What is Earthing?

Earthing is to physically and directly connect to the Earth so that the body may discharge static electricity build up, and resume uptake of the Earth's abundant source of negative ions.

Why Earthing?

Read More X

The society we live in is profoundly disconnected from the earth, and it appears to be absolutely no coincidence that large numbers of people are profoundly ill. We believe, based on a mountain of empirical research data (see below), that people may live healthier lives if they are regularly connected to the Earth.

Extensive research shows that benefits of earthing include improved mood, better circulation, reduced inflammation, reduced pain, and better quality, deeper sleep, and it presents itself as the radical solution that may help our deeply unhealthy society.

We believe so strongly in the benefits of earthing that we created Earthing Japan, so that we may spread the message of Earthing to Japan, and help educate people about how it can benefit health and improve sleep. Earthing Japan also makes available various Earthing products for sale within Japan. Please see the Earthing Japan community hub and online store: http://earthing.jp, and also see our earthing page for more information about Earthing and our Earthing activities.

The Studies

  • The Effect Of Grounding The Human Body On Mood

    Pleasant and positive moods statistically significantly improved among grounded — but not sham-grounded — participants.
    Results: The Grounded group showed a significant increase in the Pleasant– Unpleasant mood scale, indicating a more pleasant experience; a significant increase in the Positive–Tired mood scale, meaning feeling less tired and more positive; and a significant decrease in the Negative–Relaxed mood scale, becoming less negative and more relaxed. For the Shamgrounded group, the change in scores on the Pleasant–Unpleasant scale was significant, while for the other three tests there were no significant changes. Neither group had a significant change in the Arousal–Calm mood scale. Combining the results of these mood scales, it is apparent that the Grounded group had a more pleasant experience, felt more positive, less negative, and more relaxed than the control group.

  • The neuromodulative role of earthing

    Earthing significantly influences on the electrical activity of the brain. We hypothesize that earthing through its complex action on bioelectrical environment of human organism and alternations in electrolyte concentrations regulates correct functioning of the nervous system.

  • Emotional Stress, Heart Rate Variability, Grounding, and Improved Autonomic Tone: Clinical Applications

    When one grounds to the electron-enriched earth, an improved balance of the sympathetic and parasympathetic nervous system occurs. Previous investigations reported a marked change in biological parameters after about 20 to 30 minutes, others in several days, and a few others show a drastic change immediately at grounding (<2 sec). Skin conductance and electroencephalographic and electromyographic recordings showed the most immediate and profound changes.6,8 This study showed a positive trend in Heart Rate Variability that kept improving all the way to the end of the 40-minute period of grounding, suggesting a greater benefit with time.

  • Grounding after moderate eccentric contractions reduces muscle damage

    Grounding significantly reduced the loss of creatine kinase from the injured muscles indicating reduced muscle damage.

  • Changes in Pulse Rate, Respiratory Rate, Blood Oxygenation, Perfusion Index, Skin Conductance, and Their Variability Induced During and After Grounding Human Subjects for 40 Minutes

    These skin conductance changes suggest that grounding increases parasympathetic system function and/or reduces sympathetic system function. In that regard, the present results support previous studies reporting reduction in stress and improved sleep and relaxation.

  • The effect of Earthing (grounding) on human physiology

    Earthing decreased blood volume pulse (BVP) in 19 of 22 experimental subjects (p < 0.001) and in 8 of 30 controls (p ≅ 0.1, not significant); heart rate (HR) was not affected. From these results, it appears that earthing the human body has significant effects on electrophysiological properties of the brain and musculature, on the blood volume pulse, and on the noise and stability of electrophysiological recordings. Taken together, the changes in EEG, EMG, and BVP suggest reductions in overall stress levels and tensions, and a shift in autonomic balance upon earthing.

Studies on negative ions and free radicals

While the active mechanism behind the health enhancing effects of earthing is as yet still uncertain, it has been suggested that it may be due to the uptake of negative ions from the earth, which bind to free radicals within the body, thereby reducing inflammation.
