Abstract: Nausea and vomiting during pregnancy can have a profound effect on the quality of life and social performance of the primigravida women. So, the aim of this study was to: Determine the effect of Jacobson and Benson Relaxation techniques on nausea and vomiting among primigravida women. Subjects and Method: A quasi-experimental research design was utilized to conduct this study on 100 primigravida women. The study was conducted at the antenatal out-patient clinics of Tanta University Hospitals, El-Menshawy General Hospital and Three Maternal and Child Health (MCH) Centers at Tanta city, Egypt. Three tools were used: Tool (I):Pregnant women's knowledge regarding nausea and vomiting assessment sheet, Tool (II): Modified 24-hour Pregnancy-Unique Quantification of Emesis (PUQE) & Tool (III): Visual Analog Maternal Satisfaction Scale. Results: The total severity of nausea and vomiting according to (PUQE) index was significantly improved from moderate among (80%& 78% respectively) of the studied pregnant women of both Jacobson's and Benson's groups before interventions to mild among (54%& 52% respectively) of them one week post intervention. As well as, (80%& 78% respectively) of the studied pregnant women were highly satisfied with Jacobson and Benson relaxation techniques without statistically significant differences between the two groups (P= 0.207). Conclusion:The severity of nausea and vomiting was significantly reduced among the primigravida women after the application of Jacobson and Benson relaxation techniques with high satisfaction among the studied pregnant women of both groups. Recommendations: Jacobson and Benson relaxation techniques should be integrated into the management of nausea and vomiting during pregnancy.
