Possible side effects of nicotine.Detailed reference list is located on a separate image page. Nicotine reduces the amount of rapid eye movement (REM) sleep, slow-wave sleep (SWS), and total sleep time in healthy nonsmokers given nicotine via a transdermal patch, and the reduction is dose-dependent. Acute nicotine intoxication has been found to significantly reduce total sleep time and increase REM latency, sleep onset latency, and non-rapid eye movement (NREM) stage 2 sleep time.

Laboratory based studies show that most women experience more disruption during night-time sleep and become sleepier. They sleep on average more during this time compared to pre-pregnancy sleep time. Total Sleep Time, however, decreases as the pregnancy progresses. Nocturia and Musculoskeletal discomfort account for the physiological factors impacting sleep during the first trimester.

One actigraphy study reports a modest decline in Total Sleep Time of 25 min in late-reproductive woman during the premenstrual week. The measurement of subjectively reported sleep during the menstrual cycle differs. Seventy percent of women report a negative impact on their sleep. Furthermore, they report a decrease in sleep quality on 2.5 days each month.

Nocturnal polyuria is defined as having more than 130% of the expected bladder capacity, which is specific for each age. Many children with nocturnal enuresis have altered nighttime secretion levels of antidiuretic hormone, which controls water retention in the body. This results in low antidiuretic hormone levels and excessive amounts of urine produced during sleep time.

SB-649868 is a dual orexin receptor antagonist in development by GlaxoSmithKline. The drug is currently in phase II development for insomnia. A phase I study evaluated doses up to 80 mg, resulting in significant improvement in sleep latency without adverse effects. In randomized, double- blind, placebo-controlled crossover trials, the 10 and 30 mg doses increased sleep time and reduced sleep latency.

Objectively, Slow Wave Sleep and Total Sleep Time as well as general sleep quality decreases further progressively during the third trimester. More night-time awakenings are common. Sleep Onset Latency problems and napping becomes more frequent. Physiological factors impacting sleep at this stage during the pregnancy are nocturia, fetal movement, uterine contractions, heartburn, orthopnea, leg cramps, rhinitis, nasal congestion, and sleeping position.

A 7.5 mg zopiclone tablet. Zopiclone is used for the short-term treatment of insomnia where sleep initiation or sleep maintenance are prominent symptoms. Long-term use is not recommended, as tolerance, dependence, and addiction can occur. One low-quality study found that zopiclone is ineffective in improving sleep quality or increasing sleep time in shift workers - more research in this area has been recommended.
|

Women at the third trimester report progressively reduced Total Sleep Time, and similarly to the second trimester, being uncomfortable, feeling fetal movements, heartburn, frequent urination, cramps and respiratory difficulties. The last weeks before delivery influence sleep quality reportedly most markedly. It is, however, curious that in spite of virtually all women experiencing poor sleep, only one third consider themselves to have current sleep problems.
|
|
Total Sleep Time is objectively the lowest during the 1 month postpartum, however, increasing normally steadily. Main contributing factors influencing sleep during the postpartum period are infant behaviours such as infant sleep and feeding patterns, bed-sharing and infant temperament. It appears that Slow Wave Sleep is preserved during the first weeks postpartum in spite and because of chronic sleep deprivation. Frequent napping occurs.

The average sleep time of a captive house mouse is reported to be 12.5 hours per day. They live in a wide variety of hidden places near food sources, and construct nests from various soft materials. Mice are territorial, and one dominant male usually lives together with several females and young. Dominant males respect each other's territories and normally enter another's territory only if it is vacant.

