Sleep and insomnia النوم

وَهُوَ ٱلَّذِي جَعَلَ لَكُمُ ٱلَّيۡلَ لِبَاسࣰ ا وَٱلنَّوۡمَ سُبَاتࣰ ا وَجَعَلَ ٱلنَّهَارَ نُشُورࣰ ا

It is He who made the night a garment for you, and sleep a rest, and made the day like a resurrection

ٱللَّهُ لَآ إِلَٰهَ إِلَّا هُوَ ٱلۡحَيُّ ٱلۡقَيُّومُۚ لَا تَأۡخُذُهُۥ سِنَةࣱ وَلَا نَوۡمࣱۚ لَّهُۥ مَا فِي ٱلسَّمَٰوَٰتِ وَمَا فِي ٱلۡأَرۡضِۗ مَن ذَا ٱلَّذِي يَشۡفَعُ عِندَهُۥٓ إِلَّا بِإِذۡنِهِۦۚ يَعۡلَمُ مَا بَيۡنَ أَيۡدِيهِمۡ وَمَا خَلۡفَهُمۡۖ وَلَا يُحِيطُونَ بِشَيۡءࣲ مِّنۡ عِلۡمِهِۦٓ إِلَّا بِمَا شَآءَۚ وَسِعَ كُرۡسِيُّهُ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضَۖ وَلَا يَـُٔودُهُۥ حِفۡظُهُمَاۚ وَهُوَ ٱلۡعَلِيُّ ٱلۡعَظِيمُ

God: there is no god but Him, the Ever Living, the Ever Watchful.Neither slumber nor sleep overtakes Him. All that is in the heavens and in the earth belongs to Him. Who is there that can intercede with Him except by His leave? He knows what is before them and what is behind them, but they do not comprehend any of His knowledge except what He wills. His throne extends over the heavens and the earth; it does not weary Him to preserve them both. He is the Most High, the Tremendous

وَجَعَلۡنَا نَوۡمَكُمۡ سُبَاتࣰ ا

give you sleep for rest

ثُمَّ أَنزَلَ عَلَيۡكُم مِّنۢ بَعۡدِ ٱلۡغَمِّ أَمَنَةࣰ نُّعَاسࣰ ا يَغۡشَىٰ طَآئِفَةࣰ مِّنكُمۡۖ وَطَآئِفَةࣱ قَدۡ أَهَمَّتۡهُمۡ أَنفُسُهُمۡ يَظُنُّونَ بِٱللَّهِ غَيۡرَ ٱلۡحَقِّ ظَنَّ ٱلۡجَٰهِلِيَّةِۖ يَقُولُونَ هَل لَّنَا مِنَ ٱلۡأَمۡرِ مِن شَيۡءࣲۗ قُلۡ إِنَّ ٱلۡأَمۡرَ كُلَّهُۥ لِلَّهِۗ يُخۡفُونَ فِيٓ أَنفُسِهِم مَّا لَا يُبۡدُونَ لَكَۖ يَقُولُونَ لَوۡ كَانَ لَنَا مِنَ ٱلۡأَمۡرِ شَيۡءࣱ مَّا قُتِلۡنَا هَٰهُنَاۗ قُل لَّوۡ كُنتُمۡ فِي بُيُوتِكُمۡ لَبَرَزَ ٱلَّذِينَ كُتِبَ عَلَيۡهِمُ ٱلۡقَتۡلُ إِلَىٰ مَضَاجِعِهِمۡۖ وَلِيَبۡتَلِيَ ٱللَّهُ مَا فِي صُدُورِكُمۡ وَلِيُمَحِّصَ مَا فِي قُلُوبِكُمۡۚ وَٱللَّهُ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ

