Yoga Nidra as a Non-Pharmacological Intervention for Improving Mood

Alvin Sherman Library

Yoga Nidra, a meditative practice blending relaxation and guided imagery, has shown potential as a non-invasive, accessible intervention for stress and mood disorders. This study investigated the effects of Yoga Nidra (iRest) on psychological mood and physiological markers, focusing on its neural engagement and sleep modulation in a sample of 21 college-age participants (6 males). Participants completed a Yoga Nidra condition involving EEG and EDA monitoring, followed by mood assessments using the Profile of Mood States (POMS). Neural activity patterns indicated that higher alpha and beta wave engagement during Yoga Nidra were associated with improved vigor and reduced fatigue and confusion (p < 0.05). Conversely, theta and delta activity, indicative of deeper sleep states, correlated with increased confusion and tension. Sleep stage analysis revealed a nuanced relationship: N1 sleep correlated with reduced confusion, while N2 sleep negatively impacted vigor and mood (p < 0.05). The findings suggest that active engagement during Yoga Nidra optimizes its mood-enhancing effects, whereas deeper sleep states (indicative of sleep debt prior to Yoga Nidra induction) may counteract these benefits. This provides insights into the physiological mechanisms underpinning Yoga Nidra’s efficacy. This study also underscores Yoga Nidra’s dual role in stress reduction and mood improvement, offering promising implications for its integration into mental health and wellness programs. Further research is needed to explore its long-term benefits and applications across diverse populations.
