Epigenetics investigates how reversible molecular mechanisms DNA methylation, histone modification, and microRNA regulation regulate gene expression without modifying the DNA sequence. Over the past decade, yoga and meditation, traditional Indian practices designed to synchronise body, breath, and awareness, have surfaced as effective behavioural regulators of these processes. This systematic review (2010–2025) consolidates forty-four peer-reviewed human studies to investigate the effects of yoga and meditation on epigenetic regulation concerning stress, inflammation, and ageing.
Results indicate substantial decreases in DNA methylation of FKBP5 and NR3C1, diminished histone deacetylase (HDAC) activity, elevated histone acetylation associated with neuroplasticity, and modified microRNA profiles regulating immunological and stress responses. Multi-omics investigations indicate increased telomerase activity and activation of longevity-related genes, including SIRT1 and TERT, implying yoga’s contribution to biological rejuvenation.
Physiologically, these molecular alterations correspond to decreased cortisol levels, equilibrated autonomic function, and enhanced immunological efficacy. Philosophically, they reflect samatvam the yogic principle of equilibrium between mind and body. Despite design diversity and restricted sample numbers, consistent evidence suggests that yoga and meditation function as behavioural epigenetic regulators, converting mental awareness into genomic stability.
The amalgamation of ancient yogic principles with contemporary molecular biology has the potential to transform preventative care via affordable, nonpharmacological methods for fostering resilience and comprehensive well-being.
