Quick answer
What is Sleep paralysis?
Sleep paralysis is a temporary inability to move or speak that happens as a person is falling asleep or, more often, waking up. During dreaming (REM) sleep, the body is naturally "switched off" (paralysed) so we do not act out our dreams; in sleep paralysis, a person becomes aware while this normal paralysis is still present, so they are conscious but unable to move for a short time — usually seconds to a couple of minutes.
- How it is treated: For most people, sleep paralysis needs no specific treatment, and reassurance that it is harmless and common is the most important part of care — understanding what is happening (that it is a brief overlap of dreaming sleep and wakefulness, not a sign of anything dangerous) reduces the fear.
- Self-care: Getting enough regular sleep, keeping a consistent sleep schedule, managing stress, and avoiding sleeping on the back all reduce sleep paralysis.
- When to seek help: Sleep paralysis usually needs no medical attention.
What it is
Sleep paralysis is a temporary inability to move or speak that happens as a person is falling asleep or, more often, waking up. During dreaming (REM) sleep, the body is naturally "switched off" (paralysed) so we do not act out our dreams; in sleep paralysis, a person becomes aware while this normal paralysis is still present, so they are conscious but unable to move for a short time — usually seconds to a couple of minutes. It can be frightening, particularly as some people also experience vivid, dream-like hallucinations during it (such as a sense of a presence in the room, pressure on the chest, or seeing or hearing things), and a feeling of fear. Despite being alarming, sleep paralysis is harmless and does not cause any physical harm. It is common — many people experience it at least once. It is more likely with sleep deprivation, irregular sleep, stress, and sleeping on the back, and can be associated with narcolepsy in some people.
How it is treated
For most people, sleep paralysis needs no specific treatment, and reassurance that it is harmless and common is the most important part of care — understanding what is happening (that it is a brief overlap of dreaming sleep and wakefulness, not a sign of anything dangerous) reduces the fear. Improving sleep habits often reduces how often it happens: getting enough regular sleep, keeping a consistent sleep schedule, managing stress, and avoiding sleeping on the back can all help. During an episode, trying to stay calm and knowing it will pass within a short time helps; some people find that trying to move a small part of the body (like a finger or toe) or focusing on their breathing helps it end. If sleep paralysis is frequent, distressing, or associated with other symptoms — particularly excessive daytime sleepiness or suddenly falling asleep (which could suggest narcolepsy) — it is worth seeing a doctor for assessment. The reassuring message is that sleep paralysis is common and harmless, and usually improves with better sleep habits and understanding what it is.

Getting enough regular sleep, keeping a consistent sleep schedule, managing stress, and avoiding sleeping on the back all reduce sleep paralysis. During an episode, staying calm, knowing it will pass, and trying to move a finger or toe can help it end.
When to get help
When to see a doctor
Sleep paralysis usually needs no medical attention. See a GP if it is frequent or distressing, or — importantly — if it comes with excessive daytime sleepiness or suddenly falling asleep during the day, which could suggest narcolepsy and needs assessment.
