"Relaxation techniques include progressive relaxation, guided imagery, biofeedback, self-hypnosis, and deep breathing exercises. The goal is to consciously produce the body’s natural relaxation response, characterized by slower breathing, lower blood pressure, and a feeling of calm and well-being. Relaxation is more than a state of mind; it physically changes the way your body functions. When your body is relaxed, breathing slows, blood pressure and oxygen consumption decrease, and some people report an increased sense of well-being. Relaxation techniques may be used to release tension and counteract the ill effects of stress. They are also used to induce sleep, reduce pain, and calm emotions."
