Heavy Metal Toxicity Increases Harmful Effects of EMFs

28-08-2020Somewhere between 3% to 35% of people experience mild, moderate or severe EHS. Many EHS symptoms are the same as the symptoms of a chronic viral or bacterial illness, and it seems they are related. This is likely because of the link between EMFs, heavy metals and harmful microbes. Most of those who suffer from severe EHS also have high metal
