Sleep Paralysis

Have you ever felt while sleeping that your body is unable to move or make any movement ? Ofcourse, most of us have experienced this thing known as Sleep Paralysis. First of all, let me tell you that in most of cases, Sleep paralysis is common and not a disease or disorder. It is not considered a dangerous health problem but in some cases it can be linked to disorders such as narcolepsy, migraines, anxiety disorders, and obstructive sleep apnea.

Sleep researchers conclude that, in most cases, sleep paralysis is simply a sign that your body is not moving smoothly through the stages of sleep. Rarely is sleep paralysis linked to deep underlying psychiatric problems.

Occurrence :

Sleep paralysis is closely related to the paralysis that occurs as natural part of  REM (rapid eye movement) sleep. Sleep paralysis can occur in two ways : either when the person is falling asleep and is aware while the body shuts down for REM sleep. This condition is known as predormital sleep paralysis. Or it can occur when the person is awakening from a session in which the person becomes aware before the REM cycle is complete and this condition is called postdormital sleep paralysis.

Over the centuries, symptoms of sleep paralysis have been described in many ways and often attributed to an "evil" presence. Hearing of demonic voice when resistance is attempted is commonly experienced during Sleep Paralysis.

How Sleep Paralysis occurs :


In Predormital sleep paralysis (also known as hypnagogic), your body relaxes slowly as you fall asleep. Usually you become less aware, so you do not notice the change. However, if you remain or become aware while falling asleep, you may notice that you cannot move or speak.

 In Postdormital sleep paralysis (also known as hypnagogic), your body alternates between REM (rapid eye movement) and NREM (non-rapid eye movement) sleep during sleep. One cycle of REM and NREM sleep lasts about 90 minutes. NREM sleep occurs first and takes up to 75% of your overall sleep time. During NREM sleep, your body relaxes and restores itself. At the end of NREM, your sleep shifts to REM. Your eyes move quickly and dreams occur, but the rest of your body remains very relaxed. Your muscles are "turned off" during REM sleep. If you become aware before the REM cycle has finished, you may notice that you cannot move or speak.


Causes of Sleep Paralysis :

Though sleep paralysis can occur without a known cause also, but many a times there are some causes linked to it. Some of common causes includes :

• Lack of Sleep
• Change of Sleeping Schedule
• Stress or depression
• Sleeping on the back
• Use of medications or Drugs
• Other Sleep problems such as narcolepsy, migraines, anxiety disorders, and obstructive sleep apnea.

What Can I Do About Sleep Paralysis?

Most people need no treatment for sleep paralysis. There's no need to fear nighttime demons or alien abductors. If you have occasional sleep paralysis, you can take steps at home to control this disorder. Start by making sure you get enough sleep. Do what you can to relieve stress in your life -- especially just before bedtime. Try new sleeping positions if you sleep on your back. And be sure to see your doctor if sleep paralysis routinely prevents you from getting a good night's sleep.
