This review article explores the significant role of nurses and midwives in enhancing maternal postpartum psychological health. The postpartum period is a critical phase in a woman's life, characterized by various physical, emotional, and psychological changes. Maternal mental health during this period is crucial not only for the well-being of the mother but also for the healthy development of the newborn. Nurses and midwives play a pivotal role in providing comprehensive care and support to new mothers, thereby influencing their postpartum psychological well-being. This review synthesizes existing literature to examine the impact of nursing and midwifery interventions on maternal mental health outcomes during the postpartum period. The postpartum period is a vulnerable time for many women, characterized by a heightened risk of developing mental health issues such as postpartum depression and anxiety. Nurses and midwives, as frontline healthcare providers, are uniquely positioned to identify and address these challenges early on, thereby improving maternal outcomes. Through a combination of emotional support, education, and counseling, nurses and midwives can help new mothers navigate the complexities of the postpartum period and promote positive mental health. Studies have shown that maternal mental health is closely linked to various factors such as social support, self-esteem, and coping mechanisms. Nurses and midwives can leverage their expertise to assess these factors and develop tailored interventions to support maternal psychological well-being. By fostering a trusting and empathetic relationship with new mothers, healthcare providers can create a safe space for women to express their concerns and seek guidance on coping strategies. Furthermore, the integration of evidence-based practices and protocols within healthcare settings can enhance the effectiveness of nursing and midwifery interventions in improving maternal postpartum psychological health. By staying abreast of the latest research findings and guidelines, nurses and midwives can deliver high-quality care that meets the unique needs of each mother. Collaborative efforts between healthcare professionals, policymakers, and community organizations are essential to creating a supportive environment for new mothers and promoting positive mental health outcomes during the postpartum period.