After sorrow, He caused calm to descend upon you, a sleep that overtook some of you. Another group, caring only for themselves, entertained false thoughts about God, thoughts more appropriate to pagan ignorance, and said, ‘Do we get a say in any of this?’ [Prophet], tell them, ‘Everything to do with this affair is in God’s hands.’ They conceal in their hearts things they will not reveal to you. They say, ‘If we had had our say in this, none of us would have been killed here.’ Tell them, ‘Even if you had resolved to stay at home, those who were destined to be killed would still have gone out to meet their deaths.’ God did this in order to test everything within you and in order to prove what is in your hearts. God knows your innermost thoughts very well

فَالِقُ ٱلۡإِصۡبَاحِ وَجَعَلَ ٱلَّيۡلَ سَكَنࣰ ا وَٱلشَّمۡسَ وَٱلۡقَمَرَ حُسۡبَانࣰ اۚ ذَٰلِكَ تَقۡدِيرُ ٱلۡعَزِيزِ ٱلۡعَلِيمِ

He makes the dawn break; He makes the night for rest; and He made the sun and the moon to a precise measure. That is the design of the Almighty, the All Knowing

إِذۡ يُغَشِّيكُمُ ٱلنُّعَاسَ أَمَنَةࣰ مِّنۡهُ وَيُنَزِّلُ عَلَيۡكُم مِّنَ ٱلسَّمَآءِ مَآءࣰ لِّيُطَهِّرَكُم بِهِۦ وَيُذۡهِبَ عَنكُمۡ رِجۡزَ ٱلشَّيۡطَٰنِ وَلِيَرۡبِطَ عَلَىٰ قُلُوبِكُمۡ وَيُثَبِّتَ بِهِ ٱلۡأَقۡدَامَ

Remember when He gave you sleep as a reassurance from Him, and sent down water from the sky to cleanse you, to remove Satan’s pollution from you, to make your hearts strong and your feet firm

And He it is Who made for you the night as a garment veiling you like a garment and sleep for repose rest for bodies through the temporary cessation of labour and He made the day for rising a time in which all rise to seek their livelihood and so on.

Have you not seen how your Lord spread the shadow. If He willed, He could have made it still – but We have made the sun its guide (45)Then We withdraw it towards Ourselves – a gradual withdrawal (46)And it is He Who makes the night a covering for you, and the sleep (as) a repose, and makes the day Nushur (47) Evidence of the Existence of the Creator and the Extent of His Power Here Allah begins explaining the evidence for His existence and His perfect power to create various things and pairs of opposites. Allah says: أَلَمْ تَرَ إِلَىٰ رَبِّكَ كَيْفَ مَدَّ الظِّلَّ (Have you not seen how your Lord spread the shadow.) Ibn 'Abbas, Ibn 'Umar, Abu Al-'Aliyah, Abu Malik, Masruq, Mujahid, Sa'id bin Jubayr, An-Nakha'i, Ad-Dahhak, Al-Hasan, Qatadah, As-Suddi and others said, "This refers to the period from the beginning of the dawn until the sun rises." وَلَوْ شَاءَ لَجَعَلَهُ سَاكِنًا (If

God there is no god that is there is none worthy of being worshipped in all existence except Him the Living the Everlasting the Eternal Sustainer the One constantly engaged in the management of His creation. Slumber does not seize Him neither sleep; to Him belongs all that is in the heavens and the earth as possessions creatures and servants; who is there that is to say none is there that shall intercede with Him save by His leave? in this for him. He knows what lies before them that is creation and what is after them of the affairs of this world and the Hereafter; and they encompass nothing of His knowledge that is they know nothing of what He knows save such as He wills to inform of it by way of His messengers. His throne subsumes the heavens and the earth it is said that His knowledge encompasses them both; it is also said that the kursī ‘throne’ itself subsumes them on account of its

