The Cold Pressor Test (CPT) was introduced as a standard incentive for studying the vasomotor response (Hines and Brown 1932). Hyper-reactors were the subjects in his study who responded more strongly to CPT, Participants who show hyper reactivity to Cold pressor test (i.e. subjects showing 25 mmHg increase in systolic blood pressure along with 20 mmHg increase in diastolic blood pressure).They proposed that these hyper reactive could be candidates for hypertension in the future. Increased occurrence of these diseases could be attributed to an asymmetry in sympathetic and parasympathetic stimulation. Control or adaptation of breathing or breathing workouts i-e yoga are thought to be beneficial in the treatment of such disease. Although Yoga techniques proven to be effective in treating stress related disorders but it is time consuming and young population because of their busy routine couldn't be able to take out time for their health related issues. This study introduces very simple exercise in the form of left nostril breathing which decreases sympathetic activity and increases parasympathetic activity. It is inversely proportional to stress induced response of the body, it is very easy to perform and can be done at any time, and if found significantly effective for stress disorder ,it could be used in daily routine by our youth to get themselves prevented from major risk factors of CVD's particularly hypertension. This study will identify participants with a high potential risk of developing hypertension in the future by administering Cold pressor test, additionally the effects of left nostril breathing intervention on hyper reactive participants would be observed and if found significant, it would be a major breakthrough in primary prevention of hypertension.
The purpose of this study is to evaluate the effects of left nostril breathing in young females having cardiovascular hyper reactivity to cold pressor test.Although,limited literature exist regarding hyper reactivity towards stress induced test in our youth and its effective and easy treatment in the form of left nostril breathing which could proves to be beneficial for our youth.
