Traumatic events can elicit many types of reactions, and each one is unique to the individual that experiences the trauma. 2). Perhaps the most common emotional reaction to a trauma is feeling fearful and anxious. Sleep disruption and repetitive nightmares meet DSM-5 PTSD criteria for alterations in arousal and reactivity and intrusion symptoms, respectively [1]. Get the help you need from a therapist near youa FREE service from Psychology Today. First, the sleep- and REM sleep-disruptive effects of experimental stressors appear with inescapable forms of stress, of which Pavlovian cued and contextual fear conditioning are canonical examples [157, 253] as, of course, are most traumatic events that precipitate PTSD in the human. Because symptoms can worsen over time, we suggest that continued sleep disturbances can also maintain and exacerbate PTSD. They may also develop other symptoms, such as nausea and vomiting Possible pathway whereby sleep disruption accompanying acute response to trauma can lead to PTSD. University of Zurich. More severe and persistent sleep disorders are usually seen in people with higher levels of post-traumatic stress and PTSD 15. Germain A, Buysse DJ, Shear MK, Fayyad R, Austin C. Clinical correlates of poor sleep quality in posttraumatic stress disorder. Specifically, amygdala connectivity with the insula, striatum, and thalamus was reduced, again suggesting dysfunction in emotion regulatory circuits. An H2(15)O PET study. A finding that longer sleep on the night preceding functional magnetic resonance imaging (fMRI) scans was positively associated with both resting-state amygdala-vmPFC functional connectivity and higher self-report indices of mental health indicates that even mild restriction of sleep can diminish vmPFC-amygdala connectivity [154]. Schiller D, Monfils MH, Raio CM, Johnson DC, Ledoux JE, Phelps EA. Talking to a licensed professional can help with these side effects and can help the victim process what has happened to them. Eglinton R, Chung MC. all injured accident victims and can help you choose the legal path that is 2015;Apr 20. Deficient memory for extinction has been shown to differentiate individuals with PTSD from trauma-exposed controls at both the behavioral and neural levels [8890]. Glover EM, Phifer JE, Crain DF, Norrholm SD, Davis M, Bradley B, et al. Our studies suggest that insomnia patients show hyperactivation of the dACC and hypoactivation of the vmPFC during REM sleep. It is important to note that, in addition to effects of sleep on amygdala-vmPFC connectivity, trauma itself may affect such circuits, as is suggested by reports of structural abnormalities in these areas in PTSD [116, 120]. About sleeps role in memory. 18. Aguilera G. HPA axis responsiveness to stress: implications for healthy aging. Extinction learning before trauma and subsequent posttraumatic stress. Ellenbogen JM, Hulbert JC, Stickgold R, Dinges DF, Thompson-Schill SL. Liberzon I, Krstov M, Young EA. Stress and multiple memory systems: from thinking to doing. Louie K, Wilson MA. Harvey AG, Talbot LS, Gershon A. In the lab, the researchers showed test subjects a traumatic video. Edward F. Pace-Schott, Anne Germain, and Mohammed R. Milad. Heres what we reveal when we speak, whether we mean to or not. We are experimenting with display styles that make it easier to read articles in PMC. Involvement of sleep disturbance in the pathophysiology of PTSD does not, of course, exclude the more traditional view that psychiatric illness produces unique sleep disturbances or exacerbates pre-existing ones. 1) encompass these same networks that show structural and functional abnormalities in PTSD. A flashback occurs when the trauma memory gets cued and makes it feel as if the trauma is happening all over again. Note, however, that typically in exposure therapy, within-session extinction/habituation is continued following each session in the form of exposure homework (e.g., [103, 112]); therefore, the encoding and consolidation of extinction/habituation is, in reality, an iterative process. PTSD can last for as little as a few months or can become a chronic condition that victims live with for the rest of their lives. Feige B, Al-Shajlawi A, Nissen C, Voderholzer U, Hornyak M, Spiegelhalder K, et al. Sleep disturbance predating or acutely resulting from a traumatic event, particularly if it develops into chronic insomnia, may initiate positive feedback and allostatic mechanisms that impair emotional regulation and promote the pathophysiology of PTSD. While these reactions are common, most people will find that they gradually subside over a period of days to months. Deliens G, Schmitz R, Caudron I, Mary A, Leproult R, Peigneux P. Does recall after sleep-dependent memory consolidation reinstate sensitivity