Sleep paralysis is a phenomenon where an individual is conscious but unable to move their body or speak just before falling asleep or upon waking up. Episodes typically last from a few seconds to a few minutes, but longer episodes have been documented. Sleep paralysis is not usually dangerous, but about 10% of people experience recurring episodes, which can be a symptom of a more serious problem. Recurrent isolated sleep paralysis (RISP) involves ongoing instances of sleep paralysis without an association with narcolepsy. RISP is characterised by frequent episodes that cause clinically significant distress or interference.

What You'll Learn
Sleep paralysis is a parasomnia
Sleep paralysis occurs when an individual becomes conscious between sleep phases, stuck between sleep and wakefulness. During the REM stage of sleep, the brain usually paralyses the body's muscles to prevent people from acting out their dreams. However, in sleep paralysis, the mind is awake or half-awake, and the individual becomes aware of their paralysis.
Episodes can be frightening and distressing, sometimes involving hallucinations. These hallucinations can include the perception of a dangerous person or presence in the room, a feeling of suffocation, or the sensation of floating. Sleep paralysis is often associated with narcolepsy, a sleep disorder characterised by sudden episodes of deep sleep. It can also be linked to other serious mental illnesses, such as post-traumatic stress disorder (PTSD), bipolar disorder, and anxiety or panic disorders.
While sleep paralysis is not typically dangerous, recurrent episodes can lead to unhealthy sleep habits and sleep deprivation, resulting in negative health consequences. It is estimated that about 10% of people experience recurrent sleep paralysis, and those affected should seek medical advice if it is causing distress or disrupting their daily lives. Treatment options are available to help reduce the frequency of episodes and manage the condition effectively.
If you are experiencing frequent sleep paralysis or it is causing you distress, it is important to consult a healthcare professional for personalised advice and support. They may refer you to a sleep specialist for further diagnosis, testing, and treatment to help manage your condition.

It is not usually dangerous
Sleep paralysis is a parasomnia, or abnormal behaviour during sleep, that is not usually dangerous. It is a temporary episode that occurs when a person is in both REM and wake states while their body is in a state of REM atonia. During sleep paralysis, a person is conscious of their surroundings but unable to move or speak, which can be a frightening experience. Episodes can last from a few seconds to a few minutes, and may occur once in a person's life or recur over their lifetime.
While sleep paralysis is not dangerous in itself, it can cause emotional distress and anxiety. It can also be linked to other sleep disorders such as narcolepsy and obstructive sleep apnea, which can be serious conditions. Sleep paralysis can also lead to unhealthy sleep habits as people try to avoid experiencing episodes, which can result in sleep deprivation and negative effects on a person's health.
Sleep paralysis is characterised by the inability to move or speak, but the eyes can still move and the person can breathe. It can also be accompanied by hallucinations, which occur in about 75% of episodes. These hallucinations can include the perception of a dangerous person or presence in the room, known as sleep paralysis demons, or feelings of suffocation and chest pressure.
Although sleep paralysis is not typically dangerous, it can be a scary and distressing experience. If a person experiences recurrent episodes or feels anxious about their symptoms, it is recommended that they speak to a doctor. A doctor can help determine if the sleep paralysis is being caused by another condition and prescribe appropriate treatment.
While there are no scientifically proven ways to end a sleep paralysis episode, some strategies may help. These include focusing on small, intentional movements, such as wiggling a finger or toe. It is also important to address the underlying causes of sleep paralysis and practice good sleep hygiene to prevent future episodes.

It can be frightening
Sleep paralysis is a frightening phenomenon in which you are conscious but unable to move. It can cause emotional distress and anxiety. People often experience hallucinations, such as the presence of a dangerous person or a feeling of suffocation. It can be made worse by negative thoughts about sleep, reducing sleep time, and anxiety around bedtime, leading to sleep deprivation and daytime fatigue.
While sleep paralysis is not usually dangerous, about 10% of people experience recurrent episodes, which can be a symptom of a more serious problem. Recurrent sleep paralysis may be a sign of a sleep disorder such as narcolepsy, or a mental illness such as post-traumatic stress disorder (PTSD), bipolar disorder, or anxiety or panic disorders. If you are experiencing frequent episodes of sleep paralysis, it is important to speak with a doctor or healthcare provider.
The exact cause of sleep paralysis is not known, but it is believed to be caused by a disturbed rapid eye movement (REM) cycle. It is often linked to sleep habits such as an irregular sleep schedule or a sleep disorder. Sleep paralysis can affect people of all ages, but it often first appears during teenage years, with episodes becoming more frequent in later years.
There is no treatment to stop a sleep paralysis episode once it is occurring, but treatments are available to reduce the frequency of episodes. Cognitive-behavioural therapy (CBT) is one approach that has been used to treat sleep paralysis, focusing on psycho-education and modifying thoughts about the sleep paralysis attack. Other prevention techniques include sleep hygiene and relaxation techniques such as diaphragmatic breathing, mindfulness, progressive muscle relaxation, and meditation.
If you are experiencing sleep paralysis, it can be helpful to focus on small, intentional movements, such as wiggling a finger or toe, to try to end the episode.

