Therefore, a method that can be used to reduce stress levels and improve blood pressure is needed. The relaxation technique of the slow deep breathing exercise (SDBE) method is thought to be able to reduce stress levels.<br> <strong>Objectives. </strong>Researchers are interested in the effect of slow, deep breathing exercise on stress levels and blood pressure.<br> <strong>Methods. </strong>The study used a quasi-experimental design. The research subjects, totaling 40 people, were selected using purposive sampling. Subjects were divided into 2 groups: a control group of 18 people and an intervention group of 22. The control group used the simple relaxation technique, while the intervention group used SDBE. SDBE intervention was carried out every day for 3 weeks. Data on stress levels and blood pressure were taken before and after the intervention. Measurement of stress level using Perceived Stress Scale. Measurement of blood pressure using auscultation methods. Data were analyzed using dependent t-test and independent t-test.<br> <strong>Results. </strong>There was a significant decrease in stress level (p=0.000), systolic blood pressure (p=0.019), and diastolic blood pressure (p=0.000) after SDBE intervention. While in the control group, there was only a significant decrease in diastolic blood pressure (p=0.039). Compared to the control group that used simple relaxation techniques, the SDBE intervention group reduced stress levels better (p=0.000).<br> <strong>Conclusion. </strong>Slow, deep breathing exercise reduce stress levels and blood pressure in medical faculty students. Slow, deep breathing exercise is more effective in reducing stress than simple relaxation techniques.</div> Slow Deep Breathing Exercise, Stress Level, Systolic Blood Pressure, Diastolic Blood Pressure, Medical Students 0 0 http://aassjournal.com/browse.php?a_code=A-11-1682-3&slc_lang=en&sid=1 Susiana Candrawati susiana.candrawati@unsoed.ac.id 100319475328460015267 100319475328460015267 Yes Department of Physiology, Faculty of Medicine, University of Jenderal Soedirman, Purwokerto, Indonesia Erlangga Aditya Ganesha erlangga.ganesha@unsoed.ac.id 100319475328460015268 100319475328460015268 No Faculty of Medicine, University of Jenderal Soedirman, Purwokerto, Indonesia Rizqi Hendra Setiawan rizqi.setiawan@unsoed.ac.id 100319475328460015269 100319475328460015269 No Faculty of Medicine, University of Jenderal Soedirman, Purwokerto, Indonesia Dyah Woro Dwi Lestari dyah.lestari@unsoed.ac.id 100319475328460015270 100319475328460015270 No Department of Bioethics, Faculty of Medicine, University of Jenderal Soedirman, Purwokerto, Indonesia Wiwiek Fatchurohmah wiwiek.fatchurohmah@unsoed.ac.id 100319475328460015271 100319475328460015271 No Department of Physiology, Faculty of Medicine, University of Jenderal Soedirman, Purwokerto, Indonesia
