Health communication is an interdisciplinary field of study and practice focused on the role of human communication in health outcomes and healthcare contexts. It investigates the creation, dissemination, and reception of health-related information across various levels, from interpersonal interactions to mass media and digital platforms, examining the interplay of messages, channels, and contexts. The field seeks to inform, persuade, and empower individuals and communities, ultimately aiming to improve health literacy, promote healthy behaviors, and enhance public health initiatives.
