Stress and Health: Biological and Psychological Interactions is a brief and accessible examination of psychological stress and its psychophysiological relationships with cognition, emotions, brain functions, and the peripheral mechanisms by which the body is regulated. Updated throughout, the Third Edition covers two new and significant areas of emerging research: how our early life experiences alter key stress responsive systems at the level of gene expression; and what large, normal, and small stress responses may mean for our overall health and well-being.

History of the Concept of Stress
- The earliest study of living things recognized that organisms could be viewed as having machinelike functioning.
- The modern science of physiology was based on the principle that spontaneous activity of living organisms was not based on an invisible life force. Instead, living things have to be able to respond to demands from the environment to sustain life. To do this, they maintain their internal environment in a stable state.
- The concept of stress developed from the recognition that severe demands on homeostasis called for equally severe responses to maintain homeostasis.
- Prolonged effort to maintain homeostasis when the stressor continues without removal can have long-term consequences for the individual.