Melatonin may increase sleep length during both daytime and nighttime sleep in people who work night shifts. Zopiclone has also been investigated as a potential treatment, but it is unclear if it is effective in increasing daytime sleep time in shift workers. There are, however, no reports of adverse effects. Modafinil and R-modafinil are useful to improve alertness and reduce sleepiness in shift workers.
|
|
There is an active community that experiments with alternative sleeping schedules to achieve more time awake each day, but the effectiveness of this is disputed. Researchers such as Piotr Woźniak argue that such forms of sleep deprivation are not healthy. Woźniak considers the theory behind severe reduction of total sleep time by way of short naps unsound, arguing that there is no brain control mechanism that would make it possible to adapt to the "multiple naps" system. Woźniak says that the body will always tend to consolidate sleep into at least one solid block, and he expresses concern that the ways in which the polyphasic sleepers' attempt to limit total sleep time, restrict time spent in the various stages of the sleep cycle, and disrupt their circadian rhythms, will eventually cause them to suffer the same negative effects as those with other forms of sleep deprivation and circadian rhythm sleep disorder.

Similar endocrine alterations have been shown to occur even after a single night of sleep restriction. In a balanced order, nine healthy normal-weight men spent three nights in a sleep laboratory separated by at least two weeks: one night with a total sleep time of seven hours, one night with a total sleep time of 4.5 hours, and one night with total sleep deprivation (SD). On a standard symptom-rating scale, subjects rated markedly stronger feelings of hunger after total SD than after seven hours of sleep (3.9 ± 0.7 versus 1.7 ± 0.3; P = 0.020) or 4.5 hours sleep (2.2 ± 0.5; P = 0.041). Plasma ghrelin levels were 22 ± 10% higher after total SD than after seven hours of sleep (0.85 ± 0.06 versus 0.72 ± 0.04 ng mL(−1); P = 0.048) with intermediate levels of the hormone after 4.5 hours sleep (0.77 ± 0.04 ng mL(−1)).

Psychiatric mood disorders, such as major depressive disorder (MDD) and bipolar disorder, are intertwined with sleep disorders. This is evident in the high rate of comorbidity with psychiatric disorders and insomnia and other sleep disorders. Most people with psychiatric diagnoses have significantly reduced sleep efficiency and total sleep time compared to controls. Thus it is not surprising that treating insomnia with CBT-I can help to improve mood disorders.
|
|
Many animals and some people tend to wake, or experience a period of very light sleep, for a short time immediately after a bout of REM. The relative amount of REM sleep varies considerably with age. A newborn baby spends more than 80% of total sleep time in REM. REM sleep typically occupies 20–25% of total sleep in adult humans: about 90–120 minutes of a night's sleep.
|
|
However, the only sure and safe way to combat sleep deprivation is to increase nightly sleep time. The Center for Disease Control suggests the following tips to improve sleeping habits. Firstly, have a consistent sleep schedule, wake up and go to bed at the same time everyday including the weekends. Secondly, removing computers, televisions, and other smart devices from a persons bedroom to avoid the use of electronics before bed.
|
|
There are two theories as to why the pro-inflammatory state is reserved for sleep time. First, inflammation would cause serious cognitive and physical impairments if it were to occur during wake times. Second, inflammation may occur during sleep times due to the presence of melatonin. Inflammation causes a great deal of oxidative stress and the presence of melatonin during sleep times could actively counteract free radical production during this time.

