Mind-body medicine uses the power of thoughts and emotions to influence physical health. The key to any mind-body technique is to "train" the mind to focus on the body without distraction. In this state of "focused concentration," a person may be able to improve their health. Some of the most commonly used techniques include biofeedback, cognitive-behavioral therapy (CBT), and relaxation techniques (autogenic training, progressive muscle relaxation, meditation, hypnosis, and spirituality). The goal of mind-body techniques is to get the body and mind to relax and to reduce the levels of stress hormones in the body so that your immune system is better able to fight off illness.
