Yoga Nidra: The 8 Stages, a 20-Minute Script and What the Research Really Shows

Most people come to Yoga Nidra tired. Tired from work, from screens, from a mind that will not switch off at night.

Then they lie down, a voice starts talking, and 30 minutes later they sit up feeling clear and calm. Many say, "I don't know where I went, but I feel better."

This guide explains what really happens in those 30 minutes. You get the 8 stages, a short script you can use tonight, an honest look at the research, and how we teach Yoga Nidra to future teachers here in Rishikesh.

Written by Mayuri Shewale, E-RYT 500 (Yoga Alliance) and founder of Swaastik Yog School in Rishikesh, with Swami Anand, who leads the meditation and Yoga Nidra sessions on our teacher trainings. The research below was checked against the published studies in October 2026. This article is general education, not medical advice.

What is Yoga Nidra, in plain words?

Yoga Nidra is a guided practice that takes you to the edge of sleep while part of you stays aware. You lie on your back in Savasana (corpse pose). A teacher, or a recording, guides your attention step by step.

The modern form was shaped by Swami Satyananda Saraswati of the Bihar School of Yoga. He published his book Yoga Nidra in 1976. He drew on older tantric practices, such as nyasa, where attention is placed on different parts of the body.

The idea is simple. Your body rests deeply. Your mind follows a voice. You do not try to empty your mind or hold a focus. You just follow along.

How is Yoga Nidra different from meditation, a nap, or Savasana?

Yoga Nidra is a type of guided meditation, but it feels very different from sitting meditation. The main difference is effort. Seated meditation asks you to hold your attention. Yoga Nidra asks you to let go and follow.

	Yoga Nidra	Seated meditation	Savasana	A nap
Position	Lying down	Sitting upright	Lying down	Lying down
Guided?	Yes, from start to end	Sometimes	Usually silent or a few cues	No
Effort	Very low: just listen	Medium: you hold your focus	Low	None
Awareness	Aim to stay softly aware	Fully awake	Awake, resting	Asleep
Usual length	20–45 minutes	5–60 minutes	5–10 minutes	Any
Structure	Fixed stages	One technique	Open	None

Some people now use the term NSDR ("non-sleep deep rest") for similar practices. The idea overlaps a lot with Yoga Nidra, but without the yogic parts such as the sankalpa.

What are the 8 stages of Yoga Nidra?

A classic Yoga Nidra session follows 8 stages in a fixed order. Each stage relaxes you a little more. Teachers count the stages a little differently (some say 7, some say 8), but the order is the same. Here is how a 30-minute session is usually timed.

Stage	What you do	Why it helps	Time (30-min session)
1. Settling	Lie still. Notice sounds, the floor, your clothes.	Moves you from "doing" to "resting".	3 min
2. Sankalpa	Silently say a short, positive intention 3 times.	Gives the practice a purpose.	1–2 min
3. Body rotation	Move your attention quickly through named body parts, without moving.	Keeps the busy mind gently occupied so the body can let go.	8–10 min
4. Breath awareness	Watch the natural breath, or count breaths backwards.	Slows you down and deepens rest.	4–5 min
5. Opposites	Feel heavy, then light. Warm, then cool.	Trains you to feel things without reacting.	3 min
6. Images	Picture simple things the guide names: a candle, a river, the sky.	Calms the thinking mind with pictures instead of words.	4–5 min
7. Sankalpa again	Repeat your intention 3 times.	Closes the practice with your purpose.	1 min
8. Return	Notice the room. Move fingers and toes. Roll to the side. Sit up slowly.	Brings you back without feeling groggy.	2–3 min

What is a sankalpa, and how do I pick one?

A sankalpa is a short, positive sentence you choose before you start. You say it in the present tense, as if it is already true. Keep it to one line.

• "I am calm and steady."
• "I sleep deeply and wake up rested."
• "I am kind to myself."

Our tip: pick one sankalpa and keep it for a few weeks. Changing it every day makes it feel like a to-do list.

A short Yoga Nidra script you can use tonight (about 20 minutes)

This is a simple outline. Read it slowly into your phone and play it back, or ask a friend to read it to you. Pause where you see "(pause)". Speak in a soft, even voice. Do not rush.

1. Settling (2 minutes)

"Lie on your back. Let your feet fall open. Rest your arms a little away from your body, palms up. Close your eyes. (pause) Notice the sounds far away. (pause) Now the sounds close to you. (pause) Feel your body on the floor. You do not need to do anything. Just listen to my voice and stay aware. Say to yourself: I am awake. I am practising Yoga Nidra."

2. Sankalpa (1 minute)

"Now remember your sankalpa. Say it silently three times, with feeling. (pause)"

3. Body rotation (6 minutes)

"Take your attention to the right hand thumb. Second finger. Third finger. Fourth finger. Little finger. Palm. Back of the hand. Wrist. Elbow. Shoulder. Right side of the waist. Hip. Knee. Ankle. Heel. Sole of the foot. Big toe... second toe... third... fourth... little toe."

