Health Psychology is concerned with using psychological interventions in order to promote, maintain, and improve health and wellbeing. Often this can be using psychological theory and methods to help people adapt to, or recover from illness.
Hypnotherapy can be used to make changes in your life, and works in conjunction with health psychology. Hypnotherapy can be an effective method of managing pain, relieving the symptoms of IBS, and habit reversal (i.e. stopping smoking).
