Stress and the Immune System

Researchers at Stanford University have been studying acute stress and the immune system's response. The body responds to acute stress by mobilizing the immune system in order to prepare for healing a possible injury. This is a good thing and short term stress, minutes or a few hours, is good for the body and can boost the immune system. this is perhaps one way exercise helps prevent infections. Chronic, unrelenting stress has the opposite effect. A wonderful book on the effects of chronic stress is Why Zebras Don't Get Ulcers by Robert Sapolsky. He is also on the faculty at Stanford.
