Multiple hypotheses explain the possible connections between sleep and learning in humans. Research indicates that sleep does more than allow the brain to rest; it may also aid the consolidation of long-term memories.
Sleep is a state of reduced mental and physical activity in which consciousness is altered and certain sensory activity is inhibited. During sleep, there is a marked decrease in muscle activity and interactions with the surrounding environment. While sleep differs from wakefulness in terms of the ability to react to stimuli, it still involves active brain patterns, making it more reactive than a coma or disorders of consciousness.
Dick & Dom in da Bungalow is a British children's television series presented by the duo Dick and Dom. The series was broadcast on weekend mornings for five series on the CBBC Channel, BBC One and BBC Two, running between 31 August 2002 and 11 March 2006.
Polyphasic sleep is the practice of sleeping during multiple periods over the course of 24 hours, in contrast to monophasic sleep, which is one period of sleep within 24 hours. Biphasicsleep refers to two periods, while polyphasic usually means more than two. Segmented sleep and divided sleep may refer to polyphasic or biphasic sleep, but may also refer to interrupted sleep, where the sleep has one or several shorter periods of wakefulness, as was the norm for night sleep in pre-industrial societies.
Fear Factor is an American stunt/dare game show that first aired on NBC from 2001 to 2006 and was initially hosted by comedian and UFC commentator Joe Rogan. The show was adapted by Endemol USA from the original Dutch series titled Now or Neverland.
Hypersomnia is a neurological disorder of excessive time spent sleeping or excessive sleepiness. It can have many possible causes and can cause distress and problems with functioning. In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), hypersomnolence, of which there are several subtypes, appears under sleep-wake disorders.
Sleep hygiene is a behavioral and environmental practice developed in the late 1970s as a method to help people with mild to moderate insomnia. Clinicians assess the sleep hygiene of people with insomnia and other conditions, such as depression, and offer recommendations based on the assessment. Sleep hygiene recommendations include: establishing a regular sleep schedule, using naps with care, not exercising physically too close to bedtime, limiting worry, limiting exposure to light in the hours before sleep, getting out of bed if sleep does not come, not using bed for anything but sleep and sex, avoiding alcohol in the hours before bedtime, and having a peaceful, comfortable and dark sleep environment.
BrainTeaser was a British game show based on the original Dutch format of Puzzeltijd. The show was broadcast live, with phone-in viewer puzzles being announced and played during the show in addition to the studio game. During its run from 5 August 2002 to 7 March 2007, it aired on Five Mondays to Fridays, usually for an hour around lunchtime, and was fronted by various presenters rotating with one another. Beginning in August 2005, a version of the show that exclusively focused on viewer participation was broadcast in a four-hour long block on YooPlay TV every day after the Five broadcast, as part of a thirteen-week trial.
The Multiple Sleep Latency Test (MSLT) is a sleep disorder diagnostic tool. It is used to measure the time elapsed from the start of a daytime nap period to the first signs of sleep, called sleep latency. The test is based on the idea that the sleepier people are, the faster they will fall asleep.
Randy Gardner is an American man from San Diego, California, who once held the record for the longest amount of time a human has gone without sleep. In December 1963/January 1964, 17-year-old Gardner stayed awake for 11 days and 24 minutes, breaking the previous record of 260 hours held by Tom Rounds. Gardner’s record was then broken multiple times until 1997, when Guinness World Records ceased accepting new attempts for safety reasons. At that point, the record was held by Robert McDonald at 18 days and 21 hours.
Sleep-deprived driving is the operation of a motor vehicle while being cognitively impaired by a lack of sleep. Sleep deprivation is a major cause of motor vehicle accidents, and it can impair the human brain as much as inebriation can. According to a 1998 survey, 23% of adults have fallen asleep while driving. According to the United States Department of Transportation, twice as many male drivers than female drivers admit to have fallen asleep while driving.
Sleeping while on duty or sleeping on the job – falling asleep while one is not supposed to – is considered gross misconduct and grounds for disciplinary action, including termination of employment, in some occupations. Recently however, there has been a movement in support of sleeping, or napping at work, with scientific studies highlighting health and productivity benefits, and over 6% of employers in some countries providing facilities to do so. In some types of work, such as firefighting or live-in caregiving, sleeping at least part of the shift may be an expected part of paid work time. While some employees who sleep while on duty in violation do so intentionally and hope not to get caught, others intend in good faith to stay awake, and accidentally doze.
In sleep science, sleep onset latency (SOL) is the length of time that it takes to accomplish the transition from full wakefulness to sleep, normally to the lightest of the non-REM sleep stages.
Sleep deprivation, also known as sleep insufficiency or sleeplessness, is the condition of not having adequate duration and/or quality of sleep to support decent alertness, performance, and health. It can be either chronic or acute and may vary widely in severity. All known animals sleep or exhibit some form of sleep behavior, and the importance of sleep is self-evident for humans, as nearly a third of a person's life is spent sleeping. Sleep deprivation is common as it affects about 1/3 of the population.
In 2002, a con was perpetrated by Nik Russian, a British man who, at the time, was working at an entry-level position in a branch of the UK book chain Waterstone's. Russian placed advertisements in major publications that invited people to audition for a year-long reality television programme where they could potentially win a prize of £100,000. After receiving hundreds of responses, he auditioned some of them on Raven's Ait in London, then selected 30 successful auditionees to take part, without informing them that no actual programme had been commissioned. Telling them that the show—to which he had given the working title Project MS-2—would last for an entire year, Russian instructed the participants to leave their homes, quit their jobs and then meet him in London on 10 June, where they would be divided into teams of ten and set their challenge for the next twelve months.
Second wind, a colloquial name for the scientific term wake maintenance zone, is a sleep phenomenon in which a person, after a prolonged period of staying awake, temporarily ceases to feel drowsy, often making it difficult to fall asleep when exhausted. They are the result of circadian rhythms cycling into a phase of wakefulness. For example, many people experience the effects of a second wind in the early morning even after an entire night without sleep because it is the time when they would normally wake up.
The International Civil Aviation Organization (ICAO) defines fatigue as "A physiological state of reduced mental or physical performance capability resulting from sleep loss or extended wakefulness, circadian phase, or workload." The phenomenon places great risk on the crew and passengers of an airplane because it significantly increases the chance of pilot error. Fatigue is particularly prevalent among pilots because of "unpredictable work hours, long duty periods, circadian disruption, and insufficient sleep". These factors can occur together to produce a combination of sleep deprivation, circadian rhythm effects, and 'time-on task' fatigue. Regulators attempt to mitigate fatigue by limiting the number of hours pilots are allowed to fly over varying periods of time.
Naked Attraction is a British television dating game show produced by Studio Lambert and broadcast on Channel 4.

Sleep deprivation – the condition of not having enough sleep – is a common health issue for students in higher education. This issue has several underlying and negative consequences, but there are a few helpful improvements that students can make to reduce its frequency and severity.
