BEHAVIORAL MEDICINECenters for Disease Control (CDC) claim that half

of the deaths in the US are due to people’s behaviors (smoking, alcoholism, unprotected sex, insufficient exercise, drugs, and poor nutrition).

Psychologists and physicians have thus developed an interdisciplinary field of

behavioral medicine that integrates behavioral knowledge with medical knowledge.

Stress can be adaptive. In a fearful or stress- causing situation, we can run away

and save our lives. Stress can be maladaptive. If it is prolonged (chronic

stress), it increases our risk of illness and health problems.
