Background: Yogic techniques have been seen to improve an individual’s overall personal development involving body, mind and soul. Evidences suggest that alternate nostril breathing i.e. pranayama technique for a certain time everyday affects cardiovascular reflex control system and also helps in controlling excessive weight. Material and Methods: 40 hypertensive subjects in the age group of 35-70 years were subjected to alternate nostril breathing exercise sitting in Padmasana position for 10 minutes everyday. Results: Alternate nostril breathing exercise reduced the sympathetic activity and increased the parasympathetic activity leading to improvement in vagal tone as shown by statistically significant decrease (P<0.001) in systolic blood pressure, diastolic blood pressure and pulse rate.
