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

بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ In the Name of Allah, the Most Beneficent, the Most Merciful. عَمَّ يَتَسَاءَلُونَ - عَنِ النَّبَإِ الْعَظِيمِ - الَّذِي هُمْ فِيهِ مُخْتَلِفُونَ - كَلَّا سَيَعْلَمُونَ - ثُمَّ كَلَّا سَيَعْلَمُونَ - أَلَمْ نَجْعَلِ الْأَرْضَ مِهَادًا - وَالْجِبَالَ أَوْتَادًا - وَخَلَقْنَاكُمْ أَزْوَاجًا - وَجَعَلْنَا نَوْمَكُمْ سُبَاتًا - وَجَعَلْنَا اللَّيْلَ لِبَاسًا - وَجَعَلْنَا النَّهَارَ مَعَاشًا - وَبَنَيْنَا فَوْقَكُمْ سَبْعًا شِدَادًا - وَجَعَلْنَا سِرَاجًا وَهَّاجًا - وَأَنزَلْنَا مِنَ الْمُعْصِرَاتِ مَاءً ثَجَّاجًا - لِّنُخْرِجَ بِهِ حَبًّا وَنَبَاتًا - وَجَنَّاتٍ أَلْفَافًا (1. What are they asking about?)(2. About the great news,)(3. About which they are in disagreement.)(4. Nay, they will come to know!)(5. Nay, again, they will come to know!)(6. Have We not made the earth as a bed,)(7. And the mountains as pegs?)(8. And We have created you in pair

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 Jundab:The Prophet (ﷺ) became sick and did not get up (for Tahajjud prayer) for a night or two

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). Go and wake the sleeping lady occupants of these dwellings up (for prayers), perhaps a well dressed in this world may be naked in the Hereafter

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)

Mindfulness meditation for insomnia: A meta-analysis of randomized controlled trials.

Background: Insomnia is a widespread and debilitating condition that affects sleep quality and daily productivity. Although mindfulness meditation (MM) has been suggested as a potentially effective supplement to medical treatment for insomnia, no comprehensively quantitative research has been conducted in this field. Therefore, we performed a meta-analysis on the findings of related randomized controlled trials (RCTs) to evaluate the effects of MM on insomnia. Methods: Related publications in PubMed, EMBASE, the Cochrane Library and PsycINFO were searched up to July 2015. To calculate the standardized mean differences (SMDs) and 95% confidence intervals (CIs), we used a fixed effect model when heterogeneity was negligible and a random effect model when heterogeneity was significant. Results: A total of 330 participants in 6 RCTs that met the selection criteria were included in this meta-…

Cognitive Behavioral Therapy for Chronic Insomnia: A Systematic Review and Meta-analysis.

Background: Because psychological approaches are likely to produce sustained benefits without the risk for tolerance or adverse effects associated with pharmacologic approaches, cognitive behavioral therapy for insomnia (CBT-i) is now commonly recommended as first-line treatment for chronic insomnia. Purpose: To determine the efficacy of CBT-i on diary measures of overnight sleep in adults with chronic insomnia. Data sources: Searches of MEDLINE, EMBASE, PsycINFO, CINAHL, the Cochrane Library, and PubMed Clinical Queries from inception to 31 March 2015, supplemented with manual screening. Study selection: Randomized, controlled trials assessing the efficacy of face-to-face, multimodal CBT-i compared with inactive comparators on overnight sleep in adults with chronic insomnia. Studies of insomnia comorbid with medical, sleep, or psychiatric disorders were excluded. Data extraction: Study …

A meta-analysis of imagery rehearsal for post-trauma nightmares: effects on nightmare frequency, sleep quality, and posttraumatic stress.

