The energy emitted by the earth at a specific location which affects the normal human body function is termed as geopathic stress (GS). Scientific studies of the exact nature and characteristic of geopathic stress are sparse and yet to receive appropriate attention. Some studies indicate that geopathic stress may be of electromagnetic nature. This paper attempts to make use of 'Naav meter and Proton Magnetometer' to study the nature of geopathic stress. The results indicate that this stress is in the form of Elctro magnetic waves.