and made your sleep for rest? repose for your bodies

Allah! None has the right to be worshipped but He, the Ever Living, the One Who sustains and protects all that exists. Neither slumber nor sleep overtakes Him. To Him belongs whatever is in the heavens and whatever is on the earth. Who is he that can intercede with Him except with His permission? He knows what happens to them (His creatures) in this world, and what will happen to them in the Hereafter. And they will never compass anything of His Knowledge except that which He wills. His Kursi extends over the heavens and the earth, and He feels no fatigue in guarding and preserving them. And He is the Most High, the Most Great (255) The Virtue of Ayat Al-Kursi This is Ayat Al-Kursi and tremendous virtues have been associated with it, for the authentic Hadith describes it as 'the greatest Ayah in the Book of Allah.' Imam Ahmad recorded that 'Ubayy bin Ka'b said that the Prophet ﷺ asked

Abu Hurairah narrated that the Messenger of Allah (s.a.w) said:"When time draws near, the dreams of a believer will hardly ever fail to come true, and the most truthful of them in dreams will be the truest in speech among them. The dream of a Muslim is a portion among the forty-six portions of Prophet-hood. And dreams are of three types: The righteous dream which is good news from Allah, dreams in which the Shaithan frightens someone, and dreams about something that has happened to the man himself. So when one of you sees what he dislikes, then he should get up and spit, and not tell any of the people- he said:- and I like the fetters in a dream while I dislike the iron collar." And the interpretation of fetters is being firm in the religion

Narrated Um Salama:One night the Prophet (ﷺ) got up and said, "Subhan Allah! How many afflictions Allah has revealed tonight and how many treasures have been sent down (disclosed).

Narrated Ibn Shihab:Once `Umar bin `Abdul `Aziz delayed the prayer and `Urwa bin Az-Zubair went to him and said, "Once in 'Iraq, Al-Mughira bin Shu`ba delayed his prayers and Abi Mas`ud Al-Ansari went to him and said, 'O Mughira! What is this? Don't you know that once Gabriel came and offered the prayer (Fajr prayer) and Allah's Messenger (ﷺ) prayed too, then he prayed again (Zuhr prayer) and so did Allah's Apostle and again he prayed (`Asr prayers and Allah's Messenger (ﷺ) did the same; again he prayed (Maghrib-prayer) and so did Allah's Messenger (ﷺ) and again prayed (`Isha prayer) and so did Allah's Apostle and (Gabriel) said, 'I was ordered to do so (to demonstrate the prayers prescribed to you)?'" `Umar (bin `Abdul `Aziz) said to `Urwa, "Be sure of what you Say. Did Gabriel lead Allah's Messenger (ﷺ) at the stated times of the prayers?" `Urwa replied, "Bashir bin Abi Mas`ud narrated like this on the authority of his father." `Urwa added, "Aisha told me that Allah's Messenger (ﷺ) used to pray `Asr prayer when the sunshine was still inside her residence (during the early time of `Asr)

Narrated Ibn `Abbas:"Once a delegation of `Abdul Qais came to Allah's Messenger (ﷺ) and said, "We belong to such and such branch of the tribe of Rabi'ah and we can only come to you in the sacred months. Order us to do something good so that we may take it from you and also invite to it those whom we have left behind (at home)." So he said, "I order you to do four things and forbid you from four things: To believe in Allah" - and then he explained it to them "to testify that none has the right to be worshipped but Allah and that I am Allah's Messenger (ﷺ), to establish the prayers (at the stated times), to pay the Zakat (obligatory charity), to hand me the Khumus (fifth) if you acquire spoils of war. And I forbid from (using) Dubba, Hantam, Muqaiyyar, and Naqir (all these were utensils used for the preparation of alcoholic drinks)

A sleep intervention study comparing effects of sleep restriction and fragmentation on sleep and vigilance and the need for recovery.: Purpose: Sleep deprivation is present not only in sleep disorders but also in numerous high demanding jobs and negatively affects cognition, performance and health. We developed a study design to distinguish the effects and need for recovery of two short-term disturbances - intermittent sleep fragmentation and partial sleep restriction. Methods: The randomized within-subjects design contained two weeks each with a baseline night, an intervention night of either sleep deprivation (5 h) or sleep f