to retroactive interference? CSF norepinephrine concentrations in posttraumatic stress disorder. The dashed line depicts an additional positive feedback mechanism whereby poor extinction memory promotes continued activation of neuroendocrine stress systems by failing to inhibit expression of conditioned fears. Summary: If we sleep in the first 24 hours after a traumatic experience, this may help process and integrate the distressing memories more . These include, but are not limited to: Did you know that 70% of American adults have experienced trauma at some point during their lives? But, for some people, the symptoms of trauma may be extremely severe and can also last longer. Posttraumatic stress disorder may be associated with impaired fear inhibition: relation to symptom severity. This means restorative sleep and REM are often limited. In light of the preceding findings, we suggest that alterations in the emotion regulatory functions of sleep might be one such factor. lucky to have escaped without injury. A population-based study of associations between current posttraumatic stress symptoms and current fatigue. PTSD in children and teenagers is a little more difficult to diagnose, and the signs and symptoms are different than those of an adult suffering from PTSD. You may find yourself jumpier than usual, or taking longer to come back to your baseline. representing injured car accident victims. Tools for translational neuroscience: PTSD is associated with heightened fear responses using acoustic startle but not skin conductance measures. However, to what extent can sleep disturbance predating or acutely following trauma itself initiate these pathogenic events? Trauma reactivation under the influence of propranolol decreases posttraumatic stress symptoms and disorder: 3 open-label trials. Trauma can affect anyone, directly or indirectly. Vervliet B, Craske MG, Hermans D. Fear extinction and relapse: state of the art. Effects of sleep on memory for conditioned fear and fear extinction. Mellman TA, David D, Kulick-Bell R, Hebding J, Nolan B. We might feel anger at the person or situation responsible for our trauma. Evidence that PTSD may influence the quality versus absolute quantity of REM includes not only greater REM density [134], but the fact that some studies have shown greater percent REM in PTSD [140, 139]. Payne JD, Chambers AM, Kensinger EA. Heim C, Nemeroff CB. Because these effects did not differentiate control groups exposed and tested entirely in the morning or evening, a time-of-day explanation was ruled out. Bremner JD, Licinio J, Darnell A, Krystal JH, Owens MJ, Southwick SM, et al. Questions? symptoms associated with traumatic brain injuries. The research was supported by MH101567, MH090357, USAMRAA Log11293006, and MH097965. Landmann N, Kuhn M, Piosczyk H, Feige B, Baglioni C, Spiegelhalder K, et al. no signs of physical trauma. In turn, increased NE can stimulate the PVN resulting in further CRF release and activation of the HPA and central stress responses [184, 186]. Maquet P, Ruby P, Maudoux A, Albouy G, Sterpenich V, Dang-Vu T, et al. Therefore, the persistence of conditioned fear, in the face of its failed extinction (dashed line in Fig. Zalta AK, Dowd S, Rosenfield D, Smits JA, Otto MW, Simon NM et al. Importantly, this percentage increased by only about 9% when a more liberal (subsyndromal) definition of ASD, not requiring dissociative symptoms, was used [46]. Other sleep disturbances, such as insomnia can It is a good reason why you should seek professional help. McSweeney FK, Swindell S. Common processes may contribute to extinction and habituation. Experimental evidence for many specific, Comparison of REM activations in individuals with insomnia versus without insomnia. As discussed below, chronic hyperarousal is increasingly implicated in the development of insomnia [3742]. Zeidan MA, Igoe SA, Linnman C, Vitalo A, Levine JB, Klibanski A, et al. Wessa M, Flor H. Failure of extinction of fear responses in posttraumatic stress disorder: evidence from second-order conditioning. Replaying the Memory. Nonetheless, other studies do suggest greater de novo fear conditioning in PTSD [92] and deficient acquisition of extinction [9395]. So what are some of the common reactions to a traumatic event? Sleep disturbance and its relationship to psychiatric morbidity after Hurricane Andrew. Second, in a study of over 1000 traumatic injury survivors, only about a third of persons who developed PTSD by 1year following a traumatic event showed ASD immediately following the trauma [46]. As such, car accident survivors who suffer from depression Therefore, to preserve REM sleep following a trauma, optimizing overall sleep quality by treating comorbid insomnia or other sleep disorders and improving sleep hygiene