Women usually believe that labor is a physiological process with severe pain.[1] Most women are afraid of labor pain, which results in 8-22% of unnecessary cesarean sections.[2] Compared with vaginal labor, cesarean section is accompanied by increased risk of uterine infections, bleeding, urinary tract infection, and thromboembolism in mothers.[3] Most women require pain relief during their labor, and the pain relief strategies include application of pharmacological and non-pharmacological methods.[4] Labor pain management with minimal complications is one of the major challenges of the health team, and using non-pharmacological methods of pain relief is highly considered by both obstetricians and women.[5]