The effect of group cognitive behavioural therapy for insomnia in postmenopausal women.: The menopausal period is associated with several complications in women. One of these complications is sleep disorders including insomnia disorder that can affect all aspects of personal life. The present study aimed to evaluate the effectiveness of cognitive behavioural therapy for insomnia (CBT-I) on insomnia severity and sleep quality among postmenopausal women. This was a randomised clinical trial in which 46 women were recruited and randomly allocated into two groups, one receiving CBT-I an

Investigating the subjective and objective efficacy of a cognitive behavioural therapy for insomnia (CBT-I)-based smartphone app on sleep: A randomised controlled trial.: Due to insufficient treatment options for insomnia, effective solutions are urgently needed. We evaluated the effects of a CBT-I-based app combining sleep training with subjective and objective sleep monitoring on (i) sleep and (ii) subjective-objective sleep discrepancies (SOSD). Fifty-seven volunteers (20-76 years; MAge = 45.67 ± 16.38; 39 female) suffering from sleep problems were randomly assigned to an experimental group (EG, n = 28) or a waitlist control group (CG, n = 29). During the 6-we

Let's talk about sleep: a systematic review of psychological interventions to improve sleep in college students.: Sleep problems are a common occurrence in college students. Insomnia, nightmares and impaired sleep quality lead to several mental health issues, as well as impaired academic performance. Although different sleep programmes exist, a systematic overview comparing their effectiveness is still missing. This systematic review aims to provide an overview of psychological interventions to improve sleep in college students. Seven databases were searched from November to December 2016 (MEDLINE, EMBASE,

The effects of a personalized sleep improvement app in subclinical poor sleepers: A randomized controlled trial.: The aim of this study was to determine the effects of a personalized smartphone application on subjective sleep quality, wellbeing and stress in participants with subclinical sleep problems. Healthy participants with subclinical threshold sleep issues that did not meet diagnostic criteria for insomnia were randomly assigned to use the app or be on a waiting list for app usage (control group). Subjective data on sleep quality (sleep quality component of Sleep Questionnaire B [primary endpoint] an

The effect of non-pharmacological sleep interventions on glycaemic measures in adults with sleep disturbances and behaviours: A systematic review and meta-analysis.: Background: Sleep insufficiency is known to negatively impact on glucose metabolism. Consequently, there is interest in determining the impact of improving sleep on glucose metabolism. We conducted a meta-analysis of studies that aimed at improving sleep using cognitive behavioural therapy for insomnia (CBT-I) and/or sleep hygiene or sleep extension on glucose metabolism. Methods: Searches were performed on MEDLINE, EMBASE, CINAHL and Cochrane. We included studies featuring adults≥18years, a sle

The effects of napping on cognitive function in preschoolers.

Objective: To determine the relationship between napping and cognitive function in preschool-aged children. Methods: Daytime napping, nighttime sleep, and cognitive function were assessed in 59 typically developing children aged 3 to 5 years, who were enrolled in full-time childcare. Participants wore an actigraphy watch for 7 days to measure sleep and napping patterns and completed neuropsychological testing emphasizing attention, response control, and vocabulary. Parents of participants completed behavior ratings and sleep logs during the study. Sleep/wake cycles were scored with the Sadeh algorithm. Results: Children who napped more on weekdays were also more likely to nap during weekends. Weekday napping and nighttime sleep were inversely correlated, such that those who napped more slept less at night, although total weekday sleep remained relatively constant. Weekday napping was sig…

Evidence for similarities between adolescents and parents in sleep patterns.