According to the Italian P.I. sheet, etizolam belongs to a new class of diazepines, thienotriazolodiazepines. This new class is easily oxidized, rapidly metabolized, and has a lower risk of accumulation, even after prolonged treatment. Etizolam has an anxiolytic action about 6 times greater than that of diazepam. Etizolam produces, especially at higher dosages, a reduction in time taken to fall asleep, an increase in total sleep time, and a reduction in the number of awakenings.
|
|
At a lower altitude, the link between breathing and sleep has been established. At a higher altitude, disruptions in sleep are often linked to changes in the respiratory (breathing ) rhythm. Changes in altitude cause variations in sleep time (reduced to 0% up to 93%), as shown in a study that examined people at sea level and Pikes Peak (4300 meters). These subjects also experienced more frequent arousals and diminished stage 3 and stage 4 sleep.
|
|
The AMI published findings that "total sleep time was substantially reduced as compared to the usual 7–8 hour monophasic nocturnal sleep" while "maintaining good levels of vigilance as shown by the virtual absence of EEG microsleeps." EEG microsleeps are measurable and usually unnoticeable bursts of sleep in the brain while a subject appears to be awake. Nocturnal sleepers who sleep poorly may be heavily bombarded with microsleeps during waking hours, limiting focus and attention.
|
|
Subjectively, women report an increase in night-time awakening and an increase in Total Sleep Time. Pregnant women’s main physiological complaints during the first trimester which disrupt the quality of sleep are nausea and vomiting, urinary frequency, backaches, and feeling uncomfortable and fatigued; as well as tender breasts, headache, vaginal discharge, flatulence, constipation, shortness of breath, and heartburn. Other contributing factors for sleep quality are age, parity, mood disorders, anxiety and primary sleep disorders.
|
|
There are two three-or- more hour naps with a total average sleep time of fourteen hours. Though sleep is a primarily biological process, it can be treated as a behavior. Thus sleep can be altered and managed through practice and can be learned by the child, similarly how adults can alter and manipulate it. Healthy sleep habits can be established during the first four months to lay a foundation for healthy sleep.
|
|
Low doses of alcohol (one beer) appear to increase total sleep time and reduce awakening during the night. The sleep-promoting benefits of alcohol dissipate at moderate and higher doses of alcohol. Previous experience with alcohol also influences the extent to which alcohol positively or negatively affects sleep. Under free- choice conditions, in which subjects chose between drinking alcohol or water, inexperienced drinkers were sedated while experienced drinkers were stimulated following alcohol consumption.
|
|
Zaleplon is slightly effective in insomnia, primarily characterized by difficulty falling asleep. Zaleplon significantly reduces the time required to fall asleep by improving sleep latency and may therefore facilitate sleep induction rather than sleep maintenance. Due to its ultrashort elimination half-life, zaleplon may not be effective in reducing premature awakenings; however, it may be administered to alleviate middle-of-the-night awakenings. However, zaleplon has not been empirically shown to increase total sleep time.
|
|
Sleep deprivation (skipping a night's sleep) has been found to improve symptoms of depression in 40% - 60% of patients. Partial sleep deprivation in the second half of the night may be as effective as an all night sleep deprivation session. Improvement may last for weeks, though the majority (50%-80%) relapse after recovery sleep. Shifting or reduction of sleep time, light therapy, antidepressant drugs, and lithium have been found to potentially stabilize sleep deprivation treatment effects.

Horses obtain needed sleep by many short periods of rest. This is to be expected of a prey animal, that needs to be ready on a moment's notice to flee from predators. Horses may spend anywhere from four to fifteen hours a day in standing rest, and from a few minutes to several hours lying down. However, not all this time is the horse asleep; total sleep time in a day may range from several minutes to two hours.
|
|
Like alcohol, benzodiazepines, such as alprazolam, clonazepam, lorazepam, and diazepam, are commonly used to treat insomnia in the short-term (both prescribed and self-medicated), but worsen sleep in the long-term. While benzodiazepines can put people to sleep (i.e., inhibit NREM stage 1 and 2 sleep), while asleep, the drugs disrupt sleep architecture: decreasing sleep time, delaying time to REM sleep, and decreasing deep slow-wave sleep (the most restorative part of sleep for both energy and mood).
|
|
Animals studies showed that sleep deprivation prior to a brain injury might have healthy effects. Five days of complete sleep deprivation in rats before the traumatic brain injury, acted as protection against ischemic injury and a habitual deceased in total amount of sleep time before TBI reduced the severity. There are several theories on the protectional effects of sleep disturbances before an injury in rats. Firstly, it may alter the pattern of gene activation and deactivation.

As with alcohol, the effects of benzodiazepine on neurochemistry, such as decreased levels of serotonin and norepinephrine, are believed to be responsible for the increased depression. Additionally, benzodiazepines can indirectly worsen mood by worsening sleep (i.e., benzodiazepine-induced sleep disorder). Like alcohol, benzodiazepines can put people to sleep but, while asleep, they disrupt sleep architecture: decreasing sleep time, delaying time to REM sleep, and decreasing deep sleep (the most restorative part of sleep for both energy and mood).

