Health is a concept that is central to nurse education and nursing practice. It remains a dynamic concept, however, that has evolved over time and can be examined from contrasting perspectives. This article explores the various perspectives of health, for example lay concepts of health and factors such as happiness and well-being and their effect on people’s perceptions of health. It is recommended that nurses use a person-centred approach to explore patients’ concepts of health, which can influence their capacity to self-care.
