Sleep paralysis is harmless but can be scary
Sleep paralysis is a temporary condition where an individual is unable to move or speak while falling asleep or waking up. It is often linked to the rapid eye movement (REM) stage of the sleep cycle, where the eyes move quickly, vivid dreaming occurs, and the body's muscles are relaxed to prevent acting out dreams. During sleep paralysis, an individual may be awake and aware of their surroundings but unable to move, which can be a scary experience.
Sleep paralysis is generally harmless and not a cause for concern. It is estimated that around 20% to 30% of people worldwide experience at least one episode in their lifetime, and it can occur at any age, although it tends to first appear during the teenage years. While it usually lasts only a few seconds to a few minutes, some episodes can last up to 20 minutes. It is important to note that being paralysed during sleep is normal, but people are typically unaware of it because they are asleep.
The exact causes of sleep paralysis are not fully understood, but it has been associated with sleep disorders, mental health conditions, and genetics. People with irregular sleep schedules, such as shift workers or frequent travellers, are more prone to sleep paralysis. Sleeping on the back, high levels of stress, anxiety, or trauma, and underlying conditions like insomnia, narcolepsy, PTSD, or other sleep disorders can also increase the likelihood of experiencing sleep paralysis.
Although sleep paralysis itself is harmless, it can cause emotional distress and anxiety, especially if it occurs frequently. It can be a scary experience due to the feeling of helplessness and the inability to move or speak. Some people may also have hallucinations during an episode, such as the presence of an intruder or a dangerous person in the room, or the sensation of suffocation or floating. These hallucinations can contribute to the frightening nature of sleep paralysis.
If you experience sleep paralysis and feel anxious or concerned, it is recommended to speak with a healthcare provider or a doctor. They may suggest improving sleep quality, changing sleeping positions, reducing stress, or addressing any underlying mental health or sleep disorders that could be triggering the episodes. While there is no treatment to stop an episode once it starts, treatments are available to reduce the frequency of occurrences. Understanding sleep paralysis and knowing that it is generally harmless can help take the fear out of this unusual sleep phenomenon.

It can cause hallucinations, like an intruder in the room
Sleep paralysis is a temporary phenomenon that occurs when an individual is unable to move their body or speak before falling asleep or upon waking up. It is often accompanied by hallucinations, which can be frightening and cause emotional distress. One common hallucination is the perception of an intruder or a dangerous presence in the room, sometimes referred to as sleep paralysis demons. This type of hallucination is known as an intruder hallucination and is associated with the feeling of suffocation or someone sitting on one's chest (chest pressure hallucination).
Intruder hallucinations during sleep paralysis are believed to arise from a combination of endogenous and exogenous stimuli. Endogenous stimuli refer to internal sources, such as the individual's brain activity and mental state, while exogenous stimuli refer to external factors in the environment. In the case of sleep paralysis, there is little blocking of exogenous stimuli, making it easier for external factors to influence the individual's experience. This combination of internal and external stimuli can create vivid and terrifying hallucinations, such as the perception of an intruder in the room.
The experience of intruder hallucinations during sleep paralysis may also be influenced by cultural and spiritual beliefs. For example, in Albanian folklore, sleep paralysis is associated with Mokthi, a male spirit who appears to tired or suffering women and renders them immobile. Similarly, in Bengali folklore, sleep paralysis is believed to be caused by a supernatural entity called Boba, which attacks individuals by strangling them in their sleep. These cultural interpretations of sleep paralysis can shape the content and intensity of hallucinations, including the perception of intruders or malevolent entities.
Additionally, there is a genetic component to sleep paralysis, with twin studies indicating that if one identical twin experiences sleep paralysis, the other twin is highly likely to experience it as well. This suggests that there may be a disruption in a specific physiological function, such as the signaling pathway for arousal or the regulation of melatonin and neural populations. However, further studies are needed to fully understand the underlying causes of sleep paralysis and its associated hallucinations.
While sleep paralysis itself is not harmful, the hallucinations and emotional distress it can cause may lead to anxiety and affect an individual's daytime functioning. Treatment options are available to reduce the frequency of episodes, such as improving sleep quality, changing sleeping positions, and addressing underlying mental health conditions. Understanding the causes and symptoms of sleep paralysis can help reduce the fear associated with these experiences and improve overall sleep health.

It may be linked to other health conditions
Sleep paralysis is linked to several other health conditions, including sleep disorders and mental health conditions. People with irregular sleep schedules, such as shift workers, frequent travellers, or those experiencing jet lag, are more prone to episodes of sleep paralysis. Sleep paralysis is also more common in people with chronic insomnia, and it has been linked to other sleep disorders such as narcolepsy, obstructive sleep apnea (OSA), and post-traumatic stress disorder (PTSD).
Genetics may also play a role, as sleep paralysis sometimes runs in families. Research has found a genetic component in sleep paralysis, with twin studies showing that if one twin of a monozygotic pair (identical twins) experiences sleep paralysis, the other twin is very likely to as well. This suggests that there may be some sort of disruption of a function at the physiological level.
In addition to sleep disorders, sleep paralysis has been linked to mental health conditions such as anxiety, depression, and bipolar disorder. Treating these underlying mental health conditions may help resolve sleep paralysis.
If you are experiencing sleep paralysis, it is important to speak with a healthcare provider to determine if there are any underlying health conditions that may be triggering the episodes. A doctor may refer you to a sleep specialist for further diagnosis, testing, and treatment.

