Participants were randomly assigned via computer, including nurses from a corona epidemic hospital who consented. The intervention group practised progressive muscle relaxation (PMR) for 25 - 30 minutes daily for 4 weeks, whereas the control group received no intervention. Both groups completed the Perceived Stress Scale (PSS) and the State-Trait Anxiety Inventory (STAI) online pre- and post-intervention. Data were analysed with SPSS 23.0 using the Shapiro-Wilk test for normality, Independent samples t-test for continuous variables, chi-square test for categorical variables, and paired samples t-test for pre- and post-test comparisons in the intervention group (P < 0.05).<br> <strong>Results:</strong>Statistically significant decreases in PSS and STAI levels were observed in the intervention group (P = 0.006 and P = 0.002, respectively). No significant changes were seen in the control group. The intervention group showed a significant decrease in STAI scores compared to the control group (P = 0.037).<br> <strong>Conclusions:</strong>Results showed that web-based progressive relaxation significantly reduced stress and anxiety in nurses, suggesting that accessible interventions can improve mental health in high-stress healthcare settings.</span></span></div> Covid-19 Anxiety,Nurses,Pandemics,Relaxation Exercises,Stress 0 0 http://mcj.bums.ac.ir/browse.php?a_code=A-10-1-307&slc_lang=en&sid=1 Yurdagül Günaydın yurda_gul@windowslive.com 10031947532846004924 10031947532846004924 Yes Faculty of Health Sciences, Tarsus University, 33000, Mersin, Turkey Tülay Aytekin Aydın 10031947532846004925 10031947532846004925 No Elazığ Fethi Sekin City Hospital, 23100, Elazığ, Turkey Gülcan Bahçecioğlu Turan 10031947532846004926 10031947532846004926 No Faculty of Health Sciences, Fırat University, 23100, Elazığ, Turkey Züleyha Kılıç 10031947532846004927 10031947532846004927 No Zübeyde Hanım School of Health, Niğde Ömer Halisdemir University, 51000, Niğde, Turkey Yunus Hacımusalar 10031947532846004928 10031947532846004928 No Kayseri City Hospital, 38000, Kayseri, Turkey Ayşe Aydınlı 10031947532846004929 10031947532846004929 No Faculty of Health Sciences, Süleyman Demirel University, 32000, Isparta, Turkey
