Pschoimmunology

Description

Recent studies in the field of psychoimmunology suggest a link exists between behavioral events and the functioning of one's immune system. Data shows the results of a study on 12 subjects who were monitored during three distinct activities. The first activity consisted of neutral activity such as reporting tasks. During the second activity, subjects listened to audiotape exercises relating to images of heaviness, warmth in the body, relaxation, suggestions to remember happy events, etc. The third activity included a nonaudio tape follow up stimulus consisting of continued relaxation as in activity 2 and a verbal discussion of the positive aspects of the audiotape.
