Each person’s sensitivity is very different. The most common disorders in people who spend long periods of time over groundwater currents are insomnia, fatigue, headache, or nervousness. In general, the body weakens and the process of recovery from disease also suffers.
The greatest researcher on the effects of positive air ionization, such as that produced by groundwater flows, is Professor Emeritus Dr. Albert Paul Krueger of the University of California. The professor indicated that the positive ionization of the air increases the production of serotonin, so that mood, anxiety, exhaustion and happiness are altered. In the long term, insomnia, depression, psychophysical exhaustion and respiratory ailments could be induced.
In general, recovery usually begins soon after leaving the spaces above the groundwater streams. Other times, it starts after a few weeks or months.
