Sleep Paralysis: Daytime Risk And Nighttime Terror

Sleep paralysis is a condition in which a person is unable to move or speak as they are falling asleep or waking up. It happens when the body is between stages of sleep and wakefulness. While it can be a scary experience, it is generally harmless and not dangerous. Sleep paralysis usually lasts for a few seconds to a few minutes, and can be accompanied by hallucinations. It is often linked to sleep disorders, mental health conditions, and disrupted sleeping patterns. While the exact cause of sleep paralysis is not fully understood, it typically occurs during the REM stage of sleep when there is a mixed state of consciousness and wakefulness.

Sleep paralysis is a parasomnia

Episodes of sleep paralysis usually last from a few seconds to a couple of minutes, with an average length of around six minutes. In some cases, they can last up to 20 minutes. These episodes end on their own or when the person experiencing them is touched or moved. Sleep paralysis can occur in otherwise healthy individuals and is surprisingly common. It is estimated that about 20% of people will experience sleep paralysis at some point in their lives, with 30% experiencing at least one episode.

The exact cause of sleep paralysis is unknown, but it is often linked to sleep disorders and certain mental health conditions. Sleep paralysis has been associated with:

• Sleep deprivation
• Irregular sleep schedules, such as shift work or jet lag
• Obstructive sleep apnea
• Mental health conditions like anxiety, bipolar disorder, post-traumatic stress disorder (PTSD), and panic disorder
• Substance use disorders
• Certain medications, such as those used to treat ADHD

There is no specific treatment for sleep paralysis, but improving sleep hygiene and addressing underlying problems can help reduce the frequency and severity of episodes. This includes establishing a consistent sleep schedule, optimising the sleep environment, curbing substance use, and removing electronic distractions before bed. In some cases, medications that prevent REM sleep or treat underlying mental health conditions may be prescribed.

It occurs during the REM sleep stage

Sleep paralysis occurs when a person is unable to move or speak as they are falling asleep or waking up. During an episode, the person is fully conscious and aware of their surroundings. Sleep paralysis happens when the sleep cycle is shifting between stages, specifically when the person wakes up suddenly from REM sleep. When this happens, the brain is awake, but the body remains in REM mode and cannot move, resulting in a feeling of paralysis.

REM sleep, or rapid eye movement sleep, is a stage of sleep characterised by rapid eye movements and vivid dreaming. It is also known as dream sleep, as this is the stage when most dreams occur. During REM sleep, the body is typically paralysed, which prevents us from acting out our dreams and causing potential injury. However, in the case of sleep paralysis, the mind remains awake or partially awake, resulting in the awareness of being unable to move.

Sleep paralysis episodes can last from a few seconds to up to 20 minutes, with the average length being around six minutes. These episodes usually end on their own or when the person is touched or moved. While sleep paralysis itself is not dangerous, it can be a frightening experience for those who undergo it. It is often accompanied by hallucinations or a feeling of suffocation, further adding to the distress of the individual.

Although the exact cause of sleep paralysis is not fully understood, it has been linked to various factors. One common factor is sleep deprivation, or not getting enough sleep. Additionally, irregular sleep schedules, such as those experienced by shift workers, can contribute to sleep paralysis. Sleeping on your back has also been identified as a potential risk factor.

Certain medical conditions are associated with sleep paralysis, including sleep disorders such as narcolepsy and mental health disorders like bipolar disorder, post-traumatic stress disorder (PTSD), anxiety disorders, and panic disorder. The use of certain medications, such as those for attention deficit hyperactivity disorder (ADHD), has also been implicated in sleep paralysis episodes.

It can be accompanied by hallucinations

Sleep paralysis is a temporary inability to move or speak that occurs directly after falling asleep or upon waking up. It is a parasomnia, or an abnormal behaviour during sleep, and is linked to the REM stage of the sleep cycle. During an episode, individuals maintain consciousness and often experience hallucinations and a sensation of suffocation.

Hallucinations during sleep paralysis fall into three categories:

Intruder Hallucinations

These hallucinations involve the perception of a dangerous person or presence in the room. They are often accompanied by chest pressure hallucinations.

Chest Pressure Hallucinations

Also called incubus hallucinations, these episodes may incite feelings of suffocation or the sensation that someone is sitting on your chest.

Vestibular-Motor (V-M) Hallucinations

V-M hallucinations can include feelings of movement, such as flying, or out-of-body sensations.

These hallucinations can be frightening or cause anxiety. They are distinct from typical dreams, and it is common to feel excessively sleepy or fatigued the day after experiencing sleep paralysis.

It can be caused by disrupted sleep patterns

Sleep paralysis is a temporary condition that occurs when you're stuck between sleep phases. It can be caused by disrupted sleep patterns, such as those caused by shift work or jet lag.

Sleep paralysis is the feeling of being conscious but unable to move. It happens when you pass between stages of wakefulness and sleep. During these transitions, you may be unable to move or speak for a few seconds up to a few minutes. It can be quite frightening, but it's not dangerous.

Disrupted sleep patterns can increase the likelihood of sleep paralysis. This includes shift work, which can result in irregular sleep schedules, and jet lag, which can cause sleep deprivation and disrupt the body's natural sleep-wake cycle. Sleeping on your back has also been linked to sleep paralysis.

Additionally, certain medications, such as those used to treat ADHD, have been associated with sleep paralysis. Sleep paralysis can also be a symptom of underlying sleep disorders, such as narcolepsy, or mental health conditions, including bipolar disorder, post-traumatic stress disorder (PTSD), and anxiety or panic disorders.

To prevent sleep paralysis, it is recommended to maintain a consistent sleep schedule, create a comfortable sleep environment, limit substance use, and avoid electronic devices before bedtime.

It can be treated with medication or therapy

Sleep paralysis is a frightening but harmless condition that occurs when a person is conscious but unable to move or speak while falling asleep or waking up. While there is no treatment to stop an episode of sleep paralysis once it starts, medication and therapy can help reduce the frequency of episodes.

Medication

Doctors may prescribe medication to prevent patients from reaching the REM stage of sleep, during which sleep paralysis occurs. Antidepressants such as tricyclic antidepressants (e.g. imipramine, clomipramine, and amitriptyline) and selective serotonin reuptake inhibitors (SSRIs) like fluoxetine can be used to treat sleep paralysis. However, it is unusual for sleep paralysis to be severe enough to require medication.

Therapy

Therapy can be an effective way to treat sleep paralysis. Cognitive behavioural therapy (CBT) can help patients manage stress, anxiety, and depression, which are all factors that can trigger sleep paralysis. Improving sleep hygiene is another way to prevent sleep paralysis episodes. This includes following a regular sleep schedule, avoiding caffeine and alcohol in the evening, and refraining from using screens at least an hour before bed. Getting 7 to 9 hours of sleep per night is also important, as sleep deprivation can trigger sleep paralysis.

In addition, meditation-relaxation (MR) therapy has been found to reduce the frequency and intensity of sleep paralysis episodes. During an episode, patients can try reappraising the meaning of the attack, distancing themselves emotionally and psychologically, trying inward-focused-attention meditation, and relaxing their muscles.
