To date, most sleep deprivation studies have focused on acute sleep deprivation, suggesting that acute sleep deprivation can cause significant damage to cognitive, emotional, and physical functions and brain mechanisms. [11] Few studies have compared the effects of acute total sleep deprivation and chronic partial sleep restriction. [8]
Sleep deprivation is also implicated in impaired ability to retrieve stored long-term memories. When an aversive stimulus was included in a trial (i.e., a blowdryer blasting hot air and noise at a mouse), mice that were sleep deprived were less anxious on subsequent trials.
In individuals deprived of sleep, somnolence may spontaneously dissipate for short periods of time; this phenomenon is the second wind, and results from the normal cycling of the circadian rhythm interfering with the processes the body carries out to prepare itself to rest. The word "somnolence" is derived from the Latin "somnus" meaning "sleep".
The most common sleep-related symptom of bipolar disorder is insomnia, in addition to hypersomnia, nightmares, poor sleep quality, OSA, extreme daytime sleepiness, etc. [27] Moreover, animal models have shown that sleep debt can induce episodes of bipolar mania in laboratory mice, but these models are still limited in their potential to explain ...
Sleep debt or sleep deficit is the cumulative effect of not getting enough sleep. A large sleep debt may lead to mental or physical fatigue, and can adversely affect one's mood, energy, and ability to think clearly. There are two kinds of sleep debt: the result of partial sleep deprivation, and of total sleep deprivation
Sleep paralysis is associated with sleep-related hallucinations. [22] Predisposing factors for the development of recurrent isolated sleep paralysis are sleep deprivation, an irregular sleep-wake cycle, e.g. caused by shift work, or stress. [22] A possible cause could be the prolongation of REM sleep muscle atonia upon awakening. [34]
The information includes sleep onset time, sleep latency, number of awakenings in a night, time in bed, daytime napping, sleep quality assessment, use of hypnotic agents, use of alcohol and cigarettes, and unusual events which may influence a person's sleep. Such a log is usually made for one or two weeks before visiting a somnologist.
Hospital noise, at any volume level, is credited with being the primary cause of sleep deprivation, a contributing factor in delirium, and a risk factor for errors. [7] The current pressure to reduce noise at night has been mistakenly understood to mean undue quiet at night when patients most need cues that people are around them and available ...
