What is Sleep Paralysis?
Sleep paralysis is a temporary inability to move or speak that happens as someone is falling asleep or waking up, sometimes accompanied by vivid, frightening hallucinations or a sense of pressure on the chest. It happens because the natural muscle paralysis that occurs during dream sleep briefly persists into a waking state.
While frightening, sleep paralysis is not dangerous and usually lasts only a few seconds to a couple of minutes. It's fairly common, especially in people who are sleep-deprived, under stress, or have irregular sleep schedules, and typically improves by addressing sleep habits.
02 · Understand
Clinical context
It's a harmless, if frightening, sleep phenomenon
Sleep paralysis happens because the brain's dream-sleep muscle paralysis briefly overlaps with waking consciousness — understanding this can itself reduce some of the fear associated with the experience.

Practical steps
It Usually Passes Within a Minute or Two
While sleep paralysis can feel alarming in the moment, it typically resolves on its own within a short time — trying to stay calm, rather than fight it, often helps it pass more quickly.
- 1Maintain a regular sleep schedule.Consistent sleep and wake times reduce the likelihood of episodes.
- 2Prioritise enough sleep.Sleep deprivation is a common trigger for sleep paralysis.
- 3Manage stress levels.High stress can increase the frequency of episodes for some people.
- 4Try sleeping on your side.Some people find sleep paralysis is more common when sleeping on their back.
- 5Stay calm during an episode.Reminding yourself it will pass, and focusing on small movements like wiggling a finger, can help end the episode sooner.