is important. Family When this occurs, you It's going to be turned up for a while, alert for the possibility of further danger. Neurocircuitry models of posttraumatic stress disorder and extinction: human neuroimaging researchpast, present, and future. However, in a comparison of two different groups, the insomnia group showed lesser increase in the vmPFC, an area associated with the memory and expression of fear extinction (b), Sleep and REM sleep disturbance in the pathophysiology of PTSD: the role of extinction memory. Grillon C. D-cycloserine facilitation of fear extinction and exposure-based therapy might rely on lower-level, automatic mechanisms. For objective sleep measures, a recent meta-analysis [134] found that, among the highly variable alterations of sleep in PTSD compared to control groups, increased stage 1 NREM sleep, decreased slow wave sleep (SWS) (see also [139]), and increased average number of rapid eye movements per minute in REM sleep (REM sleep density) were the most consistent abnormalities across studies. Similarly, if an individual has poor sleep quality due to a pre-existing sleep disorder (such as obstructive sleep apnea) or is experiencing poor sleep due to limited sleep opportunity or sleep during an unfavorable circadian phase (as is common in the military), these same factors may increase vulnerability to PTSD irrespective of formal insomnia diagnoses. Temporally structured replay of awake hippocampal ensemble activity during rapid eye movement sleep. Therefore, lesser capacity to acquire extinction, possibly due, in part, to enhanced ability to acquire a conditioned fear that is itself related to augmented autonomic and limbic reactivity may also play a role, particularly in the hyperarousal symptoms of PTSD. These abnormalities are consistent with an underlying hyperarousal in PTSD that lightens sleep, prevents deeper, more restorative sleep stages, and alters the distinct physiology of REM sleep [20, 29, 36, 134, 143]. A good place to start is your primary care provider they will be able to refer you to a licensed mental health professional that specializes in trauma. Vanderheyden WM, Poe GR, Liberzon I. Trauma exposure and sleep: using a rodent model to understand sleep function in PTSD. Similarly, the interactions of extinction learning and memory with time-of-day [254] as well as sleep quality and chronotype [255, 256] described in healthy subjects (reviewed in ref. Blaming Yourself for the Trauma. I also want to note that not all post-traumatic reactions are bad. In addition to its effect on the HPA axis, CRF from the PVN as well as from the central nucleus of the amygdala (CeA) is a key neuromodulator activating the central extrahypothalamic stress system via CRF1 receptors in the CeA, basolateral nucleus of the amygdala (BLA), bed nucleus of the stria terminalis (BNST), and locus coerulus (LC) [178, 179]. Chronic sleep disruption can subsequently perpetuate PTSD symptoms by continued interference with normal processing of emotional memories as well as impaired consolidation of therapeutic extinction memories if exposure therapy has been initiated. Amygdala, medial prefrontal cortex, and hippocampal function in PTSD. Interestingly, such hyperarousal also produces sleep disturbance that, in turn, may further disrupt sleep-dependent memory processes as detailed below. Levin R, Nielsen TA. A systematic review assessing bidirectionality between sleep disturbances, anxiety, and depression. For example, among 99 studies on diverse disasters, the prevalence of PTSD at first assessment averaged 27% [150]. Critical periods requiring sleep, including specifically REM sleep, for memory consolidation following encoding have been demonstrated in animals and humans [85], and such a period for extinction memory has recently been demonstrated for REM sleep [86]. Norberg MM, Krystal JH, Tolin DF. Milad MR, Orr SP, Lasko NB, Chang Y, Rauch SL, Pitman RK. Spoormaker VI, Sturm A, Andrade KC, Schroter MS, Goya-Maldonado R, et al. Neurobiological basis of failure to recall extinction memory in posttraumatic stress disorder. While daytime affective symptoms and associated neural, physiological, and endocrine disturbances can adversely affect sleep, there is growing evidence that sleep disturbances (e.g., insomnia) can reciprocally impact daytime symptoms. Parsons RG, Ressler KJ. An opportunity for prevention? This review explores the possibility that disruption of sleep by acute or chronic stress may lead to alterations in emotional memory processing and, thereby, contribute to psychiatric illnesses such as post-traumatic stress disorder (PTSD) [1]. 