Lowering you vibrational emotions lowers your resonance and can lead to stress related diseases. The article below describes how disease can actually be measured in the body with sensitive machines. Unlike star Trek we have limited capabilities. However scientific research does suggest that it is possible to measure the frequency of disease. The foundation of Energy therapy is to help raise the vibrations in the body so that disease can be eliminated in the body. Light workers usually emphasize and focus on the importance on staying away from lower vibrational energies like anger and fear. This article below taking from  goes into greater details on the study of human frequency.
Human Electrical Frequencies and Fields
Dr. Robert O. Becker, in his book The Body Electric, tells us that the human body has an electrical frequency, and also that much about a person's health can be determined by its frequency levels.
In addition to his plant studies, Tainio developed a way to use his machine to measure human electrical vibrational frequency by taking readings on various points of the body and averaging those numbers together. His measurements indicate that the daytime frequency of a healthy human body vibrates in the range of 62 to 68 MHz.
Intriguing as Tainio’s research is, its foundation may have been laid in the early years of the 20th century by Dr. Royal R. Rife, M.D. (1888-1971). Dr. Rife conducted research with a machine he developed called a “frequency generator” that applies currents of specific frequencies to the body. He concluded that every disease has a specific frequency.
According to Dr. Rife every cell, tissue and organ has its own vibratory resonance. Working with his frequency generator, he found that specific frequencies would destroy a cancer cell or a virus. His research demonstrated that certain frequencies could prevent the development of disease, and that others would neutralize disease.
Bjorn Nordenstrom, a radiologist from Stockholm, Sweden, discovered in the early 1980s that, by putting an electrode inside a tumor and running a milliamp of DC current through the electrode, he could dissolve a cancer tumor and stop its growth. He also found that the human body had electropositive and electronegative energy fields.
Studies conducted in 1992 by Tainio Technology, as an independent division of Eastern State University in Cheny, Washington, reinforce the findings of these earlier researchers. Tainio and colleagues determined that when a person's frequency drops below the optimum healthy range, the immune system is compromised. Findings supported by this research indicate that:
Human cells can start to change (mutate) when their frequency drops below 62MHz.
58 MHz is the frequency of your body when you have a cold or the flu.
When candida is present within your body, you vibrate at a frequency of 55MHz.
52 MHz is the frequency of a body with Epstein-Barr virus present.
42 MHz is the frequency of a body wherein cancer can appear.
When the death process begins - the frequency has been measured at 20 MHz.
The North American Nurses Diagnosis Association (NANDA) recognizes energy therapy as an intervention representing a specific theory: human energy field theory (HEFT). This therapy is related to the approved nursing diagnosis of energy field disturbance 1.8 (NANDA, 1995/1996).
