Yoga nidra is a guided rest you do lying completely still: a voice leads your attention slowly around your body, then to your breath and a few simple images, while you stay just on the edge of sleep. There are no poses to hold. For sleep, you do it in bed with the lights low and let yourself drift off at the end if sleep comes. It is often called "yogic sleep", and some people call the same kind of practice non-sleep deep rest. Below is what happens in a session, a 15-minute version for tonight, and a note on the evidence.

What is yoga nidra?

Yoga nidra is a form of guided relaxation from the yoga tradition. You lie on your back, or on your side if that is more comfortable, and follow instructions without moving. The glossary puts it simply: a practice in which a voice leads you through a body scan and imagery, usually for 20 to 30 minutes of deep rest.

It is close to a body scan meditation, with a few extra steps. Unlike most meditation, you are not trying to stay alert; the body rests while a thread of attention follows the voice.

What happens in a yoga nidra session?

Teachers vary, but most sessions follow a similar order:

  1. Settling. Lie down, get comfortable, and agree with yourself not to move.
  2. An intention. A short, positive sentence you repeat silently, such as "I can rest now". It is sometimes called a sankalpa.
  3. Moving round the body. The voice names parts of the body one by one, quickly: right thumb, first finger, second finger… You simply notice each one as it is named.
  4. The breath. You watch the breath, sometimes counting breaths backwards from a number.
  5. Opposites. You recall feelings like heavy and light, or warm and cool, one after the other.
  6. Images. A few short pictures: a candle, a quiet beach, a path through trees.
  7. Return. You repeat the intention, then either come back slowly or, at bedtime, let sleep take over.

How do I do yoga nidra for sleep?

A recording helps, because it is hard to guide yourself and relax at once, but the short version below works from memory.

A 15-minute version for bed

  • Lights low, phone face down. Lie on your back with a pillow under your knees, or on your side with one between them. Get warm; your body cools as you relax.
  • Three slow breaths with a longer out-breath. Then let the breathing go.
  • Your intention, three times, silently.
  • Round the body, slowly. Right foot, right ankle, right knee, right hip. Left foot, left ankle, left knee, left hip. Hands, arms, shoulders. Back, belly, chest. Neck, jaw, eyes, forehead. Just notice each place for a breath or two.
  • Count down. Count breaths backwards from 27. If you lose count, start again at 27.
  • Heavy, then light. Feel the body heavy on the mattress for a few breaths, then light, then heavy again.
  • One picture. A place where you have felt calm. Stay there.
  • Your intention again, and then nothing. Let yourself sleep.

If thoughts pull you away, that is normal; come back to the next body part or the next number. If you feel light-headed or uneasy, open your eyes, take a normal breath, and stop for tonight.

Is yoga nidra the same as sleep?

No. You are resting, not sleeping, and it does not replace a night's sleep. At bedtime the line blurs on purpose. In the daytime, stay with the voice so you don't nap too long.

What does the research say?

Research on yoga nidra itself is still small and early, so it is fair to call it promising rather than proven. The wider picture comes from the NCCIH, which reviews mind and body approaches for sleep: relaxation techniques on their own have a small amount of low-quality evidence for insomnia, and yoga may help sleep quality but not necessarily insomnia. The most strongly recommended treatment for long-term insomnia is cognitive behavioural therapy for insomnia (CBT-I), which often includes relaxation as one part.

So yoga nidra may help you wind down, and the NCCIH says relaxation techniques are generally considered safe. If sleep problems have lasted for months, the NHS suggests seeing a GP. If lying still with your eyes closed brings up difficult memories or feelings, keep your eyes open, shorten the practice, and talk to a doctor or counsellor about what comes up.

Yoga nidra or yoga before bed?

You can do both. A few minutes of gentle bedtime yoga loosens the body, and yoga nidra settles the mind once you are lying down. If your body feels restless, start with movement; if your mind is the busy part, go straight to yoga nidra or progressive muscle relaxation.

With a voice you know

A practice like this is easier with a calm voice to follow. CalmSpace.ai is a calm app for iPhone, Apple Watch and the web with Bliss, a voice companion who remembers you. Its library has guided meditations in Bliss's voice, sleep stories and sleep sounds with a timer that fades, and Breathe together has a 4-7-8 sleep rhythm that Bliss can guide out loud before you settle. She is not a therapist or a medical service. Talking to Bliss by voice is free for up to 10 minutes a day.

Yoga for sleep has a ten-minute routine to do before this, and restorative yoga at home is another way to rest in stillness. The meditation page has more.