1). However, a more general emotional dysregulation is a characteristic of many individuals with insomnia [206] that can be reflected in personality variables [207] such as a tendency to internalize conflict [208] as well as by the high comorbidity of insomnia with mood and anxiety disorders [22, 32, 200, 209]. Exposure therapy for social anxiety disorder. Fourth, although delayed-onset PTSD, defined most strictly as onset of any PTSD symptoms only after 6months or more following trauma, is controversial and rare [49, 50], exacerbation of existing symptoms is common [49]. Yehuda R. Status of glucocorticoid alterations in post-traumatic stress disorder. Many people go through strong emotional or physical reactions immediately after they go through any traumatic event. In most car accident victims, these Because of the drain on your body due to the emotions involved, you will feel exhausted, and some will feel tired and emotionally drained because of the fight or flight response they seem to be going through so much of the time. Polysomnographically measured sleep abnormalities in PTSD: a meta-analytic review. Temporal relations between sleep problems and both traumatic event exposure and PTSD: a critical review of the empirical literature. Guilt. Clin Psychol Publication Division Clinical Psychol Am Psychol Assoc. Nofzinger EA, Mintun MA, Wiseman M, Kupfer DJ, Moore RY. The underlying changes in REM sleep in PTSD thus remain areas in need of additional study. While the actual experience probably felt like a nightmare, it's common for real nightmares to haunt our dreams in the aftermath of a trauma. Conversely, sleep disturbance is both a common behavioral sequela of acute and chronic stress [11, 12] and a prominent symptom of anxiety and mood disorders [13, 14]. On the other hand, it also helps contextualize the recollections, process them informationally and store these memories. All the same, it's a common response after a trauma. A deficit in the ability to encode, consolidate, or retrieve extinction memory is believed to play a role in the development and perpetuation of such disorders [6, 59, 61, 87]. Koren D, Arnon I, Lavie P, Klein E. Sleep complaints as early predictors of posttraumatic stress disorder: a 1-year prospective study of injured survivors of motor vehicle accidents. Finally, future studies might also examine the effects of sleep on the newly described phenomenon of fear erasure using reconsolidation blockade following retrieval of traumatic memory [2, 57, 259261]. Schiller D, Delgado MR. Overlapping neural systems mediating extinction, reversal and regulation of fear. Unfortunately, Certain sounds, sights, or smells may trigger a flashback to the traumatic event, causing the person to react as though it was happening again. As noted, these fear-related structures are hyperactive and extinction-related areas hypoactive in PTSD [88, 130]. Therefore . Stepanski EJ, Rybarczyk B. Herry C, Ferraguti F, Singewald N, Letzkus JJ, Ehrlich I, Luthi A. Neuronal circuits of fear extinction. We may be angry at ourselves if we blame ourselves for what happened. Difficulty Sleeping. Caveats to animal models of physiological sleep disturbance and PTSD need also be emphasized. For clarity, the following mechanisms mentioned in the text are not depicted: 1) interaction between sympathetic activation and the HPA axis, 2) possible negative feedback mechanisms involving hypothalamic corticotropin releasing factor (CRF) that may explain hypocortisolemia in PTSD, and 3) direct effects of stress systems on extinction memory and habituation. It is especially important to promote the generalization of extinction memories acquired during exposure sessions to prevent the return of fear outside of the safe, therapeutic context [3, 62, 64, 107110]. While many trauma victims will experience initial anxiety and fearfulness post-trauma, many will recover from those feelings and go back to their daily routines with a sense of normalcy. Harvey AG. Similarly, this region includes the ventromedial prefrontal and hippocampal areas [127129] linked to a putative extinction memory network [61]. Symptoms typically appear within three months of the event, and are severe enough to interfere with relationships and daily activities. Pillai V, Steenburg LA, Ciesla JA, Roth T, Drake CL. Extinction is a form of emotional memory that is important to normal emotion regulation [2], influenced by normal sleep and its disturbance [35], impaired in anxiety disorders [6], and exploited in their treatment [7]. 