Repeat on the left side. Then the back of the body: heels, calves, back of the knees, buttocks, spine, shoulder blades, back of the head. Then the front: forehead, eyebrows, eyes, nose, cheeks, lips, chin, throat, chest, belly. End with: "Whole right leg. Whole left leg. Both arms. Whole body. Whole body together."

4. Breath (4 minutes)

"Notice your natural breath. Do not change it. (pause) Now count the breaths backwards, from 27 down to 1. Breathing in, 27. Breathing out, 27. Breathing in, 26. Breathing out, 26... If you lose count, start again at 27. It does not matter."

5. Opposites (2 minutes)

"Feel your body becoming heavy. So heavy it sinks into the floor. (pause) Now feel it becoming light. Light, as if it could float. (pause) Feel warmth, like sitting in the sun. (pause) Now feel cool, like a breeze by the river. (pause)"

6. Images (3 minutes)

Name each image, then pause for 3–5 seconds: "A candle flame. (pause) A full moon. (pause) A river at sunrise. (pause) A mountain covered in snow. (pause) A temple bell. (pause) A clear blue sky. (pause) Your own body, lying peacefully here."

7–8. Sankalpa and return (2 minutes)

"Now repeat your sankalpa three times. (pause) Become aware of your breath. The floor under you. The sounds in the room. Slowly move your fingers and toes. Stretch if you like. Roll onto your right side. When you are ready, sit up slowly. Yoga Nidra is now complete."

What does the research say about Yoga Nidra benefits?

The research is encouraging, but it is still early. Many studies are small, short, or not well controlled. So we use careful words here: "may help", not "cures".

Benefit	What the research found	How strong is it?
Stress	A 2025 review of 73 studies (5,201 people) found Yoga Nidra was linked to lower stress.	Promising. The authors warn the studies were often weak, so real effects may be smaller.
Anxiety	The same review found lower anxiety scores.	Promising, same warning.
Low mood	The same review found lower depression scores.	Promising, same warning. Not a replacement for treatment.
Sleep	An online study of an 11-minute Yoga Nidra found better sleep quality after 30 days, compared with a waitlist group.	Real but very small to small effects.
Brain chemistry	A 2002 brain-scan study of 8 yoga teachers found more dopamine activity during Yoga Nidra than during a quiet listening task.	Interesting, but tiny and very early.

Stress, anxiety and low mood

The biggest summary so far was published in the Annals of the New York Academy of Sciences (Ghai and colleagues, online December 2025). It pooled 73 studies with 5,201 people. Yoga Nidra was linked to lower stress, anxiety and depression scores.

The authors were honest about the limits. Many studies were low quality, and Yoga Nidra was taught in many different ways. They said the effects are probably smaller than they look, and better trials are needed.

Sleep

A German team (Moszeik, von Oertzen and Renner, Current Psychology) tested an 11-minute Yoga Nidra recording used for 30 days. The practice group (341 people) reported less stress, better well-being and better sleep quality than a waitlist group (430 people). The effects were very small to small.

So a short daily practice can help a little. It is a gentle tool, not a sleeping pill.

You may have heard that "30 minutes of Yoga Nidra equals 2 to 4 hours of sleep." It is a popular saying, but we could not find good research to support it. Yoga Nidra is deep rest. It does not replace sleep.

The brain

In 2002, Danish researchers (Kjaer and colleagues) scanned the brains of 8 experienced yoga teachers twice: once during Yoga Nidra, and once while they listened to speech with their eyes closed. During Yoga Nidra they saw signs of more dopamine release in a part of the brain linked to reward. It is an interesting early result, but 8 people is a very small group.

Trauma and PTSD

A version of Yoga Nidra called iRest was developed by psychologist Richard Miller and has been used with US military veterans. Early results were positive, but the evidence is still limited. If you live with trauma, practise with a trained professional, not alone with a recording.

Is Yoga Nidra safe for everyone?

For most people, yes. You are lying down and resting. But a few people should take care.

• Trauma or PTSD: body-focused practices can bring up strong feelings. Work with a therapist who knows these methods.
• Serious mental health conditions: talk to your doctor or therapist before you start.
• Back pain or pregnancy: put a bolster under your knees, or lie on your left side with a pillow between your knees.
• Strong emotions: tears or old memories can come up. That is common. You can open your eyes and stop at any time.

How do I practise Yoga Nidra at home?

You need a quiet space, a blanket and 20–30 minutes. That is it.

