In light of escalating global mental health concerns and the limitations of current allopathic treatments, there is an urgent demand for effective population-wide approaches to promote mental well-being. Addressing stress effectively holds the potential to enhance overall wellness and prevent illnesses. The global rise in the popularity of yoga stems from its accessibility, affordability, and acceptability as a holistic mind-body practice. Amid preferences for self-directed care over clinical interventions, perceived efficacy surpassing medication, minimal side effects, and unresponsiveness to drugs, individuals are increasingly turning to yoga for mental health enhancement. This practice minimizes side effects and offers cost-effectiveness compared to pharmaceuticals and psychotherapy while improving physical fitness and self-sufficiency. This article briefly explores the substantiated evidence supporting yoga's role in mental health promotion, illness prevention, and treatment for depression.
