Emotional intelligence (EI) is the ability to perceive, understand, manage, and regulate emotions, both in oneself and in others. It plays a crucial role in personal and professional success, influencing how individuals handle interpersonal relationships, make decisions, and cope with stress. On the other hand, breathing techniques are exercises designed to regulate breathing patterns, often used to reduce stress, improve emotional regulation, and enhance overall psychological well-being. Despite increasing interest in both emotional intelligence and breathing techniques, there remains a significant gap in research connecting these two fields. Specifically, the potential for breathing techniques to improve emotional intelligence and the physiological underpinnings of EI remains largely unexplored. This article aims to review the existing literature on emotional intelligence and breathing techniques, identify gaps between them, and suggest directions for future research to better understand how these domains may intersect and inform each other.
