Physiological data from 550 students showed that high anxiety is linked to irregular, shallow breathing and EEG changes—increased beta and decreased alpha power. A Kriya yoga intervention (regulated pranayama and calming postures) for a subset of anxious students reduced anxiety, increased alpha activity, decreased high-beta activity, and improved respiratory signals. A Random Forest classifier distinguished high-anxiety from post-intervention states with 84% accuracy. The authors propose that combining yoga, physiological monitoring, and machine learning offers a nonpharmacological approach to mental health and emotional management.
