Water which seeps down into the earth collects into underground rivers and streams, depending on the composition of the earth. The radiation or energy is probably caused by the friction between the water and the rock. However, it is clear that people who remain in these areas react to them. The body becomes unusually tense. Symptoms such as sleep problems, headaches, migraines and high blood pressure occur. Circulation problems, cramp, joint and back pains, nightmares, shortness of breath, heavy legs, gout and rheumatism can also arise. Particularly extreme cases can result in tumours and even cancer.
