What the review set out to do
Yoga nidra is a guided relaxation practice, usually done lying down, that invites you to rest while following simple instructions. People often use it to wind down at the end of the day. A recent systematic review brought together randomised controlled trials to see what the evidence says about yoga nidra and sleep.
The review, published in the Journal of Integrative and Complementary Medicine, asked a straightforward question: in randomised trials, how does yoga nidra compare with other conditions for sleep outcomes? The authors looked at six trials with a total of 244 participants. They did not combine the results into a meta-analysis, so the findings are described trial by trial rather than as one pooled estimate.
What the trials measured and found
The trials measured sleep onset latency (how long it takes to fall asleep), total sleep time, sleep efficiency and related psychological outcomes. Most of the included trials reported better sleep parameters with yoga nidra than with the comparison condition. In other words, across these small studies, people who practised yoga nidra tended to report or show improvements on those measures compared with the group they were measured against.
That is a promising signal, but it is not a simple answer. The review itself notes important limits.
The limits the review found
Most of the trials had moderate to high risk of bias. That means the way the studies were designed or run could have influenced the results. For example, participants may have known which practice they were doing, or the studies may have been small. Adverse events were poorly reported, so the review could not say much about whether the practice caused any unwanted effects.
Because there was no meta-analysis, we cannot point to a single combined effect size. The review also does not tell us how long the benefits might last, or whether they hold for everyone. The trials varied in how yoga nidra was delivered and what it was compared with, which makes it hard to generalise.
So the honest summary is this: a small set of randomised trials suggests yoga nidra may support better sleep parameters, but the evidence is limited by bias and incomplete reporting. It is not a reason to expect a cure, and it is not a substitute for professional care if sleep problems persist.
How to try it gently
If you are curious, yoga nidra is simple to approach. Lie down or sit comfortably, and let the body be supported. You do not need to force relaxation. The practice is about allowing rest, not achieving a particular state.
You might start with a short guided session in the evening, when you are winding down. Keep the room dim and your expectations light. If your mind wanders, that is part of it. You can gently return to the instructions.
Because the research is still developing, treat it as a way to relax and prepare for sleep rather than a treatment. If you have persistent sleep difficulties or a health concern, it is worth speaking with a professional.
