Modern psychoimmune research shows that when a person suffers from a disease, if he has the confidence to overcome it, then he can effectively mobilize the body’s immune power and promote the early recovery of the body’s health. In order to figure out the relationship between mental state and physical and mental health, scientists have done a lot of studies and experiments. One test is a small dose of cold virus drops to 420 volunteers, when told the truth afterwards, the high degree of mental tension of the subjects, almost all were infected by the virus; while the mood of those who are open, only 25% of people have a mild runny nose symptoms, 75% of people produced antibodies to resist the virus. In addition, the Royal College of Physicians also did a related survey, they have more than five thousand cancer patients after surgery to track the survey, found that always remain optimistic and believe that they can beat cancer, the survival rate of more than ten years actually reached 31%; while those who are mentally depressed or even desperate, many died soon after the operation. According to experts, those who remain optimistic after the disease can overcome cancer and regain health because the mental factor is closely related to the immune function of human body, and a positive mental state can not only make life happy, but also enhance the body’s ability to resist diseases. Thus, it can be seen that a good or bad mental state can indeed influence the health of human body. Scientists have discovered in numerous experiments that different mental activities can cause nerve fibers to release specific and different chemical messages that act on the immune and endocrine systems, thus creating a new branch of medicine – psychoimmunology. Experts tell people that the positive mental state of people who dare to fight against diseases can directly affect the body’s ability to resist diseases, especially enhance the tolerance and resistance to diseases, so that even if they are suffering from diseases, they can often regain their health and even extend their life. The best proof of this is that many cancer patients have beaten the cancer and regained the miracle of life through the anti-cancer clubs all over the world. If we lack the spirit of resistance, we will not only affect the immune function of the body, but also reduce the inherent resistance in the body, resulting in the body constantly reducing the substances with the ability to resist disease, passively enduring the torture of the disease and giving up the right to health.
