Immediate Hemodynamic changes on performing slow uninostril and alternate nostril breathing pranayamas in normotensive adults

Yoga is an ancient Indian art and science ofmaintaining health and wellbeing. Pranayamas are the breathing techniquesexplained in yoga. Pranayamas have been reported to have beneficial effects onhealth by reducing psychosocial stress which are mediated through improvementof autonomic functions[1,7,9]. Recently, it has been seen that psychosocialstress levels are on the rise in modern society due to change in lifestyle.Chronic psychosocial stress is associated with increased the risk of Noncommunicable diseases including Hypertension[21]. Many studies haveshown that the slow breathing practices can cause modest reduction in bloodpressure[22-24]. Earlier, studies have been conducted on immediateeffects of Uninostril and alternate nostril breathing on Blood pressure. Theysuggest differential nostril breathing produces distinct autonomic changes[6,14].But they involved regular practitioners of Yoga[6,14]. This studyintends to study the immediate hemodynamic effects of slow uninostril and slowalternate nostric Yoga breathing practices on 132 subjects. This study is toassess the physiological effects of certain modified Yoga breathing practiceson hemodynamic parameters like Systolic Blood Pressure (SBP), Diastolic BloodPressure (DBP), Mean Pressure (MP) and Pulse Rate (PR), in healthy adults whoare non regular practitioners of Yoga. In this study, slow Yogic Uninostrilbreathing practices like Chandra-Anulom vilom (CAV) or Left Nostril breathing,Surya-Anulom vilom (SAV) or Right Nostril breathing, Anulom-Vilom (AV) orAlternate nostril breathing are used as intervention.
