What yoga nidra is
Yoga nidra is a guided relaxation practice. You lie down, usually on your back, and follow a voice through a sequence of simple instructions: sensing the body, noticing the breath, and letting attention rest. It is sometimes called non sleep deep rest, or NSDR. The aim is not to fall asleep. The aim is to relax and rest while staying gently awake.
A 2021 randomised controlled trial by Datta and colleagues, published in the National Medical Journal of India, looked at what happened when people with chronic insomnia practised yoga nidra. The study is a useful place to start because it describes both how the practice was taught and what changed over the trial.
What the study did
The trial recruited people with chronic insomnia and randomly assigned them to a yoga nidra group or a control group. Randomisation matters: it means the groups were formed by chance rather than by choice, which helps reduce bias.
The yoga nidra group practised regularly over the course of the trial. The paper describes the protocol and the way sessions were delivered, so the practice was structured rather than left open. The control group did not receive the same practice during the trial period.
The main measure was sleep, assessed with standard questionnaires and sleep measures used in the study. The researchers compared what changed in each group.
What the study found
The yoga nidra group showed improvement on the sleep measures used in the trial, and the paper reports that the changes were statistically significant compared with the control group. In plain terms, people who practised yoga nidra reported better sleep than those who did not, across the period studied.
The study also reported changes on other measures it collected. The findings are encouraging for anyone who wants a gentle, low effort way to wind down before bed.
It is worth being precise about what this means. The trial tested a structured yoga nidra programme in a particular group of people over a particular period. It did not test whether yoga nidra replaces other care, and it did not follow people for years. The results describe what happened in this trial, not a promise about what will happen for every person.
The limits
Every study has limits, and this one is no exception.
First, the sample was a specific group: people with chronic insomnia who agreed to take part in a trial. People who volunteer for a sleep study may differ from the wider population.
Second, the trial ran for a defined period. We do not know from this paper whether the improvements lasted after the practice stopped, or whether they grew with longer practice.
Third, yoga nidra is a guided practice, and the experience depends on the guidance, the setting and the person. A trial standardises these things; daily life does not.
Fourth, sleep is measured partly through self report. Questionnaires capture how people feel about their sleep, which is valuable, but it is not the same as a laboratory measure.
None of this undoes the finding. It simply places it: a randomised trial found improvement in sleep with a structured yoga nidra practice, and more research would help show how general the effect is.
If sleep problems persist, or if they are affecting your days, it is worth speaking with a health professional. This article is general information, not medical advice.
How to try it gently
Yoga nidra is simple to approach. Lie down somewhere warm and quiet. Let the body be supported. Follow a guided practice and let the instructions do the work. There is nothing to achieve and nothing to force. If the mind wanders, that is part of it. If you feel sleepy, that is fine too.
A short practice is enough to begin. Many people find a guided session helpful as part of winding down in the evening, before sleep. The key is regularity rather than intensity.
Try it
If you would like to rest in this way, our guided practice Yoga Nidra for Sleep is a gentle place to start. Lie down, settle, and let the guidance carry you through.
