Abstract

Introduction: With modern life style, in the present environmental conditions the prevalence of prehypertension & hypertension is high and is a significant risk factor for cardiovascular diseases and cerebrovascular accidents. Deep breathing exercise is a useful non– pharmacological adjunct in lowering blood pressure and heart rate.
Aim and Objective: To evaluate the effectiveness of deep breathing on blood pressure parameters in patients with prehypertension and hypertension.
Materials and Method: The study group I comprised of 60 pre-hypertensive participants in the age group 30-50 years & group II with another 60 hypertensive patients attending NCD (non-communicable disease) clinic at Kanyakumari Govt. Medical College Hospital. Both the pre-hypertensive & hypertensive groups consist of a control group with 30 participants and experimental group with 30 participants. The experimental group participants were taught and insisted to practice deep breathing exercise regularly. The blood pressure and heart rate were monitored at 0, 4, 8, 12 week intervals in both the experimental and control group.
Results: Data is analysed using paired and unpaired ‘t’ test. A highly significant reduction in both systolic and diastolic blood pressure was found in the experimental group compared with the control group individuals. Beneficial effect started to appear at 4 weeks.
Conclusion: Regular practice of deep breathing exercise is effective in reducing systolic and diastolic blood pressure by enhancing parasympathetic activity and reducing sympathetic excitability.
