TLDR: Yoga Nidra, also known as Non-Sleep Deep Rest (NSDR), is a relaxation technique that has been shown to positively impact dopamine activity in the brain, improve sleep quality, and reduce stress, anxiety, and depression. Recent scientific studies suggest that NSDR may have significant mental and physical health benefits.
Yoga Nidra, often referred to as Non-Sleep Deep Rest (NSDR) or 'yogic sleep', is an ancient relaxation technique that has gained attention in recent years due to its potential mental and physical health benefits. Scientific research has begun to explore the effects of NSDR on the brain, particularly its impact on dopamine, a neurotransmitter that plays a crucial role in pleasure and motivation.
A study by H. Lou et al., titled "Dopaminergic stimulation enhances confidence and accuracy in seeing rapidly presented words," found that dopaminergic activation can increase confidence and improve performance in a word recognition task. The study also noted that the increased sensory experience in Yoga Nidra meditation is linked to striatal dopamine release, suggesting that NSDR may positively impact dopamine activity in the brain [1].
Furthermore, a comprehensive review by S. Pandi‑Perumal et al., titled "The Origin and Clinical Relevance of Yoga Nidra," discusses recent experimental findings regarding the physiological and psychological effects of NSDR. The review mentions that Yoga Nidra produces changes in endogenous dopamine release, further confirming its potential impact on dopamine [2].
In addition to its effects on dopamine, NSDR has been shown to improve sleep quality. A study by K. Datta et al., titled "Electrophysiological Evidence of Local Sleep During Yoga Nidra Practice," provides electrophysiological evidence of local sleep during Yoga Nidra practice. The study found improvements in sleep duration, efficiency, quality, and total wake duration after just two weeks of practice [3].
NSDR has also been studied for its potential benefits in mental health. A pilot study by Jayshree Kalita and Dr. Purujit Choudhury, titled "A pilot study on effect of yoga-nidra programme on depression, anxiety, and stress among patients with chronic kidney disease receiving haemodialysis," found that Yoga Nidra is a very effective relaxation technique in reducing stress, anxiety, and depression among patients receiving haemodialysis [4].
The growing body of scientific research surrounding Yoga Nidra, or Non-Sleep Deep Rest (NSDR), suggests that this ancient relaxation technique may have significant mental and physical health benefits. By positively impacting dopamine activity in the brain, improving sleep quality, and reducing stress, anxiety, and depression, NSDR has the potential to be a valuable tool in promoting overall well-being. As research continues, we can expect to gain a deeper understanding of the mechanisms behind NSDR's effects and how it can be effectively incorporated into healthcare and personal wellness practices.
