Yoga nidra
Yoga nidra is a guided practice of deep rest, done lying down. A voice leads your attention through a set of steps. There’s an intention, then the body part by part, the breath, a few contrasting feelings and some simple images. Your body rests as it would before sleep. The aim is to stay aware while it does.
The name is often translated as yogic sleep. That can mislead. It isn’t sleep, and it isn’t a nap. If you fall asleep, that’s all right. But the practice itself is resting awake.
Where it comes from
The words are much older than the practice. In the Mahābhārata, yoga nidra is the god Vishnu’s sleep between the ages of the world. In medieval yoga texts, it names a deep state of meditation, beyond waking, dreaming and sleep.
The guided practice most recordings follow today is modern. Swami Satyananda Saraswati set it out at the Bihar School of Yoga, in his book Yoga Nidra, first published in 1976. He said he built it from little-known practices in tantric texts. The scholars Jason Birch and Jacqueline Hargreaves point out that some of it is new. The intention, for example, seems to draw on Western relaxation methods. Other teachers have made their own versions since. Richard Miller’s iRest is one well-known example.
NSDR, short for non-sleep deep rest, is a newer name. The neuroscientist Andrew Huberman coined it for yoga nidra without its spiritual language. It’s now used for a wider group of deep-rest practices too.
The steps of a typical practice
Satyananda’s version has seven parts. Many recordings follow them, often in a shorter form:
- Settling. You lie down, get comfortable, and decide to stay awake. You notice sounds, near and far.
- An intention. You choose a short, positive sentence, such as “I am at ease”, and say it to yourself three times. In Sanskrit it’s called a sankalpa.
- The body, part by part. The voice names parts of your body quickly, one after another. Right hand thumb. Second finger. Third finger. Your attention goes to each part as it’s named.
- The breath. You feel your breathing, and often count breaths backwards.
- Opposites. You feel heaviness, then lightness. Warmth, then coolness.
- Images. The voice names a few simple pictures, one after another. You let each one appear, or not.
- Coming back. You say your intention again. Then you feel your body and the room, move slowly, and open your eyes.
The tour of the body is the heart of it. It moves faster than a body scan. You don’t stay with each part. You touch it with your attention and move on. Body scan meditation explains the slower way.
Yoga nidra, NSDR and sleep meditation
They overlap, but their aims differ.
| Yoga nidra | NSDR | Sleep meditation | |
|---|---|---|---|
| What it is | A set sequence from yoga | A name for several deep-rest practices | A practice to help you settle for the night |
| Awake or asleep | Resting awake | Usually resting awake, often in the day | Falling asleep is welcome |
| How it ends | It brings you back to the room | It often brings you back | It often doesn’t, so you can sleep |
If you want help falling asleep, Sleep meditation is the better guide.
How to practise at home
Lie on your back on a bed, a mat or a rug, with your arms a little away from your sides. A pillow under your knees eases your lower back. Keep a blanket over you, since lying still for a while can leave you cool.
Most practices take 20 to 40 minutes. Choose a time when no one will need you. The day is a good time if you want to stay awake. At bedtime, sleep may come, and that’s fine too.
If lying on your back is hard, lie on your side or recline in a chair. Being comfortable matters more than the position.
Choosing your intention. Keep it short, and say it as if it’s already true: “I am at ease.” “I’m patient with myself.” Choose one you can keep for a while, rather than a new one each time. It’s a direction to lean in, not a demand.
If it doesn’t go as you expect
You fall asleep. That’s common, especially when you’re tired. You’ve still rested. Try it earlier in the day, or a little less snug, with a thinner pillow.
You can’t keep up. The names come quickly. Let the ones you miss go. When you catch up, join the part being named. There’s no need to go back.
An image is unwelcome. Let it go, and come back to the voice or your breath. You can open your eyes at any time.
You feel restless or uneasy. Deep stillness doesn’t suit everyone, every time. Attention on the body, or an image, can bring up a memory. You can keep your eyes open, move, or stop. If you’ve been through trauma, a teacher trained to work with it can help you adapt the practice.
You feel groggy after. Sit up slowly, and give yourself a minute before you stand, or before you drive.
What the research says
There are many studies of yoga nidra. Most are small, and many had no comparison group. A 2025 review gathered 73 studies with about 5,200 people. On average, people reported less stress, anxiety and low mood after practising. But only 22 of the studies were randomised trials, and none of those had a low risk of bias. The authors said the results should be read with considerable caution. They see yoga nidra as a possible addition to treatment, not a replacement for it.
One randomised trial followed 362 adults for two months. Some practised with a recording, ideally every day. Those using an 11-minute recording reported a little less stress, anxiety and low mood than people on a waiting list. Against ten minutes of music, it helped only with low mood. A 30-minute version did a little better. All the effects were small.
You may read that a short session can stand in for hours of sleep. There’s no good evidence for that. Rest is worth having, but it doesn’t replace sleep.
In these meditations
- Resting Awake is a complete yoga nidra of about 19 minutes, lying down. It follows Satyananda’s steps, and adds a place of ease to come back to, from iRest. Slow ocean waves sit far off under the voice.
These offer some of the same rest:
- Here, in Your Body moves attention through the body, from your feet to the top of your head, and brings you back to your day.
- Being, Awareness, Joy rests in awareness itself, with long quiet spaces and a guided return.
- Night Weight is for sleep, with no waking at the end.
