Many research studies report that pain, chronic conditions and even some diseases and other disturbances in our bodies are often caused by chronic inflammation. Such inflammation may be caused by positively charged molecules OR free radicals. When you make direct contact with the earth, such as by being barefoot outdoors or by wearing grounded shoes, the negatively-charged electrons from the earth enter your body. Several studies suggest that grounding reduces inflammation, a condition that is not a disease but often accompanies disease and usually causes discomfort or pain. Inflammation also tends to beget inflammation because inflamed tissue is more easily irritated than tissue that is not inflamed. The body, therefore, continues to have inflammation when its original cause is removed. While the reason is not fully known, it appears that grounding may reduce chronic inflammation and it may be that excess positive charge may be the cause of chronic inflammation.
