Health psychology is the study of psychological and behavioral processes in health, illness, and healthcare.[1] The discipline is concerned with understanding how psychological, behavioral, and cultural factors contribute to physical health and illness. Psychological factors can affect health directly. For example, chronically occurring environmental stressors affecting the hypothalamic–pituitary–adrenal axis, cumulatively, can harm health. Behavioral factors can also affect a person's health. For example, certain behaviors can, over time, harm (smoking or consuming excessive amounts of alcohol) or enhance (engaging in exercise) health.[2] Health psychologists take a biopsychosocial approach. In other words, health psychologists understand health to be the product not only of biological processes (e.g., a virus, tumor, etc.) but also of psychological (e.g., thoughts and beliefs), behavioral (e.g., habits), and social processes (e.g., socioeconomic status and ethnicity).[2]

By understanding psychological factors that influence health, and constructively applying that knowledge, health psychologists can improve health by working directly with individual patients or indirectly in large-scale public health programs. In addition, health psychologists can help train other healthcare professionals (e.g., physicians and nurses) to apply the knowledge the discipline has generated, when treating patients. Health psychologists work in a variety of settings: alongside other medical professionals in hospitals and clinics, in public health departments working on large-scale behavior change and health promotion programs, and in universities and medical schools where they teach and conduct research.

Although its early beginnings can be traced to the field of clinical psychology,[3] four different divisions within health psychology[4] and one related field, occupational health psychology (OHP),[5][6][7][8] have developed over time. The four divisions include clinical health psychology, public health psychology, community health psychology, and critical health psychology.[4] Professional organizations for the field of health psychology include Division 38 of the American Psychological Association (APA),[9] the Division of Health Psychology of the British Psychological Society (BPS),[10] the European Health Psychology Society (EHPS),[11] and the College of Health Psychologists of the Australian Psychological Society (APS).[12] Advanced credentialing in the US as a clinical health psychologist is provided through the American Board of Professional Psychology.[13]