This meta-analysis evaluates the efficacy of imagery rehearsal as a treatment for nightmares, general sleep disturbance, and symptoms of post-traumatic stress. Bibliographic databases and cited references were searched to identify clinical trials of imagery rehearsal in individuals with post-trauma nightmares. Thirteen studies met inclusion criteria and reported sleep and post-traumatic stress outcomes in sufficient detail to calculate effect sizes. Results indicate that imagery rehearsal had large effects on nightmare frequency, sleep quality, and PTSD symptoms from the initial to post-treatment assessments. These effects were sustained through 6 to 12 months follow-up. Furthermore, interventions that included both imagery rehearsal and cognitive behavioral therapy for insomnia resulted in greater treatment-related improvement in sleep quality than imagery rehearsal alone. Combined trea…

Cognitive-emotional hyperarousal as a premorbid characteristic of individuals vulnerable to insomnia.

Objective: To examine whether cognitive-emotional hyperarousal is a premorbid characteristic of middle-aged and young good sleepers vulnerable to stress-related insomnia. Methods: Self-reported information was collected from two samples of 305 middle-aged and 196 young adults. From those adults, 149 middle-aged (50.34 +/- 4.47 years) and 85 young (20.19 +/- 1.31 years) good sleepers were selected for the present study. The Ford Insomnia Response to Stress Test (FIRST) was used to measure vulnerability to stress-related insomnia. Trait measures of personality, arousability, rumination, presleep arousal, and coping skills were entered as predictors in the linear regression models, at the same time controlling for gender, depression, and anxiety. Results: The regression models showed that arousability (beta = 0.546), neuroticism (beta = 0.413), perceived stress (beta = 0.375), and ruminatio…

Regensburg Insomnia Scale (RIS): a new short rating scale for the assessment of psychological symptoms and sleep in insomnia; study design: development and validation of a new short self-rating scale in a sample of 218 patients suffering from insomnia and 94 healthy controls.

Background: The Regensburg Insomnia Scale (RIS) is a new self-rating scale to assess cognitive, emotional and behavioural aspects of psychophysiological insomnia (PI) with only ten items. A specific purpose of the new scale is the evaluation of the outcome of insomnia- specific cognitive behaviour therapy (CBT-I). Methods: Internal consistency of the RIS has been validated in 218 patients with PI. For determining sensitivity and specificity, this sample has been compared to 94 healthy controls. Sensitivity to change and pre-post cross-validation with the Pittsburgh Sleep Quality Index (PSQI) has been tested in a separate sample of 38 patients with PI undergoing CBT-I. Results: RIS distinguishes well between controls and patients with PI. Internal consistency was within a good range (Cronbach alpha = .890). RIS was sensitive for detecting improvements after CBT-I in sleep parameters and t…

Tired telomeres: Poor global sleep quality, perceived stress, and telomere length in immune cell subsets in obese men and women.

Poor sleep quality and short sleep duration are associated with increased incidence and progression of a number of chronic health conditions observed at greater frequency among the obese and those experiencing high levels of stress. Accelerated cellular aging, as indexed by telomere attrition in immune cells, is a plausible pathway linking sleep and disease risk. Prior studies linking sleep and telomere length are mixed. One factor may be reliance on leukocytes, which are composed of varied immune cell types, as the sole measure of telomere length. To better clarify these associations, we investigated the relationships of global sleep quality, measured by the Pittsburgh Sleep Quality Index (PSQI), and diary-reported sleep duration with telomere length in different immune cell subsets, including granulocytes, peripheral blood mononuclear cells (PBMCs), CD8+ and CD4+ T lymphocytes, and B l…

Adverse childhood experiences are associated with adult sleep disorders: a systematic review.

Adverse childhood experiences (ACEs) represent substantial threats to public health and affect about 58% of youth in the US. In addition to their acute effects such as injury and physical trauma, ACEs are associated with an increased risk of several negative health outcomes throughout the life course. Emerging evidence suggests that sleep disorders may be one such outcome, but existing studies have not been systematically reviewed and summarized. We conducted a systematic review to summarize the evidence concerning the relationship between ACEs and sleep disorders and disturbances, with a focus on adult women. Original publications were identified through searches of the electronic databases MEDLINE, Embase, and Web of Science using the keywords "childhood," "adversity," "abuse," and "sleep" as well as searches of the reference lists of eligible studies. Studies evaluating ACEs that occu…

Comparative effectiveness of three versions of a stepped care model for insomnia differing in the amount of therapist support in internet-delivered treatment: study protocol for a pragmatic cluster randomised controlled trial (GET Sleep).

