The Vagus Nerve and Yoga: Parasympathetic Activation Through Practice

Abstract

The vagus nerve, the longest cranial nerve in the human body, plays a crucial role in parasympathetic nervous system activation and overall physiological regulation. This review examines the relationship between yoga practice and vagal tone enhancement, exploring the mechanisms through which yoga stimulates parasympathetic activation. Through analysis of current research, this paper demonstrates that yoga practices, particularly breathing techniques (pranayama), meditation, and specific postures (asanas), significantly increase vagal tone and promote parasympathetic dominance. The implications for stress reduction, cardiovascular health, immune function, and overall well-being are discussed. Findings suggest that regular yoga practice serves as an effective intervention for enhancing vagal function and supporting autonomic nervous system balance.
