The miHealth is just one componet of the NES Total Wwellnes System. When paired to the ProVision software you simply hold it for thirty seconds and it scans your body to reveal where energy information may be challenging your overall health and wellbeing. Used by itself, the NES miHealth device can be used to send correct information allowing the body to dislodge incorrect or fragmented information that may be causing pain, digestive issues. chronic fatique or just an overall sense of dis-ease.. Amazing as that sounds ....it gets better! Clients with TMJ, sports injuries, carpel tunnel, constipation and range of motion issues have noticed a marked improvement in 10-20 min! I also use the miHealth anti-aging and skin fuctions when giving a facial to adress wrinkles and firmness.
