Scientific studies have investigated the effects of the Yoga Nidra practice on numerous neurological, neurocognitive, and psychological disorders, as well as its systemic physical effects. The latter have included pain responses, cardiovascular effects, inflammatory conditions, immune system effects, diabetes, and long-term degenerative diseases.
Selective studies are enlisted below:
Yoga nidra has been widely employed as a technique for managing stress and associated stress-induced disorders.
A randomized and controlled study on the effects of yoga nidra on feelings of general well-being, including psychological variables such as depression and anxiety, in patients suffering from menstrual irregularities showed that measures of both anxiety and depression decreased significantly in the yoga nidra practising group. Additionally, measures of positive well-being and general health and feelings of vitality also improved significantly.
A study has been done on the effect of yoga nidra practice on stress levels in the first-year nursing students. The investigators found that following 20 days of yoga nidra practice, the mean stress scores were significantly reduced supporting the conclusion that yoga nidra is a practical and easily applied stress prevention technique for students of demanding professions such as nursing.
In another study, the authors investigated the effect of yoga nidra practice on skills among wrestlers. More specifically, the researchers sought to determine if yoga nidra could improve their reaction times and anticipation times. Yoga nidra practice (45 min each day for 45 days) improved the wrestlers’ performance by improving their focus and attention. Compared to the control group, the scores for the simple visual reaction time (SVRT) and choice visual reaction time (CVRT) for the experimental group were found to be significantly faster.
A study measured the effects of yoga nidra meditation on hormonal imbalances among 75 female patients with menstrual irregularities. Compared to a matched sample of 75 controls, the yoga nidra group showed a significant rebalancing of hormonal status.
A study has been done on the effect of yoga nidra on blood pressure and psychological variables in hypertensive patients. The before and after comparisons showed that yoga nidra practice was associated with significant and beneficial changes in blood pressure as well as pulse rate, respiration rate, stress, anger, and fear. These findings support the value of yoga nidra in reducing hypertension and associated psychological conditions. An increasing number of studies have shown that yoga nidra improves heart functioning, including the lowering of blood pressure.
A recent study compared a widely practiced yoga technique, Nadi Shodhan Pranayama (Alternate Nostril Breathing against yoga nidra in terms of their respective effects on several psychophysiological measures. It was found that, compared to the nadi sodhan pranayama group, yoga nidra practitioners showed significantly greater reductions in blood pressure (systolic and diastolic), pulse rate, breath rate, and BMI, as well as reductions in anxiety as measured by the Hamilton Anxiety Rating Scale (HARS).
== Synopsis ==
Yoga nidra, also known as yogic or psychic slumber, is a state of consciousness (awareness) that occurs between waking and sleeping, similar to the “going-to-sleep” stage (hypnagogia), and is usually brought on by an active guided meditation technique. Yoga Nidra is a type of profound relaxation method (the deepest form of all meditations) that is usually performed while lying down in a supine position and consists of a series of perceptual exercises such as focusing on the breath or specific regions of the body. The practitioner follows directions for numerous types of activities without becoming distracted while remaining completely awake and concentrated. Although practitioners appear to be sleeping, their consciousness is operating at a higher degree of awareness. Thus, yoga nidra is a form of Pratyahara (withdrawal of the senses), which entails gradually dissociating and dis-identify oneself emotionally from one's body and mind. It corresponds to the higher levels of Raja Yoga.
