Abstract
Multi-disciplinary research has revealed that electrically conductive contact of the human body with the surface of the Earth (grounding or earthing) produces intriguing effects on physiology and health. Such effects relate to inflammation, immune responses, wound healing, and prevention and treatment of chronic inflammatory and autoimmune diseases. The purpose of this report is two-fold: to 1) inform researchers about what appears to be a new perspective to the study of inflammation, and 2) alert researchers that the length of time and degree (resistance to ground) of grounding of experimental animals is an important but usually overlooked factor that can influence outcomes of studies of inflammation, wound healing, and tumorigenesis. Specifically, grounding an organism produces measurable differences in the concentrations of white blood cells, cytokines, and other molecules involved in the inflammatory response. We present several hypotheses to explain observed effects, based on current research results and our understanding of the electronic aspects of cell and tissue physiology, cell biology, biophysics, and biochemistry. An experimental injury to muscles, known as delayed onset muscle soreness, has been used to monitor the immune response under grounded versus ungrounded conditions. Grounding reduces pain and alters the numbers of circulating neutrophils and lymphocytes, and also affects various circulating chemical factors related to inflammation.

Introduction – The effects of grounding (earthing) on wound healing
Grounding or earthing refers to direct skin contact with the surface of the Earth, such as with bare feet or hands, or with various grounding systems. Subjective reports that walking barefoot on the Earth enhances health and provides feelings of well-being can be found in the literature and practices of diverse cultures from around the world.1 For a variety of reasons, many individuals are reluctant to walk outside barefoot, unless they are on holiday at the beach. Experience and measurements show that sustained contact with the Earth yields sustained benefits. Various grounding systems are available that enable frequent contact with the Earth, such as while sleeping, sitting at a computer, or walking outdoors. These are simple conductive systems in the form of sheets, mats, wrist or ankle bands, adhesive patches that can be used inside the home or office, and footwear. These applications are connected to the Earth via a cord inserted into a grounded wall outlet or attached to a ground rod placed in the soil outside below a window. For the footwear applications, a conductive plug is positioned in the shoe sole at the ball of the foot, under the metatarsals, at the acupuncture point known as Kidney 1. From a practical standpoint, these methods offer a convenient and routine, user-friendly approach to grounding or earthing. They can also be used in clinical situations, as will be described in the section entitled Summary of findings to date.1
Recently, a group of about a dozen researchers (including the authors of this paper) has been studying the physiological effects of grounding from a variety of perspectives. This research has led to more than a dozen studies published in peer-reviewed journals. While most of these pilot studies involved relatively few subjects, taken together, the research has opened a new and promising frontier in inflammation research, with broad implications for prevention and public health. The findings merit consideration by the inflammation research community, which has the means to verify, refute, or clarify the interpretations we have made thus far.
Grounding reduces or even prevents the cardinal signs of inflammation following injury: redness, heat, swelling, pain, and loss of function (Figures 1 and 2). Rapid resolution of painful chronic inflammation was confirmed in 20 case studies using medical infrared imaging (Figure 3).2,3



Our main hypothesis is that connecting the body to the Earth enables free electrons from the Earth’s surface to spread over and into the body, where they can have antioxidant effects. Specifically, we suggest that mobile electrons create an antioxidant microenvironment around the injury repair field, slowing or preventing reactive oxygen species (ROS) delivered by the oxidative burst from causing “collateral damage” to healthy tissue, and preventing or reducing the formation of the so-called “inflammatory barricade”. We also hypothesize that electrons from the Earth can prevent or resolve so-called “silent” or “smoldering” inflammation. If verified, these concepts may help us better understand and research the inflammatory response and wound healing, and develop new information on how the immune system functions in health and disease.

Conclusion – FULL ARTICLE HERE
Accumulating experiences and research on earthing, or grounding, point to the emergence of a simple, natural, and accessible health strategy against chronic inflammation, warranting the serious attention of clinicians and researchers. The living matrix (or ground regulation or tissue tensegrity-matrix system), the very fabric of the body, appears to serve as one of our primary antioxidant defense systems. As this report explains, it is a system requiring occasional recharging by conductive contact with the Earth’s surface – the “battery” for all planetary life – to be optimally effective.
