Abstract
Background: Yoga nidra is a systematic method of inducing complete physical, mental, and emotional relaxation, and in this state, the relaxation is achieved by turning inward, away from outer experiences. It has been used in patients of menstrual abnormalities, post-traumatic stress disorder, diabetes, anxiety, and depression but little is known about its effect on polycystic ovarian syndrome (PCOS).

Aims and Objective: The aim and objective of this study are to assess the 12 weeks of yoga nidra intervention on resting cardiovascular parameters among PCOS patients.

Materials & Methods: The present study includes 40 PCOS women with the age between 18 and 35 years. Yoga nidra intervention was given by yoga and naturopathy physician to the patients in the lying position daily once for the period of 40 min. Resting cardiovascular parameters such as systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were recorded in the standard manner before after the intervention.

Results: There was a significant (P < 0.01) reduction in resting cardiovascular parameters such as HR (from 79.46 ± 6.80 to 72.84 ± 7.24 bpm), SBP (from 128.70 ± 8.46 to 122.0 ± 9.26 mmHg), and DBP (from 78.42 ± 6.42 to 72.0 ± 8.72 mmHg).

Conclusion: The present study showed favorable changes in blood pressure, HR, and other anthropometric parameters in PCOS after 12 weeks of yoga nidra intervention.
Still, further studies are needed to carry out with proper sample size and better study design to validate these effects.