Introduction: It is unclear how internet-delivered cognitive-behavioural therapy for insomnia (CBT-I) can be integrated into healthcare systems, and little is known about the optimal level of therapist guidance. The aim of this study is to investigate three different versions of a stepped care model for insomnia (IG1, IG2, IG3) versus treatment as usual (TAU). IG1, IG2 and IG3 rely on treatment by general practitioners (GPs) in the entry level and differ in the amount of guidance by e-coaches in internet-delivered CBT-I. Methods and analysis: In this randomised controlled trial, 4268 patients meeting International Classification of Diseases, Tenth Revision (ICD-10) criteria for insomnia will be recruited. The study will use cluster randomisation of GPs with an allocation ratio of 3:3:3:1 (IG1, IG2, IG3, TAU). In step 1 of the stepped care model, GPs will deliver psychoeducational treatme…

A randomised controlled trial of therapist-assisted online psychological therapies for posttraumatic stress disorder (STOP-PTSD): trial protocol.

Background: Over the last few decades, effective psychological treatments for posttraumatic stress disorder (PTSD) have been developed, but many patients are currently unable to access these treatments. There is initial evidence that therapist-assisted internet-based psychological treatments are effective for PTSD and may help increase access, but it remains unclear which of these treatments work best and are most acceptable to patients. This randomised controlled trial will compare a trauma-focussed and a nontrauma-focussed therapist-assisted cognitive behavioural Internet treatment for PTSD: Internet-delivered cognitive therapy for PTSD (iCT-PTSD) and internet-delivered stress management therapy (iStress-PTSD). Methods/design: The study is a single-blind, randomised controlled trial comparing iCT-PTSD, iStress-PTSD and a 13-week wait-list condition, with an embedded process study. Asse…

Light-enhanced cognitive behavioural therapy for sleep and fatigue: study protocol for a randomised controlled trial during chemotherapy for breast cancer.

Background: Women with breast cancer experience a significantly higher prevalence of sleep disturbance and insomnia than the general population. The experience of persistent sleep disturbance places these women at a higher risk of psychological and physical morbidity and a reduced quality of life. Treatment for sleep in this population is not part of routine care and is often managed inadequately. This randomised controlled trial will examine the combined effects of cognitive behavioural therapy (CBT) and bright light therapy (BLT) on the symptoms of insomnia, fatigue and mental health. Method/design: Women diagnosed with breast cancer who receive intravenous chemotherapy treatment at a quaternary referral metropolitan cancer centre in Melbourne, Australia, will be recruited. Recruitment will occur after diagnosis and prior to completion of chemotherapy. Eligible women will be randomised…

The effects of physical activity on cortisol and sleep: A systematic review and meta-analysis.

Background: Managing stress and having good quality sleep are inter-related factors that are essential for health, and both factors seem to be affected by physical activity. Although there is an established bidirectional relationship between stress and sleep, remarkably few studies have been designed to examine the effects of physical activity on cortisol, a key biomarker for stress, and sleep. Research is particularly scarce in older people despite both sleep and cortisol changing with age. This systematic literature review addresses this gap. Methods: A systematic review was conducted following the PRISMA guidelines. Original, peer-reviewed records of intervention studies such as randomized controlled trials (RCTs) and non-RCTs with relevant control groups were eligible for inclusion. The Participant, Intervention, Comparison, Outcome (PICO) characteristics were (1) adults or older adu…

Reducing bedtime physiological arousal levels using immersive audio-visual respiratory bio-feedback: a pilot study in women with insomnia symptoms.

