The described devices, “grounded [ungrounded] stimulation devices” and “devices with [without] EMF removal”, assist in maintaining and/or restoring bodily health primarily via two modes of operation:In one set of embodiments, by reducing or removing the effects of electromagnetic fields (EMFs) encountered in daily life, through grounding.In another set of embodiments, by stimulating and/or encouraging bodily healing processes through the supply of free electrons, at Schumann frequencies.The embodiments function by allowing or increasing, respectively, the flow of low-current, low-voltage current into or out of the body, at levels safe for humans and animals, through conductive materials in electrical contact with the body. These devices use conductive materials incorporated into and/or comprising handheld, wearable or other items that directly contact the body, including shavers, clothing, shoes, mousepads, footstools, bedding, jewelry and collars. Certain devices allow the addition of heat/cold.
