This study aimed to evaluate the effectiveness of hot application as a non-pharmacological pain management strategy for primigravida women during the active phase of labor. Utilizing a randomized controlled trial design, participants were allocated to either an intervention group receiving hot application or a control group receiving standard care, with labor pain intensity assessed using the Modified McGill Pain Scale. The results demonstrated a statistically significant reduction in sensory, affective, and total pain scores in the intervention group compared to the control group, indicating the effectiveness of hot application in alleviating labor pain. Future research should explore the optimal duration and frequency of hot application, its effects across different labor stages and parities, and its potential impact on labor outcomes to further inform evidence-based practice and enhance pain management options for laboring women.