1. Pick a time. Before bed if you want to sleep. Early afternoon if you want energy without a groggy nap.
2. Get warm. You may feel cooler as you relax. Use a blanket and socks.
3. Support your body. A thin pillow under your head. A rolled blanket under your knees.
4. Cover your eyes. An eye pillow or a scarf helps.
5. Silence your phone. Use airplane mode if you play a recording.
6. Use a guide. Beginners do best with a voice to follow. Start with 15–20 minutes, then try 30.
7. Be regular. A short daily practice is better than one long session a week. The sleep study above used daily practice for 30 days.

What if I fall asleep?

It happens to almost everyone at first. Do not worry. You still rested. Over time, most people learn to stay on the soft edge between awake and asleep. If you keep falling asleep, practise earlier in the day, or rest your forearm upright on the elbow. When you drift off, it falls and wakes you gently.

How is Yoga Nidra taught at our school in Rishikesh?

At Swaastik Yog School, Yoga Nidra is led by Swami Anand. He has over 20 years of meditation practice and teaching. He leads the meditation, Yoga Nidra and Vedanta sessions on our teacher trainings.

Here is where Yoga Nidra appears in each of our programmes, based on our published course syllabi:

Programme	Where Yoga Nidra fits	Length	Price (from)
200-hour TTC	"Meditation & Yoga Nidra" module, alongside trataka, mantra and body-scan meditation. You also practise guiding short meditations yourself.	22 days, 15–20 students	$440 (dorm) / $880 (shared) / $1,100 (private)
300-hour TTC	A daily evening "Meditation / Yoga Nidra" session (6–7 pm) in the timetable.	22 days	$660 (dorm)
500-hour TTC	"Trataka and Yoga Nidra" in the meditation module.	51 days	$880 (dorm)
Online TTC	"Yoga Nidra (yogic sleep)" and "Teaching meditation to beginners" in the meditation module.	Live on Zoom, max 4 students	$440

Our residential TTC prices include your course, your room, 2 sattvic meals a day and taxes. You reserve a seat with a 10% deposit and pay the rest on arrival.

Is there a "Yoga Nidra teacher training" at Swaastik?

We want to be clear: we do not run a separate, stand-alone Yoga Nidra certificate. Yoga Nidra is taught inside our Yoga Alliance teacher trainings, as part of the meditation module.

For most new teachers, this is the better route. Yoga Nidra works best when you also understand the body, the breath and how to hold a room. In a 200-hour course you learn all of these together. You experience Yoga Nidra as a student first, again and again, before you guide others.

If you already teach yoga and only want a deep Yoga Nidra specialisation, a dedicated Yoga Nidra programme may suit you better. Look for one with lots of supervised practice teaching, not just recordings.

What makes a good Yoga Nidra teacher?

• Your own practice. You cannot guide a place you have never been. Practise daily for months before teaching.
• A steady, slow voice. Most new teachers speak far too fast. Leave long pauses.
• A clear structure. Keep to the 8 stages so students feel safe.
• Simple words. "Right hand thumb" works better than poetry.
• Care for students. Know who should be careful, and always let people open their eyes or stop.
• No big promises. Say "this may help you rest", never "this will cure your insomnia".

Frequently asked questions

How long should a Yoga Nidra session be?

Most sessions last 20 to 45 minutes. A full classic session with all 8 stages is usually about 30 minutes. If you are new, start with 15 to 20 minutes. Even an 11-minute daily practice showed small benefits in one large online study.

Can I do Yoga Nidra in bed?

Yes. Doing it in bed is fine if your goal is to fall asleep. If you want to stay aware through the whole practice, lie on a mat on the floor instead. The bed tells your body it is time to sleep.

Can I write my own Yoga Nidra script?

Yes. Keep the 8 stages in the same order: settling, sankalpa, body rotation, breath, opposites, images, sankalpa again, and return. Use short, simple words and leave long pauses. The 20-minute script above is a good starting point.

How often should I practise Yoga Nidra?

Once a day is a good goal. Short and regular works better than long and rare. Try it daily for a month, then notice how you feel.

Is Yoga Nidra the same as hypnosis?

No. In Yoga Nidra you are asked to stay aware, and you choose your own intention (sankalpa). Nobody gives you suggestions to change your behaviour. You can open your eyes and stop at any time.

Can Yoga Nidra replace sleep?

No. Yoga Nidra gives you deep rest, but it does not replace a full night's sleep. The popular idea that "30 minutes equals hours of sleep" is not backed by good research.

Do I learn to teach Yoga Nidra in a 200-hour course?

At Swaastik Yog School, yes, as part of the meditation module. Our 200-hour course includes a "Meditation & Yoga Nidra" module led by Swami Anand. You practise Yoga Nidra regularly and practise guiding short meditations yourself. We do not offer a separate Yoga Nidra-only certificate.

Can beginners do Yoga Nidra?

Yes. It is one of the easiest practices to start. You do not need to be flexible or fit. You just lie down and listen. People with trauma or serious mental health conditions should check with a professional first.
