What is Sleep Paralysis?
Sleep paralysis is a temporary state where you're conscious but unable to move or speak when falling asleep or waking up. It usually lasts from a few seconds to a few minutes.
When it occurs
Mainly happens when falling asleep (hypnagogic) or waking up (hypnopompic)
Duration
Most episodes last from a few seconds to 2 minutes
Prevalence
About 8% of the population experiences it at least once in their lifetime
Associated symptoms
May be accompanied by hallucinations, pressure sensation, and fear
Scientific Causes of Sleep Paralysis
Sleep paralysis occurs during the transition between REM sleep and wakefulness.
Delayed REM atonia release
During REM sleep, the brain paralyzes muscles to prevent acting out dreams. Sleep paralysis happens when you wake but this paralysis hasn't released
Sleep deprivation
Lack of sleep causes irregular REM cycles and increases the chance of sleep paralysis
Irregular sleep patterns
Inconsistent sleep schedules disrupt sleep stage transitions, leading to sleep paralysis
Stress and anxiety
Mental stress and anxiety decrease sleep quality and trigger sleep paralysis
Sleeping position
Sleep paralysis occurs more frequently when sleeping on your back (supine position)
Risk Factors for Sleep Paralysis
The following factors can increase your risk of experiencing sleep paralysis.
Sleep disorders
Having other sleep disorders like narcolepsy or insomnia
Shift work
Irregular work patterns that disrupt your day-night cycle
Jet lag
Period of adjusting to new time zones after travel
Substance effects
Influence of certain medications or alcohol
Mental health
Depression, PTSD, or generalized anxiety disorder
Family history

How to Prevent Sleep Paralysis

Remember that this is temporary and will end soon
Try small movements
Focus on moving small parts like fingers or toes first
Move your eyes

Instead of resisting, relaxing your body may help it end faster
