The Center for Disease Control of the United States estimates that mental stress related illnesses account for about 75% of all doctor visits. The National Council on Compensation of Insurance goes even higher with around a 90% rate. Needless to say what people are thinking is causing them to feel bad and even get physical problems.
Here are some typical illnesses related to mental stress: Headaches, back and neck pain, fibromyalgia, jaw pain (TMJ syndrome), foot pain, irritable bowl syndrome, tachycardia, stomach ulcers, digestive disturbances, skin rashes, insomnia, chronic fatigue, tinnitus, dizziness, anxiety, depression, etc.
Research regarding mental stress:
Cancer - research - Extreme suppression of anger was the most commonly identified characteristic of 160 breast cancer patients. Journal of Psychosomatic Research (Impact Factor: 3.3). 02/1977; 21(5):395-9. DOI:10.1016/0022-3999(77)90048-4
According to the neuroscientific journal Neurologija, “In the chronic muscle pain syndrome . . . the most likely cause of the pain is a combination of muscle tension and muscle hypoxia [low oxygen levels]. This conclusion is supported by the finding of a pathological distribution of tissue oxygen pressure in painful muscles. . . .”
In 1994, the Journal of Behavioral Medicine published the results of a study that found, "... inhibiting the expression of angry feelings was the strongest predictor of reports of pain intensity and pain behavior..."
Science validates that skin reactions can be caused by thought, summarized in this quote from an article in the journal Dermatologic Clinics: "There is clinical and experimental evidence that the brain can start, influence, and stop biologic skin events."
Bruce Lipton's Biology of Belief
The idea that cancer and other physical ailments are strictly due to genetic predispositions and not emotions is called into question by the writings of Bruce Lipton, Ph.D. What Dr. Lipton showed in his book The Biology of Belief, is that the mind of a cell is located in its membrane not the nucleus or DNA. Simply put, the membrane of a cell interacts with the external environment and then determines how the DNA inside the cell should behave thus determining how the cell replicates itself and the tissue it is creating. This directly connects thought with things like cancer.