Objective: Sleep in adolescence may vary according to strain and environmental factors. In particular, parents' behavior may affect their children's psychological functioning and sleep. However, no data have been gathered with respect to parents and their adolescent children's concurrent sleep patterns. This was the aim of the present study, together with exploration of the possible influence of parenting style on adolescents' sleep. Methods: A total of 293 adolescents (mean age: 17.55; 214 females, 79 males) completed several questionnaires regarding their own psychological functioning as well as a sleep log for seven consecutive days. Additionally, adolescents rated parents' sleep and parenting styles. Results: Adolescents' and parents' sleep patterns proved to be correlated. Moreover, mother's sleep was related to adolescents' psychological functioning. However, SEM showed that mother…

Sleep after learning aids memory recall.

In recent years, the effect of sleep on memory consolidation has received considerable attention. In humans, these studies concentrated mainly on procedural types of memory, which are considered to be hippocampus-independent. Here, we show that sleep also has a persisting effect on hippocampus-dependent declarative memory. In two experiments, we examined high school students' ability to remember vocabulary. We show that declarative memory is enhanced when sleep follows within a few hours of learning, independent of time of day, and with equal amounts of interference during retention intervals. Sleep deprivation has a detrimental effect on memory, which was significant after a night of recovery sleep. Thus, fatigue accumulating during wake intervals could be ruled out as a confound.

Sleep-dependent motor memory plasticity in the human brain.

Growing evidence indicates a role for sleep in off-line memory processing, specifically in post-training consolidation. In humans, sleep has been shown to trigger overnight learning on a motor-sequence memory task, while equivalent waking periods produce no such improvement. But while the behavioral characteristics of sleep-dependent motor learning become increasingly well characterized, the underlying neural basis remains unknown. Here we present functional magnetic resonance imaging data demonstrating a change in the representation of a motor memory after a night of sleep. Subjects trained on a motor-skill memory and 12 hours later, after either sleep or wake, were retested during functional magnetic resonance imaging. Following sleep relative to wake, regions of increased activation were expressed in the right primary motor cortex, medial prefrontal lobe, hippocampus and left cerebell…

Motor memory consolidation in sleep shapes more effective neuronal representations.

Learning a motor skill involves a latent process of consolidation that develops after training to enhance the skill in the absence of any practice and crucially depends on sleep. Here, we show that this latent consolidation during sleep changes the brain representation of the motor skill by reducing overall the neocortical contributions to the representation. Functional magnetic resonance brain imaging was performed during initial training and 48 h later, at retesting, on a sequential finger movement task with training followed by either a night of regular sleep or sleep deprivation. An additional night of sleep for all subjects served to rule out unspecific effects of sleep loss at retrieval testing. Posttraining sleep, but not sleep deprivation, led to improved motor skill performance at retrieval. This sleep-dependent improvement was linked to greatly reduced brain activation in prefr…

Causal relationship between sleep traits and cognitive impairment: A Mendelian randomization study.

Objective: Observational studies had demonstrated a link between sleep disturbances and cognitive decline. Here, we aimed to investigate the causal association between genetically predicted sleep traits and cognitive impairment using Mendelian randomization (MR). Methods: Using strict criteria, we selected genetic variants from European ancestry Genome-wide association studies (GWAS) from the Sleep Disorders Knowledge Portal and UK Biobank as instrumental variables for several sleep traits, including insomnia, sleep duration, daytime sleepiness, daytime napping, and chronotype. Summary statistics related to cognitive impairment were derived from five different GWAS, including the Social Science Genetic Association Consortium. The role of self-reported sleep trait phenotypes in the etiology of cognitive impairment was explored using inverse-variance weighted (IVW) tests, MR-Egger tests, a…

The Insomnia Severity Index: psychometric indicators to detect insomnia cases and evaluate treatment response.

