Fear not, for this blog has got you covered! We'll delve into everything concerning sleep paralysis, including its symptoms, causes, and what you can do to stop it from being a recurring event. So, sit back, relax, and let's tackle this sleep demon once and for all:
What is Sleep Paralysis?
Sleep paralysis is a temporary condition that can leave you feeling powerless and vulnerable. It occurs as you transition between sleep and wakefulness, leaving you unable to move or speak for seconds or minutes. During this time, you may experience sensations that feel very real, such as touching, hearing, smelling, or seeing people or things that don't actually exist.
For many, sleep paralysis can be a frightening experience, often accompanied by symptoms like anxiety or a sense of impending doom. While these episodes can be unsettling, they are usually infrequent and pose no long-term risks. In some cases, underlying health conditions may contribute to the cause of sleep paralysis, but these are generally manageable (Suni, 2020).
What Are the Underlying Causes of Sleep Paralysis?
Sleep paralysis is a common phenomenon often triggered by insufficient sleep and stress. Disruptions to your sleep schedule can interfere with your regular sleep cycle, making you more likely to experience sleep paralysis. Likewise, high levels of stress can also contribute to this condition!.
Other significant underlying causes of sleep paralysis include:
Narcolepsy
Narcolepsy is a chronic disorder that affects a person's ability to sleep and wake up. It is a neurological condition that is characterized by the rapid onset of rapid eye movement (REM) sleep. The most common symptom of narcolepsy is excessive daytime sleepiness (EDS), where the person experiences a strong urge to sleep during the day, even if they have had a good night's sleep.
Additionally, people with narcolepsy have episodes of uncontrolled sleep attacks, cataplexy, sleep paralysis, and hallucinations (Liu et al., 2018).
With two types of narcolepsies - type 1 and type 2, it is essential to understand the distinction between the two.
Type 1 narcolepsy involves narcolepsy with cataplexy, while type 2 narcolepsy is characterized by narcolepsy without cataplexy.
Unfortunately, nearly 50% of people experience symptoms of narcolepsy during their teenage years. This is particularly concerning as narcolepsy can significantly impact social and academic performance. The condition is also linked to the loss of neurons that produce orexin, a neurotransmitter essential for regulating wakefulness (Doctors, 2023).
Although type 1 narcolepsy is considered an autoimmune disorder that is triggered by an infection, the cause of type 2 narcolepsy still remains unknown.
Shift Work-Related Sleep Disorders
Many experiences disrupted sleep cycles throughout our lives, whether it's due to work, stress, or other factors. However, the consequences can be particularly challenging for those working rotating shifts like early morning, night, and afternoon shifts.
In fact, according to recent data published in Pubmed, about 12% of nurses suffer from a sleep disorder called shift work sleep disorder, which often leads to sleep paralysis. This can cause multiple symptoms, including excessive sleepiness and difficulty sleeping (Troy, 2020).
Sleep Deprivation
Many people suffer from sleep deprivation, which can have serious consequences. From voluntary sleep deprivation to circadian clock disorders, there are many reasons why individuals may not be getting the sleep they need to function properly.
Lack of sleep can result in various problems, such as impaired judgment, increased accident risk, and lack of hand-eye coordination. For those who suffer from sleep deprivation, disrupting their circadian rhythm can lead to fatigue and extreme daytime sleepiness (Sharpless & Barber, 2011).
Symptoms Related to Sleep Paralysis
If you've dealt with sleep paralysis, you may have wondered, 'Is sleep paralysis life-threatening?' For those who may not know, common symptoms of sleep paralysis include:
- Inability to move or speak
- Difficulty breathing or a sensation of choking
- A heavy pressure on the chest
- Distorted or altered perceptions
- A sense of fear or dread
- Muscle aches and migraines
- Excessive sweating
- Heighted anxiety
- A feeling of impending death
What Are the Different Types of Sleep Paralysis?
Ready for a spine-tingling fact? Sleep paralysis, a temporary loss of muscle control known as muscle atonia, is a real phenomenon—and there are not one, but TWO types! Read on to learn more about this eerie condition.
Solitary Sleep Paralysis
Sleep paralysis is a strange and unsettling experience that can happen to anyone. Solitary sleep paralysis, where you're aware of your surroundings but unable to respond, typically affects those without underlying medical conditions like narcolepsy. It often occurs during adolescence and while lying on your back. Along with paralysis, it can cause vivid, disturbing hallucinations (Suni, 2020).
