Brief summary

The hypothesis was that a one-year experience of choir singing once a week is more beneficial than group discussions to saliva concentration of testosterone.

Detailed description

The project aimed to study the health effects of regular choir singing for persons who are in a psychosomatic condition (Irritable Bowel syndrome - IBS). A group of IBS patients were randomized to choir singing or an information group were followed during one year with biological and psychosocial assessments. The choir group participated in various relaxation, breathing and vocal exercises with the choir leader, and received the material To live with IBS for home studies. At the same time a comparison group with IBS patients meet in groups, studying and discussing on the same materials under the direction of a group leader. Both groups meet once per week.