Background: Although insomnia is a prevalent complaint with significant morbidity, it often remains unrecognized and untreated. Brief and valid instruments are needed both for screening and outcome assessment. This study examined psychometric indices of the Insomnia Severity Index (ISI) to detect cases of insomnia in a population-based sample and to evaluate treatment response in a clinical sample. Methods: Participants were 959 individuals selected from the community for an epidemiological study of insomnia (Community sample) and 183 individuals evaluated for insomnia treatment and 62 controls without insomnia (Clinical sample). They completed the ISI and several measures of sleep quality, fatigue, psychological symptoms, and quality of life; those in the Clinical sample also completed sleep diaries, polysomnography, and interviews to validate their insomnia/good sleep status and assess…

Sleep timing and circadian phase in delayed sleep phase syndrome.

Delayed sleep phase syndrome (DSPS) is a circadian rhythm sleep disorder in which the timing of the sleep episode occurs later than desired and is associated with difficulty falling asleep, problems awakening on time (e.g., to meet work or school obligations), and daytime sleepiness. The phase relationship between the timing of sleep and endogenous circadian rhythms is critical to the initiation and maintenance of sleep, and significant alteration leads to impairment of sleep quality and duration. The aim of this retrospective study was to determine the phase relationship between sleep-wake times and physiological markers of circadian timing in clinic patients with DSPS. Objective and subjective measures of sleep timing and circadian phase markers (core body temperature and melatonin) were measured in patients with DSPS and compared with age-matched controls. As expected, significant del…

Shift work and the assessment and management of shift work disorder (SWD).

Nearly 20% of the labor force worldwide, work shifts that include work hours outside 07:00 h to 18:00 h. Shift work is common in many occupations that directly affect the health and safety of others (e.g., protective services, transportation, healthcare), whereas quality of life, health, and safety during shift work and the commute home can affect workers in any field. Increasing evidence indicates that shift-work schedules negatively influence worker physiology, health, and safety. Shift work disrupts circadian sleep and alerting cycles, resulting in disturbed daytime sleep and excessive sleepiness during the work shift. Moreover, shift workers are at risk for shift work disorder (SWD). This review focuses on shift work and the assessment and management of sleepiness and sleep disruption associated with shift work schedules and SWD. Management strategies include approaches to promote sl…

Melatonin as a Potential Adjuvant Treatment for COVID-19 beyond Sleep Disorders.

Melatonin is registered to treat circadian rhythm sleep-wake disorders and insomnia in patients aged 55 years and over. The essential role of the circadian sleep rhythm in the deterioration of sleep quality during COVID-19 confinement and the lack of an adverse effect of melatonin on respiratory drive indicate that melatonin has the potential to be a recommended treatment for sleep disturbances related to COVID-19. This review article describes the effects of melatonin additional to its sleep-related effects, which make this drug an attractive therapeutic option for treating patients with COVID-19. The preclinical data suggest that melatonin may inhibit COVID-19 progression. It may lower the risk of the entrance of the SARS-CoV-2 virus into cells, reduce uncontrolled hyper-inflammation and the activation of immune cells, limit the damage of tissues and multiorgan failure due to the actio…

Circadian rhythm disorders among adolescents: assessment and treatment options.

Delayed sleep phase disorder (DSPD) - a circadian rhythm sleep disorder - is most commonly seen in adolescents. The differential diagnosis between DSPD and conventional psychophysiological insomnia is important for correct therapeutic intervention. Adolescent DSPD sleep duration is commonly 9 hours or more. Depression may be comorbid with DSPD. DSPD has a negative impact on adolescent academic performance. DSPD treatments include bright light therapy, chronotherapeutic regimens, and administration of melatonin as a chronobiotic (as distinct from a soporific). Attention to non-photic and extrinsic factors including healthy sleep parameters is also important to enable better sleep and mood outcomes in adolescents.

Sleep-related problems in neurologic diseases.

