Effect of Yoga on Stress R Brain Signal Analysis

Abstract

Stress can significantly enhance the performance of the human individuals. Though moderate levels of stress can be useful in maintaining attention, too much stress impairs working performance; this appalling figure determines the seriousness of this problem pertaining to stress level of the students. Young Indians living in wealthier and more educated regions are more likely to suffer from such kind of problems. Cognitive reactions of stress result in the inability to concentrate and however relaxation therapies significantly reduce the stress level in students. Moreover, research has shown PMBSR (Physical Mindfulness Based Stress Reduction) to be effective in reducing pain intensity, chronic pain, and stress. Yoga can lead to neurological changes, foster physiologic health benefits through improved immune function and reduced arousal. The research revealed that the school children s, NCC Cadets and the surgeons improved the physical and cognitive strength after practicing the Yoga for the proper time duration. The stress was identified based on the Pystack (Go- NoGo) test and brain signal before and after yoga activity, pre yoga- post yoga and the brain signal was acquired using the 24 channel EEG (Electroencephalogram) device and the distraction noises from the signal was reduced and classified using Independent Compound Analysis (ICA) tool. Yoga energizes the pre-frontal lobes of the human brain and in time, the limbic system becomes harder to arouse. This results in behavioral changes including better physical, ego, integrity, psychological problems, less depression and anxiety and better social skills. Other positive outcomes linked to Yoga practices include effective functioning, academic performance, concentration, perceptual sensitivity, reaction time, memory, self control, empathy, and self-esteem newline
