What are the causes of Sleep Paralysis?

Sleep paralysis is fairly common. Many people have at least one episode during their lifetimes.

The exact cause of sleep paralysis is not fully known. Research shows the following are linked to sleep paralysis:

  • Not getting enough sleep
  • Having an irregular sleep schedule, such as with shift workers
  • Mental stress
  • Sleeping on your back

Certain medical problems can be associated with sleep paralysis:

  • Sleep disorders, such as narcolepsy
  • Some mental conditions, such as bipolar disorder, PTSD, panic disorder
  • Use of certain medicines, such as for ADHD
  • Substance use

Sleep paralysis that is not related to a medical problem is known as isolated sleep paralysis.

What are the symptoms of Sleep Paralysis?

The normal sleep cycle has stages, from light drowsiness to deep sleep. During the stage called rapid eye movement (REM) sleep, the eyes move quickly and vivid dreaming is most common. Each night, people go through several cycles of non-REM and REM sleep. During REM sleep, your body is relaxed and your muscles don't move. Sleep paralysis occurs when the sleep cycle is shifting between stages. When you wake up suddenly from REM, your brain is awake, but your body is still in REM mode and can't move, causing you to feel like you're paralyzed.

Episodes of sleep paralysis last from a few seconds to 1 or 2 minutes. These spells end on their own or when you are touched or moved. In rare cases, you can have dream-like sensations or hallucinations, which may be scary.

What are the current treatments for Sleep Paralysis?

In most cases, sleep paralysis occurs so rarely that treatment is not needed. If the cause is known, for example, due to lack of sleep, correcting the cause by getting enough sleep often resolves the condition.

Sometimes, medicines that prevent REM during sleep are prescribed.

In people with mental health conditions, such as anxiety, medicine and behavioral therapy (talk therapy) to help treat the mental health condition may resolve sleep paralysis.
