Sleep paralysis is a temporary state of mental wakefulness and physical paralysis. Sleep paralysis episodes typically occur just before or after the [rapid eye movement](https://www.masterclass.com/articles/rem-sleep-guide) stage of sleep. This overlap of wakefulness and REM sleep can create the sensation of hallucinations. 

Sleep paralysis is a parasomnia disorder, a type of sleep disorder. (Other types of parasomnia include [sleepwalking](https://www.masterclass.com/articles/somnambulism-explained) and night terrors.) The experience of sleep paralysis often incites hypnagogic hallucinations, which occur while falling asleep, or hypnopompic hallucinations, which happen when waking up. 

Vestibular-motor hallucinations produce out-of-body sensations and dreamlike feelings of motion. Some people experience sleep paralysis with intruder hallucinations that mimic nightmares and often involve the sense that someone is lurking nearby. Sleep paralysis can also incite incubus hallucinations, which create a perceived pressure in the chest area that can feel like suffocation.

Sleep paralysis and cataplexy are sleep disorders that can cause atonia, a temporary loss of muscle control. Cataplexy is a chronic syndrome commonly linked to the neurological disorder known as narcolepsy. A person can experience an episode of sleep paralysis without being narcoleptic or cataplectic. However, repeated sleep paralysis episodes may be an early sign of narcolepsy. Consult a neurologist for a proper diagnosis.

The scientific community has not reached a consensus on what causes sleep paralysis, although several conditions correlate with the phenomenon:

- __Obstructive sleep apnea (OSA)__: People with sleep apnea often experience sleep paralysis. [Sleep apnea](https://www.masterclass.com/articles/sleep-apnea-guide) is a sleep disorder that occurs when a person’s upper airway becomes blocked, triggering abnormal breathing during sleep. 
- __Mental health conditions__: Sleep paralysis is more common in psychiatric patients, particularly those with post-traumatic stress disorder (PTSD), severe anxiety disorders, and panic disorders.
- __Irregular sleep cycles__: A lack of sleep can trigger sleep paralysis. Irregular work schedules, frequent jet lag, and medications that cause routine sleep deprivation put a person at greater risk for sleep paralysis. 

If you experience sleep paralysis, consider reaching out to a sleep care specialist to conduct a sleep study.

Health care professionals may treat severe cases of sleep paralysis with antidepressants, but the first step you can take to prevent sleep paralysis is to improve your overall [sleep hygiene](https://www.masterclass.com/articles/sleep-hygiene-tips). Follow these steps to build healthy sleep habits:

- __Keep a consistent sleep schedule__. Your body's [circadian rhythm](https://www.masterclass.com/articles/circadian-rhythm-explained) is programmed to sleep and wake up at the same time every night. Keep a routine of sleep patterns for maximum sleep quality.
- __Avoid caffeine before bed__. Whenever possible, refrain from drinking caffeine within four hours of your bedtime to get better sleep.
- __Avoid excessive alcohol consumption.__ Alcohol can knock you out quickly, but it can be ruinous for a good night's sleep. To sleep soundly through the night, limit yourself to two alcoholic beverages or fewer, and not too close to your bedtime.
- __Limit nighttime exposure to screens__. The [blue light](https://www.masterclass.com/articles/blue-light-effects-on-sleep) that radiates from electronic screens prevents your body from releasing the sleep hormone melatonin, which throws off the timing of your circadian rhythm.
- __Keep your bedroom cool__. The human body sleeps soundly at relatively cool temperatures. Turn down the thermostat to around 68 degrees Fahrenheit for a better night's sleep.
