Yoga nidra translates as yogic sleep, and the name is doing it a disservice. It is not sleep and it is not a relaxation recording, it is a structured practice with named stages that have been in the same order for a long time.
What this practice is
The sequence is specific. Settling, then a sankalpa or resolve, then the rotation of consciousness through the body in a fixed order, then breath awareness, then work with pairs of opposite sensations, then imagery, then the resolve again, then return. Each stage does something different and the order is not arbitrary.
The rotation is what people mistake for a body scan, and the difference matters. A body scan invites you to feel each part; the rotation names parts faster than you can deliberately feel them, which keeps the mind moving too quickly to comment. That pace is the mechanism.
The sankalpa is a short positive resolve, stated in the present, kept the same over months, and repeated at the two points in the practice where the mind is least defended. It is not a wish or a goal and the tradition is specific that it should be one sentence and unchanging.
The claim you will encounter is that an hour of yoga nidra equals several hours of sleep. That claim has no good evidence behind it and this app does not make it. What people commonly report is feeling rested out of proportion to the time spent, which is a real observation and a much smaller statement.
When to use it
Use it in the afternoon or early evening, sitting between rest and practice. It is the best available thing for a day that has been long and is not over.
It suits people who find seated meditation difficult, which is a lot of people. Lying down with a voice giving a definite sequence asks much less than sitting with an open instruction.
It also works after physical practice, in the position shavasana would otherwise occupy, if there is time for the full sequence.
The sessions
Yoga Nidra, one practice at three lengths, 10 to 30 minutes. Every session in this collection needs Premium. Four other meditation collections have a free session in them, and the free tier covers twelve guided sessions across the app.
| Length | Tier |
|---|---|
| 10 min | Premium |
| 20 min | Premium |
| 30 min | Premium |
How long to practise for
The shorter sessions compress the sequence rather than shortening the stages, and they are a legitimate way to practise when the long one is not available.
The full-length version is where the rotation and the imagery get the time they were designed around, and it is worth taking occasionally even if the short one is the habit.
The general version of this, and what a longer session actually adds, is in How Long to Meditate For: Choosing a Session Length.
How to use it
Lie on your back, warm, with something under your head. You will not move for the whole session and being cold is the commonest thing that ruins one.
Choose a sankalpa and keep it. Short, present tense, positive, and the same one for months rather than a new one each time.
Follow the rotation at the pace given rather than pausing to feel each part properly. The speed is deliberate and slowing it down turns it into a body scan.
Stay just awake if you can, and do not worry much about it. Sleeping through is common and the tradition treats it as something that settles with practice.
What usually goes wrong
Treating it as a body scan. The rotation moves faster than deliberate feeling, on purpose. Slowing it down to feel each part properly removes the mechanism.
Changing the sankalpa every session. It works by repetition over months. A new resolve each time is a new thought each time.
Believing the sleep equivalence. There is no good evidence for it. Feeling rested out of proportion to the time is real; a substitute for sleep is not.
Practising it cold. Body temperature drops when you lie still for half an hour, and being cold is the most common reason a session is unpleasant.
The full sequence, in order
PanchPrana runs yoga nidra at several lengths, with the longest giving the rotation and the imagery the time the practice was built around. The relaxation sessions are the simpler, shorter neighbour.
Who should take care
Yoga nidra is a deep practice and it is not simply a long relaxation. The cautions reflect that.
If you live with PTSD, complex trauma or a dissociative condition, take care. Deep relaxation with imagery can bring on detachment or surface difficult material, and doing so lying down and alone is the specific risk. Ease off or skip it, and practise with a teacher or therapist who knows your history.
If you live with psychosis, or have a history of it, the imagery stages and the depth of this practice are not appropriate without clinical advice. Skip it. If you have panic disorder, take care with the breath stage and keep to the body.
Stop and open your eyes if you feel detached from yourself or the room, or if distress rises rather than settles, and come back to something ordinary. Do not practise while driving or operating anything. Persistent exhaustion that this does not touch is a matter for a doctor.

Common questions
Is yoga nidra the same as a body scan?
No. The rotation of consciousness inside yoga nidra resembles one, and it moves faster and sits inside a longer sequence with a resolve, breath work, opposites and imagery around it.
Does an hour of yoga nidra really equal four hours of sleep?
There is no good evidence for that and this app does not claim it. What people report is feeling rested out of proportion to the time, which is a much smaller claim.
What is a sankalpa?
A short resolve, stated in the present tense and kept the same over months. It is repeated twice in the practice, at the points where the mind is most receptive.
Is it bad if I fall asleep?
It is common, particularly early on, and the tradition treats staying just awake as something that comes with practice rather than something to force.
Can I use it instead of sleeping?
No. It is rest rather than sleep, and using it to run short on sleep is not what it is for.