Hyperarousal is a critical component of insomnia, particularly at bedtime when individuals are trying to fall asleep. The current study evaluated the effect of a novel, acute behavioral experimental manipulation (combined immersive audio-visual relaxation and biofeedback) in reducing bedtime physiological hyperarousal in women with insomnia symptoms. After a clinical/adaptation polysomnographic (PSG) night, sixteen women with insomnia symptoms had two random-order PSG nights: immersive audio-visual respiratory bio-feedback across the falling asleep period (manipulation night), and no pre-sleep arousal manipulation (control night). While using immersive audio-visual respiratory bio-feedback, overall heart rate variability was increased and heart rate (HR) was reduced (by ~ 5 bpm; p < 0.01), reflecting downregulation of autonomic pre-sleep arousal, relative to no-manipulation. HR continued…

Socioeconomic status and sleep health: a narrative synthesis of 3 decades of empirical research.

Study objectives: This review aims to assess the association between socioeconomic status (SES) and sleep health in the general population and the mediating effects of lifestyle and mental and physical health in this relationship. Methods: Observational studies testing the independent association between objective or subjective SES indicators and behavioral/physiological or clinical sleep health variables in the general population were included. PubMed/MEDLINE was searched for reports published from January 1990 to December 2019. The direction of effect was used as the primary effect measure, testing the hypothesis that low SES is associated with poor sleep health outcomes. Results are presented in the form of direction effect plots and synthesized as binomial proportions. Results: Overall, 336 studies were identified. A high proportion of effects at the expected direction was noted for …

Predictors of sleep characteristics among women in southeast Texas.

Purpose: This study examined psychological and sociodemographic predictors of self-reported sleep characteristics including sleep duration, quality, and perceived adequacy of sleep among Hispanic and non-Hispanic women of low socioeconomic status. Method: Cross-sectional survey data were analyzed from 2,670 women ages 18 to 55 (74% Hispanic, 18% non-Hispanic White, 8% non-Hispanic Black) participating in a cancer prevention study in southeast Texas. Results: Women reported sleeping 7.1 hours per night on average; however, nearly 45% were short (≤6; 35.3%) or long (≥9; 9.5%) sleepers. Sleep quality was rated less than "good" for 43.7% of the total sample, and 22.5% reported adequate sleep "none" or "a little" of the time. Multivariable analyses identified different demographic and psychological predictors for the sleep characteristics; decreased sleep adequacy was associated with parity, …

Intrinsic circadian period of sighted patients with circadian rhythm sleep disorder, free-running type.

Background: Circadian rhythm sleep disorder, free-running type (FRT), is an intractable sleep disorder in which sleep and wake times progressively delay each day even in normal living environments. This disorder severely affects the social functioning of patients because of periodic nighttime insomnia, excessive daytime sleepiness, and a high rate of comorbid psychiatric disorders. Although abnormal regulation of the biological clock is suspected, the pathophysiology of FRT has yet to be elucidated. In this study, the endogenous circadian period, τ, of FRT patients with normal vision was compared with that of healthy individuals whose circadian rhythms are entrained to a 24-hour cycle. Methods: Six FRT patients and 17 healthy individuals (9 intermediate chronotypes and 8 evening chronotypes) were subjected to a 7-day, 28-hour sleep-wake schedule according to the forced desynchrony protoc…

How sleep and wakefulness influence circadian rhythmicity: effects of insufficient and mistimed sleep on the animal and human transcriptome.

The mammalian circadian system is a multi-oscillator, hierarchically organised system where a central pacemaker synchronises behavioural, physiological and gene expression rhythms in peripheral tissues. Epidemiological studies show that disruption of this internal synchronisation by short sleep and shift work is associated with adverse health outcomes through mechanisms that remain to be elucidated. Here, we review recent animal and human studies demonstrating the profound effects of insufficient and mistimed sleep on the rhythms of gene expression in central and peripheral tissues. In mice, sleep restriction leads to an ~80% reduction in circadian transcripts in the brain and profound disruption of the liver transcriptome. In humans, sleep restriction leads to a 1.9% reduction in circadian transcripts in whole blood, and when sleep is displaced to the daytime, 97% of rhythmic genes beco…

Sleep, cognition, and normal aging: integrating a half century of multidisciplinary research.

