A plain guide to yoga nidra and NSDR, what the sleep and stress research shows so far, a 10-minute practice script, and where to find free recordings.
What yoga nidra is, and how it differs from NSDR and meditation
Yoga nidra, which translates roughly as "yogic sleep", is a structured relaxation practice from the yoga tradition. You lie on your back, close your eyes and follow a voice through a set sequence: a short intention, a body scan, attention to the breath, paired opposite sensations, and visualisation. The body becomes very still and close to sleep, but you are meant to stay aware of the voice. Drifting off during a session is common and is no cause for concern.
NSDR, or non-sleep deep rest, is the broader term that Andrew Huberman coined for guided rest practices that aim for deep relaxation without full sleep. Yoga nidra is one of them. It adds intention-setting and more yogic language, which the general NSDR term leaves out. Huberman's own NSDR protocols are narrated, last 10 to 30 minutes, and are free on YouTube and major music platforms.
| Feature | Yoga nidra | NSDR (general term) | Seated meditation |
|---|---|---|---|
| Posture | Lying on your back | Lying down or seated, eyes closed | Usually seated, spine upright |
| Who steers attention | A voice, following a set order | A voice, usually body scan and breathing | You, returning attention when it wanders |
| Intention (sankalpa) | Set at the start, repeated at the end | Not part of the standard script | Not part of the standard practice |
| Common length | 10 to 60 minutes | 10 to 30 minutes | Varies widely |
| Research base | A growing number of small trials, many from India | A handful of small trials | A large, mixed body of trials |
In practice the difference is small. A 10-minute NSDR track and a 10-minute yoga nidra recording share most of their steps. Choose the one whose voice and language you can relax with. Some people find yogic language grounding, and others find it off-putting.
What the research shows for sleep
Sleep is the claim most readers care about, and it is where the evidence is thinnest. A 2026 systematic review and meta-analysis in Sleep and Breathing pooled studies of yoga nidra in adults with poor sleep or insomnia.1 Only two randomised trials measured sleep quality with the Pittsburgh Sleep Quality Index. Their pooled effect was substantial, but it did not reach statistical significance. Two trials that measured insomnia severity also showed no significant effect. The authors rated the certainty of the evidence as very low, called the findings preliminary, and noted that the trials were concentrated in India.
A 2021 trial in chronic insomnia
A 2021 randomised trial from India, published in the National Medical Journal of India, is the most relevant study here.2 It compared yoga nidra with cognitive behavioural therapy for insomnia (CBT-I), the standard recommended treatment for chronic insomnia, in 41 adults. Both groups reported better sleep diary measures, including total sleep time, sleep efficiency and time awake after falling asleep. Both groups also improved on overnight sleep recordings, so the change was visible beyond what people reported. Salivary cortisol, a stress marker, fell significantly after yoga nidra. With 41 participants, the trial cannot show how large or how lasting the effect is.
A 2023 sleep-lab study
A 2023 randomised study in the Journal of Psychosomatic Research tested yoga nidra in 22 adults with self-reported insomnia. Its main purpose was to check whether a full trial was practical.3 Participants tolerated the practice well and found it believable. Compared with lying quietly, it did not change how long people took to fall asleep, and it showed no between-group change in the main brain-activity measure. The one clear difference was a slower breathing rate during and after the session, which the authors said needs confirmation.
Taken together, the sleep findings are promising but thin. Participants in these trials tolerated yoga nidra well, but safety reporting is limited, and it has not been shown to improve sleep for most people.
Mindfulness meditation has a stronger sleep record. A 2019 meta-analysis of 18 randomised trials, covering 1,654 people, found moderate-strength evidence that mindfulness meditation improved sleep quality compared with time- or attention-matched control groups. Compared with established sleep treatments, the difference was not clear, and that evidence was of low strength.4 Yoga nidra has been compared with CBT-I in only one small trial, described above, so its evidence base is narrower than the meditation literature.

What the research shows for stress and mood
The stress evidence is broader than the sleep evidence, but its pooled numbers are easy to overstate. A 2025 systematic review and meta-analysis in Annals of the New York Academy of Sciences pooled 73 studies with 5,201 participants.5 Pooled effects on stress, anxiety and depression were moderate to large, both against active comparators and against no comparator. The authors warned that most studies were of low methodological quality, and that the pooled estimates are likely overstated. The result justifies a trial of the practice, not a verdict on it.
The most specific NSDR evidence comes from a 2024 randomised trial in 65 physically active adults. Half did a 10-minute NSDR session, and half sat passively for 10 minutes.6 The NSDR group reported better scores on questionnaires about stress, emotional balance, recovery and negative mood. Their handgrip strength and reaction times also changed more than the sitting group's. These are short-term effects in active adults, and they do not establish any effect on night-time sleep.

A 10-minute yoga nidra script
This script follows the classic order: settle, intention, body scan, breath, opposites, imagery, intention again, and return. Read it through once before you start, or record yourself reading it slowly, with pauses. The pauses matter more than the words. Keep your voice low and unhurried.
- 0:00 to 1:00, settle. Lie on your back with a small pillow under your head and a blanket over you. Put a cushion under your knees if your lower back is sensitive. Turn your phone to do-not-disturb. Let your arms rest beside you, palms up. Take three slow breaths, with the out-breath a little longer than the in-breath.
- 1:00 to 1:30, intention. Choose one short sentence in the present tense, such as "My body is safe and I can rest." Say it silently once. Do not try to force a feeling.
