Relaxation Techniques

“Guided imagery, autogenic training, biofeedback, and hypnotherapy are all techniques that can enable us to reach deep states of relaxation. It was once thought that the autonomic nervous system and things such as heart rate and blood pressure could not be voluntarily controlled. But it turns out that with proper training we can, for example, be trained to slow our heart rate and lower our blood pressure. We can dilate our peripheral blood vessels and make our cold hands warm. This type of training can also be used to control our response to pain and thereby change our experience of pain.”
