摘要Objective: To explore how relaxation reduce the effect of stress in Iranian nursing students. Methods: A total of 40 nursing students were randomly selected and divided into two groups of test and control each with 20 students. An exam questionnaire consisting of the stress test of Spilberger and control of physiological determinants (blood pressure, pulse respiration, temperature) was performed to two groups. The practice of relaxation continued for two weeks and three times a day. Data were collected and analysed using t-test and Chi-square. Results: Two groups did not show any difference in relation to the average of physiological determinants before and after investigation. However, pulse was significantly different between the two groups. The average scores of stress be-fore and after relaxation were significantly differed between the two groups investigation so that the level of stress was reduced in the test group (t= 2.5, df =39, P= 0.02). Conclusion. To alleviate stressors associated with clinical practice and create a healthy work environment for practice it is rec-ommended that nursing students have some relaxation before entering practical environments.
