Relaxation Exercise in Patients With COVID-19

The intervention group performed two types of relaxation techniques, that have shown their positive effects on immune functions, including progressive muscle relaxation exercise (PMRs)16 and cognitive-behavioral stress management (CBSM)32. We used two types of relaxation techniques to produce maximum effects of relaxation techniques within the limited period of COVID-19 quarantine (2 weeks). the control groups did not receive any treatment during the study; however, they were treated afterwards.
