Introduction
The mind and body interact in powerful ways that affect a person's health. The Overview of the Digestive System is profoundly controlled by the mind (brain), and anxiety, depression, and fear dramatically affect the function of this system. Social and psychologic stress can trigger or aggravate a wide variety of diseases and disorders, such as Most people, on the basis of either intuition or personal experience, believe that emotional stress can cause or alter the course of even major physical diseases. How these stressors do this is not clear. Emotions obviously can affect certain body functions, such as heart rate, blood pressure, sweating, sleep patterns, stomach acid secretion, and bowel movements, but other relationships are less obvious. For example, the pathways and mechanisms by which the brain and immune system interact are only beginning to be identified. It is remarkable that the brain can alter the activity of white blood cells and thus an immune response because white blood cells travel through the body in blood or lymph vessels and are not attached to nerves. Nevertheless, research has shown that the brain does communicate with the white blood cells. For example, Depression may suppress the immune system and make a person more susceptible to infections such as the common cold. Stress can cause physical symptoms even though no physical disease may be present because the body responds physiologically to emotional stress. For example, stress can cause Overview of Anxiety Disorders , which then triggers the Mind-Body Medicine refers to therapeutic techniques based on the theory that mental and emotional factors can influence physical health. Behavioral, psychologic, social, and spiritual methods are used to try to preserve health and prevent or cure disease. The mind-body interaction is a two-way street. Not only can psychologic factors contribute to the onset or aggravation of a wide variety of physical disorders, but also physical diseases can affect a person's thinking or mood. People with life-threatening, recurring, or chronic physical disorders commonly become depressed. The depression may worsen the effects of the physical disease and add to a person's misery.