A recent study published in the National Library of Medicine found that between 2.2% and 39.6% of non-clinical samples, and 7.4% to 50% of clinical samples, experience Solitary sleep paralysis, often linked to panic attacks (Sharpless & Barber, 2011). Episodes usually last around six minutes, leaving individuals disoriented, though it’s reassuring to know that most people experience only occasional occurrences.
Persistent Sleep Paralysis
Persistent sleep paralysis is a benign parasomnia characterized by repeated episodes of isolated sleep paralysis. A study published in the National Library of Medicine found that this condition affects 7% of students and 28% of females, with onset typically occurring during adolescence and being more common in women.
Although the symptoms can be distressing, they are generally not harmful. Common symptoms include vivid hallucinations and a feeling of pressure on the chest, often accompanied by sensations of being strangled (Sehgal & Mignot, 2011). While these experiences can be frightening, effective treatments are available to help manage persistent sleep paralysis.
What Sensation Does Sleep Paralysis Lead to?
Sleep paralysis is a terrifying experience that leaves many feelings helpless and afraid. During an episode, you're fully conscious but unable to move, triggering intense panic and fear. In addition, sufferers often experience hallucinations and unsettling sounds, which amplify the sense of dread.
But is sleep paralysis life-threatening? While it’s not directly fatal, the psychological impact can be significant, leading to long-term emotional distress (Liu et al., 2018).
Below is an overview of the different types of delusions people may experience during an episode:
Intruder Hallucinations
Intruder hallucinations, often characterized by the sense of an evil presence, are commonly linked to sleep paralysis. These hallucinations can evoke both fear and auditory or visual distortions.
While the exact cause remains debated, scientists suggest these hallucinations may stem from a hypervigilant state in the midbrain. Research also indicates that the superior parietal lobule, a brain region responsible for sensory processing and attention, could play a key role in triggering these unsettling experiences (American Sleep Association, 2017).
For anyone who has found themselves lost in the grip of an intruder hallucination, the experience may be frightening and confusing.
Chest Pressure Hallucinations
Have you ever felt as though something, or someone was pressing down on your chest while you sleep? This terrifying sensation is known as chest pressure hallucination or incubus hallucination.
Often linked to sleep paralysis, it occurs when the body temporarily loses the ability to move during the REM stage of sleep. During this time, reduced respiratory muscle activity can cause difficulty breathing or chest pain.
Scientists believe this is due to the inhibition of motor neurons, which decreases activity and can trigger respiratory-related sensations during an incubus hallucination. While the experience can be frightening, it's important to remember that it is temporary and can be managed with proper treatment (Heavner, 2017).
V-M Hallucinations
Have you ever felt like you were flying or floating, even though your feet were firmly on the ground? While it may sound like something out of a sci-fi movie, this sensation is real for those experiencing a vestibular motor hallucination.
Unlike other hallucinations, this phenomenon creates an out-of-body experience that feels almost tangible. Imagine the sensation of weightlessness as you soar through the air, free from the fear of falling (Doctors, 2023).
For many, this surreal experience is hard to describe, but those who have had vestibular motor hallucinations often report it as one of the most awe-inspiring moments of their lives.
What is the Probability of Sleep Paralysis?
Sleep paralysis is a common phenomenon affecting approximately 7.6% of people worldwide. It typically begins during adolescence and can occur at the onset or offset of sleep.
The condition is believed to be caused by the inhibition of motor neurons during REM sleep, involving the pons and ventromedial medulla. These areas use chemicals like alpha-aminobutyric acid and glycine to induce temporary paralysis (Denis, 2018)
Those who experience sleep paralysis are often accompanied by a range of unsettling symptoms, including chest pain, shortness of breath, choking sensations, heart palpitations, trembling, sweating, and nausea.
Many sufferers also report auditory hallucinations, further intensifying the disorienting nature of the experience.
Wrapping Up
Have you ever experienced sleep paralysis and questioned yourself, can sleep paralysis kill you? It can be a scary and overwhelming experience, but there is some good news. Despite what you may have heard, sleep paralysis is not life-threatening. This condition, where you cannot move or speak during the transition between sleep and wakefulness, poses no immediate danger to your health.
That being said, it can be incredibly stressful and distressing to go through. If you're looking for ways to lessen the frequency of these episodes, implementing lifestyle changes and habits may help. It's also important to stay calm during an episode, take slow deep breaths, and try to wiggle your fingers or toes to snap out of it.
