Purpose of the study was to determine the effect of physical relaxation technique on systolic and diastolic blood pressure. A total of sixty B. Ed students (N=60) were selected from the Christ Nagar Training College, Trivandrum. Thirty subjects in each group were randomly assigned in experimental and control group. Age ranged were 22- 30 years. For this study blood pressure (systolic and diastolic blood pressure) was selected as the dependent variables in the study. Six weeks (3days in weeks) physical relaxation was given to the experimental group. Standard procedures were followed by the researcher during pre and post data collection. Data was obtained with the help of Sphygmomanometer. For the analysis purpose dependent„t‟ was employed. Results showed significant difference between pre and post data of experimental group in systolic and diastolic blood pressure, and in case of control groups for both variables insignificant difference were found. Level of significance was set at 0.05.
