A 2016 study confirms once again what we have known for years − that grounding indoors in the presence of common electromagnetic fields (EMFs) is safe and protective.
The new study, conducted by University of Oregon exercise physiologist Dick Brown, further disqualifies the baseless idea purveyed by various “experts” that Earthing indoors can be harmful because of EMFs.
For the study, Dr. Brown individually exposed 50 participants (male and female, ages 12 to 79) to EMFs generated by electric equipment in his home office. The equipment included a printer, scanner, cordless phone, lamp, computer, and computer monitor. These devices, like many other household appliances and wiring, produce 60Hz frequency alternating current (AC) EMFs.
The voltage and currents induced on the participants’ body by the equipment was first measured with a voltmeter when participants were ungrounded and then again when grounded. Grounding was achieved via an Earthing (electrode) patch placed on the palm of the left hand and connected to the ground port of a grounded wall electric outlet.
The results: A significant drop – by a factor of 58 on average – of measured body AC voltage when subjects were grounded compared to not being grounded. Current measurements were taken when participants touched a desk lamp, and again when they moved their hand about 12 inches away from the lamp, and then three feet away.
The highest average current − 2.62 microamperes − measured on grounded participants occurred, as expected, when touching the lamp. What does that number mean? The Electrical Safety manual of the U.S. National Institute for Occupational Safety (http://www.cdc.gov/niosh/docs/2009-113/pdfs/2009-113.pdf, p. 7) states that a current below 1 milliampere is generally not perceptible. There are one thousand microamperes in a milliampere.
Thus, the recognized perception level is at least 382 times larger than the average current measured in the study when touching the lamp and 1,852 times larger than the measurement at three feet distance from the lamp.
“The study indicates clearly that normal levels of electromagnetic fields existing in an office setting in houses are too low to produce harmful currents when a person is grounded,” concluded Dr. Brown.
The decreased voltage induced on the body by grounding in this experiment is comparable to results obtained by electrical engineer Roger Applewhite in a hotel room setting in 2005. In that experiment, grounding produced a voltage drop by a factor of 71 in comparison to being ungrounded.
EMFs are present whether you are grounded or not. Grounding, however, reflects the common AC voltage from your body like a mirror so it does not penetrate.
Even Premature Babies Benefit
Grounding studies have been conducted in indoor settings full of common electromagnetic fields. One impactful study published in 2017 showed potentially life-saving benefit for the most vulnerable of humans: premature babies. The study, done at the Pennsylvania State University Children’s Hospital in Hershey, demonstrated that grounding had an immediate and significant improvement on autonomic nervous system functioning critical to inflammatory and stress responses.
Twenty infants were involved in the study. Skin voltage was measured while the babies were ungrounded and then grounded. When grounded, their skin voltage levels dropped instantly to almost zero! And in a setting filled with electrical medical equipment! Click here to read an article we have written about the study.
These kinds of results speak loud and clear to the safety issue of Earthing. Yes, it is wonderful to be outdoors barefoot in Nature and ground yourself. Yet, by plugging into a properly grounded wall outlet indoors you can safely and beneficially ground yourself. In the process, you become buffered from common AC voltage surrounding you that emanates from wires, and most electronic equipment and appliances. You instantly equalize electrically with the Earth’s natural energy. You become an extension of Mother Earth.
But more important than fending off AC voltage, grounding reduces inflammation and pain, calms your nervous system, and improves your blood flow. You become healthier and look healthier.
Please ignore the ignorant opinions of bloggers and others who say that Earthing indoors is unhealthy because of the EMFs that you absorb like an antenna. The truth is just the opposite. And grounded antennas, for the uninformed, cannot absorb EMFs.
What about the Wi-fi and cellphone frequencies all around us? First and foremost, they have nothing to do with Earthing. Earthing works in environments full of such frequencies. What we tell everyone who expresses concern about any potential harm from these frequencies is that they should limit their exposure and, very importantly, ground themselves as much as possible. While the protective potential of Earthing has not been tested specifically against these frequencies, our research has taken place in environments full of all kinds of frequencies, and consistently produces broad health and healing benefits and significantly positive changes in the physiology.