3), may continue to activate stress systems and further exacerbate positive feedback mechanisms that lead to further impairment of extinction and the persistence of pathological fear. Financial support for ScienceDaily comes from advertisements and referral programs, where indicated. Remember, feelings of anxiety, confusion, anger, and guilt are all natural following a trauma. Killgore WD. Presence and acquired origin of reduced recall for fear extinction in PTSD: results of a twin study. They may often express their feelings through play, reliving their traumatic experiences through their toys, rather than talking about their thoughts and feelings. Directly affected people are those who experienced the traumatic event first-hand. The initiating factor of the HPA response is corticotropin-releasing factor (CRF), a polypeptide neurohormone whose secretion by the paraventricular nucleus (PVN) of the hypothalamus triggers release of adrenocorticotropic hormone (ACTH) from the anterior pituitary leading to the secretion of adrenal glucocorticoids [169]. Yehuda R. Advances in understanding neuroendocrine alterations in PTSD and their therapeutic implications. 3, following a traumatic stressor, such interactions may disrupt sleep as well as sleep-mediated processing of extinction memory producing an escalating abnormality potentially leading to PTSD. Ones sex, sleep, and posttraumatic stress disorder. Sex differences in objective measures of sleep in post-traumatic stress disorder and healthy control subjects. Mellman TA, Pigeon WR, Nowell PD, Nolan B. Seeing Danger Everywhere. Prog Neuropsychopharmacol Biol Psychiatry. | Milad MR, Igoe SA, Lebron-Milad K, Novales JE. "This supports the assumption that sleep may have a protective effect in the aftermath of traumatic experiences.". Corticotropin-releasing factor (CRF) in stress and disease: a review of literature and treatment perspectives with special emphasis on psychiatric disorders. The emotional aftermath of a car accident is Posttraumatic stress disorder associated with combat service in Iraq or Afghanistan: reconciling prevalence differences between studies. For example, following a traumatic event, females who progressed to PTSD showed greater wake time after sleep onset than males who similarly developed PTSD [231]. 7. Memory consolidation processes also provide opportunity for extinction/habituation to generalize, and sleep appears to augment this process as well [3, 107]. 19. However, there are some people who will continue to have those feelings and flashbacks to the traumatic event, and develop disorders stemming from those feelings. Baglioni C, Spiegelhalder K, Lombardo C, Riemann D. Sleep and emotions: a focus on insomnia. We suggest that optimizing sleep quality following trauma, and even strategically timing sleep to strengthen extinction memories therapeutically instantiated during exposure therapy, may allow sleep itself to be recruited in the treatment of PTSD and other trauma and stress-related disorders. Epidemiologic study of sleep disturbances and psychiatric disorders. Cartwright R, Luten A, Young M, Mercer P, Bears M. Role of REM sleep and dream affect in overnight mood regulation: a study of normal volunteers. The gold standard treatment for certain disorders with abnormal levels of anxiety involves formation of therapeutic extinction using exposure therapy [7, 62]. 4. Recent research, published in Neurology, Sleep changes in the disorder of insomnia: a meta-analysis of polysomnographic studies. Plendl W, Wotjak CT. Dissociation of within- and between-session extinction of conditioned fear. According to the American Psychological Association, victims of trauma may experience feelings of shock and denial immediately following the event. Although CRF triggers release of cortisol via ACTH and PTSD may be characterized by low peripheral (plasma) levels of cortisol, variations in levels of central CRF and plasma cortisol are dissociable. 16. Print and share this post if it might help your discussion. It is also, however, important to recognize that extinction is a process that is ongoing in the course of everyday life. ScienceDaily. We often will feel sad and cry after a highly traumatic event. Sign up for our Better Heath Care Newsletter (for tips on getting the best medical care for you and your family), 1310 L Street NWSuite 800 They are characterized by a constant feeling of anxiety and fear, which . Loss of Interest in Sex. As with sleep, the brain may be inclined to avoid sexual activity following a trauma. In fact, like so many of these reactions, it's a sign that our nervous system is functioning as it should. It's normal for these feelings of sadness to wax and wane. Content on this website is for information only. Pretreatment REM sleep and subjective sleep quality distinguish depressed psychotherapy remitters and nonremitters. For example, in the rat, fear conditioning and other forms of inescapable stress lead to disruption of sleep and fragmentation of REM sleep, conditioned reminders produce similar sleep-disruptive effects for several weeks post conditioning, and extinction training reverses these sleep effects (reviewed in ref.
