Geopathic Stress has been studied for over 1000 years.
Most of the studies have been conducted in Germany and other Eastern European countries.

Here are some of their conclusions:
Women are considered more likely to be at risk from geopathic stress because their hormonal systems are more susceptible. Foresight, the British pre-conception care organization, now suggest that all couples trying for a baby should get their homes checked for geopathic stress and electromagnetic stress.

The respected Austrian researcher Kathe Bachler surveyed over 3000 school children, and showed 95% of children with learning difficulties, hyperactive tendencies or continuous bad behavior, either slept or had their school desks (or both) in locations with marked GS. When she moved the children into stress free places, they nearly all showed a marked improvement, often going from bottom to top of their class in one term. She concluded that GS affects a high proportion of children who continuously play truant or who are refused places in ordinary schools due to misbehavior. Class teachers in schools suffering with GS have a high rate of absenteeism.
Exposure to GS during childhood can make a person particularly sensitive to GS for the rest of their life, as well as prone to choose to inhabit places with a similar and familiar level of geopathic stress.

The World Health Organization estimates that 30% of offices, hotels, institutions and industrial premises have SBS. causing: headaches, tension between staff, lethargy, respiratory infection, dry skin and throat, eye symptoms, loss of concentration, depression, stress and fatigue, leading to a high rate of absenteeism, increased staff turnover, and lowered morale. While electro-, micro-, and radio wave and chemical pollution are undoubtedly major factors, SBS is generally rooted in the presence of GS.

German physicist Robert Endros and Professor KE Lotz analyzed 400 deaths due to cancer and revealed that 383 cases were related to living over geological faults, underground water veins and disturbances of the natural geomagnetic field.

According to Austrian researcher Baron von Pohl, earth radiation almost always causes cancer.  In the 1940s he proved to the Central Committee for Cancer Research in Berlin that one was unlikely to get cancer unless one spent some time in Geopathic Stress.

Dr. Hubank of Vienna found that the altered electrical and magnetic field above a Geopathic Stress zone changed the electrical impulses passing along the nerves of the body. This altered information resulted in the dysfunction of individual organs and also explained the high number of diseases. He proved that it weakened the immune system in people who had been exposed. 

Dr. Hans Nieper, M.D., stated that 92% of all his cancer patients and 75% of his MS patients live in a Geopathic Stress zone.

Dr. Hager, M.D., found Geopathic Stress in the homes of over 5,000 cancer cases investigated.

Dr. Ernst Hartmann wrote that the first thing to be adversely effected was the immune system, as a result of this, the individuals that were placed in these Geopathic Stress disturbed areas soon lost their ability to defend themselves against harmful bacteria that previously they were able to withstand.

"Cancer is a disease of location triggered off by Geopathic Stress. We all produce cancerous cells on a regular basis, but they are continuously destroyed by our body’s immune system.”
Dr. Ernst Hartmann, MD.
