VITAL ASPECT OF RESPIRATION AND CHANGE IN BRAIN SIGNAL DURING MEDITATION USING EEG AND MACHINE LEARNING
International Journal of Apllied Mathematics October 22, 2025 S. Dinesh Nayak
Practicing breathing exercises, such as Kriya Yoga, can enhance antioxidant status, reduce free radicals, and boost the immune system, making individuals less vulnerable to disease. Changes in EEG and respiration signals after breathing exercises indicate qualitative improvements in life. This research evaluates EEG and breathing data from inexperienced meditators, former yoga practitioners, and monks after a specific week of meditation. Using spectral analysis, phase analysis, and classification, the study assesses whether breathing feature vectors and EEG data serve as reliable objective markers of meditation skill, employing Decision Trees, Support Vector Machines, and Random Forest classifiers to examine mindfulness meditation as a mental exercise for sustaining relaxation.
