Sleep Paralysis

Posted on April 11, 2025 by Patrick Hercules

Sleep paralysis is a type of parasomnia that occurs when the body is between stages of sleep and wakefulness lasting for a few seconds to a couple of minutes.

During an episode of sleep paralysis, you are aware of your surroundings but can’t speak or move. You can still move your eyes and breathe. You may also feel:

Fear
Panic
Helplessness
Anxious

When it ends, you may feel confused because you will regain movement of your body as if nothing happened. You can feel nervous about going to sleep after an episode of sleep paralysis, and it can affect how you feel and function during the day.

Sleep paralysis isn’t dangerous, however, it can cause emotional distress during an episode. Some cases of sleep paralysis are linked to other disorders.

You can experience several symptoms during an episode of sleep paralysis either right before falling asleep or as you’re waking up, including:

You can’t move your arms and legs
You can’t speak
Sensations of pressure against your chest or moving out of your own body
Hallucinations, such as a dangerous person in your room
Daytime sleepiness

Symptoms may first appear in childhood or adolescence. Episodes are more frequent in your 20s and 30s.

The exact cause of sleep paralysis is unknown. However, healthcare providers believe it could happen due to the following:

Narcolepsy
Sleep deprivation
An irregular sleep schedule
Obstructive sleep apnea
Mental health conditions such as anxiety, bipolar disorder, post-traumatic stress disorder (PTSD), or panic disorder
Certain medications
Substance use disorder

To diagnose sleep paralysis, healthcare providers can confirm or rule it out after a physical exam and a sleep evaluation. A provider may ask you about the following:

Your symptoms, such as how often you experience sleep paralysis, what it feels like, and when it started
The quantity and quality of sleep you get, such as how many hours you sleep at night and whether you feel tired during the day
Your medical history, including what medications you currently take and whether you smoke, use alcohol, or non-prescribed drugs
Your family history and if you’re aware of any biological family members who experience sleep paralysis

To further diagnose sleep paralysis, a healthcare provider may recommend testing if they suspect certain sleep disorders like narcolepsy. Tests can include:

An overnight sleep study
Multiple sleep latency test (MSLT)

Treatment for sleep paralysis will depend on the reason why you have it. A healthcare provider may recommend the following:

Taking medications that prevent you from reaching the REM stage of sleep
Taking medications to treat an underlying mental health condition or sleep disorder, such as antidepressants
Improving your sleep hygiene
Talking to a mental health provider if you experience frequent stress

There isn’t much you can do to prevent sleep paralysis from happening. However, there are steps you can take to lower your risk.

One of the best ways to avoid sleep paralysis is to improve your quality of sleep. You can do this by:

Having a set sleep schedule with specific times for going to bed and waking up
Creating a comfortable sleep environment that is dark and quiet
Putting phones, tablets, e-readers, and computers away before bedtime
Relaxing before bed by taking a bath, reading, or listening to soothing music

Learning More About Narcolepsy

Posted on December 16, 2020 by Michael Hinck

Narcolepsy is a chronic sleep disorder characterized by overwhelming daytime drowsiness and sudden attacks of sleep. People with narcolepsy fall asleep without warning, anywhere, anytime. When they awaken, they may feel refreshed, but eventually get sleepy again. Narcolepsy can drastically affect a person’s quality of life and can result in physical harm to themselves or others.

There are two forms of narcolepsy: Type 1 narcolepsy is when sudden attacks of sleep are accompanied by a loss of muscle tone. Type 2 narcolepsy occurs with no loss in muscle tone.

In addition to sudden attacks of sleep, some of the signs and symptoms of narcolepsy include:

Decreased alertness and focus – Excessive daytime sleepiness makes it difficult for individuals to concentrate and fully function.
Sudden loss of muscle tone – This condition, called cataplexy can cause a number of physical changes, from slurred speech to complete weakness of most muscles, and may last up to a few minutes.
Sleep paralysis – People with narcolepsy often experience a temporary inability to move or speak while falling asleep or upon waking. These episodes are usually brief, lasting a few seconds or minutes.
Hallucinations – Hallucinations may occur while sleeping or while awake. These hallucinations may be particularly vivid and frightening because the person experiencing them may believe they are reality.

Narcolepsy symptoms typically begin anywhere between ten and thirty years of age. Symptoms may worsen for the first few years and then continue for life. People with narcolepsy may also have other sleep disorders, such as obstructive sleep apnea, restless leg syndrome and even insomnia.

While the exact cause of narcolepsy is unknown, research has revealed that people with type 1 narcolepsy have low levels of the chemical hypocretin, which is an important neurochemical in your brain that helps regulate wakefulness and REM sleep. Those with a family history of narcolepsy have a greater risk of developing it.

Unfortunately, there is no cure for narcolepsy however medications and lifestyle changes can help manage the symptoms. It is recommended that you see a doctor if you experience excessive daytime sleepiness that disrupts your personal life.

Jamaica Hospital’s Sleep Center treats individuals with a wide variety of sleep disorders. Please call 718-206-5916 to schedule an appointment.

Sleep Paralysis

Posted on September 27, 2016 by Xavia Malcolm

Have you ever woken up and found that you were unable to move or speak? Believe it or not, over the centuries some have attributed this symptom to evil or supernatural presences especially when accompanied by hallucinations or a chest-crushing sensation. However, there is a medical explanation and name for this phenomenon. This frightening but perfectly natural occurrence is called sleep paralysis. It is estimated that up four out of every ten people have experienced symptoms associated with the disorder. Studies suggest that as many as fifty percent will experience sleep paralysis at least once in their lifetime.

Sleep paralysis is a term used to describe a variety of symptoms which occur when your body is not moving smoothly through the stages of sleep. It has been found that sleep paralysis most often happens during the REM (rapid eye movement), the phase where your brain is active and vivid dreams occur but your muscles are relaxed or turned off. The state of paralysis happens when a person wakes up before REM is completed. The brain is still actively dreaming but as a response to keep the body from acting out dreams and harming ourselves or others; our voluntary muscles become paralyzed.

According to medicinenet.com, “Sleep paralysis usually occurs at one of two times. If it occurs while you are falling asleep, it’s called hypnagogic or predormital sleep paralysis. If it happens as you are waking up, it’s called hypnopompic or postdormital sleep paralysis.”

Symptoms of sleep paralysis may differ from person to person and may include:

The inability to move or speak immediately after waking up.
Hallucinations- which occur because the brain is still in a state of dreaming.
Chest pressure- which can occur as a result of panicking

Causes of sleep paralysis can be attributed to:

Lack of sleep
Sleep position- It is believed that people who sleep on their backs are more inclined to have symptoms
Extreme fatigue
Use of certain medication
Narcolepsy
Stress
Mental health disorders such as bipolar disorder

Although sleep paralysis is a relatively harmless health condition it is recommended that you consult your physician or a sleep specialist if symptoms are prevalent and disrupting daily activities or the ability to function normally.