Elderly human patients with more galanin neurons in their intermediate nucleus (the human equivalent of the VLPO galanin neurons in rodents) have better, more continuous sleep. A reduced number of VLPO neurons is associated with more fragmented sleep (more awakenings throughout the night). Lesions in the VLPO in rats results in 50-60% decrease in NREM sleep time and prolonged insomnia. More recent research suggests that stress-induced insomnia could be due to an imbalance of input to arousal system and VLPO neurons.

A case of spiritualist India, Indian Fables Stories Panchatantra are the most seasoned enduring accounts of humankind, getting by for a considerable length of time, from mouth to mouth, before they were recorded. You will cherish the clear pace of the tales, and they generally make for extraordinary sleep time or narrating meetings. Offer them will all story darlings, and let them appreciate the light, captivating existence of the narratives. The Panchatantra is an antiquated Indian assortment of between related creature tales in Sanskrit section and composition.

Sleeping African dwarf Fischer's chameleon A Komodo dragon sleeping. Reptiles have quiescent periods similar to mammalian sleep, and a decrease in electrical activity in the brain has been registered when the animals have been asleep. However, the EEG pattern in reptilian sleep differs from what is seen in mammals and other animals. In reptiles, sleep time increases following sleep deprivation, and stronger stimuli are needed to awaken the animals when they have been deprived of sleep as compared to when they have slept normally.

It has been shown that activation of NPSR by NPS affects both gastrointestinal motility and mucosal permeability simultaneously. Aberrant signaling and upregulation of NPSR1 could potentially exacerbate dysmotility and hyperpermeability by local mechanisms in gastrointestinal functional and inflammatory reactions. The very rare NPSR mutation Y206H, which makes the receptor more sensitive to NPS, is found in human families that need less sleep time than normal ones. It has similar effects in transgenic mice, making them resistant to memory impairment caused by lack of sleep.

A sleep diary can be used to keep track of the individual's sleep patterns. The diary should include time to bed, total sleep time, time to sleep onset, number of awakenings, use of medications, time of awakening, and subjective feelings in the morning. The sleep diary can be replaced or validated by the use of out-patient actigraphy for a week or more, using a non-invasive device that measures movement. Workers who complain of insomnia should not routinely have polysomnography to screen for sleep disorders.

Firstly, an infant from one to three months of age may sleep sixteen to eighteen hours a day in periods that last from three to four hours. By three months the period of sleep lengthens to about four or five hours, with a decrease in the total sleep time to about fourteen or fifteen hours. At three months, they also start to sleep when it is dark and wake when it is light. They have begun to sync their sleep clocks with the time of day.

Sleep architecture can be adversely affected by benzodiazepine dependence. Possible adverse effects on sleep include induction or worsening of sleep disordered breathing. Like alcohol, benzodiazepines are commonly used to treat insomnia in the short term (both prescribed and self-medicated), but worsen sleep in the long term. Although benzodiazepines can put people to sleep, while asleep, the drugs disrupt sleep architecture, decreasing sleep time, delayed and decreased REM sleep, increased alpha and beta activity, decreased K complexes and delta activity, and decreased deep slow-wave sleep (i.e.

The pattern typically does some kind of task that is not subject of real-time computing. An example would be the task of sending e-mails, where the end-user waiting several minutes is not a problem. The pattern design will typically implement worker thread that accesses a message queue that holds all unprocessed tasks and regularly check and process these tasks. If there are no tasks the worker thread will sleep for an increasingly long time until there are tasks in the queue again; when this occurs the sleep time is reset.

A horse kept alone will not sleep well because its instincts are to keep a constant eye out for danger. Unlike humans, horses do not sleep in a solid, unbroken period of time, but take many short periods of rest. Horses spend four to fifteen hours a day in standing rest, and from a few minutes to several hours lying down. Total sleep time in a 24-hour period may range from several minutes to a couple of hours, mostly in short intervals of about 15 minutes each.

