Previous reports have revealed that non-pharmacological approaches such as aromatherapy, massage, meditation, music therapy, breathing exercises, yoga and progressive muscle relaxation exercises (PGE) have been used to reduce stress and fatigue of individuals and improve their well-being.~However, there have been limited studies that directly focus on supporting intensive care nurses who face serious problems with intense work tempo, experience excessive stress, headache, tension, fatigue, are open to psychosocial problems such as anxiety, depression and burnout.~Besides, till date, no study has been conducted to determine the effects of progressive relaxation exercise on occupational stress, headache and well-being for intensive care nurses.~The present study investigates the effects of progressive muscle relaxation in a single-site, 2-arm, assessor-blinded randomized, controlled study of 100 intensive care nurses.~Arm 1: relaxation; Arm 2: Attention matched control. The investigators hypothesize that progressive muscle relaxation will decrease the severity of occupational stress and headache and improve well-being.
Nurses who intensive care unit will be entered. Participants will be randomized to one of two study arms:~Arm 1: Progressive muscle relaxation; Arm 2: control. Hypothesis: Progressive muscle relaxation will decrease occupational stress, headache and improve well-being.