It can be treated with CA-CBT
Sleep paralysis is a frightening phenomenon in which you are conscious but unable to move or speak. It occurs when you're stuck between sleep phases—either just as you're falling asleep or as you're waking up. Episodes can last from a few seconds to a few minutes and may be accompanied by vivid hallucinations. While sleep paralysis is not considered dangerous, it can cause emotional distress and anxiety. Recurrent episodes can lead to unhealthy sleep habits and sleep deprivation, affecting your overall health.
Recurrent isolated sleep paralysis (RISP) is a recognised sleep-wake disorder characterised by ongoing episodes that occur independently of other conditions like narcolepsy. RISP is associated with distressing symptoms such as hallucinations, breathing difficulties, and catastrophic worries about the implications of episodes. The condition can lead to avoidance behaviours, shame, embarrassment, daytime sleepiness, and post-episode distress.
Cognitive-behavioural therapy (CBT) has been proposed as a treatment for recurrent isolated sleep paralysis. CBT encourages patients to attempt small, intentional movements during episodes, such as wiggling a finger or toe, to directly disrupt the paralysis and distract attention from frightening symptoms. Breathing techniques are also utilised as a source of relaxation that can be employed during an attack. CBT has been found to decrease the frequency of sleep paralysis episodes, minimise anxiety and rumination about sleep, improve cognitive functioning, and enhance mood during the day.
CA-CBT, or culturally adapted cognitive-behavioural therapy, is a form of CBT that integrates cultural factors into the treatment. It is a flexible approach that considers the cultural context and beliefs of the patient to improve the effectiveness and acceptability of the therapy. CA-CBT has been used to address a range of mental health concerns, including sleep paralysis, in diverse cultural settings. By incorporating cultural elements and tailoring the treatment to the patient's background, CA-CBT can enhance engagement and outcomes.

It can be linked to other disorders
Sleep paralysis is a parasomnia, or an abnormal behaviour that occurs during sleep. It is linked to the rapid eye movement (REM) stage of the sleep cycle. Sleep paralysis is considered harmless and is not a serious medical risk on its own. However, it can cause emotional distress and anxiety about going to sleep, which can lead to unhealthy sleep habits and sleep deprivation. This can have negative effects on a person's overall health.
Sleep paralysis can be linked to other sleep disorders, such as narcolepsy, a neurological disorder that causes sudden episodes of deep sleep due to a problem with the brain's ability to regulate sleep. Other sleep disorders that have been linked to sleep paralysis include:
- Obstructive sleep apnea, which is marked by repeated lapses in breathing
- Insomnia
- Circadian rhythm dysregulation
- Nighttime leg cramps
Sleep paralysis has also been linked to certain mental health conditions, including:
- Bipolar disorder
- Post-traumatic stress disorder (PTSD)
- Panic disorder
- Anxiety disorders
Additionally, certain medications, substance use, and sleep habits such as an irregular sleep schedule or sleep deprivation can also be factors contributing to sleep paralysis.

Frequently asked questions
Sleep paralysis is a phenomenon where one feels conscious but is unable to move their body or speak, right before falling asleep or upon waking up. It is usually not dangerous and lasts for a few seconds to a few minutes.
Apart from the defining symptom of atonia or paralysis, people often experience hallucinations, which can be hypnagogic (when falling asleep) or hypnopompic (when waking up). These hallucinations can include the perception of a dangerous person or presence in the room, sensations of pressure on the chest, or the feeling of floating.
The exact cause of sleep paralysis is not known, but it is believed to be linked to a disturbed rapid eye movement (REM) cycle of sleep. Sleep paralysis is also thought to have a genetic component, and can be caused by stress, irregular sleep schedules, and underlying mental health conditions.
While there is no treatment to stop a sleep paralysis episode, there are ways to reduce its frequency. These include identifying the underlying causes and addressing them, practising relaxation techniques, and seeking medical help if it is severely affecting your sleep or mental health.
