This document discusses relaxation techniques. It defines relaxation as a state where muscle tension and mental stress are reduced through conscious effort. Relaxation can be general, involving the whole body, or local, targeting specific muscle groups. Several factors like muscle tone, posture, movement, and mental state can affect relaxation. Techniques to achieve general relaxation include assuming supported, comfortable positions and creating a restful atmosphere. Specific techniques discussed are autogenic training, progressive muscle relaxation, and the contrast method, which involve sequentially contracting and relaxing different muscle groups.