Sleep is implicated in cognitive functioning in young adults. With increasing age, there are substantial changes to sleep quantity and quality, including changes to slow-wave sleep, spindle density, and sleep continuity/fragmentation. A provocative question for the field of cognitive aging is whether such changes in sleep physiology affect cognition (e.g., memory consolidation). We review nearly a half century of research across seven diverse correlational and experimental domains that historically have had little crosstalk. Broadly speaking, sleep and cognitive functions are often related in advancing age, though the prevalence of null effects in healthy older adults (including correlations in the unexpected, negative direction) indicates that age may be an effect modifier of these associations. We interpret the literature as suggesting that maintaining good sleep quality, at least in y…

Depressed mood and repetitive negative thinking in Delayed Sleep-Wake Phase Disorder: Treatment effects and a comparison with good sleepers.

Circadian dysregulation and depressed mood commonly co-occur in young people, yet mechanisms linking Delayed Sleep-Wake Phase disorder (DSWPD) with depression are poorly understood. The present study aimed to examine the role of repetitive negative thinking (RNT), by comparing sleep, RNT and depressive symptomology between 40 'good' sleeping young people and 63 with DSWPD, with (n = 30) and without (n = 33) self-reported doctor-diagnosed depression. Secondary analysis from a randomised controlled trial was also undertaken to observe changes in depressive symptoms and RNT as a result of treatment for DSWPD. The 60 young people with DSWPD (mean [SD] age of 15.9 [2.2] years, 63% female) received either short (green) or long (red) wavelength bright light therapy (BLT) over 3 weeks. Cross-sectional baseline comparisons revealed an escalating pattern of worse sleep, more RNT and higher depress…

Influence of Exercise Time of Day on Salivary Melatonin Responses.

Background: Sleep deprivation negatively affects cognition, pain, mood, metabolism, and immunity, which can reduce athletic performance. Melatonin facilitates sleepiness and may be affected by the proximity of exercise to sleep. Purpose: To evaluate the influence of exercise time of day on salivary melatonin (s-melatonin) responses. Methods: Twelve regularly exercising men (age 20.75 [0.62] y, height 1.75 [0.04] m, mass 73.63 [10.43] kg, and maximal oxygen consumption 57.72 [6.11] mL/kg/min) participated in a randomized, crossover design. Subjects completed 3 protocols-morning exercise (09:00 h), afternoon exercise (16:00 h), and no exercise (CON)-at least 5 d apart. Exercise sessions consisted of 30 min of steady-state running at 75% of maximal oxygen consumption. Saliva was collected via passive drool at 20:00, 22:00, and 03:00 h following all sessions. Results: Repeated-measures analy…

Impact of sleep restriction versus idealized sleep on emotional experience, reactivity and regulation in healthy adolescents.

Sleep loss is associated with affective disturbances and disorders; however, there is limited understanding of specific mechanisms underlying these links, especially in adolescence. The current study tested the effects of sleep restriction versus idealized sleep on adolescents' emotional experience, reactivity and regulation (specifically cognitive reappraisal). Following 1 week of sleep monitoring, healthy adolescents (n = 42; ages 13-17 years) were randomized to 1 night of sleep restriction (4 h) or idealized sleep (9.5 h). The following day, adolescents provided self-reports of affect and anxiety and completed a laboratory-based task to assess: (1) emotional reactivity in response to positive, negative, and neutral images from the International Affective Picture System (IAPS); and (2) ability to use cognitive reappraisal to decrease negative emotional responses. Large effects were obs…
