Sleep Paralysis

Have you ever felt paralysed while waking up or falling asleep? This terrifying experience is known as sleep paralysis, a common but often misunderstood sleep disorder. Sleep or night paralysis occurs when a person's mind is awake, but their body remains in a state of paralysis. This condition can cause intense fear and anxiety, leaving many people searching for answers about its causes and treatments. 

Sleep paralysis affects people of all ages and backgrounds. Some experience it frequently, while others only encounter it once or twice in their lives. This blog delves into the symptoms, causes, and remedies for sleep paralysis. 

What is Sleep Paralysis? 

Night paralysis is a peculiar condition that occurs when a person is conscious but unable to move. This phenomenon occurs during the transition between stages of wakefulness and sleep, leaving individuals temporarily immobilised for a few seconds to a few minutes. During these episodes, people often experience a sense of pressure or choking, accompanied by vivid hallucinations. 

This unsettling experience is a type of parasomnia, which refers to abnormal behaviours or experiences during sleep. Although it looks like a frightening situation, sleep paralysis is generally not a big concern. 

Types of Sleep Paralysis 

Sleep paralysis manifests in two primary forms: isolated sleep paralysis and recurrent sleep paralysis. Each type has special characteristics and implications, such as: 

• Isolated sleep paralysis occurs when an individual experiences episodes of sleep paralysis without any other signs of sleep disorders or narcolepsy. This type is generally less severe and may happen sporadically throughout a person's life. 
• On the other hand, recurrent sleep paralysis involves multiple episodes over time. This type can be more distressing due to its repetitive nature. 
• In some cases, recurrent sleep paralysis is associated with narcolepsy, a neurological disorder characterised by sudden episodes of deep sleep at any time. 

Symptoms of Sleep Paralysis 

Sleep paralysis can be an unsettling experience, characterised by a range of symptoms that occur either when a person falls asleep or wakes up. 

One of the most common sleep paralysis symptoms is the inability to move one's arms or legs. This paralysis extends to the ability to speak, leaving individuals feeling trapped in their bodies. Other symptoms are: 

• Sensations of pressure against their chest, lead to a feeling of suffocation. 
• In some cases, individuals may have an out-of-body experience, feeling as if they are separate from themselves. 
• Hallucinations are another significant aspect of sleep paralysis, occurring in approximately 75% of episodes. 
• The emotional trauma caused by sleep paralysis can be huge. Individuals often report feeling fear, panic, and helplessness. 

Causes of Sleep Paralysis 

The exact cause of this sleep-related condition is unknown. However, researchers have identified some factors that may contribute to its occurrence. 

Sleep paralysis happens when a person regains awareness while entering or exiting rapid eye movement (REM) sleep, but their body hasn't entirely switched sleep phases or woken up. 

Doctors have noticed that sleep paralysis can occur in association with various conditions and circumstances: 

• Narcolepsy 
• Not getting enough sleep 
• Obstructive sleep apnea 
• Mental health conditions (anxiety, bipolar disorder, post-traumatic stress disorder (PTSD), and panic disorder) 
• Certain medications, such as those used to treat ADHD 
• The consumption of certain substances can affect sleep patterns, thus increasing the risk of sleep paralysis. 

Risk Factors for Sleep Paralysis 

Some risk factors associated with this unsettling condition, such as: 

• Family history of sleep paralysis 
• Exposure to traumatic events 
• Inadequate sleep and irregular sleep schedules 
• Sleeping on one's back 
• Substance use, including alcohol consumption 

Complications of Sleep Paralysis 

While sleep paralysis is generally considered a benign condition, it can affect an individual's overall well-being. The complications associated with sleep paralysis extend beyond the immediate experience of the episodes themselves, including: 

• Underlying Conditions: Sleep paralysis can indicate more serious issues like narcolepsy or panic disorder. 
• Psychological Impact: Fear from sleep paralysis can lead to anxiety disorders, creating a cycle of anxiety and increased sleep disturbances. 
• Sleep Quality: Poor sleep quality from sleep paralysis can worsen the condition, creating a cycle of disturbances. 
• Daily Life Effects: Persistent sleep disturbances and anxiety can affect work performance, social relationships, and overall quality of life. 
• Anxiety: The fear of experiencing sleep paralysis may lead to sleep anxiety, further aggravating sleep problems. 

Diagnosis 

The diagnosis of sleep paralysis involves a comprehensive evaluation by doctors. To confirm or rule out sleep paralysis, doctors typically conduct a physical exam and a sleep evaluation. 

If a sleep disorder such as narcolepsy is suspected, doctors may recommend additional testing, including: 

• Overnight Sleep Study (Polysomnogram): This test monitors breathing, heartbeat, and brain activity during sleep. 
• Multiple Sleep Latency Test (MSLT): This test measures how quickly a person falls asleep and the type of sleep experienced during a nap. It helps uncover issues such as narcolepsy. 

Several questionnaires have been developed to aid in the evaluation of sleep paralysis. These include the Sleep Paralysis Experiences and Phenomenology Questionnaire (SP- EPQ) and the Unusual Sleep Experiences Questionnaire (USEQ). 

Sleep Paralysis Treatment 

For individuals experiencing frequent sleep paralysis, doctors may recommend the following approaches: 

• Medication: In some cases, doctors may prescribe medicines that prevent reaching the REM stage of sleep or treat underlying mental health conditions or sleep disorders. 
• Improving Sleep Hygiene: Enhancing sleep habits has an impact on preventing sleep paralysis and improving overall rest. These involve: 
  • Following a consistent bedtime routine 
  • Avoiding caffeine and alcohol in the evening 
  • Refraining from screen use at least an hour before sleep 
  • Aiming for seven to nine hours of night sleep daily 
• Stress Management: Cognitive behavioural therapy could help individuals relax, especially if they experience anxiety and stress around bedtime. 
• Some techniques may help individuals break out of episodes: 
  • Focusing on slowly moving one body part at a time, such as a finger or toe 
  • For people with narcolepsy, following specific steps during sleep paralysis may be helpful: 
    • Reminding oneself that the experience is temporary 
    • Focusing on a positive object or memory 
    • Relaxing muscles 

When to See a Doctor 

It's essential to consult a doctor if: 

• Sleep paralysis episodes cause significant anxiety 
• Excessive daytime fatigue 
• These episodes consistently disrupt sleep patterns 

Prevention of Sleep Paralysis 

To improve sleep quality and potentially decrease the occurrence of sleep paralysis, individuals can: 

• Establish a consistent sleep schedule 
• Create an optimal sleep environment 
• Limit electronic device use before bedtime 
• Practise relaxation techniques 
• Trying new sleeping positions may reduce the frequency of episodes. 
• Ensure adequate sleep 

Conclusion 

Sleep paralysis is not typically harmful, but it can indicate underlying sleep disorders or mental health conditions. If sleep paralysis causes significant distress or disrupts daily life, it's crucial to consult a doctor. They can help identify the reason for sleep paralysis and provide tailored strategies to manage symptoms. With the right approach, individuals can improve their sleep quality and minimise the impact of sleep paralysis on their overall well-being.