Lendrum discovered that the birds in the calm environment spent substantially more time with their eyes closed than those in the aggressive environment. Lendrum collected data on the doves' opened- and closed-eye sleep; flocking was associated with an increase in a bird's overall eye-closure time and a decrease in its amount of eye-opening. In the presence of a predator, Lendrum found that the doves exhibited higher levels of individual vigilance and increase in open-eye sleep; this reduced the active-sleep component of their total sleep time.

In a study with 3000 patients, it has been found that men and women who sleep less than 5 hours have elevated body mass index (BMI). In another study that followed about 70.000 women for 16 years, there was a significant increase in body weight in those who slept 5 hours or less compared to those who slept 7–8 hours. As sleep time decreased over time from the 1950s to 2000s from about 8.5 hours to 6.5 hours, there has been an increase in the prevalence of obesity from about 10% to about 23%.

Several recent studies have shown that adolescents undergo a change in their circadian cycle which shifts sleep times later into the night. This change seems to occur during puberty, extending well into adulthood. The delay in sleep cycles clashes with the structured early morning schedules of students due to early classes or work; thus, the total amount of sleep time is greatly reduced. There has been a push in many educational systems for a later start time to help increase the available time for sleep in adolescents due to these biological changes.

Inside a Navistar 9000 In the United States, a commercial driver's license is required to drive any type of commercial vehicle weighing or more. The federal government regulates how many hours a driver may be on the clock, how much rest and sleep time is required (e.g., 11 hours driving/14 hours on-duty followed by 10 hours off, with a maximum of 70 hours/8 days or 60 hours/7 days, 34 hours restart ) Violations are often subject to significant penalties. Instruments to track each driver's hours must sometimes be fitted.

Because many of these shows aired on the same day, Mie and Kei had to commute from one network to another, with both of them having an average daily sleep time of 45 minutes. The duo's hectic schedule created the term in Japan's entertainment world. Pink Lady's net worth at the time was estimated to be between 20 billion and 50 billion, but T&C; Music initially paid Mie and Kei 300,000 per month each on their first year; afterwards, their salary was raised to 3 million per month.

Understanding of this mechanism came when reduced thermal regulation was observed in the hyraxes, which are placental mammals. The echidna was originally thought to experience no rapid eye movement sleep. However, a more recent study showed that REM sleep accounted for about 15% of sleep time observed on subjects at an environmental temperature of 25 °C (77 °F). Surveying a range of environmental temperatures, the study observed very little REM at reduced temperatures of 15 °C (59 °F) and 20 °C (68 °F), and also a substantial reduction at the elevated temperature of 28 °C (82 °F).

Mastering urinary control during sleep time is a normal part of childhood development and may be delayed by stress and social pressures. The risk for enuresis increases threefold for children who experience stress, demonstrated by the higher prevalence of enuresis in lower socioeconomic groups. Anxiety experienced by a child between ages 2 to 4 also increases the risk for enuresis because this particular time period is sensitive for the development of nighttime bladder control. Nocturnal enuresis has been found to be more common in those with developmental delay, physical or intellectual disabilities, and psychological or behavioral disorders.

De Moivre continued studying the fields of probability and mathematics until his death in 1754 and several additional papers were published after his death. As he grew older, he became increasingly lethargic and needed longer sleeping hours. A common, though disputable, claim is that he noted he was sleeping an extra 15 minutes each night and correctly calculated the date of his death as the day when the sleep time reached 24 hours, 27 November 1754. On that day he did in fact die, in London and his body was buried at St Martin-in-the-Fields, although his body was later moved.

