Background: Modern lifestyle leads a greater psychotechnological stress and it results increase of autonomic
imbalances. This predicts disturbance of the normal mental state and cognition. The current researchers found clear relationship between yoga practice and parasympathetic dominance.
Objectives: The purpose of the review study was to analyze the scientific literatures related to yoga and autonomic neural
Methods: Researchers collected scientific evidences through electronic online databases; PubMed, Embase, Medline,
Google scholar, Web of science, PsycINFO, Shodhganga; Europe PMC; Scopus and critically analyzed all the entire relevant articles according to the purpose of this study. After the exhaustive search and selecting the studies on the basis of
inclusion criteria, 11 full text articles of galvanic skin resistance and 75 articles related to autonomic function were
shortlisted for qualitative analysis.
Results: Yogic practices including meditation, pranayama, asana and integrated yoga increase the high frequency band
and decrease the low frequency band of the heart rate variability spectrum and it reduces the stress via limbic activity and
increases the better psychophysiological relaxation.
Conclusions: Yogic practice may enhance the vagal activity which influences autonomic flexibility.
