I have been sensitive to EMF most all my life. I think I was worse when candida was at its peak. But maybe one can be electrically sensitive just because they are. Exactly why is unknown. But I think most everyone I have known that was sensitive also had a candida problem. Maybe the toxins from the candida irritate the nervous system so that it reacts more to EMF than what is normal.
ps- I tried a scalar wave device and it gave me horrible nightmares and so I threw it away fearing anyone I gave it to would do the same thing to them. I do not now believe that anything you have on or near you can protect you from EMF other than a Faraday cage. Sellers prey on peoples desperation to try anything.