Individuals with BD benefit from a higher level of stability in their sleep and daily routines than those with no history of affective illness. It is important to identify situations in which routines can be thrown off balance, whether by excessive activity and overstimulation or lack of activity and under-stimulation. Once destabilizing triggers are identified, reasonable goals for change are established. Specific strategies include: # Encouraging proper sleep hygiene to introduce regularity to sleep-wake cycle ## Establish a regular wake and sleep time ## Avoid caffeine or other stimulants ## Use the bed only for sleep and sex, not for watching TV, doing homework, reading etc.

A concept developed further with Aaltonen. Despite many podium finishes on European rallies, a long held ambition to win a Liege in an Austin-Healey 3000 proved elusive until 1964, when he co-drove with Rauno Aaltonen to win the last Spa-Sofia-Liege, an event lasting four days and nights with no scheduled sleep time. Aaltonen later recalled how Ambrose had driven at night in just 52 minutes, reaching speeds of per hour over cobblestone roads whilst Aaltonen slept in the car. The following year they won the 1965 European Rally Championship title, including victory at the RAC Rally in a Mini Cooper 1275S.

The main reason for this development is the fact that, while retaining mobility, actigraphy offers reliable results with an accuracy that is close to those of polysomnography (above 90% for estimating total sleep time but dropping to 55% for a 4 - way sleep stage estimation problem).Girardin, Jean-Louis, von Gizycki, H., Zizi, F., Spielman, A., Hauri, P., & Taub, H. (1997) The actigraph data analysis software: I. A novel approach to scoring and interpreting sleep–wake activity. Perceptual and Motor Skills, 85, 207–216. The technique is increasingly employed in new drug clinical trials where sleep quality is seen as a good indicator of quality of life.

They improve sleep-related problems by shortening the time spent in bed before falling asleep, prolonging the sleep time, and, in general, reducing wakefulness. However, they worsen sleep quality by increasing light sleep and decreasing deep sleep. Other drawbacks of hypnotics, including benzodiazepines, are possible tolerance to their effects, rebound insomnia, and reduced slow-wave sleep and a withdrawal period typified by rebound insomnia and a prolonged period of anxiety and agitation. The list of benzodiazepines approved for the treatment of insomnia is fairly similar among most countries, but which benzodiazepines are officially designated as first-line hypnotics prescribed for the treatment of insomnia varies between countries.

It is also being speculated that homeostatic regulation mechanisms may be altered during adolescence. Apart from this, the effect of changing routines of adolescents on other behavior such as cognition and attention is yet to be studied. Ohayon et al, for example, have stated that the decline in total sleep time from childhood to adolescence seems to be more associated with environmental factors rather than biological feature. In adulthood, the sleep architecture has been showing that the sleep latency and the time spent in NREM stages 1 and 2 may increase with aging, while the time spent in REM and SWS sleep seem to decrease.

Moreover, severe OCD symptoms are consistently associated with greater sleep disturbance. Reduced total sleep time and sleep efficiency have been observed in people with OCD, with delayed sleep onset and offset and an increased prevalence of delayed sleep phase disorder. Behaviorally, there is some research demonstrating a link between drug addiction and the disorder as well. For example, there is a higher risk of drug addiction among those with any anxiety disorder (possibly as a way of coping with the heightened levels of anxiety), but drug addiction among people with OCD may serve as a type of compulsive behavior and not just as a coping mechanism.

Even long-term treatment with trimipramine for up to 2 years has not been found to suppress REM sleep. In addition, trimipramine has been found to decrease nocturnal cortisol levels to normal and to normalize cortisol response in depressed patients; hence, it normalizes the hypothalamic–pituitary–adrenal axis, whereas imipramine and other antidepressants tend to increase nocturnal cortisol secretion. In clinical studies, trimipramine has been found in doses of 50 to 200 mg/day to significantly increase sleep efficiency and total sleep time and to decrease waking time for up to 3 weeks in patients with insomnia. It also improved subjectively perceived sleep quality and well-being during daytime.

