Yoga Nidra for Sleep: What It Is, How It Works and a Simple Practice
In a 2002 PET study, Troels Kjaer and colleagues in Copenhagen measured brain chemistry during yoga nidra and found a rise in dopamine release in the striatum compared with ordinary rest, one of the first imaging studies of a meditation state.
Yoga nidra, Sanskrit for "yogic sleep", is one of the easiest practices to try if your mind will not switch off at night. You lie down, close your eyes and follow a voice that moves your attention through the body, the breath and a few simple images. There is nothing to get right and no posture to hold.
This guide explains where yoga nidra comes from, what happens in a session, what research says about sleep and stress, and how to do a short version tonight. If racing thoughts are the main problem, see also our guide to sleep meditation for a racing mind.

Quick Answer
Yoga nidra ("yogic sleep") is a guided practice done lying down in which a voice leads you through a body scan, breath awareness and imagery to a state between waking and sleep. It was shaped into its modern form by Swami Satyananda Saraswati in the 1960s. Studies suggest it can reduce stress and help some people fall asleep, and a session at bedtime often ends in sleep.
What Is Yoga Nidra?
Yoga nidra is a guided, lying-down practice that aims for a state of deep relaxation while some awareness remains. Teachers describe it as hovering at the edge of sleep: the body heavy and still, the mind quiet but listening.
The idea of yogic sleep appears in older Indian texts, but the structured practice taught today was developed by Swami Satyananda Saraswati of the Bihar School of Yoga in the 1960s, drawing on tantric practices such as nyasa, placing attention on parts of the body. His book Yoga Nidra (1976) set out the stages most teachers still use. Later versions include Richard Miller's iRest, which has been used in programmes for veterans in the United States.
The Stages of a Yoga Nidra Session
A Typical Session
1. Settle
Lie on your back, arms by your sides, and notice the sounds around you.
2. Sankalpa
Repeat a short, positive intention three times, such as "I rest easily".
3. Body rotation
Attention moves quickly from point to point: right thumb, index finger, wrist and so on.
4. Breath
Counting breaths backwards, or feeling the breath in the belly and nostrils.
5. Opposites
Feeling heavy then light, warm then cool, to loosen the hold of thinking.
6. Imagery
A series of quick images or one calm scene.
7. Sankalpa again
The same intention, repeated.
8. Return or sleep
Daytime sessions end with movement; bedtime sessions can simply fade.
The body rotation is the heart of the practice. Moving attention quickly from one point to the next is easy to follow and leaves little room for worry, which is part of why people often fall asleep during it.
Does Yoga Nidra Help You Sleep?
The research is promising, though still modest in size. A 2022 study by Karen Moszeik, Timo von Oertzen and Karl-Heinz Renner in Current Psychology gave hundreds of participants a short daily yoga nidra recording for 30 days and found improvements in stress, sleep quality and well-being compared with a waiting-list group.
Smaller clinical studies have tested yoga nidra as an add-on for chronic insomnia, with encouraging results. It is not a replacement for medical care: if you have long-term insomnia, cognitive behavioral therapy for insomnia (CBT-I) remains the recommended first treatment, and yoga nidra can sit alongside it.
The likely reasons it helps are familiar from other sleep techniques: a guided task that occupies attention, slower breathing and a calmer body. Narrated bedtime stories for adults work on a similar principle, giving the mind something gentle to follow.
A word on dopamine
Kjaer's 2002 PET study found higher dopamine release during yoga nidra. It was a small study of eight experienced practitioners, so treat it as an interesting signal rather than proof of a mechanism.
Yoga Nidra and NSDR: What's the Difference?
NSDR, short for non-sleep deep rest, is a term popularised by Stanford neuroscientist Andrew Huberman for practices that bring deep rest without sleep, including yoga nidra and some hypnosis scripts. Most NSDR recordings are a stripped-down yoga nidra: body scan and breath, without the Sanskrit terms or the intention.
If you want rest in the afternoon, NSDR or a short yoga nidra with a waking ending works well. At bedtime, choose a version with no wake-up instruction, so you can drift straight into sleep.
A Simple 15-Minute Yoga Nidra for Bedtime
Read this through once, then follow it from memory or record it slowly on your phone.
Lie on your back and let your arms rest by your sides. Notice the sounds far away, then the sounds close by. Feel the bed under you. Silently say your intention three times: I rest easily. Now bring your attention to your right hand. The thumb. The index finger. The middle finger. The ring finger. The little finger. The palm. The back of the hand. The wrist. The elbow. The shoulder. The right side of the chest. The right hip. The knee. The ankle. The heel. The toes. Now the left hand, and move the same way down the left side. The whole back of the body, resting on the bed. The whole front of the body. The whole body, together. Now feel the breath at the belly. Count each out-breath backwards from 27: 27, 26, 25. If you lose count, start again at 27. Feel the body heavy, sinking. Then light, floating. Picture a lamp being turned down, a quiet harbour at night, a single star. Repeat your intention once more. There is nothing more to do.
Make it easier
Keep the room cool and dark, use a pillow under the knees if your back is stiff and set a sleep timer if you play a recording. Falling asleep before the end is a good result at bedtime.
Who Should Try Yoga Nidra?
Yoga nidra suits people who find sitting meditation hard, people who lie awake with busy minds and anyone who wants a structured way to rest during the day. Because you lie still, it is accessible for most bodies.
If imagery-based practices appeal to you, our free guided imagery scripts and narrated story journeys offer the same kind of guided rest with more scenery and less body focus.
