Sleep Deprivation Psychosis 

Sleep deprivation psychosis is a mental health condition caused by extreme lack of sleep, leading to symptoms like hallucinations, delusions, and disordered speech, similar to those in psychosis, which often involves paranoia and emotional instability. 

With 10–30% of the population experiencing chronic sleep difficulties, it’s essential to distinguish sleep deprivation from related issues like sleep insufficiency and insomnia [3]. Understanding these differences and the role of sleep education highlights how lifestyle factors, health conditions, and poor sleep hygiene contribute to the onset and severity of sleep deprivation psychosis.

What is Sleep Deprivation Psychosis?

To understand sleep deprivation psychosis, we need to understand psychosis. Psychosis is a serious mental health condition in which the individual’s perceptions and thoughts are drastically disconnected from reality. A person with this condition experiences hallucinations and confused speech and is often paranoid or emotional, with limited ability to think rationally. 

Sleep deprivation psychosis is a mental health condition that arises from a significant lack of sleep, leading the person to display symptoms similar to psychosis. Their irrational thought patterns may be displayed in disordered speech, strong feelings, seeing things that aren’t there, and unusual or intense ideas that are not aligned with reality. 

 Is it Sleep Deficiency or Insufficiency? 

The terms sleep deficiency and sleep insufficiency are regularly used interchangeably. However, sleep deficiencies are the overarching category under which sleep insufficiency and sleep deprivation fall. 

Sleep deprivation typically refers to a short period of acute sleeplessness, while sleep insufficiency describes a chronic pattern of consistently getting less sleep than needed or having poor-quality sleep. 

One can experience sleep deprivation without psychosis symptoms. Sleep deprivation symptoms may include:

  • Extreme fatigued
  • Drowsy
  • Moody
  • Nauseous
  • Difficulty concentrating
  • Feeling more emotional

Is Sleep Deprivation Different From Insomnia? 

Insomnia is a condition that makes it very challenging for someone to fall asleep or stay asleep. Sleep deprivation is a common side effect of insomnia, but not everyone who suffers from sleep deprivation has insomnia

Sleep deprivation is usually caused by lifestyle factors or obligations such as work, caring for a new baby, or other responsibilities that make it difficult to schedule enough time for rest. Unlike insomnia, sleep deprivation is generally not due to an inability to fall asleep but rather a lack of opportunity to do so [8].

Sleep disturbances, including insomnia, are increasingly recognized as factors that contribute to psychiatric issues like psychosis. The relationship between sleep problems and psychosis is bi-directionally related [4]. 

Insomnia is also linked to higher risks of paranoia. National surveys in the UK, showed that insomnia was associated with approximately 2–3 times higher odds for paranoia – a symptom of psychosis [4]

Is Sleep Deprivation Psychosis a Mental Illness?

Sleep deprivation psychosis is not a recognized mental illness or mental health condition in the DSM5. However, symptoms of sleep deprivation psychosis exhibit significant overlap with various psychiatric conditions. 

Dr. Matthew Walker, Ph.D., a professor of neuroscience and psychology at UC Berkeley, highlights sleep’s crucial role in mental health, noting, “In 20 years of research, we have not been able to discover a single psychiatric condition in which sleep is normal”[hub]. Sleep deprivation can worsen symptoms of anxiety, depression, and other disorders, underscoring the profound link between sleep and mental well-being. Managing psychiatric symptoms and preventing psychotic episodes is not possible without addressing sleep deprivation and insufficiency. 

Types of Sleep Deprivation Psychosis

Two of the most common types of sleep deprivation include:

Acute sleep deprivation psychosis: This is a severe, short-term form of sleep deprivation, occurring over 1-3 days with minimal to no sleep, often triggering psychosis and other psychiatric issues.

Chronic sleep deprivation psychosis: This type is less intense but more prolonged, resulting from consistently inadequate sleep over an extended period. Psychosis symptoms emerge gradually with habitually undersleeping. 

What Causes Sleep Deprivation Psychosis?

Work Obligations

Many individuals have jobs that require disordered sleep schedules. Nurses, firefighters, and nightshift workers often find themselves awake for longer periods and have to fight against their bodies’ natural circadian rhythms to meet the demands of their careers. Habitual sleep irregularities can disrupt one’s sleep health. 

Sleep Disorders

Often, those who suffer from sleep deprivation also struggle with other sleeping disorders, including insomnia, sleep apnea, restless legs syndrome (RLS), circadian rhythm disorders, and parasomnias. The symptoms of disordered sleep patterns contribute to sleeplessness and deprivation, increasing the likelihood of the onset of psychosis. 

