Sleep deprivation has been used as an interrogation technique for centuries. It is considered a form of torture and has been used by the British military, the US military, and the CIA. Despite its prevalence, there is little scientific evidence on how sleep deprivation affects behaviour during interrogation. Sleep deprivation can lead to hallucinations, psychosis, and schizophrenia, as well as a decline in cognitive abilities, making it difficult for individuals to anticipate risks and consequences, inhibit impulses, and resist suggestive influences.

Sleep deprivation is a form of torture
Sleep deprivation has been used as a means of interrogation and as a form of torture for centuries. The practice has been used by various governments and organisations, including the British military, the Central Intelligence Agency (CIA), and the Soviet Union's NKVD.
During World War II, the British operated a POW interrogation facility known as the London Cage, where prisoners were subjected to sleep deprivation, among other forms of torture. More recently, the CIA's use of sleep deprivation following the 9/11 terrorist attacks has been well-documented. In one case, a detainee was shackled to the ceiling and deprived of sleep for up to 180 hours (over seven days).
Sleep deprivation as an interrogation technique is intended to extract information from individuals. However, it often results in disorderly and irrational statements, rather than reliable intelligence. Sleep-deprived individuals experience cognitive impairments, mood disturbances, and an increased risk for chronic health conditions. They may also experience hallucinations, psychosis, and psychotic episodes.
The use of sleep deprivation as an interrogation technique has been the subject of court trials and ethical debates. While some argue that it does not constitute torture, others maintain that it is a form of torture that violates human rights. Research has linked sleep deprivation to false confessions and distorted memories, raising serious concerns about its use in interrogations.
Ultimately, sleep deprivation has been employed as a tool to compel disclosure and extract information, with detrimental effects on the health and well-being of those subjected to it.

Sleep deprivation is used to extract information
Sleep deprivation has been used for centuries as a means of interrogation and to extract information. It is considered one of five illegal interrogation techniques practised by the British military. The CIA has also been known to use sleep deprivation as an "enhanced interrogation technique", keeping detainees awake for up to 180 hours, often in stress positions.
The use of sleep deprivation as a tool to extract information relies on the fact that it impairs cognitive abilities, making it harder for the subject to resist a coercive environment. It can also reduce inhibitory control, leading to riskier decisions and interfering with the subject's ability to anticipate and measure the consequences of their actions. Sleep-deprived people may also be more vulnerable to suggestive influences and are more likely to provide false confessions.
Historically, sleep deprivation has been used to compel confessions from innocent and guilty suspects alike. For example, in 16th-century Scotland, women accused of witchcraft were deprived of sleep for days, and their hallucinations were interpreted as confessions.
Despite its long history as an interrogation technique, there is limited scientific evidence on how sleep deprivation shapes behaviour in interrogation settings. Some studies suggest that sleep-deprived participants provided less information and showed less motivation to recall information. However, the effectiveness of sleep deprivation as a means to extract accurate information is questionable, as it can lead to disorderly and irrational statements, hallucinations, and psychosis.

Sleep deprivation causes hallucinations
Sleep deprivation has been used as an interrogation technique for centuries. It is believed that using sleep deprivation, along with other forms of torture, helps extract information. During Apartheid, Black women in prison were subjected to sleep deprivation, and as hallucinations began, the women had growing fears that men were trying to enter their cells. In 16th-century Scotland, civilians conducted several nationwide witch hunts, and to get a confession, they would keep the accused women awake for days, after which they would begin to hallucinate. The things these women said and did during their hallucinations were interpreted as confessions.
Sleep deprivation can cause a person to hallucinate, and these hallucinations can be in any of the three sensory modalities: visual, somatosensory, and auditory. These hallucinations can happen when an individual gets so overtired that their brain starts to misfire, causing them to see or hear things that aren't really there. For example, they may see flashes of light, shadows, or faces that don't exist or hear voices or strange sounds. Less commonly, they may feel sensations like bugs crawling on their skin.
Hallucinations from sleep deprivation usually occur after 24 hours or more of not sleeping but worsen the longer a person goes without sleep. In some cases, it may feel like one is dreaming while being awake. As the sleep deprivation continues, an individual will experience complex hallucinations and disordered thinking after 48–90 hours, followed by delusions after 72 hours. By the third day without sleep, hallucinations in all three sensory modalities are reported.
While the hallucinations caused by sleep deprivation typically aren't permanent, they do indicate that the body is in distress and desperately needs rest to recover. Sleep deprivation can also trigger or worsen conditions like anxiety, depression, bipolar disorder, and schizophrenia.

Sleep deprivation causes psychotic episodes
Sleep deprivation has been used as an interrogation technique and a form of torture for centuries. For example, during Apartheid, Black women in prison were subjected to sleep deprivation, which caused hallucinations and growing fears that men were attempting to enter their cells. Similarly, in 16th-century Scotland, women accused of witchcraft were deprived of sleep for days, and their actions and words during hallucinations were interpreted as confessions.
Sleep deprivation psychosis is a condition that underscores the intricate relationship between sleep and mental health. It is characterised by severe psychotic symptoms, including intense paranoia, severe disorientation, and an inability to distinguish between reality and hallucinations. Cognitive functions become severely impaired, leading to disorganized thought processes and incoherent communication. Sleep deprivation psychosis can also exacerbate pre-existing mental health conditions.
The treatment for sleep deprivation psychosis depends on various personal factors, including the underlying causes and symptoms experienced. Therapeutic modalities, such as CBT, can help individuals identify and modify negative thought patterns and behaviours associated with sleep deprivation psychosis. Medications, such as antipsychotics or mood stabilizers, may also be prescribed to alleviate acute symptoms.

Sleep deprivation is linked to false confessions
Sleep deprivation has been used as a form of torture and a means of interrogation for centuries. It has been used by various governments and intelligence agencies, including the British military, the Central Intelligence Agency (CIA), and the Soviet Union's NKVD.
Sleep deprivation as an interrogation technique aims to extract information from individuals by keeping them awake for prolonged periods, sometimes using physical restraints and stress positions. This practice is believed to enhance information gathering by causing cognitive impairments and irrational behaviour.
However, there is growing evidence that sleep deprivation is linked to false confessions, raising ethical concerns about its use in interrogations. Research suggests that sleep deprivation impairs complex decision-making abilities, such as anticipating risks and consequences, inhibiting impulses, and resisting suggestive influences. It reduces inhibitory control, leading to riskier decisions and distorted memories of past events.
Studies have found that a majority of known false confessions occurred following interrogations that lasted more than 12 hours, with many lasting longer than 24 consecutive hours. Sleep-deprived individuals may be more susceptible to providing false information or confessing due to their impaired cognitive state.
Additionally, sleep deprivation can have adverse health consequences, including hallucinations, psychosis, mood disturbances, and increased risk for chronic health conditions. As such, its use as an interrogation technique has been controversial, with debates over whether it constitutes torture. While some argue that it does not meet the legal definition of torture, others emphasize the extreme mental and physical distress it causes, which can lead to unreliable and incoherent statements.