Research on the effects of light therapy on seasonal affective disorder suggests that light deprivation is related to decreased activity in the serotonergic system and to abnormalities in the sleep cycle, particularly insomnia. Exposure to light also targets the serotonergic system, providing more support for the important role this system may play in depression. Sleep deprivation and light therapy both target the same brain neurotransmitter system and brain areas as antidepressant drugs, and are now used clinically to treat depression. Light therapy, sleep deprivation and sleep time displacement (sleep phase advance therapy) are being used in combination quickly to interrupt a deep depression in people who are hospitalized for MDD.

National Geographic Magazine has reported that the demands of work, social activities, and the availability of 24-hour home entertainment and Internet access have caused people to sleep less now than in premodern times."U.S. Racking Up Huge "Sleep Debt"" , National Geographic Magazine, 24 February 2005 USA Today reported in 2007 that most adults in the USA get about an hour less than the average sleep time 40 years ago. Other researchers have questioned these claims. A 2004 editorial in the journal Sleep stated that according to the available data, the average number of hours of sleep in a 24-hour period has not changed significantly in recent decades among adults.

Furthermore, the editorial suggests that there is a range of normal sleep time required by healthy adults, and many indicators used to suggest chronic sleepiness among the population as a whole do not stand up to scientific scrutiny. A comparison of data collected from the Bureau of Labor Statistics' American Time Use Survey from 1965–1985 and 1998–2001 has been used to show that the median amount of sleep, napping, and resting done by the average adult American has changed by less than 0.7%, from a median of 482 minutes per day from 1965 through 1985, to 479 minutes per day from 1998 through 2001.

No long-term follow-up was conducted; it is therefore unclear if this intervention has lasting effects on memory. There are a loosely associated group of mnemonic principles and techniques that can be used to vastly improve memory known as the art of memory. The International Longevity Center released in 2001 a report which includes in pages 14–16 recommendations for keeping the mind in good functionality until advanced age. Some of the recommendations are to stay intellectually active through learning, training or reading, to keep physically active so to promote blood circulation to the brain, to socialize, to reduce stress, to keep sleep time regular, to avoid depression or emotional instability and to observe good nutrition.

On his 1973 live album Live in Japan: Spring Tour 1973 and his 1990 live album Rising, Donovan explains the story and sings the previously omitted verse. The last verse of "Hurdy Gurdy Man", written by Harrison, is: "When the truth gets buried deep / Beneath a thousand years of sleep / Time demands a turn around / And once again the truth is found". Donovan's songwriting for The Hurdy Gurdy Man centered on drones on such songs as "Peregrine", "The River Song" and "Tangier" (the latter two being compositions by his friend "Gypsy Dave" (Gyp Mills), and pop music on most of the other tracks. "As I Recall It" continued Donovan's infatuation with jazz.

Individuals may differ in their susceptibility to jet lag and in how quickly they can adjust to new sleep–wake schedules. Short-acting sleep medications can be used to improve sleep quality and timing, and stimulating substances such as caffeine can be used to promote wakefulness, though research results on their success at adapting to jet lag are inconsistent. For time changes of fewer than three hours, jet lag is unlikely to be a concern, and if travel is for short periods (three days or fewer) retaining a "home schedule" may be better for most people. Sleeping on the plane is only advised if it is within the destination's normal sleep time.

Authors concluded that both the Fitbit One and Fitbit Flex devices reliably measured step counts and energy expenditure, with hip-based Fitbit devices being more accurate than wrist- based devices. A 2019 study found that the Fitbit Charge 2 accurately measures the average heart rate of healthy adults during sleep, and that it is most accurate for medium range of heart rate. A 2019 study found that Fitbit Charge 2 relative to EEG, overestimated sleep efficiency by about 4%, but there was no difference in measured total sleep time. A 2019 review found that Fitbit devices, which utilize the sleep-staging feature, show a better performance than non-sleep-staging models, especially in differentiating wake from sleep.

