Health psychology evaluates the role of behavior in the etiology of disease, develops predictions of behaviors that are harmful to health, and promotes healthy behaviors. Its epistemological assumption, the biopsychosocial model, involves the interaction of biological, psychological and social analysis of health and disease. Chronobiology is concerned with the investigation of recurrent temporal physiological and behavioral variables as well as the temporal adjustment of these variables to the environment and their social demands. The purpose of this theoretical article was to expose the intersection between these two areas showing that both contribute for the understanding of the biopsychosocial effects on health, for the early identification of those at risk and for the prevention of healthy behaviors to deal with conflicting situations, in addition to its role in development programs of health promotion, studies and interventions in the community and public health. These specialties are fundamentally interdisciplinary, involving physiological, behavioral, cognitive, educational and environmental knowledge, making this intersection consolidated.
