What is Sleep Paralysis and Night Terrors.
Sleep paralysis is when you're temporarily unable to move or speak as you go from sleep to wakefulness, or vice versa. It can last seconds to minutes, during which time you may feel like you are touching, hearing, smelling, or seeing people or things that aren't really there.You may feel anxious, scared, or even like you're going to die (or that you're already dead). You are aware of the experience, but unable to do anything to control it.
Luckily, most people who experience sleep paralysis don't typically have it often. When they do, the cause is usually relatively harmless with no serious risks. However, some conditions that can affect your health may be to blame.
Here's everything you need to know about sleep paralysis, including what causes it and what you can do if it happens to you.
Sleep paralysis can occur when you're waking up, or what's called a hypnopompic state. It can also happen when you're falling asleep, or in a hypnagogic state. The latter is more common in people with narcolepsy, a sleep disorder that makes you sleep too much.
You're more likely to experience sleep paralysis closer to the morning. That's when rapid eye movement (REM), the sleep stage associated with vivid dreaming, occurs. It also happens more often when you sleep on your back
Common features of sleep paralysis include:
Limited eye movement
Sense of an evil presence or impending doom
Hallucinations:
For example, having a feeling of being touched, hearing voices in the room, or seeing people or faces by the bed.
Feeling short of breath or pressure on your chest:
It may seem like someone is standing or sitting on the chest, though your breathing is not actually being affected.
For example, you may feel like someone is standing over you. You try to move your head to look, but you can't. It feels like someone—or something—is holding you down. You feel like you can't breathe.
You may try to thrash your arms and legs, but you're frozen in place. Sheer panic washes over you. You may even fear like your life is in danger.
While many people have scary sensations, it's also possible to have pleasant ones.
Common symptoms of sleep paralysis are the feeling that you're not able to move or speak, the presence of something or someone else in the room, hearing noises or voices that aren't there, or feeling like someone is touching you.
Sleep paralysis usually happens to people in their 20s and 30s, but some have their first episode as teenagers.
People with certain medical or mental health conditions—like narcolepsy or sleep apnea—are more likely to have sleep paralysis.
Sleep paralysis has a strong genetic component and may run in families, according to a 2011 review of several studies.
Sleep paralysis is relatively common. A) 2011 review reported that about 7% of people experienced sleep paralysis at least once.
The study also noted that it affects some people more than others. For example, 28% of students and 34% of people with panic disorder have reported episodes of sleep paralysis.
B) 2018 study found that student-athletes regularly reported sleep paralysis.
The study also found students with depression had higher instances of sleep paralysis.
Causes of sleep paralysis
Sleep deprivation, stress, and a disrupted sleep schedule can trigger sleep paralysis.
Anxiety disorders also have a strong link, likely because they lead to insomnia or lighter, fragmented sleep.
2016 review found that sleep paralysis occurs with disruption of rapid eye movement (REM), or dream sleep.6 Although specific triggers play a role, some people believe it's related to a problem with REM regulation. During this phase of sleep, your body relaxes so that it doesn't physically act out dreams.
This type of relaxation can cause temporary paralysis if it happens while a person is awake. Other elements of vivid dream sleep can continue as you wake up and also occur with disrupted REM.
Obstructive sleep apnea can disrupt your breathing. This causes you to wake up throughout the night, resulting in an episode of sleep paralysis.7 This explains why someone who sleeps on their back is more likely to have sleep paralysis.
Your condition may have an underlying cause, such as sleep apnea if you have symptoms like:
Snoring
Teeth grinding (bruxism)
Pauses in breathing
Gasping or choking
Daytime sleepiness
Frequently waking to urinate at night (nocturia)
In rare cases, another disorder mimics sleep paralysis. One example is a focal epileptic seizure. video electroencephalogram (EEG) can help differentiate between the two. An EEG is a test that records your brain's electrical activity.
disruption in REM sleep (deep, rapid eye movement sleep) is the cause of sleep paralysis in most cases. But if you have other symptoms, too, it can be a sign of a related condition, like sleep apnea, anxiety disorder, or narcolepsy.
Causes and Risk Factors of Sleep Paralysis
Treatment
Sleep paralysis ends within a few minutes, either when you go back to sleep or fully wake up. Treatment is not typically needed and most people feel like they can cope after they know they're not actually in danger.
If you're prone to episodes of sleep paralysis, improving your sleep hygiene can often help. While it sounds like a sleepy shower, sleep hygiene actually refers to healthy habits that help you fall into a deep sleep. Some of these include:
Get enough sleep
Avoid alcohol and caffeine before bed
Manage your stress
How to Fix Your Sleep Hygiene
In rare cases, people suffer from repeated episodes and feel like they can't handle the psychological distress.
Medicine that suppresses the REM cycle of sleep sometimes helps. This includes selective serotonin receptor inhibitors (SSRIs) and tricyclic antidepressants (TCAs).6
Ask your healthcare provider to evaluate you to address any sleep, mental health, or other medical disorders that can disrupt sleep, like sleep apnea or narcolepsy.
If you have multiple or recurring episodes of sleep paralysis and these strategies don't help, your healthcare provider might refer you to a board-certified sleep specialist for an evaluation that will likely include a sleep study.
Coping
Some people find that mindfulness meditation and muscle relaxation exercises help them cope with sleep paralysis.8
When you experience sleep paralysis, focus on relaxing your mind. Tell yourself that:
You know what's happening
It's not real
You're not in any danger
The sleep paralysis will end soon
Some people even like to engage in the experience. They'll pretend they're an actor in a scary movie. This gives them a sense of control over something that otherwise makes them feel powerless.
If you can reassure and distract yourself enough to fall back asleep, the experience will quickly end.
If sleep paralysis often happens to you, there are ways you can learn to cope with it. First, rest assured that it's usually harmless. Focus on improving your sleep habits, practice mindfulness exercises, or even pretend you're in a scary movie and engage in the experience.
Summary
Sleep paralysis is somewhat common in adults but especially affects students and people with panic disorders. It happens when the transition to sleep or awakening is disrupted, and there's an interruption in your REM sleep.
Many times people experience hallucinations that they can see, hear, smell, or feel. Most people don't like the experience and often feel scared. But usually, sleep paralysis is harmless.
If it's really bothering you or if you have other symptoms of sleep disorders, see your healthcare provider or a sleep specialist.
FREQUENTLY ASKED QUESTIONS
Why does it feel like I can’t move when I wake up?
You might be experiencing hypnopompic paralysis.9 It happens as your brain transitions from sleep to waking up, or the other way around. Get enough rest and treat any underlying anxiety to keep it from repeating. You have nothing to worry about if it doesn't happen often, but talk to your healthcare provider if it does.
Can too little sleep cause hallucinations?
Yes. Without enough sleep, your brain doesn't function as well. You might see, feel, hear, smell, or even taste things that aren't there.10 Some people have these hallucinations right after they wake up or when they fall asleep after a long period of not getting enough sleep