Although SWD affects a majority of shift workers, its manifestation is still unclear within the general shift-working population. A field study investigating the nature of SWD in an experimental (with SWD) and control (non-SWD) group of Finnish shift workers revealed decreased total sleep time (TST) and increased sleep deficit before morning shifts. Furthermore, the SWD group also exhibited decreased objective sleep efficiency, decreased in sleep compensation over the weekends, increased sleep latency, and finally poorer sleep quality was recorded in the SWD group compared to the non-SWD group. Moreover, shift workers with SWD scored significantly higher on the Karolinska Sleepiness Scale (KSS) when assessed at the end of night shifts but at the beginning and the end of morning shifts.

After spinning upright (in the so-called "sleep" position) for an extended period, the angular momentum will gradually lessen (mainly due to friction), leading to ever increasing precession, finally causing the top to topple and roll some distance on its side. In the "sleep" period, and only in it, provided it is ever reached, less friction means longer "sleep" time (whence the common error that less friction implies longer global spinning time). The total spinning time of a top is generally increased by increasing its moment of inertia and lowering its center of gravity.. These variables however are constrained by the need to prevent the body from touching the ground. Asymmetric tops of virtually any shape can also be created and designed to balance.

Slow wave sleep (SWS) has often been associated with successful performance in declarative memory recall tasks. For example, declarative and procedural memory recall tasks applied over early and late nocturnal sleep, as well as wakefulness controlled conditions, have been shown that declarative memory improves more during early sleep (dominated by SWS) while procedural memory during late sleep (dominated by REM sleep). Based on targeted memory reactivation (TMR) that use associated memory cues for triggering memory traces during sleep, recent studies have been reassuring the importance of nocturnal SWS for the formation of persistent memories in neocortical networks, as well as highlighting the possibility of increasing people's memory performance at declarative recalls. Increased slow activity and sleep time spent in SWS have been also related to better performance in implicit learning.

NSF Sleep Duration Recommendations Chart developed based on NSF's research paper In 2015 NSF released the results of a world-class, research study on sleep duration recommendations. The paper titled " National Sleep Foundation’s sleep time duration recommendations: methodology and results summary" was published in the peer-reviewed Sleep Health Journal. NSF convened an expert panel of 18 leading scientists and researchers tasked with updating the official sleep duration recommendations. The panelists included sleep specialists and representatives from leading organizations including the American Academy of Pediatrics, American Association of Anatomy, American College of Chest Physicians, American Congress of Obstetricians and Gynecologists, American Geriatrics Society, American Neurological Association, American Physiological Society, American Psychiatric Association, American Thoracic Society, Gerontological Society of America, Human Anatomy and Physiology Society, and Society for Research in Human Development.

A cross-sectional study investigated the relationship between several sleep assessment criteria and different shift work schedules (3-day, 6-day, 9-day and 21-day shift) and a control group of day shift work in Korean firefighters. The results found that all shift work groups exhibited significant decreased total sleep time (TST) and decreased sleep efficiency in the night shift but efficiency increased in the rest day. Between-group analysis of the different shift work groups revealed that day shift sleep efficiency was significantly higher in the 6-day shift while night shift sleep efficiency was significantly lower in the 21-day shift in comparison to other shift groups (p < 0.05). Overall, night shift sleep quality was worse in shift workers than those who just worked the day shift, whereas 6-day shift provided better sleep quality compared to the 21-day shift.

Ryan Dombal of Pitchfork gave the album a score of 8.5, earning it the Best New Music tag, and called it "outrageous and eclectic", as well as "similar to its predecessor in its boundless sense of style, swerving from Afrobeats to brushed-snare jazz balladry to one track that sounds like a trap remix of a Bon Iver ayahuasca trip", but "more purposeful" than I Like It When You Sleep. Time considered it one of the Best Albums of 2018, placing it at number nine on their list. However, Conrad Duncan writing for the same site gave the album a positive review, calling it "full of genuine heart, intelligence and wit". Popmatters criticized the album as bloated and inconsistent, stating "The band's reach exceeds their grasp here, and vocalist/band leader Matt Healy's indulgences are often more tiresome than charming", while still praising it as "fascinating".
