... Yoganidra has been used earlier as a therapeutic option with no documented side effects. Previous studies have separately reported the effect of yoganidra on hypertension, Hs-CRP, and lipid profile [23][24][25][26]. In this study, we have assessed all the three parameters (reduction in blood pressure, Hs-CRP, and lipid profile) in one study among hypertensive subjects on pilot mode. ...
... A significant reduction in SBP and DBP was observed after 12 weeks of supervised yoganidra practice in hypertensive subjects. Our observations are in line with earlier studies [23][24][25][31][32][33][34][35]. Even though there was a gradual reduction in both SBP and DBP from baseline to endpoint. ...

Background: Yoganidra is a systematic method of promoting a state of complete physical, mental, and emotional relaxation. It is a safe, inexpensive, and very effective method of management of hypertension when used along with standard pharmacological therapy. This study aims to assess the effect of yoganidra on blood pressure (both systolic blood pressure (SBP) and diastolic blood pressure (DBP)), Hs-CRP, and lipid profile of hypertensive subjects at the time of enrollment (subjects that are hypertensive at the time of enrollment). Methods: Both treated and untreated subjects (n = 74) with hypertension (blood pressure ≥140/90 mmHg) and age between 35 and 70 years were included in this study after obtaining ICMR-NIN-IEC approval and written informed consent from all subjects. Subjects with critical illness and/or psychological disturbances were excluded from this study. The subjects in the experimental group (n = 31) practiced yoganidra for 45 minutes daily for 12 weeks under strict supervision. There was no intervention in the control group (n = 43). Weekly blood pressure was recorded in the experimental group, whereas it was performed at baseline and at endpoint for control groups. Hs-CRP and lipid profile were estimated at baseline and endpoint for both the groups. Results: A significant reduction in mean SBP from 142.9 mm Hg (SD ± 16.46) to 118.68 mm Hg (SD ± 9.21; p value 0.0001) and DBP from 89.84 mm Hg (SD ± 10.42) to 77.03 mm Hg (SD ± 6.47: p value 0.0001) was observed among the experimental group after 12 weeks of yoganidra practice when compared with the control group. A significant reduction in mean Hs-CRP (2.21 ± 1.49 to 1.06 ± 0.82 mg/L, p < 0.001 ∗∗∗ ) was observed among the experimental group. There were no significant differences between triglycerides and total cholesterol levels, whereas LDL-C and HDL-C showed a trend of improvement in the experimental group after intervention. Conclusions: In this pilot study, we observed a significant reduction in blood pressure and Hs-CRP in the yoganidra group compared with the control group. There were no significant side effects observed in the intervention group during the study period.
... He began studying the Tantric scriptures and after practicing them he constructed a new system of relaxation that was Yoga nidra. [4] Studies have stated that the practice of yoga nidra results in a hypothalamic reaction, stimulating the parasympathetic nervous system and suppressing the function of the sympathetic nervous system. [5,6,7] Yoga nidra practice brings a profoundly relaxed state of body and mind on the basis of this theory, though conscious minds are clearly alert to understand what they feel. ...
... With these phenomena, according to the stimulation or depression of the cardiac centre in the medulla oblongata, the body becomes painless, respiration becomes occasional, and the heart rate slows down. [4] In Yoga Nidra, by inducing complete physical, emotional and mental relaxation an attempt is made to activate the parasympathetic system, and slowly a new balance between the sympathetic and parasympathetic systems is achieved. This reducing stress, where the brain is completely relaxed results in mental relaxation with the practice of Yoga Nidra. ...
... Hence, if yoga nidra is practiced regularly it can be effective as a preventive measure of the silent killer Hypertension. [4] In a study by Kamakhya Kumar Yoga nidra didn't show a significant change on depression level of the patients, but the regular practice of it can be considered as an effective as a preventive measure for the hypertension. [4] Even the studies have concluded that Yoga nidra is an effective measure to reduce the level of blood pressure among elderly with hypertension [13] , cardiovascular parameters in women with PCOS [14] and has preventive, promotive and curative value. ...

This review paper aims to summarise the evidence of effect of yoga nidra on blood pressure. After assessing quality of studies, 5 articles were included in the study. Although no long-term effects were measured in these studies; yoga nidra seems to be more effective in reducing SBP and DBP. Despite all these studies the degree to which yoga may decrease blood pressure as well as the potential modifying effects of yoga intervention and type of comparison group remain unclear. To address these gaps, we still need more studies to see the long-term effect of yoga nidra on blood pressure needs to be done.
... A sample of 50 nursing students was randomly selected and data were collected using a modified stress assessment scale. The stress levels were categorized into five categories of "severe" (57-80), "high" (47-56), "moderate" (37)(38)(39)(40)(41)(42)(43)(44)(45)(46), "low" (27)(28)(29)(30)(31)(32)(33)(34)(35)(36), and "very low" (0-26). The investigators found that following 20 days of yoga nidra practice, the mean stress scores were significantly reduced (before yoga nidra, 28.82; after yoga nidra, 17.8 [p < 0.05]), thus supporting the conclusion that yoga nidra is a practical and easily applied stress prevention technique for students of demanding professions such as nursing [22]. ...
... These findings support the value of yoga nidra in reducing hypertension and associated psychological conditions. As reviewed above, an increasing number of studies have shown that yoga nidra improves heart functioning, including the lowering of blood pressure [32]. ...

Yoga nidra, also known as ‘yogic sleep’, is a simplified form of an ancient tantric relaxation technique. The most general description of the practice is that it combines guided mental imagery with a specific yoga posture called Shavasana (or “corpse pose”). The goal of yoga nidra is to promote a profound state of relaxation, which differs from sleep inasmuch as there is still an awareness of one’s surroundings. While several components of the practice have been known since ancient times, it was not until the nineteen-sixties that an updated and systematized system of practice was introduced to the public through the writings of Swami Satyananda Saraswati. Unlike other schools of yoga, which emphasize concentration or contemplation, yoga nidra’s goal is complete relaxation. As such, its advocates claim that it is suitable for all individuals, from beginners to advanced practitioners of yoga. The calm inner stillness induced by yoga nidra is claimed by practitioners to be an effective stress management tool as well as a means for attaining greater receptivity to personal resolutions. These resolutions can range from the goal of achieving self-transformation, enhancing creativity, or improving one’s learning ability. Additionally, yoga nidra is claimed to promote beneficial changes in physiological and mental health. The following narrative review summarizes the basic steps used to achieve the final state of yoga nidra relaxation as well as some recent experimental findings regarding its physiological and psychological effects. Standard research databases were searched for relevant articles. Clinical studies have shown that yoga nidra meditation is associated with positive physiological changes, including improvements in several hematological variables, red blood cell counts, blood glucose levels, and hormonal status. Two neuroimaging studies have shown that yoga nidra produces changes in endogenous dopamine release and cerebral blood flow, a further confirmation that its effects on the CNS are objectively measurable. The practice has also been shown to reduce psychometrically measured indices of mild depression and anxiety, although these benefits were not shown in an experimental study to extend to severe depression or severe anxiety.

Ischemic Heart disease is not a single disease, but a syndrome with multiple causes. In most of the cases the causes remain silent. It is of course due to the excessive tension and less relaxation. It is to be understood that ordinary sleep is not relaxation, for tensions cannot always be resolved completely in ordinary sleep. Yoga Nidra is qualitatively different relaxation. It is a 'sleep' where all the burdens are thrown off to attain more blissful state of awareness, a relaxation much more intense than ordinary sleep. However Yoga nidra can be consider as a highly effective practice for reducing blood pressure, as well as the cardiac work load of heart disease patients.