There is a strong association between sleep-related problems and neurologic diseases. Neurologic diseases of the CNS can directly cause sleep problems when sleep-wake mechanisms associated with the ascending reticular activating system are involved. The major sleep disorders associated with neurologic problems are outlined in the International Classification of Sleep Disorders, 2nd edition, as hypersomnias of central origin, sleep-related breathing disorders, the insomnias, circadian rhythm sleep disorders, sleep-related movement disorders, parasomnias, and sleep-related epilepsy. In a patient with CNS disease and excessive sleepiness, sleep-related breathing disorders should be a first concern, given the known association between obstructive sleep apnea (OSA) and cerebrovascular disease and the potential confounding effects that OSA might have on an otherwise compromised ischemic CNS pe…

The treatments of chronic insomnia: a review of benzodiazepine receptor agonists and psychological and behavioral therapies.

The present review provides an assessment of the efficacy and safety of benzodiazepine receptor agonists (BZRAs) and psychological and behavioral interventions for insomnia. These methods include relaxation techniques, sleep hygiene rules, stimulus control, sleep restriction and cognitive techniques, often also referred to as cognitive-behavioral therapy (CBT) when encompassing cognitive strategies and at least one kind of behavioral intervention. In order to provide a comprehensive assessment of the literature regarding the efficacy and safety of these standard treatments for insomnia, an integrative synthesis of the existing meta-analytic studies for each of the various treatment modalities was conducted. Where meta-analytic studies were not available, data from double-blind placebo-controlled randomized controlled trials (RCTs) were included. The summary findings from this review are …

Does effective management of sleep disorders reduce cancer-related fatigue?

Cancer and cancer therapy are often associated with symptoms such as fatigue and sleep disturbances, before, during and after therapy. These symptoms of fatigue and poor sleep often occur in parallel having a significant impact on the physical functioning of patients with cancer. A strong correlation between cancer-related fatigue (CRF) and sleep has been observed in several studies, suggesting that they may be reciprocally related. The co-clustering of these symptoms suggests that they may have similar underlying aetiology and that treatments targeting either symptom may positively affect the other. Studies examining these clusters have shown that these symptoms often co-vary together. The potential mechanisms that link the relationship between insomnia and CRF are intriguing but require further investigation. Despite the high prevalence of insomnia and the often bidirectional relations…

Evidence-based psychological treatments for insomnia in older adults.

The review describes evidence-based psychological treatments (EBTs) for insomnia in older adults. Following coding procedures developed by the American Psychological Association's Committee on Science and Practice of the Society for Clinical Psychology, two treatments were found to meet EBT criteria: sleep restriction-sleep compression therapy and multicomponent cognitive-behavioral therapy. One additional treatment (stimulus control therapy) partially met criteria, but further corroborating studies are needed. At the present time, there is insufficient evidence to consider other psychological treatments, including cognitive therapy, relaxation, and sleep hygiene education, as stand-alone interventions beneficial for treating insomnia in older adults. Additional research is also needed to examine the efficacy of alternative-complementary therapies, such as bright light therapy, exercise,…

Therapeutic options for sleep-maintenance and sleep-onset insomnia.

Insomnia, defined as difficulty falling asleep, staying asleep, and/or experiencing restorative sleep with associated impairment or significant distress, is a common condition resulting in significant clinical and economic consequences. Many options are available to treat insomnia, to assist with either falling asleep (sleep onset) or maintaining sleep. We searched MEDLINE for articles published between January 1996 and January 2006, evaluated abstracts from recent professional meetings, and contacted the manufacturer of the most recent addition to the pharmacologic armamentarium for insomnia treatment (ramelteon) to gather information. Nonpharmacologic options include stimulus control, sleep hygiene education, sleep restriction, paradoxical intention, relaxation therapy, biofeedback, and cognitive behavioral therapy. Prescription and over-the-counter drug therapies include benzodiazepin…

Development and validation of the Japanese version of the Bedtime Procrastination Scale (BPS-J).

