Should hospitals protect from geopathogenic zones? – PubMed – NCBI
Veľká Téma : Geopatogénne zóny

The belief that geopathogenic zones exist and could cause morbidity is
widespread. It is increasing even among physicians. Presently, in health
care it is going to even gain an economical dimension by causing
investment costs for claimed protective means and by influencing
hospital planning, design and management. Therefore, this issue is no
longer just a private borderline issue but has become publicly relevant.
In view of the fact that relevant studies are lacking, it deserves
scientific clarification. In a double-blind study this hypothesis was
tested by two different approaches: First, it was investigated whether
location-bound biologic effects could be identified at all. To remain
independent from dowsers, an investigation area of 35 m(2) was chosen
which was large enough to ensure the presence of at least one postulated
adverse zone. This area was scanned in 0.5 m intervals by monitoring
bioparameters such as skin resistance, reaction time and heart rate
variability in 43 volunteers. Skeptics were excluded. Location-dependent
changes were investigated by point-by point analysis of local data
distributions and by analysing the two-dimensional spatial distributions
of the measured bioparameters by cross-correlation analysis. In a
second approach, 5 independent experienced dowsers were asked to locate
geopathogenic zones within the area both to verify the adequate choice
of the area and to correlate the pattern of dowser’s scorings with the
patterns of biosignal distributions. Neither of these approaches showed
statistical significant differences. The investigation did not confirm
the hypothesis that local geopathogenic zones existed and, hence, would
need protective actions.
