Step-by-step explanation:
The multidisciplinary field dedicated to studying interactions of how people behave, biological influences, and environmental influences, in order to improve health and well-being is called Health Psychology. Health psychology focuses on how health is affected by the interaction of biological, psychological, and sociocultural factors. Health psychologists are interested in helping individuals achieve better health through public policy, education, intervention, and research. They may research effective ways to motivate people to address patterns of behavior that contribute to poorer health.
Understanding social health is also a crucial aspect of health psychology, which considers an individual's social support network, social pressures, and stigmas, along with the broader sociocultural forces that influence well-being. The discipline of health psychology, therefore, embodies a holistic perspective on individual and community health, recognizing the intertwined nature of the physical, mental, and social domains.