- 1:30 to 4:00, body scan. Bring your attention to the right big toe and name it silently. Move slowly through the right foot, ankle, calf, knee, thigh and hip, spending a few seconds on each part. Repeat on the left side. Then move through the belly, chest, shoulders, upper arms, forearms, hands, neck, face and the top of the head. Notice each area without trying to change it.
- 4:00 to 5:30, breath. Notice the breath at the nostrils: cooler air coming in, slightly warmer air going out. Then move your attention to the belly, rising and falling. Let the breath stay natural, and watch it rather than control it.
- 5:30 to 7:00, opposites. Quietly notice pairs of sensations: heavy and light, warm and cool, tense and soft. Let each one arise and pass without judging it.
- 7:00 to 8:30, imagery. Picture a calm place you know, such as a lake at dusk or a quiet room. Notice the colours first, then any sounds, then the air on your skin. If the image fades, return to the breath.
- 8:30 to 9:15, intention again. Repeat your sentence three times, slowly, as if settling it into the body.
- 9:15 to 10:00, return. Let your awareness widen to the room. Move your fingers and toes. Roll onto your right side and rest for a breath or two, then sit up slowly. If you fell asleep during the script, that is fine. Begin the next session the same way.
When to practise: bedtime, night waking or the afternoon
At bedtime
Practise in bed, after the lights are down. If you worry about the recording ending before you fall asleep, choose a 30 to 60 minute track. Huberman recommends longer versions for this purpose. Falling asleep during the practice is expected, and a familiar recording often settles people faster than a new one each night.
Some people pair the routine with an evening supplement. A serve of Deep Rest, which contains magnesium bisglycinate, is labelled for one serve 30 to 60 minutes before bed. The two are separate choices, and the practice does not depend on the supplement.
When you wake in the night
A short recording can help when you wake and lie there awake. Avoid checking the clock or your phone, because checking can keep you alert. If you still cannot fall back asleep after a while, get up, sit somewhere dim and calm, and return to bed when you feel sleepy. That stimulus-control step is one of the core techniques of CBT-I.
In the afternoon, in place of a nap
The evidence does not show that yoga nidra replaces a nap or the sleep a nap provides. It can, however, work as a low-effort reset when you would otherwise doze off in a chair. A 10 to 20 minute practice, lying down or in a reclined chair, in the early afternoon is a reasonable option during the usual dip. If your evening sleep is poor, finish earlier in the afternoon so that the practice does not run into the night. If you do nap, keep it under about 25 minutes to avoid grogginess on waking.
Free recordings worth trying
You do not need to pay for a recording to start. These free options are worth a first listen:
- Yoga Nidra Network library. More than 600 recordings in 23 languages, streamable free of charge, from teachers around the world. Use the style filter to find the Satyananda style, a structured method developed by Swami Satyananda Saraswati, founder of the Bihar School of Yoga in Munger, India.
- Jeffrey Balinsky's Nidra archive. Free live recordings, several around 15 to 35 minutes, some made at the end of yoga classes. The site invites you to play, download and share them.
- Tanis Fishman's free recordings. A library of practices recorded over more than twenty years of practice and teaching, arranged chronologically, so you can start with the older recordings or go to the newest ones.
- Andrew Huberman's NSDR protocols. Narrated 10, 20 and 30 minute NSDR sessions, free on YouTube and major music platforms. The 10-minute version is the closest match to the script above in length.
When you choose a recording, check three things: a voice you find easy to follow, a length that fits your use, and few or no ads, since ads interrupt the rest you are trying to reach. In-person classes are worth the cost if you want feedback on posture and technique, and a teacher can adapt the practice if lying flat is uncomfortable for you.
Where Deep Rest fits
Deep Rest is a magnesium bisglycinate supplement from The Stack. Each serve provides 92.2 mg of elemental magnesium from magnesium bisglycinate. The label suggests one serve daily, 30 to 60 minutes before bedtime, and the product is positioned to support evening wind-down and muscle relaxation. Start with one serve and follow the label. Do not exceed the stated serving.
Deep Rest is optional, and the practice does not need it. If you take medicines, ask a doctor or pharmacist before you start a magnesium supplement, because magnesium can interact with some medicines.
Frequently Asked Questions
Is yoga nidra the same as NSDR?
Not exactly. NSDR is the broader term for guided rest practices, and yoga nidra is one of them. Yoga nidra adds an intention and more yogic language.
Can yoga nidra replace sleep?
No. It is a relaxation practice, and it does not replace a night of sleep. Keep a steady sleep schedule alongside it.
How quickly might I notice a difference?
A single session can leave some people calmer. Short-term calm is one thing, and better sleep over weeks is another. The sleep trials were small, so the size of any lasting effect is uncertain.
Is yoga nidra safe?
Participants in the trials tolerated it well, but safety reporting in the research is limited. Check with a clinician first if you are pregnant, have had recent surgery, have a mental health condition, have a history of trauma, or take medicines. Stop if the practice feels distressing.
Do I need a teacher?
No. Recordings are a good start. A teacher can correct posture and timing, so an in-person class is worth considering once you know you want to continue.
Can I use yoga nidra and Deep Rest together?
Yes, they are independent choices. Follow the Deep Rest label, and speak with a doctor or pharmacist first if you take any medicines.
When should I see a doctor about sleep?
See a doctor if poor sleep lasts most nights for several weeks, if you snore loudly with pauses or gasping, or if daytime sleepiness affects your work or your driving.