It can be managed by improving sleep quality
Sleep paralysis is a terrifying experience where an individual is unable to move their body or speak right before falling asleep or immediately after waking up. It is a temporary condition that lasts from a few seconds to a few minutes. While there is no treatment to stop an episode once it starts, the frequency of episodes can be reduced.
Sleep paralysis is linked to the rapid eye movement (REM) stage of the sleep cycle. During REM sleep, the eyes move quickly, and vivid dreams occur. The muscles of the body are relaxed to prevent movement, and this is controlled by the brain. Sleep paralysis occurs when an individual wakes up suddenly from REM sleep, regaining awareness while the muscles remain relaxed.
Since sleep paralysis is linked to the quality of sleep, it can be managed by improving sleep quality. Here are some ways to improve sleep quality:
- Get adequate sleep: Ensure you are getting enough sleep each night.
- Sleep position: Try new sleeping positions if you sleep on your back. Sleep experts have found a correlation between sleeping on your back and sleep paralysis.
- Stress management: Reduce stress, especially before bedtime.
- Substance use: Avoid alcohol and nicotine. Limit caffeine intake, and do not consume caffeine after 2 pm.
- Rituals: Develop bedtime rituals to signal to your body and mind that it is time for sleep. For example, you could read a book, take a hot bath, practise deep breathing, or listen to calming music.
- Temperature: Keep your bedroom at a comfortable temperature. Around 65°F (18.3°C) is a suitable temperature for most people.
- Meal timings: Eat dinner at least a few hours before bedtime. If you eat late, limit your consumption to a small snack. Avoid high-carb foods at night as they can negatively impact sleep.
- Screen time: Limit screen time before bed. A Norwegian study found that one hour of screen time before bed resulted in a 59% higher risk of insomnia and 24 fewer minutes of sleep.
- Ambience: Ensure your bedroom is quiet, dark, and comfortable.
- Relaxation techniques: Practise relaxation techniques before bed, such as deep breathing or visualization.
- Sunlight exposure: Get daily sunlight exposure or use artificial bright light devices if you cannot get natural sunlight. A 2017 study found that exposure to bright light in the morning improved sleep quality and synchronization of the body's internal clock.

It can be treated by addressing underlying issues
Sleep paralysis is a parasomnia, or abnormal behaviour, that occurs during sleep. It is characterised by the inability to move one's body, right before falling asleep or upon waking up. This temporary paralysis can last from a few seconds to a few minutes, and it is often accompanied by hallucinations, a sense of pressure or choking, and feelings of fear and anxiety.
While there is no treatment to stop a sleep paralysis episode once it has started, addressing underlying issues can help reduce the frequency of episodes. Sleep paralysis has been linked to various factors, including sleep disorders, mental health conditions, and genetic predispositions.
One way to address underlying issues is to improve sleep hygiene, which refers to habits that promote better sleep. This includes maintaining a consistent sleep schedule, avoiding caffeine and alcohol, particularly in the evenings, and reducing screen time before bed. Getting adequate sleep is crucial, as sleep deprivation can trigger sleep paralysis.
For those experiencing stress, anxiety, or other mental health concerns, seeking treatment for these conditions can help alleviate sleep paralysis episodes. Cognitive behavioural therapy (CBT) is one approach that can help individuals manage stress and improve their sleep quality. Additionally, medication may be prescribed to treat underlying mental health disorders, such as antidepressants or low-dose depression medication.
In some cases, sleep paralysis may be a symptom of a more serious sleep disorder, such as narcolepsy or insomnia. If this is suspected, a healthcare provider may recommend further testing, such as an overnight sleep study or a multiple sleep latency test (MSLT), to determine the presence of these disorders. Treating the underlying sleep disorder can help reduce the occurrence of sleep paralysis episodes.
By addressing these underlying issues and following recommended treatments, individuals can effectively manage sleep paralysis and reduce the frequency and impact of episodes.

Frequently asked questions
Sleep paralysis is when you are unable to move or speak for a short time after waking up or while falling asleep. It is a temporary phenomenon and usually lasts a few seconds to a few minutes.
During sleep paralysis, you are awake but unable to move. It can be a scary experience, and people often report feeling anxious or confused. Sleep paralysis is also associated with hallucinations in about 75% of cases. People often sense a dangerous presence, feel like their body is moving, or experience sensations of suffocation and pressure on the chest.
Sleep paralysis occurs during transitions between sleep and wakefulness, typically during the REM stage of sleep when the body is temporarily paralysed to prevent acting out dreams. It is believed that during sleep paralysis, the mind is awake or half-awake, resulting in the awareness of being paralysed. Sleep paralysis can be influenced by various factors, including stress, irregular sleep schedules, and underlying health conditions such as narcolepsy, PTSD, or anxiety disorders.
While sleep paralysis does not typically require treatment, it is important to address any underlying issues that may be contributing to disrupted sleep. Creating a consistent and relaxing bedtime routine can help stabilise your sleep cycle and reduce the likelihood of experiencing sleep paralysis. If you feel anxious about your symptoms or experience daytime sleepiness, it is recommended to consult a healthcare provider for further evaluation and guidance.
