A method to speed recovery from acute injury and/or reduce and prevent chronic inflammation in an animal or human is disclosed. The method includes providing a grounded plane, conductively coupling said animal or human to the grounded plane to conduct the earth's mobile negative surface charge of free electrons from the earth to said animal or human in order to provide the body with an abundant supply of free electrons to reduce residual immune system produced reactive oxygen specie free radicals and prevent the same from oxidizing healthy tissue and exhibiting chronic inflammation in said animal or man. Applying earth's free electrons to the human body for prevention of chronic inflammation and therapeutic reduction of inflammation is described. Further described are methods to apply and maintain earth's mobile free electron charge on an animal or human while residing in modern home or work environments or in a treatment facility.
