This clinical study will be conducted to determine the effects of musically accompanied progressive muscle relaxation and deep breathing exercises on nursing students' stress levels and bio-psycho-social responses to stress.

Do musical progressive muscle relaxation and deep breathing exercises have an impact on nursing students' stress levels and bio-psycho-social responses to stress?

After students fill in the scales, they will be randomly assigned to the experimental and control groups. The experimental group will be given progressive muscle relaxation and deep breathing exercises accompanied by music once a week for six weeks by the researcher. There will be no intervention in the control group. The scales will be reapplied to the experimental and control groups in the week after the application is completed and two weeks after the application is completed. Groups will be compared and statistical analyzes will be made.

Stress is a psychosocial factor that affects students' academic performance and well-being. The presence and level of stress have a positive or negative impact on learning and thinking, and students show behavioral, emotional, and physical symptoms of experiencing stress For this reason, it is very important for university students to apply stress reduction methods, especially non-drug methods. Progressive relaxation and deep breathing exercises with music are effective methods of coping with stress. When the literature is examined, it is seen that the use of music has recently been effective in reducing the anxiety and stress experienced by many students during the education process. At the same time, a progressive relaxation exercise integrated with deep breathing exercises helps a person to feel the difference between tension and laxity in the body and allows the person to learn to relax on their own, thus reducing physical and emotional tension. Thus, the individual moves away from disturbing stimuli that reduce the quality of life such as anxiety, pain, and stress. In accordance with the nursing education program carried out with theoretical and practical application course hours, students considering the stress they are exposed to and the behavioral, emotional, and physical problems that arise with stress, there is a need for research that uses mind-body applications to support nursing students. At the end of the research, it is foreseen that the stress levels of nursing students and the symptoms seen due to stress can be reduced.

Method: The universe of the study will consist of 2nd, 3rd, and 4th year nursing undergraduate students who are studying and interning at Gülhane Nursing Faculty of Health Sciences University in 2022-2023. As a result of the power analysis, the minimum sample size was found to be 140 students, with 70 students in each group. During the study, in order to strengthen the results of the research and increase reliability, it was determined that the sample was 154 students with 77 experiments and 77 control groups with an increase of at least 10%. Student sampling; After each class is evaluated as a layer, proportional stratification will be taken by sampling method according to layer weight (number of students). 44 students from 2nd grade, 52 students from 3rd grade, and 58 students from 4th grade will participate in the research. Students have completed the Voluntary Consent Form for Nursing Students, Personal Information Form, Perceived Stress, and Bio-psycho-social Response Scale, then students who meet the inclusion criteria will be randomly assigned to intervention and control groups. Exercises will be applied to the intervention groups for 6 weeks. There will be no intervention in the control group. At the end of 6 weeks and 2 weeks after the last application (8. Weeks) intervention and control groups will refill the scales.
