Abstract
Abstract: Yoga has transcended its traditional Indian roots to become a global therapeutic practice with measurable neurobiological effects. Emerging neuroscientific research demonstrates that yogic practices that comprising asana (postures), pranayama (breath regulation), and dhyana (meditation) induce structural and functional brain changes associated with improved mental health, emotional stability, and cognitive performance. Mental health disorders such as depression, anxiety, and chronic stress have emerged as global health challenges, significantly affecting productivity, emotional stability, and overall quality of life. Despite advances in modern medicine, the neurobiological understanding of mind–body interventions such as yoga remains underexplored in mainstream neuroscience. Yoga, an ancient Indian system integrating postures (asanas), breathing techniques (pranayama), and meditation (dhyana), acts as a holistic regulator of both the central and autonomic nervous systems. By analysing recent neuroimaging and biochemical studies, this research identifies significant correlations between yoga practice and enhanced gamma-aminobutyric acid (GABA) activity, increased serotonin and dopamine levels and reduced cortisol secretion. These neurochemical modulations correspond to decreased anxiety, improved mood regulation, and enhanced cognitive performance. Functional MRI and EEG evidence further indicate that yoga strengthens the prefrontal cortex, hippocampus, and insular connectivity while reducing amygdala overactivation — mechanisms central to emotional regulation and stress resilience. Physiological parameters such as heart rate variability and blood pressure also show measurable improvements, reflecting balanced sympathetic–parasympathetic interactions. This paper concludes that yoga operates as a neurobehavioral modulator, inducing adaptive neuroplastic changes and restoring psychophysiological harmony. The integration of yoga into public health and mental wellness programs could provide a sustainable, evidence-based model for enhancing emotional stability, cognitive clarity, and resilience in an increasingly stressful world.
