Effect of yoga breathing techniques on brain activity

Completed

Conditions: Participants with normal health of both gender (based on Semi structured interview for health conditions)

Brief Summary: The aim of this study is to assess the effects of (i) Yoga bellows-type breathing (*bhastrika pranayama*), (ii) High frequency yoga breathing (*kapalabhati pranayama*) and (iii) Humming bee breathing (*bhramari pranayama*) techniques on thalamo-cortical and autonomic activity in normal healthy participants. Assessments used in this study are: (i) Middle latency auditory evoked response (MLR) for thalamo-cortical activity using Nicolet EDX system U.S.A., (ii) Heart rate variability (HRV) and respiration rate (RR) for involvement of autonomic nervous system using MP 45 Biopac Student Lab, BIOPAC System Inc, U.S.A, (iii) The brief mood introspection scale (BMIS) for mood, (iv) Nijmegen questionnaire (NQ) for breathing pattern and (v) Visual analogue scale (VAS) for interventional quality. This study will help to understand if the characteristics of respiration modify the thalamo-cortical activity as well as involvement of autonomic nervous system to modify this.