Other Medical Conditions

Chronic pain is one of the leading medical conditions connected to sleep deprivation. An estimated 50–80% of the patients with chronic pain experience sleep disturbances. Prolonged pain and sleeplessness had a profound effect on the individual’s physical, emotional, and mental well-being [6]. 

Lifestyle choices

Some people identify as “night owls” and feel most alert, motivated, and creative at night. While this can be fine in moderation, our bodies are naturally attuned to the cycles of sunlight and darkness. Disrupting these signals may lead to habitual sleep patterns that interfere with rest when we finally try to sleep.

Poor Sleep Hygiene

Poor sleep hygiene may contribute to sleep deprivation, including factors like screen time before bed, late-day caffeine, evening alcohol, late-night meals, and limited daytime activity.

Are There Any Symptoms of Sleep Deprivation?

An extensive study on sleep deprivation in 2018 uncovered a range of symptoms. Under a significant lack of sleep, the following symptoms were recorded and divided into specific categories: Visual symptoms, Sensory symptoms, Auditory symptoms, and “other” symptoms [1].

  1. Visual symptoms 
  • Distortions: The objects appear to change in size, seem to move, or shift in shape and color
  • Illusions: Regular objects transforming into faces, animals, or people 
  • Hallucinations: Seeing things that are not happening, such as the floor flooding with liquid or seeing simple geometric shapes change shape or split in two. Most recorded hallucinations were basic in nature, but a few reported seeing animals or people 
  1. Sensory symptoms 
  • Bodily distortions: The person may feel their body has changed in size. They may feel tingles, discomfort, and sudden hot and cold sensations. 
  1. Auditory symptoms 
  • Distortions: Sounds were reportedly too loud or quiet or had an echo. 
  • Hallucinations: Hearing voices or noises that are not real.
  1. Other Symptoms of Sleep Deprivation include:
  • Mood changes: A reported 76% of participants experience one or several mood changes like aggression, anger, apathy, anxiety, and depression [1].
  • Disordered thoughts and behavior:  Over two-thirds of the participants displayed confusion, fragmented thinking, trouble speaking, memory loss, and coordination issues.
  • Dissociation and depersonalization: 50% experienced feelings of separation and body detachment.
  • Delusions: The participants experienced delusions with themes of control, paranoia, and jealousy.
  • Temporal distortions: A limited number (20%) reported feeling time passing slowly and incorrectly judged the passing of time. 

What Are the Results of Sleep Deprivation?

Sleep deprivation has a wide range of consequences that impact physical and mental health and may contribute to the onset of psychosis. Its effects can lead to exhaustion-induced accidents, cardiovascular disease, diabetes, obesity, and immunity issues. Sleep disorders are also largely connected to mental health conditions such as depression, anxiety, bipolar and schizophrenia.

Unintentional Errors and Accidents

Sleep deprivation affects balance and motor coordination, which can cause falls or, in more severe cases, serious injury, especially when operating vehicles and heavy machinery. 

Risks For Physical and Mental Health

While lack of sleep may seem like a common problem, its normality does not diminish its significant impact on physical well-being and mental stability. Lack of sleep can contribute to cardiovascular disease and diabetes. Sleeplessness also exacerbates the presence of mental health disorders like depression and anxiety. 

Cardiovascular Disease

Sleep deprivation can lead to increased inflammation in the body, raising the risk of cardiovascular problems [7]. Quality sleep plays a vital role in regulating body weight, blood pressure, and cholesterol. Poor sleep can disrupt these key health markers, contributing to heart conditions. 

Diabetes

Sleep disorders like sleep apnea, which have a bi-directional relationship with sleep deprivation, are also linked to insulin resistance [9]. This suggests a two-way connection between type 2 diabetes and sleep deprivation, with each condition worsening the other and increasing the prevalence of both harmful health conditions. 

Obesity

Similar to cardiovascular health and type 2 diabetes, obesity and poor sleep are closely linked. Quality sleep is essential for maintaining a healthy weight, as it regulates hormones associated with appetite and metabolism. Sleep deprivation can cause hormonal imbalances, which increase hunger and slow down metabolism, leading to weight gain and obesity.

