Understanding sleep paralysis and what causes it

Have you ever heard of sleep paralysis? If you’re a fan of the reality show Keeping Up With the Kardashians, the issue was brought to the forefront on one episode focused on Kendall Jenner.

The reality star and model revealed this month that she’s afraid to fall asleep. She explained that she wakes up in the middle of the night, and while her mind is awake, she can’t move her body. On the show, she described the events: “I’m freaking out because recently I wake up in the middle of the night and I can’t move,” Kendall said.

So what is sleep paralysis, and what causes it?

“Isolated sleep paralysis is essentially rapid eye movement (REM) sleep intruding into wakefulness,” says Matt Balog, a pediatric clinical sleep educator at Advocate Children’s Hospital in Park Ridge, Ill. “During REM sleep, most of our muscles become paralyzed. This temporary paralyzed state is a good thing, as having the ability to move during REM sleep can cause physical injury to you or your partner. But an episode of isolated sleep paralysis can be extremely frightening, as a person cannot move, and some accessory breathing muscles may still be paralyzed so breathing is more difficult than usual, as well.”

Balog also says these episodes may include some auditory and visual hallucinations. But the hallucinations are products of REM sleep and not generally a sign of any psychiatric disorder.

Balog says sleep paralysis is actually common in the general population. One systematic review found that 7.6 percent of individuals experience sleep paralysis at one time or another. The rates are higher for students; 28.3 percent of them have had sleep paralysis at some point.

And other research has revealed that for young adults who have an anxiety disorder, 20 percent may experience an isolated episode.

So what can someone experiencing sleep paralysis do?

“In most cases, isolated sleep paralysis is provoked by fragmented sleep, sleep deprivation, excessive sleepiness, stress, an irregular sleep-wake schedule or as a result of another sleep disorder,” says Balog.

Because of this, it can be helpful for someone who experiences an episode to examine their sleep habits. “Basic sleep hygiene and relaxation techniques can help lessen the frequency of these events,” he advises.

Balog says generally speaking, someone should not be concerned if they have experienced an episode or two of sleep paralysis. But if the episodes are happening frequently and are accompanied by auditory or visual hallucinations on a regular basis, you should see a sleep professional.

  1. I have been experiencing this since childhood. You described it perfectly. It happens more often when I have been sleep deprived or experiencing stress. The hardest thing while going through an episode is not knowing how long you have to lay and be awake in the mind while waiting for your body to awaken. This is what makes it frightening.

  2. This paralysis used to plague me years ago. I finally was able to wake my self during an episode by shaking my feet this always brought me out of it. It takes concentration. And yes it was more frequent during overtired evenings. My episodes were accompanied by a buzzing in my head. Shake those feet and legs when it starts. I no longer get these episodes, i hope i never do again.

  3. Hi Michelle and Gail I’ve been getting sleep paralysis for at least the last 10 years maybe more!still do but I’m the same as Gail now I actually don’t fear it anymore and can wake myself up gradually by controlling it and not panicking!the last year or so haven’t got in once I used to get it every few weeks sometimes every few days!question for yous!did yous ever wake up from it and feel and evil presence in the room?i did once and to be honest was even worse than the first time I got sleep paralysis!

  4. Nice thing that Kendal Jenner brought the condition up on a wide
    platform. We need to realize that this is a serious problem that needs a
    solution, otherwise this will lead to greater problems. I would totally blame
    such a disorder on the lifestyle that we follow. A stressful mind can lead to
    more grave problems than this one.
