Yoga Nidra and NSDR: How Non-Sleep Deep Rest Works and How to Try It
What yoga nidra and NSDR (non-sleep deep rest) are, how a session works, what research says about benefits for stress, sleep and focus, a simple 15-minute yoga nidra practice you can try at home and tips for making deep rest a habit.
It's mid-afternoon. You're exhausted, your focus is shot and your to-do list is still long. A nap sounds lovely, but you know it'll leave you groggy, or you just don't have the time. What if there were a way to rest deeply in 10 or 20 minutes, without falling asleep, and come back feeling clearer and calmer?
That's the promise of yoga nidra and its modern cousin, NSDR, short for non-sleep deep rest. These guided relaxation practices have become hugely popular, partly thanks to podcasts and social media, and many people swear by them for stress, sleep and focus. The best part? You do them lying down, doing almost nothing at all.
What is yoga nidra?
Yoga nidra, often translated as "yogic sleep," is a guided meditation practice done lying down. It aims to bring you into a state of deep relaxation while staying aware, somewhere between being awake and being asleep.
Modern yoga nidra was developed and popularized in the 20th century by Swami Satyananda Saraswati, drawing on older yogic and tantric traditions. Today, there are many versions taught around the world, including iRest, a form adapted for therapeutic settings and studied with military veterans.
What is NSDR?
NSDR, or non-sleep deep rest, is a term popularized by Stanford neuroscientist Andrew Huberman to describe practices that bring the body and mind into deep rest without sleep. NSDR often includes yoga nidra-style scripts, along with slow breathing and body scanning, but without the spiritual or traditional language. Think of it as a secular, science-framed version.
How yoga nidra works
A typical session lasts 10 to 45 minutes. You lie down, close your eyes and follow a guide's voice through stages that often include:
- Settling in. Getting comfortable and relaxing.
- Setting an intention (called a sankalpa), a short, positive statement like "I am at peace" or "I am enough."
- Body scan, moving attention through different parts of the body. Our guide to body scan meditation explains this technique.
- Breath awareness, noticing the breath without changing it.
- Opposite sensations, like imagining heaviness and lightness, warmth and coolness.
- Visualization, imagining calming images.
- Returning to the intention.
- Gently coming back to wakefulness.
The aim isn't to fall asleep, though many people do, especially at first. It's to rest deeply while staying gently aware.
What the research says
Research on yoga nidra is growing, though many studies are small.
Stress and anxiety
Several studies have found that yoga nidra practice is associated with reduced stress and anxiety. Studies of iRest, a form of yoga nidra, have explored its use for people with PTSD, including military veterans, with promising early results.
Sleep
Some small studies suggest yoga nidra may improve sleep quality, particularly for people with insomnia, though larger, well-controlled trials are still needed.
Brain and dopamine
A small 2002 brain imaging study found increased dopamine release during yoga nidra meditation. Dopamine is a brain chemical involved in motivation and reward. This finding is often cited in discussions of NSDR, but it was a very small study, so it should be seen as interesting rather than conclusive.
Rest and recovery
Deep relaxation practices in general can activate the body's parasympathetic nervous system, the "rest and digest" system, which can help counter stress. Our guide to the vagus nerve and nervous system regulation explains how this works.
Keep it in perspective
Yoga nidra and NSDR aren't a substitute for real sleep. They can help you rest and recharge, but most adults still need seven to nine hours of sleep per night. Our guide to how much sleep adults need explains why.
Potential benefits
People commonly report:
- Feeling calmer and less stressed
- Falling asleep more easily
- Better quality rest
- Restored energy and focus in the afternoon
- Reduced anxiety
- A greater sense of inner peace
- An easier way into meditation, since it's guided and done lying down
A simple 15-minute yoga nidra practice
You can try this on your own, or record yourself reading it slowly.
1. Settle (2 minutes) Lie on your back on a bed, mat or couch. Place a pillow under your knees if that's comfortable. Cover yourself with a blanket. Let your arms rest by your sides, palms up. Close your eyes.
2. Intention (1 minute) Silently choose a short, positive intention, like "I am calm" or "I am safe." Repeat it three times.
3. Body scan (5 minutes) Slowly bring attention to each part of your body, without moving: right thumb, each finger, palm, wrist, forearm, elbow, upper arm, shoulder. Then the left side. Then your right foot, leg and hip; your left foot, leg and hip. Then your back, belly, chest, neck, face and the top of your head. Simply notice each area.
4. Breath (3 minutes) Notice your natural breathing. Feel your belly rise and fall. Count breaths backward from 27 to 1. If you lose count, start again.
5. Sensations (2 minutes) Imagine your body feeling very heavy, sinking into the bed. Then imagine it feeling very light, almost floating. Then warm. Then cool.
6. Visualization (1 minute) Picture a calming place, like a beach, forest or quiet room. Notice its colors, sounds and smells.
7. Return (1 minute) Repeat your intention three times. Gently wiggle your fingers and toes. Take a deep breath. Roll to one side and slowly sit up.
When to practice
- Afternoon slump: A 10- to 20-minute session can refresh you without grogginess.
- Before bed: To help you wind down and fall asleep.
- After a stressful event: To help your nervous system settle.
- If you wake up at night: To rest even if you can't fall back asleep. Our guide to how to stop overthinking at night has more tips.
Tips for getting the most out of yoga nidra
- Use a guided recording when you're starting. Many free yoga nidra and NSDR recordings are available online.
- Get comfortable and warm. Your body temperature can drop as you relax.
- Don't worry about falling asleep. It's common, especially at first.
- Practice regularly. Even a few sessions a week can help.
- Let go of "doing it right." There's nothing to achieve. Just rest and listen.
Safety notes
Yoga nidra is gentle and safe for most people. However:
- Trauma: For some people, deep relaxation or body awareness can bring up difficult feelings. Keep your eyes open if you prefer, and stop if you feel overwhelmed. Trauma-informed versions are available.
- Mental health conditions: If you have a serious mental health condition, talk to your provider before starting new meditation practices.
- Not a sleep replacement: Use it alongside, not instead of, good sleep habits.
Yoga nidra and spiritual wellness
In its traditional form, yoga nidra is a spiritual practice, a way to explore awareness and inner peace. Many people find that it brings not only rest but a sense of stillness and connection. Whether you approach it as spiritual practice or as science-backed rest, it can be a gentle way to care for yourself. It pairs well with breathwork for beginners and sound baths.
Making deep rest a habit
The easiest way to build a yoga nidra habit is to attach it to something you already do, like right after lunch or as part of your bedtime routine. Keep a favorite recording saved, a blanket nearby and your phone on do-not-disturb. Over time, your body may start to relax as soon as you lie down and press play.