Immunodeficiency

Sleep deprivation can negatively impact Immunodeficiency (immune system issues). During sleep, the body releases proteins called cytokines. These proteins fight viruses and infections. When sleep is reduced or disrupted, cytokine production drops, weakening the immune response and making people more susceptible to illnesses. 

Hormonal Abnormalities

Cortisol, estrogen, testosterone, and melatonin are all hormones that influence sleep and are, in turn, affected by poor sleep [10]. Disruptions in healthy sleep patterns can lead to imbalances in these hormones, potentially resulting in further health complications.

Pain

Chronic pain can severely disrupt a person’s ability to sleep through the night and achieve restorative REM cycles. Since sleep and pain share similar neurotransmitters, a lack of sleep can limit the body’s ability to cope with pain. Sleep is also the body’s time to reset and heal; when pain interrupts this process, it can hinder recovery and potentially prolong chronic pain issues.

Mental Health Disorders

As mentioned before, after 20 years of research, Dr. Matthew Walker, Ph.D., a professor of neuroscience and psychology at UC Berkeley, states that he and his team were not able to discover a single psychiatric condition in which sleep was normal [hub]. This means sleep disorders and mental health disorders go hand in hand. Similar to our other results of sleep deprivation, these two conditions negatively aggravate the other and worsen symptoms of anxiety, depression, and other mental illnesses. 

Depression

Studies indicate that 75% of individuals with depression experience difficulty falling or staying asleep [11]. Sleep disturbances, often leading to sleep deprivation, are highly prevalent and resistant to treatment in those with depression. Evidence suggests that depression-related changes in brain neurotransmitter function can further reduce one’s quality of sleep [12].

Anxiety

It’s no surprise that anxiety and sleep do not mix well. Anxiety raises cortisol levels, which affects sleep by heightening alertness and signaling to the brain that it’s not time to rest. Conversely, insufficient sleep can also elevate cortisol, creating a cycle where anxiety and sleep issues reinforce each other and impact one’s health.

Sleep disturbances are common prerequisites to the diagnosis of generalized anxiety disorder and PTSD. Research suggests that our stress-related systems, within our nervous system and hormones, contribute to heightened arousal and anxiety, leading to insomnia and other sleep disorders [13].

Bipolar Disorder 

Individuals with bipolar disorder often experience sleep disturbances, which can trigger troublesome psychiatric episodes. Poor sleep can disrupt neurotransmitters, affecting balance and mood stability, and potentially leading to episodes of mania or depression. Adequate sleep is crucial for mood regulation and overall mental stability for all people but may be particularly vital for those balancing their mental health. 

ADHD (Attention Deficit Hyperactivity Disorder)

ADHD often disrupts sleep due to its effect on alertness and hyperactivity, which can interfere with the ability to fall asleep. Since sleep plays a key role in cognitive functioning and impulse control, sleep deprivation can worsen ADHD symptoms. Quality sleep is vital for focus and behavior regulation, so interruptions can intensify the challenges associated with ADHD.

Schizophrenia

Schizophrenia is a severe psychiatric disorder with common symptoms, including delusions, hallucinations, and social isolation. 80% of individuals with Schizophrenia also have sleep disturbances, with insomnia being the most common condition. Sleep disruptions often precede a diagnosis of schizophrenia and may be a key indicator of worsening psychosis. Since sleep and mental health are deeply intertwined, a lack of restful sleep can exacerbate symptoms like delusions, emotional stability, and disorganized thinking. Many studies conclude the treatment of schizophrenia can not be addressed without proper sleep management techniques. 

 Things You Can Do to Improve Sleep

While sleep deprivation and sleep insufficiency may result from uncontrollable circumstances, there are ways to improve sleep habits and establish better rest routines. 

  1. Lifestyle Changes

Lifestyle choices around what we eat, when we sleep, and how we unwind for the night can deeply affect our nightly rest. Avoiding caffeine later in the day is generally recommended, as this stimulant can interfere with circadian rhythms and make it harder to wind down. Additionally, eating large meals before bed is not advised; digestion requires energy, which can keep the body active rather than restful. Establishing a calming pre-sleep routine can cue the body that it’s time for rest—this might include turning off screens an hour before bedtime, enjoying a cup of tea, dimming the lights, or reading a book. Try to avoid activities that may induce stress, like checking emails or social media, as these can disrupt relaxation and spike cortisol levels. 

  1. Physical Activity

Many individuals have mentally demanding jobs but lead relatively sedentary lifestyles due to long hours in the office. Regular physical exercise can significantly enhance sleep quality by burning off pent-up energy, reducing stress, balancing hormones, and promoting deeper, more restorative sleep cycles.