Background: The average sleep duration of Japanese people is shorter than that of people from other countries, and bedtime procrastination is suspected to be one of the factors contributing to this issue. This study aimed to develop and validate the Japanese version of the Bedtime Procrastination Scale (BPS-J). Methods: The BPS-J was developed through procedures including the translation and back-translation of the scale, cognitive interviews with 100 participants who reported having experiences of being diagnosed with insufficient sleep syndrome (ISS) or receiving treatment for ISS using open-ended online questionnaires, and expert checking. To investigate the scale's validity and reliability, an online survey was conducted with daytime workers aged 20 - 65 years without a history of sleep disorders other than ISS. Half the participants were retested using the same survey after 14 days.…

The role of financial strain in college students' work hours, sleep, and mental health.

Objective: To examine poor sleep quality as a potential mediator between college students' employment hours and depressive symptoms, and to examine if this mediation model might differ across students reporting different levels of financial strain. Participants: The sample was collected through a multi-site study during the Spring of 2019 and included 792 undergraduates (M = 20.1, SD = 1.9) in Upstate New York. Methods: Moderated mediation analyses based on cross-sectional self-report, online questionnaires. Results: Increased work hours predicted greater sleep disturbance, which, in turn, predicted more depressive symptoms. Compared to students in more comfortable financial situations, this mediation model only emerged for students reporting more financial strain and lower family socio-economic status. Conclusions: Student employment hours are a significant predictor of students' mental…

Coping, Cognitive Emotion Regulation, and Burnout in Long-Term Care Nursing Staff: A Preliminary Study.

Direct care workers (e.g., certified nursing assistants [CNAs]) employed in long-term care (LTC) are particularly vulnerable to the experience of burnout, yet they have received relatively less research attention compared to Licensed Practical Nurses and Registered Nurses. Within the burnout literature, evidence suggests that the deployment of certain coping strategies influences levels of burnout. The current study examined the extent to which coping (e.g., problem-focused, emotion-focused, and dysfunctional coping) and cognitive emotion regulation strategies (e.g., positive reappraisal) predicted burnout after controlling for covariates (age, sleep duration). Fifty-six CNAs were surveyed at four skilled nursing facilities in the United States. Dysfunctional coping was significantly associated with emotional exhaustion and depersonalization. Among cognitive emotion regulation strategies…

Sleep quality predicts positive and negative affect but not vice versa. An electronic diary study in depressed and healthy individuals.

Background: The exact nature of the complex relationship between sleep and affect has remained unclear. This study investigated the temporal order of change in sleep and affect in participants with and without depression. Methods: 27 depressed patients and 27 pair-matched healthy controls assessed their sleep in the morning and their affect 3 times a day for 30 consecutive days in their natural environment. Daily sleep quality and average positive affect (PA) and negative affect (NA) were used to examine whether changes in sleep quality preceded or followed changes in PA and NA, and whether this was different for patients and healthy controls. Second, presumptive mediating factors were investigated. We hypothesized that fatigue mediated the effect of changes in sleep quality on subsequent PA/NA, and that rumination mediated the effect of changes in PA/NA on subsequent sleep quality. Resu…

Sleep duration and risk for hypertension in women: results from the nurses' health study.

Background: Acute sleep restriction has been shown to increase blood pressure and sympathetic nervous system activity. Methods: We investigated the relationships between sleep duration and hypertension among women whose sleep durations were self-reported in 1986 (n = 82,130) and 2000 (n = 71,658) in the Nurses' Health Study I (NHS-I) and in 2001 (n = 84,674) in the Nurses' Health Study II (NHS-II). Results: After controlling for multiple risk factors in logistic regression models, the prevalence of hypertension was significantly higher among women in all 3 groups who slept ≤5 hours (odds ratio = 1.19, 95% confidence interval [CI] = 1.14-1.25) per night compared with 7 hours. In prospective analyses using Cox regression shorter sleep duration of ≤5 hours per night was significantly associated with a higher incidence of hypertension only in younger women (hazard ratio [HR] =1.20, 95% CI = …
