One of the primary problems that might interfere with the mother's physical and emotional comfort and affect the baby's recovery and care is postpartum discomfort brought on by a perineum laceration. The purpose of this study was to ascertain whether using deep breathing relaxation techniques could lower the severity of postpartum pain associated with perineum lacerations. In this study, two postpartum moms with perineum lacerations at Malinau Regional Hospital in North Kalimantan were the subjects of a case study design through a descriptive methodology. During the course of treatment, deep breathing relaxation techniques were performed in accordance with protocols. Measurement of pain intensity was carried out using the Numeric Rating Scale (NRS) before and after the intervention. The results showed a decrease in the pain scale from 7 (severe pain) to 4 (moderate pain), indicating the effectiveness of the intervention. Deep breathing relaxation techniques had been proven to be safe, easy to do, and able to improve the comfort of postpartum mothers physically and psychologically. This intervention is recommended as part of complementary midwifery care in postpartum services. Keywords: Midwifery Care, Deep Breathing Relaxation, Postpartum Pain,Perineum,Laceration
