Healthcare workers are particularly vulnerable in the era of COVID‐19. Physical methods of stress relief such as yoga and massage therapy may reduce occupational stress. The objective of this systematic review and network meta‐analysis is to determine the effects of yoga, massage therapy, progressive muscle relaxation, and stretching on alleviating stress and improving physical and mental health in healthcare workers. </p> </div><div class="section"> <a class="named-anchor" id="joh212243-sec-0002"> <!-- named anchor --> </a> <h5 class="section-title" id="d12163657e273">Methods</h5> <p id="d12163657e275">Databases were searched for randomized controlled trials on the use of physical relaxation methods for occupational stress in healthcare workers with any duration of follow‐up. Meta‐analysis was performed for standard mean differences in stress measures from baseline between subjects undergoing relaxation vs non‐intervention controls. Network meta‐analysis was conducted to determine the best relaxation method. </p> </div><div class="section"> <a class="named-anchor" id="joh212243-sec-0003"> <!-- named anchor --> </a> <h5 class="section-title" id="d12163657e278">Results</h5> <p id="d12163657e280">Fifteen trials representing 688 healthcare workers were identified. Random‐effects meta‐analysis shows that physical relaxation methods overall reduced measures of occupational stress at the longest duration of follow‐up vs baseline compared to non‐intervention controls (SMD −0.53; 95% CI [−0.74 to −0.33]; <i>p</i> &lt; .00001). On network meta‐analysis, only yoga alone (SMD −0.71; 95% CI [−1.01 to −0.41]) and massage therapy alone (SMD −0.43; 95% CI [−0.72 to −0.14]) were more effective than control, with yoga identified as the best method ( <i>p</i>‐score = .89). </p> </div><div class="section"> <a class="named-anchor" id="joh212243-sec-0004"> <!-- named anchor --> </a> <h5 class="section-title" id="d12163657e289">Conclusion</h5> <p id="d12163657e291">Physical relaxation may help reduce occupational stress in healthcare workers. Yoga is particularly effective and offers the convenience of online delivery. Employers should consider implementing these methods into workplace wellness programs. </p> </div>