Sleep Hygiene

Sleep hygiene may look different from person to person. But here are a few universally beneficial tips

  • Reserve your bedroom solely for sleep. Doing your homework or watching TV in your bed may subliminally signal to your brain that your bed is a place for wakefulness rather than sleep, which can disrupt healthy sleep patterns. 
  • Make sure your environment is dark, cool, and relatively quiet. Blackout curtains and sound machines can help create an ideal sleep oasis.
  • Find your ideal sleeping position with proper head and neck support from the right pillow.

Relaxation Techniques

Incorporating relaxation techniques like meditation, deep breathing, and mindfulness before bed can significantly improve sleep quality. Many online resources offer quick 5-10 minute sleep meditations that can help establish a restful sleep routine. These guides can help lower the body’s state of alertness and racing thoughts, preparing you for an easier transition into sleep. 

Treatment Options for Sleep Deprivation Psychosis

Sleep deprivation psychosis is a life-altering condition that needs consistent treatment. These treatments may differ between individuals. However, non-pharmacological approaches and medication have proven useful for sleep deprivation and similar sleep disorders. 

Cognitive Behavioral Therapy (CBT)

CBT is a non-pharmacological method (as this therapy is not reliant on medication). Cognitive Behavioral Therapy for insomnia (CBT-I) involves several sessions of therapy meant to refrain unhealthy thought patterns, particularly as they relate to sleep and trauma. This therapy can help you create positive sleep routines and mindful methods of relaxation that rewire the brain and combat sleep disorders like insomnia. 

Other non-pharmacological methods may include

  • Bright light therapy 
  • Sleep restriction therapy
  • Education on Sleep hygiene 
  • The use of sleep trackers

Medications

When nonpharmacological methods prove to be insufficient, the use of medication with these techniques may be necessary. Examples of sleep aid medication include:

  • Melatonin 
  • Antidepressants with sedating effects
  • Sedatives (z-drugs) 

While medication may be necessary for a time to assist in lessening the effects of sleep deprivation psychosis and helping an individual get sufficient sleep, they are not generally long-term solutions. Many sleep medications are addictive and have adverse side effects. Talk to your doctor about long-term goals and seek ways to create sleep solutions outside medical assistance. 

Sleep Deprivation Psychosis FAQ

Is lack of sleep a symptom of psychosis?

Yes, sleep disturbances—such as difficulty falling asleep, lack of sleep, and insomnia—are common in psychosis and can also trigger it. Psychosis and sleep disorders often influence and intensify each other.

What mental illness can you get from sleep deprivation?

Sleep deprivation, combined with other factors, can create the perfect conditions for mental illness to develop. Some mental illnesses associated with sleep deprivation include depression, generalized anxiety disorder, bipolar disorder, and schizophrenia. Quality sleep allows the brain to rest and function properly —without it, individuals may experience mood swings, agitation, sadness, and lack of motivation.

How many days of sleep deprivation does it take to hallucinate?

This may vary from person to person, but studies found that symptoms of perceptual distortions, anxiety, irritability, and depersonalization started within 24–48 hours of sleep loss, with hallucinations and disordered thinking appearing after 48–90 hours [1].

What are the symptoms of extreme sleep deprivation?

Sleep deprivation can cause a range of symptoms that worsen with prolonged sleeplessness. These symptoms include extreme fatigue and drowsiness, mood swings, emotional sensitivity, nausea, impaired cognitive abilities, and memory loss. In more severe cases, individuals may experience hallucinations, as well as visual, auditory, and sensory distortions, along with delusions.

How many hours is severe sleep deprivation?

Sleep deprivation is considered severe after about 48 hours without sleep. This two-day mark often signals the onset of more serious side effects affecting both physical and mental health.

What happens if you are sleep-deprived for too long?

Chronic sleep deprivation can cause long-term health consequences, including a heightened risk of hypertension, diabetes, obesity, depression, heart attack, and stroke [14]. Extended sleep deprivation can also impair cognitive abilities and impact the immune system, making the body more susceptible to illnesses. 

Can your brain recover from sleep deprivation?

Generally, yes. Studies observing individuals undergoing sleep deprivation have shown that a period of normal sleep resolves psychotic symptoms in most cases. Adequate sleep (including a few REM cycles) helps restore cognitive function boosts mood and overall brain health, though this may require several consecutive nights of restful sleep.
